A strong Carry-On trailer tire choice matches your trailer’s required tire size, load rating, and wheel bolt pattern; this selection suits owners replacing tires on utility, boat, cargo, and recreational trailers. The products range from compact 4.80-8 and 5.70×8 assemblies to 15-inch options, with bias-ply and radial designs and both tire-only and pre-mounted packages. Our leading pick, eCustomRim 15-Inch Assembly, pairs a 1,820-pound maximum load with a 5-lug, 4.5-inch bolt pattern, but it is right only if those dimensions match your trailer.
Carry-On is not identified as a product brand in the supplied listings, so treat these as candidate replacements—not guaranteed Carry-On fitments. Check your existing tire sidewall, hub pattern, clearance, and axle requirements before ordering.
The eCustomRim 15-Inch Assembly is the strongest all-around candidate in this selection because it is a pre-mounted ST205/75D15 bias-ply assembly rated for 1,820 pounds at 50 PSI and uses a 5-lug, 4.5-inch bolt pattern. It is a useful match only for a trailer that calls for those specifications. If your Carry-On trailer requires a different tire size, load range, or hub pattern, choose the matching option below instead of assuming the leading pick will fit.

Detailed Reviews: Best Carry On Trailer Tires

#1 · Best Overall
1. eCustomRim 15-Inch Assembly
- Size: Set of 2
- Rim Size: 15 in
- Weight: 72 lb
Best for: 15-inch five-lug replacement set.
Why it ranks #1: The pre-mounted ST205/75D15 tire supports 1,820 pounds at 50 PSI and its 5-lug, 4.5-inch pattern suits a common replacement configuration.
A pair of pre-mounted ST205/75D15 bias-ply assemblies combines Load Range C tires with 15-by-5-inch rims. That package gives trailer owners both tires and wheels together, while the 5-on-4.5-inch bolt pattern and 3.19-inch center bore identify the wheel setup it is made to fit.
Each tire is rated for a maximum 1,820-pound load at 50 PSI, giving buyers concrete load and inflation figures to check against their trailer needs. The 27.2-inch overall diameter and ST205/75D15 size help assess tire and clearance compatibility. Since the assemblies include 15-by-5-inch rims with a 5-on-4.5-inch pattern and 3.19-inch center bore, replacement involves a mounted tire-and-wheel package rather than sourcing rims separately; the listed fitment dimensions remain important.
- Two pre-mounted trailer tire and wheel assemblies
- ST205/75D15 bias-ply tire size
- Maximum load of 1,820 pounds per tire at 50 PSI
- 15-inch rim with 5-on-4.5-inch bolt pattern
- Bias-ply construction rather than radial construction.
Skip it if you need radial tires or a different wheel pattern; these are bias ply with 5 lugs on 4.5 inches.
A trailer owner replacing a matching pair can use this set to get tires and 15-inch rims together. Choose it only when the ST205/75D15 size, load needs, and five-lug wheel dimensions suit the trailer.

#2 · Best 13-Inch Fit
2. eCustomRim 13-Inch Assembly
- Size: 175/80D13
- Rim Size: 13 in
- Weight: 54 lb
Best for: 13-inch five-lug mounted pair.
Why it ranks #2: This two-assembly ST175/80D13 package includes valve stems, a 5-lug, 4.5-inch pattern, and a 1,360-pound maximum load per tire.
Two pre-mounted ST175/80D13 assemblies include valve stems, pairing Load Range C bias-ply tires with 13-inch rims. The 5-on-4.5-inch bolt pattern and 3.19-inch center bore make this a specific replacement option for compatible utility and recreational trailer wheels.
Each tire carries a maximum load rating of 1,360 pounds at 50 PSI, and the 24.4-inch overall diameter helps buyers assess capacity and clearance. Since both tires are already mounted and the package includes valve stems, it combines several replacement components in one purchase. The 13-by-4.5-inch rims use a 5-on-4.5-inch pattern and 3.19-inch center bore, so checking those hub dimensions remains essential before fitting.
- Two pre-mounted ST175/80D13 assemblies with valve stems
- Maximum 1,360-pound load per tire at 50 PSI
- 13-inch rims with 5-on-4.5-inch bolt pattern
- Listed 24.4-inch overall diameter
- The listed inflation limit is 50 PSI.
Skip it if you require tires rated above 50 PSI; these bias-ply assemblies list a 50 PSI maximum.
This pair is for owners replacing matching 13-inch trailer assemblies and wanting valve stems included. Verify the ST175/80D13 size, five-lug pattern, center bore, clearance, and load needs before installation.

#3 · Radial Pick
3. Kenda Karrier Radial
- Size: 145R12
- Rim Size: 12 in
Best for: Radial tire for 12-inch rims.
Why it ranks #3: The ST145R12 radial has Load Range E, a 10-ply rating, and a listed 1,520-pound capacity for buyers whose trailer requires this size.
Radial construction sets the Kenda Karrier apart from the bias-ply options in this roundup, and its ST145R12 size identifies a trailer tire for a 12-inch rim. Its stated 1,520-pound load capacity gives buyers a specific figure to weigh against their trailer’s requirements.
The 10-ply-rated Load Range E specification identifies this tire’s construction and load range, while the listed capacity is 1,520 pounds. Those figures help buyers compare the tire with their trailer’s demands rather than relying on size alone. The 145/100R12 metric description and 12-inch rim size help establish compatibility. This is a tire, not a listed tire-and-wheel assembly, so installation requires an appropriate rim that is not included in the supplied product information.
- Radial trailer tire construction
- ST145R12 size for a 12-inch rim
- Load Range E, 10-ply rated
- Listed load capacity of 1,520 pounds
- Tire only; a rim is not included in the supplied product information.
Skip it if you need a mounted wheel assembly; this listing identifies a tire, while the Garvee 4.80-12 set includes rims.
This Kenda suits a trailer owner seeking an ST145R12 radial tire and already arranging a compatible 12-inch rim. Confirm its size and 1,520-pound listed capacity meet the trailer’s fit and load requirements.

#4 · Galvanized Wheel
4. Antego 5.70×8 Assembly
- Size: (Set of 2)
- Rim Size: 8 in
Best for: Small-trailer galvanized wheel pair.
Why it ranks #4: This set of two pre-mounted 5.70×8 tires has 6-ply Load Range C construction and galvanized 4-lug steel wheels.
A galvanized four-lug steel wheel comes pre-mounted with each 5.70×8 tire, giving small-trailer owners a ready tire-and-wheel replacement pair. The 8-inch wheel and Load Range C, 6-ply tire construction make it a focused option for compatible boat, utility, cargo, or small trailers.
Because the tires and rims arrive as assemblies, replacing a matching wheel does not require sourcing a separate rim. The 5.70×8 tire size and four-lug wheel call for checking the existing trailer’s tire dimensions and hub pattern before installation. Its 8-inch rim is 3.75 inches wide, a useful dimension to compare with the trailer’s available space. The galvanized steel wheel provides a specified wheel finish, while the tire is 6-ply rated Load Range C.
- Set of two pre-mounted tire and wheel assemblies
- 5.70×8 tire size with 8-inch rims
- Galvanized four-lug steel wheels
- 6-ply rated Load Range C tires
- The product listing does not specify a maximum load or inflation pressure.
Skip it if you need a stated load rating or pressure before choosing; this listing supplies neither figure.
Choose this pair for a compatible small boat, cargo, utility, or other trailer when an 8-inch, four-lug assembly matches. Its 5.70×8 size and 3.75-inch rim width should suit the available clearance.

5. GarveeTech 4.80-12 Assembly
- Size: 4.80-12
- Rim Size: 12 in
- Weight: 39.7 lb
Best for: 12-inch five-lug trailer set.
Why it ranks #5: The two 4.80-12 bias-ply tires are rated for 990 pounds each at 90 PSI and arrive on 12-inch, 5-lug wheels.
Two 4.80-12 bias-ply tires arrive mounted on white 12-inch spoke wheels, so replacement can cover both tire and rim in one assembly. Their 5-on-4.5-inch pattern and Load Range C rating make this set a candidate for compatible utility or boat trailers.
The tires are rated to carry up to 990 pounds each at 90 PSI, and their 6-ply Load Range C construction gives buyers a defined capacity to compare with trailer requirements. Nylon cord layers and double steel belts are listed as construction features for towing stability and durability. With 12-inch wheels already mounted and a 5-lug, 4.5-inch bolt pattern, the pair simplifies wheel replacement when those dimensions match the trailer hub.
- Set of two mounted 4.80-12 assemblies
- Load Range C, 6-ply tires
- Maximum 990-pound load per tire at 90 PSI
- 12-inch white spoke wheels with 5-on-4.5-inch pattern
- The 5-lug pattern will not suit trailers requiring a different wheel pattern.
Skip it if you need a four-lug wheel or another bolt pattern; the listed wheels use five lugs on 4.5 inches.
This pair suits owners of compatible utility, boat, camper, or travel trailers who want 12-inch wheels and tires supplied together. Check the 4.80-12 size, load requirement, and five-lug pattern against the trailer.

6. Garvee 4.80-12 Assembly
- Size: 4.80-12
- Rim Size: 12 in
- Weight: 39.7 lb
Best for: Four-lug 12-inch trailer pair.
Why it ranks #6: This two-pack offers 6-ply Load Range C tires rated at 990 pounds each, mounted on black 12-inch rims with a 4-lug, 4-inch pattern.
A pair of 4.80-12 tires comes on black 12-by-4-inch steel rims with a four-lug, 4-inch bolt pattern. This mounted combination offers a defined fitment for compatible utility, boat, camper, or cargo trailers and avoids sourcing separate rims.
The 6-ply Load Range C tires are rated for up to 990 pounds at 90 PSI, giving buyers concrete capacity and pressure figures to compare with their trailer’s requirements. The supplied 12-inch rims have a four-lug pattern on 4 inches, which identifies the hub fitment to check. Because the package includes two tires with rims, it can simplify a paired replacement; the 4.80-12 size and rim dimensions still need to match the trailer.
- Two 4.80-12 tires with rims
- Load Range C, 6-ply construction
- Maximum 990-pound load per tire at 90 PSI
- 12-inch black steel rims with four-lug, 4-inch pattern
- The four-lug, 4-inch pattern will not fit a trailer with a different hub pattern.
Skip it if you need five-lug wheels; these rims use four lugs on a 4-inch bolt pattern.
This pair suits a buyer replacing two assemblies on a compatible 12-inch, four-lug trailer wheel setup. Match the 4.80-12 size, bolt pattern, and stated 990-pound per-tire capacity to the trailer.

#7 · Compact Wheel
7. Garvee 4.80-8 Assembly
- Size: 4.80-8
- Rim Size: 8 in
- Weight: 19 lb
Best for: Four-lug 8-inch utility set.
Why it ranks #7: The pre-mounted 4.80-8 tires fit an 8-inch wheel setup and provide a listed 760-pound capacity per tire with a 4-lug, 4-inch pattern.
The two 4.80-8 tires arrive mounted on 8-by-3.75-inch white rims with a four-lug, 4-inch bolt pattern. That combination gives compatible utility, boat, cargo, or other trailer owners a matched pair and defined wheel dimensions for replacement planning.
Each tire is rated for up to 760 pounds and a maximum 90 PSI, allowing buyers to compare its stated capacity with their trailer’s load needs. The 16.3-inch overall diameter and 4.76-inch section width help assess available clearance, while the 2.85-inch center bore and four-lug, 4-inch pattern describe the wheel fitment. With tires already on 8-inch rims, the pair avoids purchasing separate wheels, provided those dimensions match.
- Two 4.80-8 tire and wheel assemblies
- Four-lug wheels with a 4-inch bolt pattern
- Maximum 760-pound load per tire at 90 PSI
- Listed 16.3-inch overall diameter and 4.76-inch section width
- Each tire’s listed maximum load is 760 pounds.
Skip it if you need more than 760 pounds of capacity per tire; this set lists 760 pounds maximum for each tire.
This set fits buyers replacing a pair on a compatible small utility, boat, cargo, or similar trailer. Check the four-lug pattern, 2.85-inch center bore, clearance, and per-tire load before selecting it.

8. Free Country Grand Ride
- Size: 225/75R15 10PR
- Rim Size: 15 in
- Weight: 28.8 lb
Best for: Four-tire radial replacement set.
Why it ranks #8: Each ST225/75R15 tire is listed at 2,830 pounds with Load Range E, 10-ply construction, and a sidewall scuff guard.
Four steel-belted radial ST225/75R15 tires make this the roundup’s listed four-tire set, with Load Range E, 10-ply construction. That format suits a buyer replacing a full matching group, while the stated 2,830-pound load capacity offers a figure to compare with trailer requirements.
The ST225/75R15 size and 15-inch rim specification help establish whether these tires match the trailer’s existing setup. Steel-belted radial construction and the 10-ply Load Range E rating give buyers defined construction details when evaluating a replacement. Free Country’s Scuff Guard adds protection to the sidewall and rim, which can help limit damage in those areas. The four-tire quantity is useful for a full set replacement, but buyers should check tread depth before purchasing.
- Set of four trailer tires
- Steel-belted radial construction
- ST225/75R15 size with Load Range E, 10-ply rating
- Scuff Guard adds sidewall and rim protection
- The set contains four tires, which may exceed a buyer replacing only one or two.
Skip it if you are replacing only one tire; this listing is a four-tire set rather than an individual replacement.
A trailer owner replacing all four tires can consider this set for a 15-inch ST225/75R15 setup. Check the stated 2,830-pound capacity, fit, and tread depth before choosing this Load Range E group.

9. Transeagle ST Radial II
- Size: 205/75R15
- Rim Size: 15 in
- Weight: 29 lb
Best for: 15-inch radial tire-only replacement.
Why it ranks #9: This tire-only ST205/75R15 radial has a listed 2,403-pound capacity and 10-ply Load Range E construction, but no rim is included.
The Transeagle ST Radial II is a 10-ply, Load Range E radial tire in ST205/75R15 size, with a listed 2,403-pound load capacity. It suits trailer owners seeking a radial replacement for a 15-inch wheel, while its tire-only format leaves the rim to source separately.
Its ST205/75R15 size and 15-inch rim specification help determine whether it matches the existing wheel setup. The 10-ply Load Range E rating and 2,403-pound capacity offer concrete details for comparing load demands. The listing identifies this as a tire only, so installation calls for a suitable rim already on hand or sourced separately. Buyers should also account for the tire’s size when checking trailer clearance; no mounted assembly is specified.
- ST205/75R15 radial trailer tire
- Load Range E, 10-ply rating
- Listed 2,403-pound load capacity
- 15-inch rim size
- Tire only; no wheel is included.
Skip it if you need a mounted tire and wheel; the Garvee 4.80-12 set includes rims, unlike this tire-only listing.
This tire suits a buyer needing an ST205/75R15 radial and already equipped to mount it on a compatible 15-inch rim. Check the 2,403-pound capacity and trailer clearance before selecting it.

10. WANDA ST205/75D15 Tires
- Size: 205/75D15 Pack of 2
- Rim Size: 15 in
- Weight: 39.2 lb
Best for: Deep-tread 15-inch bias pair.
Why it ranks #10: The pair of bias tires supports 1,820 pounds each at 50 PSI, but tires-only packaging and a 5.5-inch rim-width requirement reduce convenience.
A deeper tread distinguishes this pair of Free Country ST205/75D15 bias tires, which are listed as 6-ply Load Range C and sold without rims. The stated 1,820-pound maximum load at 50 PSI gives trailer owners specific figures to compare before arranging installation on suitable 15-inch wheels.
The ST205/75D15 size and 15-inch rim specification help establish whether these tires match an existing trailer setup. A maximum load of 1,820 pounds at 50 PSI provides the listed capacity and inflation ceiling, while the 6-ply Load Range C construction identifies the tire rating. The deeper tread is described as supporting longer life. Since rims are not included, buyers need suitable wheels separately; the listed rim width is 5.5 inches.
- Pair of ST205/75D15 bias tires
- 6-ply Load Range C construction
- Maximum 1,820-pound load at 50 PSI
- Deeper tread described as supporting longer life
- Rims are not included.
Skip it if you need tires and wheels together; the eCustomrim ST205/75D15 pair includes mounted assemblies.
This pair suits a trailer owner replacing ST205/75D15 tires while keeping or sourcing compatible rims separately. Check the 5.5-inch rim width, 50 PSI limit, and 1,820-pound capacity against the trailer’s requirements.

View on AmazonAvoiding a mismatched replacement wheel
A tire that matches the sidewall size can still be incompatible if its wheel does not match the trailer hub. The listings show why both details matter: eCustomRim’s 13-inch assembly uses a 5-lug, 4.5-inch pattern and a 3.19-inch center bore, while Garvee’s 4.80-12 assembly uses a 4-lug, 4-inch pattern. GarveeTech offers a 4.80-12 assembly with a different, 5-lug, 4.5-inch pattern.
Those wheel patterns are not interchangeable just because two products share a nominal tire size. Before buying an assembly, compare the existing wheel’s lug count, bolt-circle measurement, center bore, and rim width with the listing.
Also check tire diameter and space around the fender, suspension, and frame. The product information does not establish Carry-On-specific compatibility, so verify the trailer’s own requirements rather than relying on a brand name or broad trailer category.
Tire-only versus pre-mounted assemblies
A tire-only purchase requires you to reuse or separately source a compatible wheel, while an assembly provides a tire already mounted to its listed rim. Several choices here are assemblies, including the eCustomRim, Garvee, GarveeTech, and Antego options; Transeagle and WANDA are explicitly tire-only. This distinction can be a source of a costly installation mistake: selecting a tire-only listing when you need a complete wheel, or choosing an assembly whose bolt pattern does not match your hub.
Radial and bias-ply construction is another real trade-off in this set, not a universal performance verdict. Kenda and Transeagle are radial listings, while multiple assembled options specify bias ply.
Choose based on the replacement type your trailer calls for and the exact fitment requirements; the supplied information does not establish that one construction is best for every trailer.
How to Choose Carry-On Trailer Tires
Tire size and wheel diameter
Start by matching the tire size printed on your current tire or specified for your trailer. The choices here span 4.80-8 and 5.70×8 tires on 8-inch rims, 4.80-12 and ST145R12 options on 12-inch rims, ST175/80D13 on 13-inch rims, and ST205/75D15 and ST225/75R15 on 15-inch rims. These sizes are not substitutes for one another; diameter and section width can affect trailer clearance.
Compact 8-inch options suit trailers that already require that size, while the 15-inch choices serve trailers specified for larger tires. Do not pick by wheel diameter alone: match the full tire designation and confirm that the tire clears the trailer when mounted and loaded.
Load rating and inflation
Choose a tire whose load capacity meets or exceeds the requirement for your trailer, and follow the tire and trailer maker’s inflation guidance. Listed capacities vary from 760 pounds per tire for Garvee’s 4.80-8 to 2,830 pounds for each Free Country Grand Ride tire. Other examples include 990 pounds for the 4.80-12 options, 1,360 pounds for the eCustomRim 13-inch assembly, and 1,820 pounds for its 15-inch assembly.
Several products also specify pressure, including 50 PSI for the eCustomRim bias tires and 90 PSI for the Garvee 4.80-12 models. Higher listed capacity does not make a tire suitable if its size or fitment is wrong.
Match the trailer’s required tire rating and account for the load on each tire.
Wheel fit and package type
Check the lug pattern and decide whether you need a complete wheel assembly or a tire alone. The assemblies in this group include patterns such as 5 lug on 4.5 inches, 4 lug on 4 inches, and the Antego 4-lug galvanized wheel; a matching tire size does not guarantee a matching hub. Some pre-mounted pairs simplify replacement when their wheel dimensions match, while the WANDA pair and Transeagle listing are tires only.
For example, eCustomRim’s 15-inch assembly has a 5-lug, 4.5-inch pattern, while Garvee’s 4.80-12 assembly has a 4-lug, 4-inch pattern. Buyers replacing a whole wheel should verify bolt circle, center bore, and rim width; buyers reusing a wheel should confirm the tire fits that rim.
Which Carry-On Trailer Tire Should You Choose?
For a trailer specified for ST205/75D15 tires on a 5-lug, 4.5-inch wheel, choose eCustomRim 15-Inch Assembly: it combines a mounted wheel with a 1,820-pound maximum load rating. If your trailer needs 13-inch tires with the same listed 5-lug, 4.5-inch pattern, eCustomRim 13-Inch Assembly is the closer match and includes valve stems. For a 12-inch radial tire in Load Range E, consider Kenda Karrier Radial; for a compact 8-inch setup with a 4-lug, 4-inch pattern, Garvee 4.80-8 Assembly is the listed option.
Choose GarveeTech 4.80-12 Assembly only when its 5-lug, 4.5-inch wheel matches your hub. Confirm size, load, pattern, and clearance against your trailer before ordering; none is identified as a guaranteed Carry-On fit.
Frequently Asked Questions
How do I confirm the correct tire size and load rating for my Carry-On trailer?
Check the trailer’s tire placard or owner’s manual first, then compare its required size and load rating with the tire sidewall and product listing. Confirm the wheel and tire assembly also matches the hub and has adequate capacity for the trailer’s requirements. Do not assume a similar-looking size or a higher load rating guarantees fit.
How can I measure my trailer wheel’s bolt pattern and center bore?
Count the wheel’s lug holes and measure the bolt pattern using the distance between the appropriate lug-hole centers; for an even number of lugs, measure across opposite holes. Measure the center bore across the opening at the wheel’s center. Compare both measurements with the trailer hub and product details, and verify fit before ordering.
When should trailer tires be replaced because of age or visible damage?
Replace a tire if you find sidewall cracks, bulges, exposed cords, deep cuts, or other damage that may affect its integrity. Tread condition alone may not reveal age-related deterioration, so check the tire’s date code and follow the tire or trailer maker’s replacement guidance. Have questionable tires inspected before towing.
Should I choose a tire-only listing or a tire-and-wheel assembly?
Choose a tire-only listing if you need a tire and already have a compatible wheel; choose an assembly if you need the wheel included. Before selecting an assembly, check its tire size, load rating, bolt pattern, and center bore against your trailer. A mounted wheel does not guarantee that it fits your hub.
How do I know whether a tire’s load capacity is sufficient?
Compare the listed load rating and capacity with the requirements in your trailer documentation and the weight each tire must support. Account for the trailer’s loaded condition and follow the manufacturer’s guidance; do not exceed the tire or trailer limits. If the needed capacity is unclear, confirm it with the trailer or tire manufacturer.
Final Words
The eCustomRim 15-Inch Assembly is the strongest all-around candidate here, but only for trailers specified for ST205/75D15 tires and a 5-lug, 4.5-inch pattern. Choose the 13-inch assembly, 12-inch radial, or compact 8-inch option when those specifications match your trailer instead. Before ordering, verify tire size, load rating, hub pattern, center bore, and clearance; none of these listings is a guaranteed Carry-On fit.
