The best match for a 13-inch, 4-lug trailer setup is a wheel with a 4-on-4-inch bolt pattern, but confirm the center bore and load requirements before buying. The eCustomRim 13×4.5-inch white spoke rim is best for buyers who need a wheel only; its two-pack tire assembly is better for replacing tires and wheels together. The other listed assemblies have 5-lug patterns, so they are not direct 4-lug replacements.

eCustomRim 4-Lug Two-Pack Assembly
Best for: Trailer owners replacing two tires and wheels who have a 4-on-4-inch bolt pattern. This product is a complete assembly, so it includes the tire, rim, and valve stem rather than the wheel alone.
The assembly uses a 13×4.5-inch rim with a 2.65-inch center bore. Its ST175/80D13 bias-ply tire has a stated maximum load of 1,360 pounds, a 50 PSI rating, Load Range C, and a 24.4-inch overall diameter. The listing says the tire, wheel, and valve stem are DOT-approved and includes a two-year manufacturer’s warranty with roadside assistance.
Check before choosing: Verify that your trailer uses the stated 4-on-4 pattern and that the center bore, tire size, and load rating suit the trailer. This is a bias-ply tire assembly, not a rim-only purchase.
eCustomRim 13-Inch White Spoke Wheel
Best for: Buyers who need a 4-lug rim but do not need a tire included. The listing identifies this as a trailer-specific 13×4.5-inch wheel with a 4-on-4-inch pattern, a 2.83-inch center bore, and a maximum load of 1,660 pounds.
Choose this wheel if your existing tire is suitable and you want to replace only the rim. Its stated load capacity is higher than the complete 4-lug assembly above, but that does not by itself establish the capacity of the entire trailer setup. The listing advises using its fitment guide.
Check before choosing: The rim does not include a tire in the product name or listed features. Confirm the center bore and all trailer fitment measurements; matching the lug count alone is not enough.
eCustomRim Five-Lug Load Range B Pair
Best for: Buyers whose trailer calls for a 5-on-4.5-inch pattern, not a 4-lug wheel. This two-pack includes ST175/80D13 bias-ply tires and 13×4.5-inch rims, with a 3.19-inch center bore.
The listed tire specifications include a 1,100-pound maximum load, 35 PSI, Load Range B, and a 24.4-inch overall diameter. The product description states that the tire, wheel, and valve stem are DOT-approved and lists a two-year manufacturer’s warranty with roadside assistance.
Important limitation: Its five-lug, 4.5-inch bolt pattern does not match a 4-on-4-inch hub. Avoid this option if your trailer requires four lugs.
HOPSHARK Five-Lug Tire Assembly
Best for: Trailer owners looking for a 13-inch tire and wheel assembly with a 5-on-4.5-inch pattern. The listing describes an ST175/80R13 tire with a 24-inch diameter, Load Range D, and a stated maximum load of about 1,433 pounds. It also mentions a free center cap and says the assembly is inflated before packing.
Important limitation: This is a five-lug assembly and is not a direct fit for a 4-lug hub. The product details give both 1,435 and 1,433 pounds as the maximum load, so check the tire’s markings and seller information before relying on a load figure.
Tbest Steel Spoke Trailer Wheel
Best for: Buyers comparing a steel trailer wheel who can confirm its exact fitment before purchase. The listing describes a 13×4.5J steel wheel with a spoke design and says it is intended for trailer applications.
Important limitation: The supplied features do not state the bolt pattern, center bore, or load rating. Do not assume it fits a 4-lug trailer based on its 13-inch size. Request or verify those specifications before choosing it.
Buying Guide: How To Choose A 13-Inch 4-Lug Rim
How do you confirm the bolt pattern?
For these listings, “4 on 4 inches” means four lug holes arranged on a 4-inch bolt circle. Match the wheel’s bolt pattern to the trailer hub. A 5-on-4.5-inch wheel has a different number of lugs and spacing, so it is not interchangeable with a 4-on-4 wheel.
Should you buy a rim or a complete assembly?
Choose a wheel-only product if your tire is in usable condition and you need only a rim. Choose a complete assembly if you want the tire, wheel, and valve stem together. Check whether the listing sells one assembly or a pair, and confirm the tire dimensions and type match your trailer requirements.
Which measurements and ratings matter?
- Bolt pattern: Confirm the lug count and bolt-circle measurement.
- Center bore: Compare the wheel’s stated center bore with the hub requirements.
- Load capacity: Check the tire and wheel ratings against the trailer’s required load; do not treat one component’s rating as the whole trailer’s capacity.
- Tire details: Verify size, construction, load range, and inflation requirements where a tire is included.
- Fitment guidance: If a listing omits key measurements, obtain confirmation before ordering.
Frequently Asked Questions
Are all 13-inch trailer rims 4 lug?
No. Wheel diameter does not determine lug count. Check the stated bolt pattern, such as 4 on 4 inches or 5 on 4.5 inches.
Can a 5-lug wheel fit a 4-lug hub?
Not as a direct match. The lug count and bolt pattern must match the hub.
What does 13×4.5 mean?
It describes a 13-inch wheel diameter and a 4.5-inch width. It does not specify the bolt pattern or center bore.
Is a wheel-only listing the same as a tire assembly?
No. A wheel-only product is a rim, while a tire assembly includes a tire mounted with the wheel and may include a valve stem.
What should I do if the bolt pattern is not listed?
Do not assume fitment. Ask the seller for the bolt pattern, center bore, and load rating, then compare them with your trailer’s specifications.
