How to Use Radial Ply Tires on Wheels with a 4 on 4 Bolt Pattern

Question:

Hi, Do you carry a 4 lug rim I can get a radial tire for? I have a small boat trailer U want to take on a long highway trip and may need to upgrade the rims, tires, and even hubs. Thanks

In order to use a radial ply tire on a wheel with a 4 on 4" bolt pattern, you would need to have either 12" or 13" diameter wheels. If you do not have at least a 12" or 13" diameter wheel then you will need to upgrade both the wheel and tire using something like the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel part # AM35351DX which has a 21.3" diameter x 5.7" width. You will need to make sure you have clearance for this size before upgrading.

If you already have a 12" or 13" diameter wheel then you can just add a radial tire to that wheel using the options I have listed for you below. You will need to know your tire size for this part which can be found on the sidewall of the tire. The selection is already filtered by radial ply. For example, if you have ST145/D12 tires on your trailer now then you can use part # AM10140 to replace them with a radial option. If you have ST175/80D13 tires on your trailer now then you can use part # AM10199 to replace them with a radial option.
