eCustomrim B78-13 Load Range C Two-Pack
This two-pack is listed as an ST175/80D13 B78-13 trailer tire and rim assembly with five lugs and Load Range C. It is best for buyers who want a matched pair and whose trailer’s wheel specifications align with the assembly. It was selected because its title directly identifies the requested tire size and five-lug configuration. The listing details provided do not state the bolt-circle measurement, so confirm it with the seller before choosing this option.
eCustomrim Load Range C Two-Pack
This eCustomrim package includes two bias-ply assemblies. Each tire is listed with a maximum load of 1,360 pounds and maximum pressure of 50 PSI. The 13-by-4.5-inch rim has a 3.19-inch center bore and a five-lug, 4.5-inch bolt pattern. The listing also specifies a 24.4-inch overall diameter and DOT-approved tire, wheel, and valve stem.
Choose this set if your trailer requires the stated rim dimensions and bolt pattern. Those fitment measurements make it easier to compare against an existing wheel. The listing mentions a two-year manufacturer’s warranty with roadside assistance. Avoid this choice if your trailer’s required load capacity or wheel pattern differs; confirm both before installation.
Garvee White-Rim ST175/80D13 Two-Pack
Garvee’s two-piece set pairs ST175/80D13 tires with white 13-by-5-inch wheels. The listed pattern is five lugs on 4.5 inches, and the tire maximum load is 1,360 pounds at a maximum pressure of 50 PSI. The product is described as pre-assembled and DOT approved.
This is best for buyers replacing two assemblies who prefer a white wheel and need the listed 5-on-4.5-inch pattern. Garvee also describes a variable-pitch design intended to reduce road noise, but the provided specifications do not state a load range. Check the tire sidewall information and trailer requirements rather than assuming a rating that is not listed.
Garvee Black-Spoke Load Range C Two-Pack
This two-pack combines ST175/80D13 bias-ply tires with black 13-by-4.5-inch steel rims. Garvee lists six-ply construction, Load Range C, a maximum load of 1,360 pounds, and maximum pressure of 50 PSI. The wheel pattern is five lugs on 4.5 inches.
Choose this assembly if you want black spoke wheels and the stated load and fitment specifications match your trailer. The product description presents the bias-ply design as suitable for stable handling on uneven terrain. One limitation is that the listed tire construction and fitment do not replace checking the trailer’s required capacity, bolt pattern, and inflation guidance.
Free Country White-Spoke ST175/80D13 Assembly
Free Country lists this tire and wheel with a white spoke rim, five lugs on a 4.5-inch pattern, zero offset, and a six-ply Load Range C tire. Its listed load index is 91, and its speed rating is L, up to 75 mph. The listing also gives a 7 mm tread depth.
This option is best for buyers who want a white-spoke assembly and value having a stated speed rating and tread-depth measurement for comparison. Keep the 75-mph limit in mind: do not treat it as an unrestricted highway-speed tire. Verify that the trailer’s axle load and wheel dimensions are suitable before ordering.
Buying Guide: How To Choose A 5-Lug ST175/80D13 Assembly
Does five-lug mean the wheel will fit?
No. A five-lug count alone does not confirm fitment. Check the bolt-circle measurement, center bore, rim width, and offset where provided, then compare them with the trailer’s existing wheel or manufacturer specifications. Several options here list a 5-on-4.5-inch pattern, but do not assume every five-lug wheel uses that measurement.
What load rating and pressure should I compare?
Match the tire’s capacity to the trailer’s required load, including the relevant axle and tire limits. Some products list a 1,360-pound maximum load and 50 PSI; the Free Country listing instead specifies a load index and speed rating. Follow the tire and trailer instructions for inflation, and do not exceed the stated limits.
Should I choose a single assembly or a two-pack?
A two-pack can suit a buyer replacing a pair, while a single assembly may be preferable when only one wheel needs replacement. Confirm the package quantity and ensure the replacement matches the other tires’ size and required specifications.
What does pre-assembled or DOT-approved tell me?
Pre-assembled means the tire and wheel are supplied together, which can simplify replacement. DOT approval is listed for some products, but it does not establish that a particular assembly fits your trailer. Fitment and load requirements still need to be checked.
Frequently Asked Questions
What does ST175/80D13 mean?
It is the tire size designation used by the listings. Confirm that this exact size is specified for your trailer before replacing its tires.
Is a 5-lug wheel automatically a 5-on-4.5-inch wheel?
No. Five lugs describe the lug count, not the bolt-circle size. Measure or verify the pattern before buying.
Are these assemblies sold individually or in pairs?
The eCustomrim and Garvee products identified as two-packs include two assemblies. The Free Country listing does not specify a two-pack in its provided product name, so check the listing for quantity.
Can I exceed the listed tire speed rating?
No. The Free Country listing specifies a maximum speed rating of 75 mph. Follow the tire’s stated limit and applicable trailer guidance.
