Best 8 Inch Trailer Tires for Utility and Boat Trailers

Best 8 Inch Trailer Tires

A strong 8-inch trailer tire choice matches your trailer’s tire size, wheel bolt pattern, and load needs; for many utility and boat trailers, a pre-mounted 4.80-8 set rated for 760 pounds per tire is a practical fit. These options include complete tire-and-wheel assemblies, tire-only replacements, and one larger 18.5×8.50-8 assembly, so “8 inch” alone does not guarantee compatibility. Our top pick, Garvee 4.80-8 Assemblies, combines a pair of mounted tires with a 4-lug, 4-on-4-inch bolt pattern and a stated 760-pound capacity per tire.

Before choosing, compare your existing tire size, hub pattern, center bore, and required load rating. The rankings distinguish ready-to-install wheel sets from tires that require compatible wheels.

Garvee 4.80-8 Assemblies leads this roundup because it includes two pre-mounted 4.80-8 tires, 8-inch rims, a 4-lug 4-on-4-inch pattern, and a stated 760-pound capacity per tire. It is a strong starting point for buyers replacing a matching utility or boat trailer setup. Confirm your trailer’s bolt pattern, center bore, tire clearance, and load requirements before ordering; a matching tire size alone does not ensure that the wheel fits your hub.

Detailed Reviews: Best 8 Inch Trailer Tires

Garvee 4.80-8 Assemblies

#1 · Best Overall

1. Garvee 4.80-8 Assemblies

  • Size: 4.80-8
  • Rim Size: 8 in
  • Weight: 19 lb

Best for: Pre-mounted utility trailer pair.

Why it ranks #1: A two-tire mounted set pairs 4.80-8 tires with 4-lug, 4-on-4-inch rims and a stated 760-pound capacity per tire.

Pre-mounted 4.80-8 tires on white 8-inch rims make this Garvee two-pack a ready-to-install option for compatible small trailers. The 4-lug, 4-inch bolt pattern and 2.85-inch center bore define its wheel fit, while each tire’s 760-pound rating supports utility, cargo, boat, or travel-trailer hauling.

The supplied 8-by-3.75-inch rims come already paired with the tires, so buyers can work with complete assemblies rather than separate tire and wheel components. A 4-lug, 4-inch bolt pattern and 2.85-inch center bore specify the fitment; check those dimensions against the trailer’s existing hubs. Each tire is rated for 760 pounds at up to 90 PSI, and the listed 16.3-inch overall diameter and 4.76-inch section width help identify the tire’s physical envelope for replacement planning.

Pros
  • Two 4.80-8 tire-and-rim assemblies
  • Pre-mounted tires on 8-by-3.75-inch rims
  • 4-lug, 4-inch pattern and 2.85-inch center bore
  • 760-pound tire capacity with 90 PSI maximum
Cons
  • The listed six-month warranty is shorter than the two-year coverage on eCustomRim’s TR1000-2 assemblies.

Skip it if you need the documented two-year coverage offered with eCustomRim TR1000-2 assemblies; this pair lists a six-month warranty.

Choose this Garvee pair for a compatible utility, cargo, boat, or travel trailer when pre-mounted wheels simplify replacement. Its fit depends on a 4-lug, 4-inch pattern and 2.85-inch center bore, and each tire is rated for 760 pounds.

GarveeTech 4.80-8 Assemblies

#2 · Best Reinforced Build

2. GarveeTech 4.80-8 Assemblies

  • Weight: 23.2 lb

Best for: Steel-belted boat trailer set.

Why it ranks #2: This pair includes Load Range C, 6PR tires rated 760 pounds at 90 PSI on 4-lug, 4-on-4-inch wheels.

Nylon cord layers and double steel belts distinguish this GarveeTech two-pack, with the construction specified to support towing stability and durability. Its 4.80-8 bias-ply tires are mounted on white 8-inch modular wheels, offering complete assemblies for compatible utility or boat trailers with a 4-lug, 4-inch pattern.

The tires are Load Range C, 6-ply rated, and each is listed for 760 pounds at 90 PSI, giving buyers defined capacity and inflation limits for trailer loading. Nylon cord layers and double steel belts are identified as construction features for towing stability and lasting performance. Because the tires arrive mounted on modular 8-inch wheels, the set avoids separate tire mounting; verify the 4-by-4-inch wheel pattern against the trailer hub before installation.

Pros
  • Two 4.80-8 bias-ply tire and wheel assemblies
  • Load Range C, 6-ply rating
  • 760-pound maximum load per tire at 90 PSI
  • Nylon cord layers and double steel belts
Cons
  • The supplied specifications do not state the wheel center-bore measurement.

Skip it if you require a listed center-bore dimension before ordering; Garvee’s B0GJ5K7397 set specifies a 2.85-inch bore.

This set suits utility and boat-trailer owners whose hubs match its 4-by-4-inch pattern and who want pre-mounted, steel-belted assemblies. Each tire’s stated capacity is 760 pounds at 90 PSI; the supplied details do not give a center-bore size.

Garvee 6PR Assemblies

#3 · Heat-Resistant Tread

3. Garvee 6PR Assemblies

  • Weight: 23.2 lb

Best for: Heat-conscious towing assemblies.

Why it ranks #3: The mounted 4.80-8, Load Range C set is rated 760 pounds and lists heat resistance and a high-tensile belt package.

A high-tensile belt package paired with an advanced tread gives this Garvee set a specific focus on puncture protection and heat resistance. The two 4.80-8 bias-ply tires arrive pre-mounted on white 8-inch rims, with Load Range C, 6-ply construction and a stated 760-pound capacity for utility, boat, or camper trailers.

Garvee identifies the advanced tread as promoting even wear and heat resistance, while the high-tensile belt package is specified for puncture protection—useful details for buyers weighing repeated towing demands. Steel-belted construction is also described as supporting towing stability and shock absorption. With tires pre-mounted on 8-inch rims, this two-pack provides wheel assemblies rather than loose tires; its listed 4-lug, 4-inch pattern and 760-pound rating help guide hub-fit and load checks.

Pros
  • Two pre-mounted 4.80-8 tire and wheel assemblies
  • Load Range C, 6-ply construction
  • Advanced tread specified for even wear and heat resistance
  • High-tensile belt package for puncture protection
Cons
  • The supplied specifications do not state a maximum inflation pressure.

Skip it if you need a stated pressure limit for setup; Garvee’s B0GJ5K7397 lists a 90 PSI maximum for each tire.

This Garvee pair fits buyers seeking pre-mounted assemblies with specified heat-resistance and puncture-protection features for utility, boat, or camper towing. Check the listed 4-lug, 4-inch pattern and 760-pound capacity; pressure guidance is not included in the supplied specifications.

eCustomRim 4.80-8 Assemblies

#4 · Longest Warranty

4. eCustomRim 4.80-8 Assemblies

  • Size: 4.80-8
  • Rim Size: 8 in
  • Weight: 20 lb

Best for: Lower-pressure replacement pair.

Why it ranks #4: This pair has 4.80-8 Load Range C tires, 4-lug 4-on-4-inch wheels, and a listed two-year manufacturer warranty.

A 60 PSI maximum sets this eCustomRim 4.80-8 pair apart from many listed assemblies, making its inflation ceiling a clear selection point. The bias-ply tires are rated for 760 pounds and come with 8-by-3.75-inch rims, a 2.83-inch center bore, and a 4-lug, 4-inch bolt pattern.

The stated 16.5-inch overall diameter and 760-pound rating help buyers assess replacement dimensions and load capacity, while the 60 PSI maximum gives a specific pressure limit to observe. Each assembly uses an 8-by-3.75-inch alloy-steel rim with a 2.83-inch center bore and 4-lug, 4-inch pattern. Those measurements make hub and clearance checks concrete before installation, and the supplied two-year warranty is a relevant ownership detail for the pair.

Pros
  • Two bias-ply 4.80-8 assemblies
  • 760-pound tire rating with 60 PSI maximum
  • 8-by-3.75-inch alloy-steel rims
  • 2.83-inch center bore and 4-lug, 4-inch pattern
Cons
  • The 60 PSI maximum is lower than the 90 PSI rating listed for Garvee’s B0GJ5K7397 tires.

Skip it if you need a 90 PSI maximum; Garvee B0GJ5K7397 lists that pressure limit for its 4.80-8 assemblies.

Consider this pair if its 60 PSI ceiling, 760-pound rating, and measured rim fit suit your trailer. The 2.83-inch bore and 4-lug, 4-inch pattern are specific fit considerations, and its listed two-year warranty may matter for ownership planning.

#5

5. GarveeTech 480-8 Assemblies

  • Size: 480-8
  • Rim Size: 8 in
  • Weight: 21 lb

Best for: Direct-fit four-lug replacements.

Why it ranks #5: A ready-to-mount two-pack offers 6PR tires rated 760 pounds each, with 4-on-4-inch bolt pattern and 2.85-inch center bore.

A 2.85-inch center bore and 4-lug, 4-inch bolt pattern give this GarveeTech two-pack defined fit dimensions for compatible utility and cargo trailers. The 4.80-8 tires arrive on 8-by-3.75-inch rims, with Load Range C, 6-ply construction and a 760-pound capacity per tire for hauling applications.

The stated 16.29-inch overall diameter and 4.76-inch section width help buyers compare the assembly’s dimensions with their existing trailer setup. Its 2.85-inch center bore and 4-by-4-inch bolt pattern provide concrete hub-fit checks, while pre-mounted 8-by-3.75-inch rims simplify replacing tire-and-wheel assemblies. Each tire is rated for 760 pounds at a maximum 90 PSI, so buyers can assess load and inflation limits alongside the listed fitment.

Pros
  • Two mounted 4.80-8 tire and wheel assemblies
  • 4-lug, 4-inch pattern and 2.85-inch center bore
  • 760-pound capacity per tire with 90 PSI maximum
  • Load Range C, 6-ply construction
Cons
  • The listed 60-day warranty is shorter than the six-month warranty on Garvee’s B0GJ5K7397 pair.

Skip it if you want a longer listed warranty; Garvee B0GJ5K7397 states six months, compared with this pair’s 60 days.

Pick this GarveeTech set when your trailer uses the specified four-lug pattern and center bore and you want complete replacement assemblies. Its dimensions and 760-pound-per-tire rating support fit and load checks; the listed warranty is 60 days.

MERXENG 4.80-8 Assemblies

#6 · Black Wheel Option

6. MERXENG 4.80-8 Assemblies

  • Size: 4.80-8
  • Rim Size: 15 in
  • Weight: 23.2 lb

Best for: Black-rim trailer replacement pair.

Why it ranks #6: This pair of 4.80-8, 6PR tires includes black 4-lug wheels and a stated 760-pound capacity per tire at 90 PSI.

Black 8-inch rims give this MERXENG two-pack a distinctive complete-assembly option for compatible utility, boat, camper, or cargo trailers. The 4.80-8 bias-ply tires are Load Range C, 6-ply rated, and specified for 760 pounds per tire at 90 PSI, with a 4-lug, 4-inch bolt pattern.

Because the tires are supplied with rims, buyers can consider them as replacement assemblies rather than sourcing wheels separately. The stated 4-lug, 4-inch pattern defines the hub connection to check before installation, while the 6-ply Load Range C construction and 90 PSI maximum provide load and inflation details. MERXENG lists broad trailer applications, including utility, boat, camper, and cargo use; confirm that the stated 760-pound tire capacity suits the intended load.

Pros
  • Two 4.80-8 tire-and-rim assemblies
  • Black 8-inch rims
  • Load Range C, 6-ply construction
  • 760-pound capacity per tire at 90 PSI
Cons
  • The supplied specifications report a 15-inch rim size, which conflicts with the title’s 8-inch rim description.

Skip it if you require consistent rim-size details before buying; GarveeTech B0GDXZDC5W lists 8-by-3.75-inch rims and a 2.85-inch center bore.

This MERXENG set may suit trailer owners seeking two black-rim assemblies for utility, boat, camper, or cargo use. Its stated 4-lug pattern and tire rating aid selection, but the listing conflicts on rim size, so resolve that discrepancy before ordering.

Kenda K371 Tires

#7

7. Kenda K371 Tires

  • Size: 4.80/4.00-8 2 Pack
  • Rim Size: 8 in
  • Weight: 10.4 lb

Best for: Tread-focused utility tires.

Why it ranks #7: These two 4.80/4.00-8 bias-ply tires suit buyers reusing wheels; the listed load capacity is 590 pounds.

Kenda’s computer-optimized tread combines a radial-like appearance with bias-ply durability, giving this 4.80/4.00-8 pair a specific traction and construction profile. The flatter tread profile is identified as improving towing stability and control, while the listed 590-pound capacity per tire helps buyers judge its load suitability.

The flatter tread profile is described as reducing sway and improving control, a practical consideration for utility, cargo, and boat-trailer towing. Kenda also lists a durable rubber compound for longer tread life and low rolling resistance, linking the material choice to wear and operating efficiency. These are tires only, not wheel assemblies, so buyers must supply compatible rims and handle mounting separately; the 590-pound capacity per tire is an important load boundary.

Pros
  • Two Kenda K371 bias-ply tires
  • Computer-optimized tread pattern
  • Flatter profile specified to improve stability and control
  • Rubber compound described for longer tread life and low rolling resistance
Cons
  • These are tires only, and the 590-pound capacity per tire is lower than the 760-pound rating of GarveeTech B0GZZS3VPN.

Skip it if you need wheels included or a 760-pound tire rating; GarveeTech B0GZZS3VPN lists that capacity and supplies mounted assemblies.

This Kenda pair suits owners prioritizing its tread profile and rubber-compound features for utility, cargo, or boat trailers. It is a tire-only purchase, and each tire’s listed 590-pound capacity makes load calculation essential before use.

Carlisle Sport Trail

#8

8. Carlisle Sport Trail

  • Size: 4.80-8 C
  • Rim Size: 8 in
  • Weight: 6 lb

Best for: Tire-only heat-management choice.

Why it ranks #8: This 4.80-8 bias-ply tire fits the target size and is designed for utility, boat, horse, stock, and cargo trailers; it is tire-only.

A tread and contour specified to reduce heat build-up distinguish the Carlisle Sport Trail, a bias-ply 4.80-8 tire for towable utility, boat, horse, stock, and cargo trailers. Its specialty-trailer application is explicit, and the tire-only format suits buyers who already have compatible wheels.

Carlisle identifies the tread and contour as helping reduce heat build-up and support endurance, a relevant consideration for trailer operation. The bias-ply construction is described as offering radial-like capabilities, while the rugged sidewall protects against curbing and other damage. This is a tire-only listing rather than a mounted assembly, so installation requires a compatible wheel. Its 4.80-8 C size is specified for trailer use and is not approved for passenger vehicles.

Pros
  • 4.80-8 C bias-ply trailer tire
  • Tread and contour specified to reduce heat build-up
  • Rugged sidewall protects against curbing and other damage
  • Listed for utility, boat, horse, stock, and cargo trailers
Cons
  • This listing is tire only, so a compatible wheel is not included.

Skip it if you need a complete mounted assembly; MERXENG B0GGHCDFLX lists a pair of 4.80-8 tires with rims.

Choose the Carlisle Sport Trail if you need a single 4.80-8 tire for a compatible towable trailer and value its heat-management tread and rugged sidewall. It is not a passenger-vehicle tire, and the listing does not include a wheel.

Triton 18.5x8.50-8 Assemblies

#9

9. Triton 18.5×8.50-8 Assemblies

  • Size: 18.5X8.50-8
  • Rim Size: 8 in
  • Weight: 34 lb

Best for: Triton watercraft trailer pair.

Why it ranks #9: A pair of 18.5×8.50-8 assemblies has a stated 935-pound capacity, but its 5-on-4.5-inch pattern is a more specific fit.

A 935-pound load capacity and 5-on-4.5 bolt pattern make this Triton pair a distinct option for compatible watercraft, snowmobile, and utility trailers. These 18.5-by-8.50-8 assemblies use silver powder-coated rims and a tubeless tire construction, so the wheel pattern is central to confirming a match.

The listed 18.5-by-8.50-8 size, also identified as 215/60-8, gives a specific tire designation for replacement planning, while the 8-inch rim size defines the wheel class. A standard 5-on-4.5 bolt pattern is described as common on Triton personal watercraft and snowmobile trailers, making hub measurement especially important. Sold as a pair, the assemblies include silver powder-coated rims, and their tubeless construction is another relevant setup detail for compatible trailers.

Pros
  • Pair of trailer tire-and-wheel assemblies
  • 935-pound listed load capacity
  • 5-on-4.5 bolt pattern
  • Tubeless tires with silver powder-coated rims
Cons
  • The supplied details identify a 5-lug pattern, not the 4-lug fit used by the other listed 4.80-8 options.

Skip it if you need a 4-lug wheel; Carlisle Sport Trail 4.80-8 is listed as a tire-only option for compatible trailer wheels.

Choose the Triton pair for a compatible watercraft, snowmobile, or utility trailer that uses its 5-on-4.5 pattern. Its 18.5-by-8.50-8 size and 935-pound capacity help identify the application, but it is not the listed 4-lug style.

Hi-Run SU02 ST5.7-8

#10

10. Hi-Run SU02 ST5.7-8

  • Size: 5.7-8
  • Rim Size: 8 in
  • Weight: 10 lb

Best for: Higher-capacity tire-only option.

Why it ranks #10: This tire-only 5.7-8 option lists a 1,074-pound capacity, but its tire size differs from the common 4.80-8 choices in this roundup.

An 8-ply rating and listed 1,074-pound load capacity distinguish the Hi-Run SU02 from the 4.80-8 options in this roundup. This is an ST5.7-8, all-season bias tire with an 83M D specification, supplied as a tire only for buyers who have a compatible 8-inch wheel.

The 1,074-pound listed capacity and 8-ply designation give buyers concrete load-related specifications to evaluate for a trailer application. Its ST5.7-8 size differs from the 4.80-8 sizes elsewhere in this group, so size and wheel compatibility need particular attention before replacement. The all-season bias construction is specified, and the tire-only format means the wheel is not included in the supplied components; plan for a compatible rim and mounting separately.

Pros
  • 1,074-pound listed load capacity
  • 8-ply rating
  • All-season bias tire
  • Tire-only format for owners sourcing a separate wheel
Cons
  • The ST5.7-8 size is not the 4.80-8 size specified by the roundup’s main tire category.

Skip it if you need a 4.80-8 tire; Kenda K371 B081S1Y3SS lists 4.80/4.00-8 tires, though wheels are not included.

Consider the Hi-Run if its ST5.7-8 size matches your trailer and its listed capacity suits the intended load. It is a tire-only purchase, not a mounted assembly, so confirm wheel compatibility and account for separate mounting.

Avoid the bolt-pattern and center-bore mismatch

A tire size match does not guarantee that a mounted wheel will fit your trailer hub. Several 4.80-8 assemblies here use a 4-lug pattern on a 4-inch bolt circle, but their center bores differ: Garvee 4.80-8 Assemblies lists 2.85 inches, while eCustomRim 4.80-8 Assemblies lists 2.83 inches. GarveeTech 480-8 Assemblies also lists a 2.85-inch center bore.

The Triton 18.5×8.50-8 Assemblies instead uses a 5-on-4.5-inch bolt pattern, so it is not a direct substitute for a 4-lug wheel. Check the existing wheel markings and measure the hub and bolt pattern before ordering.

Also compare rim width and clearance where available; the Garvee listings specify 8-by-3.75-inch rims. If a key measurement is missing from a listing, verify it with the seller rather than assuming it matches.

Why load capacity must be checked per tire

The capacity number matters only when it is understood in the context of the trailer’s total load and the number of tires carrying it. Several 4.80-8 assemblies list 760 pounds per tire, including Garvee 4.80-8 Assemblies and GarveeTech 4.80-8 Assemblies; Kenda K371 Tires lists 590 pounds. The Triton 18.5×8.50-8 Assemblies lists 935 pounds, while the Hi-Run SU02 ST5.7-8 lists 1,074 pounds but is a different tire size and tire-only product.

Do not select by the largest number alone: size, wheel fit, tire pressure, and the trailer maker’s load requirements still govern. A listing’s capacity may also be presented inconsistently; MERXENG 4.80-8 Assemblies gives a 760-pound per-tire claim in its features but a different load-capacity figure in specifications.

Resolve discrepancies and confirm the intended rating before purchase.

Start by matching the size printed on your existing tire and the clearance available around the wheel. Most assemblies here use 4.80-8, while Kenda K371 Tires is marked 4.80/4.00-8; Triton 18.5×8.50-8 Assemblies and Hi-Run SU02 ST5.7-8 use distinct sizes. The 4.80-8 options suit a buyer replacing that same size, but they are not automatically interchangeable with every tire mounted on an 8-inch rim.

A buyer replacing a specific Triton personal-watercraft setup may prefer its 18.5×8.50-8 assembly, while someone replacing a 5.7-8 tire should prioritize the Hi-Run size and verify wheel compatibility.

Load rating and pressure

Choose a tire whose listed capacity and pressure meet the trailer’s requirements, and do not treat the highest figure as a universal upgrade. Several 4.80-8 mounted sets state 760 pounds per tire and 90 PSI, while eCustomRim 4.80-8 Assemblies lists 760 pounds and a maximum 60 PSI. Kenda K371 Tires lists 590 pounds; Triton 18.5×8.50-8 Assemblies lists 935 pounds, and Hi-Run SU02 ST5.7-8 lists 1,074 pounds.

Buyers needing a 4.80-8 replacement should compare the rating of the exact option with their trailer specifications. Higher listed capacity may suit a different size or setup, not necessarily your existing wheel and tire combination.

Mounted assembly or tire only

Decide whether you need a complete wheel assembly or just replacement tires. Garvee 4.80-8 Assemblies, GarveeTech 4.80-8 Assemblies, and eCustomRim 4.80-8 Assemblies include mounted tires and wheels; Kenda K371 Tires and Carlisle Sport Trail are tire-only options. A complete set makes sense when your current wheels are damaged or the bolt pattern needs replacing, provided the new pattern and center bore match.

Tire-only choices favour buyers whose existing wheels are compatible and reusable. Check each listing’s supplied components: the product descriptions identify tire-and-wheel sets for several options, while Carlisle Sport Trail explicitly lists a tire as the included component.

Which 8-Inch Trailer Tires Should You Choose?

For a common 4.80-8 replacement where you need wheels included, choose Garvee 4.80-8 Assemblies: it provides two mounted tires, a 4-on-4-inch pattern, and a stated 760-pound capacity per tire. If you want another 6PR mounted set, GarveeTech 4.80-8 Assemblies also lists 760 pounds per tire and 90 PSI. For buyers reusing compatible wheels, Kenda K371 Tires supplies two tire-only replacements, while Carlisle Sport Trail is a single tire-only choice.

Choose Triton 18.5×8.50-8 Assemblies only when that larger tire size and its 5-on-4.5-inch wheel pattern match your trailer. The Hi-Run SU02 ST5.7-8 is a different tire size, so do not substitute it for 4.80-8 without confirming fitment.

Frequently Asked Questions

How do I measure a trailer wheel’s bolt pattern and center bore?

Count the wheel’s lug holes, then measure the bolt pattern using the distance between the centers of the appropriate lug holes; the method depends on the number of lugs. Measure the center bore across the opening in the wheel. Compare both measurements with your trailer’s hub or its documentation, and confirm fitment before ordering.

Should trailer tires be replaced in pairs or as a full set?

Replace tires in pairs on the same axle when one is worn or damaged, and consider a full set when tires across the trailer are similarly aged or worn. Keep tire size, construction, and load capacity appropriate for the trailer. Check the trailer and tire guidance before deciding, since replacing only one may leave mismatched tires.

How often should trailer tires be inspected and replaced?

Inspect trailer tires before trips and periodically while the trailer is in use; replace them when damage, significant wear, or other unsafe conditions appear. Check tread and sidewalls, and verify inflation against the tire or trailer guidance. Do not rely on appearance alone: consult the tire maker’s replacement guidance for age-related limits.

How can I tell whether I need a tire-and-wheel assembly or a tire-only replacement?

Choose a tire-and-wheel assembly if you need a wheel included or cannot reuse your existing wheel; choose tire-only replacements when your wheels are compatible and suitable for reuse. Confirm the replacement tire size and wheel fitment against your trailer. This roundup includes both assembly options and tire-only choices, so check each listing’s contents.

What should I verify before choosing a different tire size?

Confirm the trailer’s required tire size, load requirements, available clearance, and wheel fitment before choosing a different size. A matching wheel diameter alone does not establish compatibility. For example, the listed 18.5×8.50-8 and ST5.7-8 options are different sizes from 4.80-8; do not substitute them without confirming fitment.

Final Words

For a common 4.80-8 replacement that needs wheels included, Garvee 4.80-8 Assemblies is the leading pick in this roundup, with two mounted tires, a 4-on-4-inch pattern, and a stated 760-pound capacity per tire. Consider the tire-only options if reusing compatible wheels. Before ordering, verify bolt pattern, center bore, clearance, tire size, and load requirements; choose the Triton or Hi-Run only if its different size fits.
