A strong 12-inch trailer tire choice pairs the correct tire size and load capacity with a wheel that matches your trailer’s bolt pattern, making these options useful for compatible utility, boat, and cargo trailers. The eCustomRim White 4.80-12 Assembly leads because it combines Load Range C tires rated for 990 pounds each with 12-by-4-inch rims and a 5-lug-on-4.5-inch pattern. This roundup includes mounted two-tire sets, tire-only options, a 5.30-12 alternative, and a 4-lug assembly, so the listings are not interchangeable.
Check your existing tire size, wheel bolt pattern, and trailer’s required load before choosing. The stated load rating applies per tire where specified; confirm that the complete setup suits the trailer and its intended load.
The eCustomRim White 4.80-12 Assembly is the best overall choice in this group for buyers whose trailer takes a 5-lug-on-4.5-inch wheel. It includes two mounted 4.80-12 Load Range C tires rated for 990 pounds each, with 12-by-4-inch rims, a 2.95-inch center bore, and a stated 60 PSI maximum. Its two-year warranty is also listed.
Verify your trailer’s bolt pattern and pressure requirements before ordering, since similarly sized 12-inch assemblies here include different wheel patterns and pressure specifications.

Detailed Reviews: Best 12 Trailer Tire

#1 · Best Overall
1. eCustomRim White 4.80-12 Assembly
- Size: 4.80-12
- Weight: 36 lb
- Rim Size: 12 in
Best for: White Five-Lug Assembly Pair.
Why it ranks #1: Two mounted Load Range C tires rated at 990 pounds each come on 12-by-4-inch rims with a 5-on-4.5-inch pattern and two-year warranty.
A 5-on-4.5-inch bolt pattern and 2.95-inch center bore give this white eCustomRim pair concrete mounting dimensions for compatible trailer hubs. Each 4.80-12 bias-ply tire is rated for 990 pounds, and the two rims arrive as part of the assembly.
The 12-by-4-inch rims, five-lug 4.5-inch pattern, and 2.95-inch center bore let buyers check hub compatibility before arranging a wheel change. Each Load Range C tire has a 990-pound rating and 60 PSI maximum, clarifying its stated load and pressure limits. A 20.5-inch overall diameter offers another useful clearance reference. Because this is a two-piece tire-and-rim assembly set, it can address both sides of a trailer together when dimensions match.
- Two tire-and-rim assemblies
- 990-pound maximum load per tire
- 5-on-4.5-inch bolt pattern and 2.95-inch center bore
- 12-by-4-inch rims with 20.5-inch tire diameter
- 60 PSI maximum is lower than Garvee's 90 PSI 4.80-12 pair.
Skip it if you require a 90 PSI maximum; Garvee's 1120642 4.80-12 pair lists that pressure limit.
A useful option for compatible utility, boat, or equipment trailers using the listed five-lug pattern. Check the 990-pound rating, 60 PSI maximum, center bore, and overall diameter against the trailer and hub requirements.

#2 · Black Rim Option
2. eCustomRim Black 4.80-12 Assembly
- Size: 4.80-12
- Weight: 36 lb
- Rim Size: 12 in
Best for: Black 5-Lug Assembly Pair.
Why it ranks #2: This two-tire Load Range C assembly matches a 5-on-4.5-inch pattern, carries 990 pounds per tire, and has black 12-inch rims.
A pre-mounted 4.80-12 tire and black 12-by-4-inch rim pair combines a 990-pound-per-tire rating with a 5-on-4.5-inch bolt pattern. That setup can simplify replacing compatible trailer wheels while keeping the load rating and key mounting dimensions together in one assembly.
Each bias-ply tire is rated for 990 pounds and 60 PSI, giving buyers clear load and inflation limits to work with. The 12-by-4-inch rim has a 2.95-inch center bore and a 5-on-4.5-inch bolt pattern, so those dimensions help identify compatible five-lug trailer hubs before installation. A stated 20.5-inch overall diameter also helps with checking wheel clearance. This is an assembly pair, rather than a tire-only purchase, for replacing both sides together.
- Two tire-and-rim assemblies included
- 990-pound maximum load per tire
- 12-by-4-inch rim with 5-on-4.5-inch pattern
- 20.5-inch overall tire diameter
- 60 PSI maximum is lower than the 90 PSI specification on the Garvee 4.80-12 pair.
Skip it if you need pressure capacity above 60 PSI; Garvee's 4.80-12 pair lists a 90 PSI maximum.
A practical match for a compatible utility or other trailer needing two black 4.80-12 wheel assemblies. Check the five-lug, 4.5-inch bolt pattern, center bore, load needs, and 60 PSI limit against your setup.

#3 · 90 PSI Option
3. GarveeTech 4.80-12 Assembly
- Size: 4.80-12
- Weight: 39.7 lb
- Rim Size: 12 in
Best for: Reinforced-Cord Trailer Pair.
Why it ranks #3: The pair includes mounted Load Range C, 6-ply tires rated for 990 pounds at 90 PSI on white 12-inch wheels with a 5-on-4.5-inch pattern.
Nylon cord layers and double steel belts distinguish this pair of 4.80-12 bias-ply trailer tires, supporting the maker's stated focus on towing stability. The tires arrive mounted on white 12-inch spoke wheels, making the set a ready wheel-pair option for compatible five-lug trailers.
Each tire has Load Range C, 6-ply construction, and a maximum load of 990 pounds at 90 PSI; those figures let buyers compare the assembly with their trailer's load and pressure needs. The 5-on-4.5-inch PCD identifies its five-lug mounting pattern, while the 12-inch wheels provide a concrete wheel-size reference. Nylon cords and double steel belts are specified as construction features, and the package includes two tire-wheel assemblies for a paired replacement.
- Nylon cord layers and double steel belts
- Load Range C, 6-ply construction
- 990-pound maximum load at 90 PSI per tire
- Two assemblies on white 12-inch spoke wheels
- No manufacturer warranty is listed.
Skip it if you need a stated manufacturer warranty; eCustomRim's 39343-2 assembly lists a two-year warranty.
A fit to consider for utility, boat, camper, travel, farm, or hauling trailers that use the listed five-lug pattern. Match the load, pressure, and wheel dimensions to your trailer before choosing this white-wheel pair.

#4 · Highest Capacity
4. Garvee 5.30-12 Assembly
- Size: 5.30-12
- Weight: 44.1 lb
- Rim Size: 12 in
Best for: Higher-Capacity 5.30-12 Pair.
Why it ranks #4: For buyers needing the listed larger tire size, this two-piece set supports 1,050 pounds at 80 PSI and includes black 12-inch rims.
A 1,050-pound load rating per tire gives this 5.30-12 pair a higher stated capacity than the supplied 4.80-12 alternatives. The two tires come with black 12-by-4-inch steel rims, offering a combined replacement option for compatible utility, boat, camper, or cargo trailers.
The 6-ply construction and Load Range C designation accompany the 1,050-pound rating, with a specified maximum pressure of 80 PSI; buyers can use those figures to assess the intended load and inflation requirements. The 5.30-12 size differs from 4.80-12 options, so tire size is a key compatibility check. Each black steel rim measures 12 by 4 inches and has a 5-on-4.5-inch bolt pattern, supporting a direct review of wheel fit before installation.
- 1,050-pound maximum load per tire
- 5.30-12 tire size
- 6-ply, Load Range C construction
- Two black 12-by-4-inch steel rims included
- The 5.30-12 size is not interchangeable with 4.80-12 tires without matching trailer requirements.
Skip it if you need 4.80-12 tires; the eCustomRim 39343-2 assembly uses that size and a five-lug pattern.
This pair suits buyers whose utility, boat, camper, or cargo trailer calls for 5.30-12 tires and the listed five-lug mounting pattern. Confirm the larger tire size, load needs, and 80 PSI limit work for your trailer.

5. Garvee 4.80-12 Assembly
- Size: 4.80-12
- Weight: 39.9 lb
- Rim Size: 12 in
Best for: Higher-Pressure 4.80-12 Pair.
Why it ranks #5: This two-tire 4.80-12 set comes mounted on white 12-by-4-inch rims with a 5-on-4.5-inch pattern and a stated 990-pound capacity per tire.
A 90 PSI maximum pairs with a 990-pound-per-tire rating in this two-piece 4.80-12 tire-and-rim set. Its 12-by-4-inch white rims arrive with the tires mounted, letting owners of compatible five-lug trailers replace a pair without sourcing rims separately.
The listed 5-on-4.5-inch bolt pattern and 2.95-inch center bore give concrete dimensions to check against the trailer hubs before fitting. Each tire supports up to 990 pounds, with a maximum 90 PSI, so buyers can evaluate those limits against their trailer requirements. The 20.6-inch overall diameter and 4.8-inch section width are useful clearance and sizing references. With two tires already on 12-inch rims, the set consolidates the parts for a paired wheel change.
- Two tires supplied mounted on rims
- 990-pound maximum load per tire
- 90 PSI maximum pressure
- 5-on-4.5-inch bolt pattern and 2.95-inch center bore
- The listed manufacturer warranty is three months.
Skip it if you want nylon cord layers and double steel belts specifically; GARVEETECH's R74G_679 lists both.
Consider this pair for cargo, utility, boat, or travel trailers when the 4.80-12 size and five-lug pattern match. Its 90 PSI limit and 990-pound rating are useful selection checks, not substitutes for verifying trailer requirements.

View on AmazonWhy it ranks #6: The tire-only pair is listed with Load Capacity of 990 pounds and 6-ply Load Range C construction, but wheel fitment details are not provided.
The 6-ply, Load Range C specification makes this WANDA 4.80-12 set a clearly identified option for buyers comparing trailer tire construction. Listed for highway, boat, and motorcycle trailer use, the two-tire set has a 990-pound load capacity and a 12-inch rim size.
The 4.80-12 size and 12-inch rim specification provide core sizing references for a replacement decision, while the 990-pound load capacity helps buyers compare the tires with trailer requirements. Its 6-ply, Load Range C title details the stated construction class. The listing identifies the product as a set of two tires but provides no rim assembly dimensions, so buyers seeking mounted wheels will need to account for that distinction when planning installation.
- Set of two tires
- 4.80-12 size
- 6-ply, Load Range C specification
- 990-pound listed load capacity
- The listing identifies tires, not mounted rim assemblies.
Skip it if you want assembled wheels included; eCustomRim's 39343-2 4.80-12 pair lists tires with rims.
A reasonable candidate for buyers comparing 4.80-12 tires for highway, boat, or motorcycle trailers, provided the 990-pound capacity meets requirements. The listing does not specify assembled rims, so plan accordingly for installation.

7. AutoSteelix 4.80-12 Tires
- Size: 4.80-12
- Weight: 17.9 lb
- Rim Size: 12 in
Best for: AutoSteelix Load Range C Pair.
Why it ranks #7: This two-pack is listed as 6-ply Load Range C with a 990-pound load capacity; the supplied specifications do not identify a rim pattern.
This two-pack of 4.80-12 trailer tires pairs a 6-ply, Load Range C specification with a listed 990-pound load capacity. Its 12-inch rim size offers a straightforward sizing reference for buyers replacing tires on a compatible utility trailer setup.
The 4.80-12 tire size and 12-inch rim size help narrow down replacement compatibility, while the stated 990-pound load capacity lets buyers compare against trailer demands. The title specifies 6-ply Load Range C, giving a construction category to assess alongside the load figure. The included-components field says two wheels, but the listing does not provide a bolt pattern or detailed assembly dimensions; check the wheel setup carefully before installation rather than assuming hub compatibility.
- Two included wheels
- 4.80-12 tire size
- 6-ply, Load Range C specification
- 990-pound listed load capacity
- No bolt pattern or center-bore dimensions are listed.
Skip it if you need a specified five-lug pattern; eCustomRim's 39343-2 assembly lists a 5-on-4.5-inch pattern.
This pair merits consideration for a utility trailer when its 4.80-12 size and listed capacity suit the application. The missing bolt-pattern details make wheel-hub compatibility an essential check before ordering or installing.

#8 · 4-Lug Fit
8. eCustomRim 4-Lug Assembly
- Size: 4.80-12
- Weight: 36 lb
- Rim Size: 12 in
Best for: Four-Lug 4.80-12 Assembly.
Why it ranks #8: It offers two mounted 4.80-12 Load Range C tires rated at 990 pounds each, but its 4-on-4-inch pattern fits fewer setups than the 5-lug options.
A four-lug, 4-on-4-inch bolt pattern makes this 4.80-12 eCustomRim assembly a distinct fit from the five-lug options. The two white wheel-and-tire assemblies arrive together, with each Load Range C bias-ply tire rated for 990 pounds and 90 PSI maximum.
Each assembly uses a 12-by-4-inch steel rim with a 2.83-inch center bore and the specified four-lug, 4-on-4-inch pattern, giving buyers key dimensions for checking compatible trailer hubs. The tire's 990-pound rating, 90 PSI maximum, and 20.5-inch diameter help evaluate load, inflation, and clearance. The listing states that the DOT-approved tire, wheel, and valve stem come assembled, reducing separate component handling during a compatible wheel replacement.
- Two assembled tire, wheel, and valve-stem units
- Four-lug 4-on-4-inch bolt pattern
- 990-pound maximum load per tire
- 90 PSI maximum and 20.5-inch diameter
- The four-lug pattern will not fit hubs requiring a five-lug wheel.
Skip it if you need five-lug wheels; eCustomRim's 39343-2 assembly uses a 5-on-4.5-inch pattern.
This assembly fits buyers replacing wheels on compatible utility or cargo trailers with the listed four-lug setup. Verify the 4-on-4-inch pattern, center bore, load rating, and available clearance before installation.

9. eCustomRim Load B Tires
- Size: 4.80-12
- Weight: 24 lb
- Rim Size: 12 in
Best for: Lower-Load Tire-Only Pair.
Why it ranks #9: These two 4.80-12 bias-ply tires have a 20.5-inch diameter and two-year warranty, but Load Range B is rated at 785 pounds each.
A 785-pound rating per tire and Load Range B set this 4.80-12 pair apart from the higher-rated Load Range C options. The package contains two bias-ply tires, so it suits buyers replacing tires while retaining compatible existing wheels rather than seeking complete wheel assemblies.
The stated 20.5-inch overall diameter and 60 PSI maximum provide useful references for clearance and inflation planning. Load Range B and the 785-pound rating clarify the pair's capacity, helping buyers compare it with their trailer's requirements before mounting. These are tires, not complete rim assemblies, so owners need compatible 12-inch rims available for installation. The listing also notes steel-wheel construction facts, but does not specify a rim included with this two-tire set.
- Two 4.80-12 bias-ply tires
- Load Range B construction
- 785-pound maximum load per tire
- 20.5-inch overall diameter and 60 PSI maximum
- Tires are supplied without rims, so installation requires compatible existing or separately sourced wheels.
Skip it if you need mounted rims included; eCustomRim's 39343-2 4.80-12 assembly includes the tire-and-rim combination.
Choose this pair when existing compatible 12-inch wheels are ready and the trailer's load requirements suit 785 pounds per tire. It is not a complete wheel assembly, so plan for mounting on rims separately.

10. Forerunner QH502 Tire
- Size: 4.8-12
- Weight: 9 lb
- Rim Size: 12 in
Best for: Tire-Only Forerunner Option.
Why it ranks #10: This 4.8-12 tire is listed as a 6-ply bias tire with 990-pound capacity, but it is tire-only and provides no wheel fitment details.
A 9-pound listed item weight makes this Forerunner QH502 a notably specified tire-only option for buyers managing a single replacement. It is a 4.8-12 all-season bias tire with 6-ply construction and a 990-pound load capacity, but no wheel is included.
The 4.8-12 size and 12-inch rim reference help buyers compare it with an existing wheel, while the 990-pound capacity provides a load figure to match against trailer needs. Its all-season designation and 6-ply construction are stated in the title, identifying the tire type and ply specification. Since the included-components field says tire only, this is a replacement-tire purchase rather than a mounted assembly; a compatible rim is needed for installation.
- 4.8-12 all-season bias tire
- 6-ply construction
- 990-pound listed load capacity
- Tire-only listing with 9-pound item weight
- No rim is included, so it cannot replace a complete wheel assembly by itself.
Skip it if you need a mounted wheel pair; Garvee's 1120642 4.80-12 set lists tires pre-mounted on rims.
Best suited to a buyer replacing one tire while retaining a compatible 12-inch wheel. Its 4.8-12 size and 990-pound capacity still need to match the trailer, and the tire-only format requires separate mounting.

View on AmazonAvoid the bolt-pattern mismatch trap
A 12-inch rim does not guarantee that an assembly fits your trailer: the bolt pattern and center bore must also match. The eCustomRim White 4.80-12 Assembly and eCustomRim Black 4.80-12 Assembly list a 5-lug-on-4.5-inch pattern and 2.95-inch center bore, while the eCustomRim 4-Lug Assembly uses 4 lugs on a 4-inch pattern and a 2.83-inch center bore. These are not interchangeable just because each uses a 12-inch rim and 4.80-12 tire.
Before ordering, count the wheel studs and measure the bolt circle using a suitable method; also check the hub and wheel specifications for center-bore compatibility. The Garvee listings also state a 5-on-4.5-inch pattern, but do not assume an unlisted center bore matches your current wheel.
If fitment details are missing, confirm them rather than inferring from tire size.
Why tire pressure figures are not a ranking shortcut
The listed maximum pressure differs across these products, so do not treat the largest PSI figure as a reason to inflate every tire to that value. eCustomRim’s 4.80-12 Load Range C assemblies state a 60 PSI maximum, while GarveeTech lists 90 PSI and the Garvee 5.30-12 set lists 80 PSI. The Garvee 4.80-12 listing also states a 90 PSI maximum.
These figures describe different products and do not establish one universal pressure for your trailer. Use the tire maker’s guidance and the trailer’s load information when determining operating pressure, and do not exceed the tire’s stated maximum.
A pressure figure alone also cannot establish whether a tire has sufficient capacity for a particular trailer: compare the tire’s load rating and the trailer’s required load as well.

Look for a tire size and per-tire load capacity that suit your trailer’s requirements. Most listings here are 4.80-12; the Garvee 5.30-12 Assembly is the size alternative and lists a 1,050-pound capacity per tire. The 4.80-12 Load Range C options from eCustomRim, Garvee, GarveeTech, WANDA, and AutoSteelix list 990 pounds per tire or per tire capacity, while eCustomRim Load B Tires list 785 pounds each.
Those needing the stated higher capacity may consider the 5.30-12 set, if its size fits. Buyers whose trailer specifies 4.80-12 should compare the listed capacity with their load needs rather than choosing a different size by capacity alone.
Wheel pattern and included rim
Check that the assembly’s bolt pattern matches your trailer before selecting a mounted tire set. Several options, including the eCustomRim White 4.80-12 Assembly and GarveeTech 4.80-12 Assembly, list a 5-on-4.5-inch pattern. The eCustomRim 4-Lug Assembly instead lists a 4-on-4-inch pattern, while the WANDA 4.80-12 Tires, AutoSteelix 4.80-12 Tires, and Forerunner QH502 Tire are tire-only listings without wheel-pattern details.
A mounted pair is convenient when the pattern matches; a tire-only product may suit a buyer who already has compatible wheels and plans to replace tires. Confirm center bore and wheel dimensions, too, where provided or required.
Construction, pressure, and warranty details
Compare the stated load range, ply rating, pressure limit, and warranty rather than assuming all 4.80-12 tires are identical. eCustomRim’s Load Range C assemblies list 990 pounds per tire and 60 PSI maximum; GarveeTech lists 6-ply Load Range C and 90 PSI, while Garvee’s 5.30-12 option lists 6-ply Load Range C, 1,050 pounds, and 80 PSI. eCustomRim Load B Tires list 785 pounds and 60 PSI.
Warranty details also differ: eCustomRim lists two years, GarveeTech lists none, Garvee lists 30 days for its 5.30-12 set, and Garvee’s 4.80-12 set lists three months. Match the specifications to your trailer and verify current requirements.
Which 12-inch trailer tire should you choose?
For a trailer requiring 4.80-12 tires on a 5-lug, 4.5-inch pattern, choose the eCustomRim White 4.80-12 Assembly for its 990-pound per-tire rating and clearly listed rim fitment. Choose the eCustomRim Black 4.80-12 Assembly if you want the same stated tire size, capacity, and bolt pattern with black rims. GarveeTech 4.80-12 Assembly is another mounted option, with a stated 90 PSI maximum.
If your trailer requires the 4-on-4-inch pattern, the eCustomRim 4-Lug Assembly is the relevant fit, not a 5-lug set. For a compatible trailer that needs the listed 5.30-12 size and higher stated capacity, consider Garvee 5.30-12 Assembly.
Buyers replacing tires on existing wheels can compare the tire-only WANDA or AutoSteelix options, while confirming fitment details first.

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 correct method for that lug count; for five lugs, measure from the center of one lug hole to the far edge of the opposite hole. Measure the center bore across its opening. Compare both measurements with your trailer’s hub before ordering.
Should I replace trailer tires based on age even if the tread looks usable?
Yes, age can matter even when tread remains, because trailer tires may deteriorate while sitting or from exposure. Check the tire’s date code and inspect for cracking, bulges, damage, or other signs of deterioration. Follow the tire maker’s replacement guidance, and have a qualified tire professional assess uncertain tires.
How should I set trailer tire pressure when the tire and trailer labels differ?
Do not treat the tire’s maximum pressure as an automatic target. Check the trailer maker’s cold-pressure recommendation and the tire’s stated limits, then confirm any conflict with the trailer or tire manufacturer before towing. Do not exceed the tire or wheel’s rated limits, and measure pressure when tires are cold.
What should I verify before choosing a mounted tire and wheel assembly?
Confirm the tire size, load capacity, lug count, bolt pattern, center bore, and pressure requirements against your trailer. Similar 12-inch assemblies can differ in wheel fitment and pressure specifications. For example, a 4-lug pattern is not interchangeable with a 5-lug pattern simply because the tire size matches.
When should I choose tire-only replacements instead of an assembly?
Choose tire-only replacements when your existing wheels are suitable and you want to reuse them; check that the tire size and load rating match your trailer. A mounted assembly may suit a replacement that includes both tire and rim, but verify its bolt pattern, center bore, capacity, and pressure requirements before ordering.
Final Words
For a trailer that fits a 5-lug-on-4.5-inch wheel, the eCustomRim White 4.80-12 Assembly is the overall pick, with two mounted tires rated at 990 pounds each and a stated 60 PSI maximum. Choose the black assembly for the same listed size, capacity, and pattern. For other options, match the exact tire size, load, and wheel fitment to your trailer; confirm pressure requirements before ordering.
