The best 235/80R16 trailer tire and wheel depends on your trailer’s required load rating, matching 8-lug bolt pattern, and preferred rim style. The Free Country black mod wheel is a straightforward choice for a 10-ply setup, while its white-spoke version adds listed tread and sidewall-protection features. ROCKMAN offers silver and black mod options with deeper listed tread, and GREMAX is the heavy-duty pick for trailers that require a 14-ply, load-range-G tire. Confirm fitment and ratings before ordering.

Free Country Black Mod 10-Ply Tire And Wheel
This Free Country assembly pairs an ST235/80R16 tire rated 10-ply and load range E with a black mod rim. The listing specifies an 8-on-6.5-inch bolt pattern, zero offset, and 7 mm tread depth. It gives a load index of 124 and lists a speed rating of up to 81 mph in the features.
Best for: Trailer owners seeking a 10-ply load-range-E assembly with a black mod wheel and a clearly stated bolt pattern. The deeper-than-5.6-mm tread claim is a listed feature, not a guarantee of mileage.
Check before buying: The title and features give different speed-rating letters: the title says 124N, while the features say M. Verify the tire’s sidewall markings and the seller’s current specifications.
ROCKMAN Silver Mod 10-Ply Tire And Wheel
ROCKMAN’s ST235/80R16 assembly is listed as 10-ply, load range E, with an 8-on-6.5-inch bolt pattern and zero-offset silver mod rim. Its features state 8 mm of tread depth and a speed rating of up to 81 mph. The listing title gives load index 124, but the feature text gives 123.
Best for: Buyers who want a silver mod appearance and a 10-ply tire with a listed 8 mm tread depth. It offers a similar size and wheel pattern to the other 10-ply options here.
Check before buying: The load index differs between the product title and feature details. Confirm the actual tire markings and required load capacity for your trailer rather than relying on one listing field.
Free Country White Spoke 10-Ply Tire And Wheel
This Free Country assembly is described as an ST235/80R16, 10-ply, load-range-E tire with a white-spoke wheel. Its listed features include a full nylon cap-ply overlay across the tread, a Scuff Guard ring on the tire wall, and 7 mm tread depth. The product name specifies an 8-on-6.5-inch wheel pattern.
Best for: Owners who want a white-spoke style and value the listed tread overlay and tire-wall guard features. The full-tread overlay is a specific construction detail to compare with products that list nylon strips only at the shoulders.
Check before buying: The provided feature details do not state a load index, speed rating, offset, or wheel material. Confirm those specifications and wheel fitment with the seller before purchase.
ROCKMAN Black Mod 10-Ply Tire And Wheel
This ROCKMAN option combines an ST235/80R16, 10-ply, load-range-E tire with a black mod rim. The listing specifies an 8-on-6.5-inch bolt pattern, zero offset, 8 mm tread depth, and a speed rating of up to 81 mph. Its feature text gives load index 123.
Best for: Buyers who want a black mod wheel and the ROCKMAN listing’s deeper 8 mm tread claim in a 10-ply package. Its stated fitment details make it easier to compare against trailers using an 8-on-6.5-inch pattern.
Check before buying: Confirm that load index 123 meets the trailer’s required tire capacity. The listed speed limit is not a substitute for following the trailer manufacturer’s operating guidance.
GREMAX 14-Ply All-Steel Black Mod Tire And Wheel
GREMAX lists this ST235/80R16 assembly as an all-steel radial tire with a 14-ply rating, load range G, load index 129, and a stated capacity of 4,080 pounds. Features also include a full nylon cap-ply overlay and 11/32-inch tread depth. The product name specifies an 8-on-6.5-inch black mod wheel.
Best for: Owners of heavy RVs or trailers whose specifications call for the listed load-range-G capacity. It is the higher-load option in this group, with a 14-ply rating rather than 10-ply.
Check before buying: Higher capacity does not make this tire appropriate for every trailer. Match the tire rating to the trailer’s axle, wheel, and manufacturer requirements; the provided features do not state a speed rating or wheel offset.
Buying Guide: How To Choose A 235/80R16 8-Lug Assembly
Does the bolt pattern match your trailer?
“8 lug” alone does not confirm fit. These listings identify an 8-on-6.5-inch pattern for most of the assemblies, but verify the exact bolt circle and wheel specifications against your current wheel or trailer documentation. Also check offset and hub fitment where applicable.
What load range and capacity do you need?
Choose a tire that meets the trailer manufacturer’s required capacity. The 10-ply options here are listed as load range E, while GREMAX is listed as 14-ply, load range G, with a 4,080-pound capacity. Do not assume that a higher rating is automatically suitable; check axle and wheel limits as well.
Which tread and construction details matter?
Compare the listed tread depths: Free Country cites 7 mm, ROCKMAN cites 8 mm, and GREMAX cites 11/32 inch. These measurements come from product details and do not establish real-world tire life. The Free Country white-spoke and GREMAX listings also describe a full nylon overlay; compare construction details with your needs.
Should you buy a tire and wheel together?
A pre-mounted assembly can simplify replacement when its size, pattern, load rating, and other fitment details match. If you need only a tire or have a specific wheel requirement, confirm that the assembly’s rim style, offset, and specifications are appropriate before selecting it.
Frequently Asked Questions
What does ST235/80R16 mean?
It identifies a special-trailer tire size and construction designation. Confirm that ST235/80R16 is the size specified for your trailer before replacing a tire.
Is every 8-lug trailer wheel an 8-on-6.5-inch wheel?
No. Lug count does not establish bolt-circle size. Measure or verify the wheel pattern before ordering.
Can I replace a load-range-E tire with load range G?
Only if the trailer, axle, wheel, and manufacturer specifications support the change. Check the required capacity and fitment rather than relying on ply rating alone.
What speed rating should I choose?
Use the speed rating required for your tire and follow the trailer manufacturer’s operating guidance. Verify the rating on the tire itself, especially when product title and feature details conflict.
Does deeper tread guarantee longer tire life?
No. Listed tread depth is one comparison point, but it does not guarantee mileage. Tire life also depends on use, maintenance, load, and operating conditions.
