Question:

My trailer came with ST225/75R15 inch tires on a 5 on 4.5 wheel. I am looking to acquire two spare tires and want the highest load I can get. What do you have that will work?

For spare wheels/tires in your tire size ST225/75-15 with your 5-on-4-1/2 bolt pattern you can refer to the page I linked for you. This displays all wheel/tire items that match your requirements and these are offered in Load Range ratings C and D.

We have both bias ply and radial type tires in your size. Naturally you want to match your tire size but you also want to use the same type of tire too. For higher-speed highway driving radials are preferred for their greater flex and traction; bias ply tires are preferred for driving off-road where their stiffer sidewalls will do a better job on those rough roads. In general radials will be better able to handle higher speeds.

For a Load Range D tire and white wheel you might consider the Kenda # AM3S862. The Kenda # AM3S862 can handle up to 2150-lbs and speeds up to 81-mph.

No matter which particular tires you use on your trailer ALWAYS inflate them to the maximum psi pressure noted on the tire sidewall; observe their rated weight capacity; and stay within their rated speed to ensure the longest lifespan.
