The best tire and wheel assembly depends on your vehicle, tire size, load needs, and bolt pattern. For common 13-inch trailer replacements, the eCustomrim and Garvee ST175/80D13 sets offer matching core dimensions; choose between them based on listed details and package needs. The GarveeTech set is better for buyers needing a larger ST205/75D15 assembly, while the eCustomrim golf cart set is designed for carts and similar vehicles. Confirm your existing size and wheel measurements before ordering.

eCustomrim ST175/80D13 Trailer Assembly
This two-pack is best for trailer owners replacing compatible 13-inch tire and wheel assemblies. Each bias-ply tire has a stated maximum load of 1,360 pounds and maximum pressure of 50 PSI, with a 24.4-inch overall diameter and Load Range C. The 13-by-4.5-inch rim has a 3.19-inch center bore and a five-lug, 4.5-inch bolt pattern.
Choose this set if you need the specified 13-inch dimensions and want the tire, wheel, and valve stem supplied as an assembly. The listing describes the assembly as DOT-approved and includes a two-year manufacturer’s warranty with roadside assistance. Confirm that the load rating and wheel measurements suit your trailer. The listing does not establish compatibility with every trailer.
eCustomrim 8-Inch Golf Cart Assembly
This four-pack is best for golf cart owners who need a pre-mounted assembly rather than a trailer tire. It includes 18-by-8.5-8, four-ply sawtooth tires on glossy white 8-by-8-inch steel wheels. The wheels use a four-lug, 4-inch bolt pattern. The listing identifies the tires as suitable for turf, greens, and street use and describes them as a direct OEM factory replacement.
The tires and wheels arrive mounted and aired up, which can simplify installation. The listing also names utility vehicles and mowers as possible applications. Choose this set if your vehicle uses the listed tire and bolt pattern; avoid assuming it fits based only on vehicle type. Verify the existing wheel dimensions and lug layout before purchase.
Garvee ST175/80D13 Trailer Tire Set
This two-pack is best for buyers seeking ST175/80D13 trailer assemblies on 13-inch wheels. The listed tires have a maximum load of 1,360 pounds and maximum pressure of 50 PSI. Each white wheel measures 13 by 5 inches and has a five-lug, 4.5-inch bolt pattern. The stated section width is 6.96 inches.
Garvee describes the assemblies as DOT-approved and notes a variable-pitch design intended to reduce road noise. This may suit a buyer prioritizing a complete replacement set with the specified wheel pattern. Check the exact rim width and other fitment measurements against your trailer, since the listing does not give a center-bore measurement in the provided specifications.
GarveeTech ST205/75D15 Trailer Assembly
This two-pack is best for trailers that require an ST205/75D15 tire and 15-inch wheel. The tires are bias ply, Load Range C, and six-ply rating, with a listed maximum load of 1,820 pounds at 50 PSI. They are mounted on white spoke wheels with a five-lug, 4.5-inch bolt pattern. The listing names utility, boat, and travel trailers as intended applications.
Choose this assembly when your trailer’s required tire size and load specifications match the listing. The product description cites nylon cord layers and double steel belts as construction features and says the assemblies are pre-mounted for replacement. Do not substitute this larger tire size for a different required size without checking clearance and manufacturer specifications.
eCustomrim ST175/80D13 B78-13 Set
This eCustomrim two-pack is another option for trailers requiring ST175/80D13 assemblies. Its listed specifications include bias-ply tires, Load Range C, a 1,360-pound maximum load, 50 PSI maximum pressure, and a 24.4-inch overall diameter. The 13-by-4.5-inch rims have a 3.19-inch center bore and five lugs on a 4.5-inch bolt pattern.
It is best for buyers whose existing setup matches these measurements and who want the tire, rim, and valve stem supplied together. The listing states that the assembly is DOT-approved and includes a two-year manufacturer’s warranty with roadside assistance. Its listed core specifications overlap with the other eCustomrim ST175/80D13 option, so compare the full product details and confirm fitment rather than relying on the B78-13 wording alone.
Buying Guide: How To Choose A Tire And Wheel Assembly
Which tire size should I match?
Start with the size printed on your current tire or specified in your vehicle or trailer documentation. The products here include ST175/80D13, ST205/75D15, and 18×8.5-8 sizes. These are not interchangeable by default. A different diameter or width can affect clearance and operation.
How do I check wheel fitment?
Compare wheel diameter, rim width, lug count, bolt pattern, and center bore where provided. For example, several trailer options have five lugs on a 4.5-inch pattern, while the golf cart set has four lugs on a 4-inch pattern. Matching only the number of lugs is not enough; the bolt pattern must also match.
What load rating and pressure matter?
Check the assembly’s listed maximum load and pressure against your vehicle requirements. Do not exceed the specified limit, and follow the vehicle or tire manufacturer’s inflation guidance. A higher-looking load figure alone does not make an assembly appropriate if its size or fitment is wrong.
Should I choose a mounted assembly?
A complete tire and wheel assembly can reduce the separate mounting steps. Confirm whether the listing says it arrives mounted and aired up, as the golf cart product does. Regardless, inspect the product details and installation requirements for your vehicle before use.
Frequently Asked Questions
Can I use a golf cart tire assembly on a trailer?
Not based on these listings. The golf cart assembly has a different tire size and four-lug, 4-inch bolt pattern. Use an assembly specified for the vehicle and verify its fitment.
Are the ST175/80D13 options the same size?
They share the listed ST175/80D13 tire size and several core specifications, but the product listings differ. Compare the full details and verify wheel fitment before choosing.
What does a five-lug, 4.5-inch pattern mean?
It describes a wheel with five lug positions arranged on a 4.5-inch bolt circle. Confirm that this pattern matches your hub, along with the center bore and wheel dimensions.
Does DOT approval confirm fit on my vehicle?
No. DOT approval, when stated in a listing, does not establish that the assembly fits a particular vehicle. Check tire size, load requirements, and wheel measurements separately.
