Best 18 X 9 50 8 Tire for Lawn and Garden Equipment

Best 18 X 9 50 8 Tire

A strong 18×9.50-8 tire should match your mower or garden equipment, its load needs, and the kind of ground it crosses; the MaxAuto 4-ply set is a well-documented choice for many lawn and garden users. This roundup compares ten products in the requested size, including tubeless turf tires, smooth and turf-specific options, a tire-and-rim package, and deeper-lug 6-ply tires. Their listed capacities range from 225 to 1,320 pounds, but those figures are not directly interchangeable: check the exact tire and equipment requirements, including inflation guidance.

The listings also differ in what comes in the package, so confirm whether you need tires alone or a mounted wheel assembly. Use the comparisons below to narrow your choices by tread style, construction, load rating, and fit.

The MaxAuto 4-Ply Lawn Tire leads this roundup because it is listed as a tubeless 18×9.50-8 lawn and garden tire with a 1040-pound maximum load at 24 psi, a 7-inch rim width, and a 5 mm tread depth. Its stated applications include riding mowers, lawn tractors, golf carts, and utility vehicles. Choose it when you want a clearly specified general-purpose tire pair; consider a 6-ply lug option instead if your priority is deeper, angled traction rather than turf-oriented use.

Detailed Reviews: Best 18 X 9 50 8 Tire

MaxAuto 4-Ply Lawn Tire

#1 · Best Overall

1. MaxAuto 4-Ply Lawn Tire

  • Load Capacity: 1040 lb
  • Size: 18X9.50-8
  • Rim Size: 8 in

Best for: Measured turf and utility replacement.

Why it ranks #1: This tubeless 4-ply lawn tire lists a 1040-pound maximum load at 24 psi, 5 mm tread depth, and a 7-inch rim width.

A specified 0.2-inch tread depth, 7-inch rim width, and 17.94-inch outer diameter give the MaxAuto 18×9.50-8 pair useful fit and tread details up front. Its 1040-pound maximum load and tubeless 4-ply construction make it a clearly documented option for lawn, garden, and listed utility-vehicle applications.

MaxAuto describes a unique tread pattern intended to increase ground friction, reduce tire noise, and support cooling and drainage, connecting the design to traction and ride comfort during lawn work. The 4-ply tubeless build avoids an inner tube, while the 7-inch rim-width specification, 8-inch rim size, and 17.94-inch outer diameter help with replacement checks. Its stated maximum is 1040 pounds at 24 psi; the tire is marked for non-highway service.

Pros
  • 1040-pound maximum load at 24 psi
  • 0.2-inch tread depth specified
  • 17.94-inch outer diameter and 7-inch rim width listed
  • Tread pattern is described as supporting friction, drainage, and reduced noise
Cons
  • Marked for non-highway service, so it is not specified for highway use.

Skip it if you need a deeper 0.63-inch tread and directional pulling lugs; MaxAuto 18×9.50-8 Super Lug tires list those features.

This MaxAuto pair suits buyers replacing lawn, garden, or listed utility-vehicle tires who value detailed dimensions and a 1040-pound rating. Keep its non-highway designation and 8-inch rim size in mind when checking the intended application.

MAXROLLORS Turf-S Tire

#2 · Highest Capacity

2. MAXROLLORS Turf-S Tire

  • Load Capacity: 1040 lb
  • Size: 18×9.50-8 Turf-S
  • Rim Size: 8 in

Best for: Higher-capacity turf tractor pair.

Why it ranks #2: Its 1040-pound capacity and 4-ply tubeless construction suit garden tractors and riding mowers; the listing also identifies a Turf-S pattern.

A listed 1040-pound load capacity sets the MAXROLLORS 18×9.50-8 pair apart for buyers prioritizing a higher stated carrying limit in a garden-tractor tire. Its 4-ply tubeless construction and Turf-S pattern are also identified, linking the capacity to a lawn-and-garden application rather than an unspecified general tire.

The 18×9.50-8 size and 8-inch rim specification give buyers the core dimensions for checking a replacement, while the 1040-pound capacity provides a clear load figure to compare with equipment needs. MAXROLLORS describes the tire as 4-ply tubeless and names a Turf-S tread pattern; its supplied product facts also cite abrasion and puncture resistance, stable ground traction, and straightforward installation. Those traits suit routine lawn-and-garden use, though no tread depth or overall diameter is provided here.

Pros
  • 1040-pound listed load capacity
  • 4-ply tubeless construction
  • Turf-S pattern specified
  • Product facts cite abrasion resistance, puncture resistance, and stable traction
Cons
  • No tread depth or overall tire diameter is listed in the supplied specifications.

Skip it if you need a stated tread depth and overall diameter; MaxAuto 18×9.50-8 4-ply tires provide both measurements.

Choose this pair for lawn or garden tractor use when 18×9.50-8 sizing and a 1040-pound listed capacity suit the equipment. Buyers needing precise tread-depth or overall-diameter figures will find those measurements unlisted here.

TRIBLE SIX Tire and Rim

#3 · Wheel-Included Set

3. TRIBLE SIX Tire and Rim

  • Load Capacity: 1040 lb
  • Size: 18×9.50-8
  • Rim Size: 8 in

Best for: Lugged-wheel replacement set.

Why it ranks #3: The 4-ply 18×9.50-8 package lists a 1040-pound capacity and includes tires with a rim, useful when replacing wheel assemblies.

Unlike tire-only listings, this TRIBLE SIX package explicitly includes tires with rims, making it relevant to buyers seeking a wheel-and-tire assembly. Its stated 4-lug layout, 4-inch PCD, 2.83-inch center bore, and 1040-pound maximum load give specific connection and capacity details to assess.

The listing calls out an 8-inch rim width, 16-inch outside diameter, 9.5-inch section width, and 0.2-inch tread depth, giving buyers several measurements for a replacement check. A 4-lug pattern with a 4-inch PCD and 2.83-inch center bore describes the mounting arrangement, while the 0.59-inch lug valve hole adds another fit detail. TRIBLE SIX also describes the tread as increasing grip and weight sharing on wet grass, slopes, and hills while minimizing grass damage; verify assembly dimensions against the equipment.

Pros
  • Package includes tires with rims
  • 1040-pound maximum load listed
  • 4-lug, 4-inch PCD, and 2.83-inch center bore specified
  • Tread is described for grip on wet grass, slopes, and hills
Cons
  • The listed 16-inch outside diameter differs from the 18-inch size stated in the product title.

Skip it if you need a tire-only 18-inch-diameter listing; Carlisle Smooth Lawn & Garden Tire is listed as 18×9.50-8.

This TRIBLE SIX assembly fits buyers seeking a rim-and-tire package with mounting measurements and a stated 1040-pound capacity. Its listed 16-inch outside diameter conflicts with the title’s 18-inch sizing, so resolve that discrepancy before selecting it.

TUFFIOM Turf Tire

#4

4. TUFFIOM Turf Tire

  • Load Capacity: 815 lb
  • Size: 18×9.50-8
  • Rim Size: 8 in

Best for: Straightforward 815-pound turf pair.

Why it ranks #4: This 4-ply tubeless lawn and garden tire set matches the requested size and lists an 815-pound carrying capacity.

TUFFIOM lists an 815-pound carrying capacity for this two-tire, 18×9.50-8 set, giving lawn-mower and garden-tractor buyers a concrete load figure to check. The 4PR turf construction and tubeless design identify its intended lawn-and-garden role, with compatibility described for most utility vehicles in that category.

The 8-inch rim size and 18×9.50-8 tire size provide the principal dimensions for replacement checks, while the 815-pound capacity helps buyers compare the tire with their equipment’s load needs. TUFFIOM describes durable materials for lawn mowing and gardening and specifies a 4PR turf tire that is tubeless. Together, those details point to a conventional lawn-and-garden replacement without requiring an inner tube. The supplied information does not give tread depth, pressure, or overall diameter.

Pros
  • Set of two tires
  • 4PR turf tire construction
  • Tubeless design
  • 815-pound carrying capacity listed
Cons
  • The supplied specifications omit tread depth, tire pressure, and overall diameter.

Skip it if you need detailed tread and diameter measurements; MOTOOS 18×9.50-8 tires list tread depth and overall diameter.

For a buyer replacing lawn-mower or garden-tractor tires, TUFFIOM offers a two-piece 18×9.50-8 tubeless turf set with an 815-pound capacity. Check equipment load needs carefully, since several key dimensions are not supplied.

MOTOOS 4-Ply Lawn Tire

#5

5. MOTOOS 4-Ply Lawn Tire

  • Load Capacity: 815 lb
  • Size: 18×9.50-8
  • Rim Size: 8 in

Best for: Tubeless lawn mower replacement pair.

Why it ranks #5: The tubeless pair specifies a 815-pound maximum load, 4.8 mm tread depth, and 24 psi pressure for lawn use.

A 4-ply tubeless construction paired with a stated 815-pound load capacity gives this MOTOOS two-tire set a practical role on lawn equipment needing the 18×9.50-8 size. The listed 0.19-inch tread depth and 24 psi pressure specification also make its operating details clear for a replacement decision.

The 8-inch rim diameter and 7-inch rim-width specification help identify the wheel dimensions this tire is intended to fit, while the 18.27-inch overall diameter and 8.77-inch section width clarify its listed envelope. MOTOOS specifies a 4PR tubeless build and rubber with puncture, abrasion, and aging resistance, supporting a tire choice aimed at repeated lawn use without an inner tube. The set includes two tires, useful when replacing a pair; the stated maximum load is 815 pounds.

Pros
  • Set includes two 18×9.50-8 tires
  • 4PR tubeless construction
  • 815-pound maximum load capacity
  • Rubber is described as puncture-, abrasion-, and aging-resistant
Cons
  • The 815-pound maximum load is lower than the 1040-pound rating listed for several alternatives.

Skip it if you need a stated 1040-pound capacity; MaxAuto 18×9.50-8 4-ply tires list that higher limit.

For a lawn mower owner replacing two 18×9.50-8 tires, this MOTOOS set offers tubeless 4-ply construction and documented dimensions. Its 815-pound maximum load is an important boundary when matching it to the equipment’s requirements.

Carlisle Turf Saver

#6 · Turf-Specific Option

6. Carlisle Turf Saver

  • Size: 18/9.50-8
  • Rim Size: 8 in

Best for: Carlisle Turf Saver replacement.

Why it ranks #6: This Carlisle 18/9.50-8 tire is explicitly identified as a Turf Saver lawn and garden tire, though the listing gives few performance specifications.

The Turf Saver name identifies this Carlisle 18/9.50-8 tire as a lawn-and-garden option for buyers seeking a named turf tire rather than a super-lug or ATV pattern. Its listed 8-inch rim size and 18/9.50-8 sizing provide the key basic dimensions for a replacement check.

Carlisle specifies the Turf Saver model as size 18/9.50-8 with an 8-inch rim, giving buyers the principal sizing information available in the supplied listing. The lawn-and-garden designation helps distinguish its intended category from the explicitly named ATV, trencher, and deep-lug alternatives. However, no load capacity, tread depth, pressure, ply rating, or package contents are supplied here, limiting how much can be assessed beyond size and tire category before selection.

Pros
  • Turf Saver lawn-and-garden tire designation
  • 18/9.50-8 size listed
  • 8-inch rim size specified
  • Carlisle brand and model number provided
Cons
  • Load capacity, tread depth, pressure, and ply rating are not listed in the supplied specifications.

Skip it if you need a stated load rating and ply count; MaxAuto 18×9.50-8 4-ply tires list both specifications.

This Carlisle is for lawn-and-garden buyers considering a Turf Saver in the listed 18/9.50-8 size with an 8-inch rim. Because key load and construction figures are not supplied, select it only when those details are not required for evaluation.

Carlisle Smooth Tire

#7 · Smooth Tread

7. Carlisle Smooth Tire

  • Size: 18/9.50-8 B
  • Rim Size: 8 in

Best for: Smooth-tread lawn replacement.

Why it ranks #7: Its exact 18×9.50-8 size and smooth lawn-and-garden designation make it a specialized option; the listing says the rim is not included.

A smooth tread gives the Carlisle 18×9.50-8 Lawn & Garden tire a distinct option for buyers seeking a non-lugged pattern. The listing identifies an 8-inch rim size and specifies that this is a tire only, so shoppers can plan around using or sourcing a compatible rim separately.

The smooth lawn-and-garden designation distinguishes this Carlisle tire from the deep-lug and knobby patterns in this roundup, making tread style the central application consideration. Its listed 18×9.50-8 size and 8-inch rim size provide basic replacement dimensions. Because the package includes the tire only and excludes the rim, installation planning needs a compatible wheel already available or sourced separately. The supplied information does not provide load capacity, tread depth, pressure, or ply rating.

Pros
  • Smooth lawn-and-garden tread designation
  • 18×9.50-8 size listed
  • 8-inch rim size specified
  • Tire-only package clearly identified
Cons
  • No rim is included, so a compatible rim is needed separately.

Skip it if you need a deeper lug pattern for pulling work; MaxAuto 18×9.50-8 Super Lug tires list 0.63-inch directional tread.

Choose this Carlisle for a buyer seeking a smooth-pattern lawn-and-garden tire and who already has, or will source, a compatible 8-inch rim. Its supplied specifications do not state load capacity or tread depth.

MaxAuto 6-Ply Super Lug

#8

8. MaxAuto 6-Ply Super Lug

  • Load Capacity: 1040 lb
  • Size: 18X9.50-8
  • Rim Size: 8 in

Best for: Deep-lug farm and garden traction.

Why it ranks #8: The 6-ply tire lists 16 mm tread depth and angled lug elements for pulling and pushing, but its aggressive tread is less turf-focused.

A 0.63-inch tread depth and sharp angled directional lugs give this MaxAuto 18×9.50-8 pair a clear focus on pulling and pushing traction. The 6-ply tubeless construction and stated 1320-pound maximum load further distinguish it for garden tractors, tillers, and trenchers where lugged tread is relevant.

The angled super-lug elements are described as providing pulling and pushing power, making the pattern relevant to traction-focused garden tractor, tiller, and trencher work. At 0.63 inches deep, the tread is substantially specified rather than left undescribed, and the 6PR/C construction is tubeless. MaxAuto lists a 7-inch rim width and 17.75-inch outer diameter for replacement checks. The feature section gives a 1320-pound maximum at 36 psi, while the specification table separately lists 1040 pounds, so capacity information conflicts.

Pros
  • Deep 0.63-inch directional lug tread
  • 6-ply tubeless construction
  • 7-inch rim width and 17.75-inch outer diameter listed
  • Angled lugs are described for pulling and pushing power
Cons
  • Load figures conflict: the feature section says 1320 pounds, while the specification table says 1040 pounds.

Skip it if you need an unambiguous 1040-pound load listing; MaxAuto 18×9.50-8 standard 4-ply tires state 1040 pounds at 24 psi.

This MaxAuto pair suits buyers seeking deep directional lugs for garden tractors, tillers, or trenchers. Its tread and dimensions are detailed, but the conflicting load figures require resolution before matching it to equipment.

HORSESHOE 6-Ply Super Lug

#9

9. HORSESHOE 6-Ply Super Lug

  • Load Capacity: 1320 lb
  • Size: 18×9.50-8 6PLY
  • Rim Size: 8 in

Best for: Six-ply trencher and farm lugs.

Why it ranks #9: This 6-ply herringbone super lug tire lists a 1320-pound capacity and suits farm or trencher applications more than general turf mowing.

A 6-ply Super Lug Herring Bone pattern and a listed 1320-pound capacity position this HORSESHOE 18×9.50-8 tire for buyers considering trencher, farm-tractor, or riding-mower applications. The listing also identifies tubeless construction, connecting its heavy-duty specification to a clear range of intended equipment.

HORSESHOE names a Super Lug Herring Bone tread and lists the tire for Ditch Witch trenchers, agricultural farm tractors, and riding lawn mowers, giving buyers a specific application context. Its 6-ply construction and 1320-pound load capacity are useful figures when checking equipment requirements. The 18×9.50-8 size and 8-inch rim specification support basic replacement screening. The listing identifies the tire as tubeless, but does not provide tread depth, pressure, or detailed mounting dimensions.

Pros
  • 6-ply construction
  • 1320-pound load capacity listed
  • Super Lug Herring Bone tread named
  • Tubeless 18×9.50-8 tire for listed farm, trencher, and mower applications
Cons
  • The supplied specifications do not give tread depth or tire pressure.

Skip it if you need a stated tread depth and inflation pressure; MaxAuto 18×9.50-8 Super Lug tires list both measurements.

This HORSESHOE tire suits buyers seeking a 6-ply, tubeless lug pattern for a listed trencher, farm tractor, or riding mower application. Check the 18×9.50-8 size and required operating details, which are not fully specified here.

MOTOOS ATV Knobby Tire

#10

10. MOTOOS ATV Knobby Tire

  • Load Capacity: 225 lb
  • Size: 18×9.50-8
  • Rim Size: 8 in

Best for: Directional-knobby ATV application.

Why it ranks #10: Although it matches the 18×9.50-8 size, this product is an ATV tire and lists a 225-pound capacity, making it the weakest lawn-mower fit.

A directional knobby tread identifies this MOTOOS 18×9.5-8 set as an ATV-oriented option rather than a conventional smooth or turf-focused mower tire. The supplied listing specifies two 4-ply tubeless tires and an 8-inch rim size, helping buyers distinguish its stated construction and application.

The 4-ply tubeless specification identifies the tire construction, and the directional knobby tread names the pattern for buyers considering an ATV setup. The 18×9.5-8 size and 8-inch rim designation provide the primary sizing details, while the two-tire package supports replacing a pair. MOTOOS lists a 225-pound load capacity, a key limit to check against the intended vehicle and use. No tread depth, pressure, or overall diameter is provided in the supplied specifications.

Pros
  • Directional knobby tread
  • 4-ply tubeless construction
  • Two tires included
  • 18×9.5-8 size with 8-inch rim listed
Cons
  • The listed load capacity is 225 pounds, limiting suitability where a higher rating is required.

Skip it if you need a 1040-pound-rated lawn-mower tire; MaxAuto 18×9.50-8 4-ply tires list that higher capacity.

Consider this pair for an ATV buyer whose application matches the directional knobby pattern and 225-pound listed capacity. The 8-inch rim and 18×9.5-8 sizing remain essential checks before choosing it for a specific vehicle.

Check the wheel before ordering

The printed tire size alone does not establish that a replacement fits your complete wheel assembly. Several products are tire-only or listed as tires, while the TRIBLE SIX Tire and Rim is described as including a rim; its listing also gives an unusual 16-inch overall diameter alongside an 18×9.50-8 size, so verify the dimensions before ordering. The Carlisle Smooth Tire listing explicitly says the rim is not included.

Confirm your existing rim diameter and width, hub or bolt pattern, and whether the tire is tubeless before choosing. The MaxAuto 4-Ply Lawn Tire and MOTOOS 4-Ply Lawn Tire each specify a 7-inch rim width, while many other listings only state an 8-inch rim size.

Do not assume an 8-inch rim size tells you the required rim width or wheel mounting pattern. Compare the equipment manual and current tire markings with the full listing, and contact the seller or equipment maker if a mounting detail is missing.

Match tread to the surface, not just the size

Tread style changes the tire’s intended use even when the size is identical. The MaxAuto 4-Ply Lawn Tire describes a pattern intended to increase ground friction while reducing noise, whereas the Carlisle Smooth Tire is specifically a smooth lawn-and-garden tire. The MaxAuto 6-Ply Super Lug and HORSESHOE 6-Ply Super Lug are markedly different: the former lists 16 mm tread depth and angled elements for pulling and pushing, and the latter is described as a super lug herringbone tire for farm and trencher applications.

More aggressive lugs may be appropriate when traction is the priority, but they are not simply interchangeable with a turf-style tread for routine lawn mowing. Consider the surfaces you actually cross and whether preserving turf or gaining grip matters more.

The product descriptions establish tread intent, not a guarantee of performance on your particular soil, slope, or wet grass.

How to Choose an 18×9.50-8 Tire

Load capacity and pressure

Choose a tire whose listed load capacity and pressure suit the equipment requirements; do not treat a higher number as permission to exceed the machine’s limits. The listed capacities span 225 pounds for the MOTOOS ATV Knobby Tire, 815 pounds for the MOTOOS 4-Ply Lawn Tire and TUFFIOM Turf Tire, and 1040 pounds for several lawn-tire options. The MaxAuto 4-Ply Lawn Tire gives a maximum of 1040 pounds at 24 psi, while its 6-ply Super Lug listing states 1320 pounds at 36 psi; its specifications section separately lists 1040 pounds, so verify the applicable rating with the seller before relying on it.

Buyers replacing a standard mower tire should use the equipment manual’s load and pressure guidance; heavier-duty applications should prioritize verified ratings for the exact tire.

Tread and ply construction

Choose tread and ply to suit the ground and work, rather than selecting by size alone. The MaxAuto 4-Ply Lawn Tire and MAXROLLORS Turf-S Tire are 4-ply options for lawn and garden equipment, while the MaxAuto 6-Ply Super Lug and HORSESHOE 6-Ply Super Lug offer deeper, more aggressive tread. The MaxAuto super lug lists 16 mm tread depth compared with 5 mm for the MaxAuto 4-ply tire.

Turf-oriented options suit buyers focused on routine lawn use; the listed lug tires target pulling, pushing, farm, or trencher applications. Carlisle also offers a smooth lawn-and-garden tire for buyers seeking that distinct tread style.

Ply count alone does not establish compatibility or performance, so check the machine’s requirements and confirm the specific tire’s load and pressure information.

Package contents and wheel fit

Confirm whether you need tires only or a tire-and-rim assembly, and compare the wheel dimensions with your equipment. The TRIBLE SIX Tire and Rim listing says its package includes tires with a rim and describes a 4-lug wheel, a 2.83-inch center bore, and a 4-inch PCD. By contrast, the Carlisle Smooth Tire explicitly excludes the rim, and the MaxAuto 4-Ply Lawn Tire is a set of two tires.

Several listings state an 8-inch rim size, but that does not by itself confirm the hub pattern or every fitment dimension. Buyers replacing rubber on existing wheels should verify tire width and rim requirements; buyers needing complete wheels should confirm bolt pattern, bore, and included hardware.

Do not assume a listed tire size makes the wheel assembly compatible.

Which 18×9.50-8 tire should I choose?

For a broadly useful, well-specified lawn and garden tire, choose the MaxAuto 4-Ply Lawn Tire: it lists tubeless construction, 1040-pound capacity at 24 psi, and 5 mm tread depth. The MAXROLLORS Turf-S Tire is another 1040-pound 4-ply option if its Turf-S designation suits your mower. If you need a wheel included, consider the TRIBLE SIX Tire and Rim, but verify its listed dimensions and mounting pattern against your equipment.

For more aggressive pulling or farm use, the MaxAuto 6-Ply Super Lug lists 16 mm tread depth; the HORSESHOE 6-Ply Super Lug is another farm-oriented choice. Choose the Carlisle Smooth Tire only when its smooth tread is specifically wanted, and avoid the MOTOOS ATV Knobby Tire for a mower unless the equipment maker confirms it is suitable.

Frequently Asked Questions

How can I confirm an 18×9.50-8 tire will fit my mower's existing rim and hub?

Confirm the size marked on your current tire, then compare the replacement’s listed dimensions and rim requirements with your mower manual or the equipment maker’s guidance. Also check wheel and hub mounting details; tire size alone does not confirm hub compatibility. For a tire-and-rim set, verify the rim dimensions and mounting pattern before ordering.

Should I choose a turf tread or a lug tread for my terrain?

Choose a turf-oriented tread for typical lawn use where limiting turf disturbance matters; consider angled, deeper lugs when pulling or working on rougher ground is the priority. The listed MaxAuto 6-ply Super Lug has 16 mm tread depth, while the MaxAuto 4-ply lawn tire is presented as a general-purpose option. Match tread to your equipment and terrain.

Can I replace just one tire, or should I replace both tires on the axle?

Replace both tires on an axle when the remaining tire is significantly worn, damaged, or mismatched in size or tread, unless your equipment maker advises otherwise. A single replacement may be suitable when the other tire is in comparable condition and the replacement matches. Check the mower manual for axle-specific guidance before deciding.

What should I check before inflating a tubeless replacement tire?

Use the pressure guidance for your specific tire and equipment rather than assuming all tires of this size share one inflation target. Check the tire’s markings and the mower manual, and make sure the tire is seated correctly before use. The listed MaxAuto 4-ply tire specifies a maximum load at 24 psi; that is not a universal setting.

When should I choose a tire that includes a rim?

Choose a tire-and-rim option when you need a wheel included, but verify its listed dimensions and mounting pattern against your equipment before ordering. A rim that appears to match the tire size may still not fit your hub. If you plan to reuse your existing rim, confirm that the replacement tire is compatible with it.

Final Words

For a broadly useful, well-specified lawn and garden tire, the MaxAuto 4-ply option leads, with listed tubeless construction, 1040-pound capacity at 24 psi, and 5 mm tread depth. The MAXROLLORS Turf-S is another 4-ply option. Choose a 6-ply super lug for more aggressive traction, and consider the TRIBLE SIX set if you need a rim—after checking fit.

Avoid the ATV knobby for mower use unless the equipment maker approves it.
