At this time we do not carry a load range E 15 inch trailer tire to replace the tires on your trailer.

The ST225/75R15 trailer tires we carry, item # AM10256, have a capacity of 2,540 lbs at 65 psi, and should be sufficient for the axle and components on your trailer. Going to a higher capacity tire could possibly make other components on the the weakest link and subject to fail.

One tip we can offer, if you are experiencing premature tire wear or blow outs, is to check the weight of your trailer to be sure that it is not over capacity when loaded and ready to tow, and to run the maximum psi rating stated on the side of your ST (special trailer) tires. Running lower than max pressure on trailer tires can cause the tires thicker sidewalls to heat up and reduce the service life of the tire.
