Trailer Tire Recommendation for a 15 Inch Tire Size 7.00 x 15


need replacement 15 inch tire for 7.00 15 14 ply. haul heavy loads up to 14000lbs. any help?

Expert Reply:

The only 7.00 x 15 tire we carry is a light truck tire, # AM10414, that you referenced. The closest size to a 7.00x15 tire would be a 225/75-15. These tires can fit on a 6 to 7 inch wide rim. But they are a little taller at 28.1 inches versus 27.88 for a 7.00x15.

Make sure to use ST trailer tires. The ST in front of the tire sizes indicates Special Trailer. Trailer tires are designed with a thicker side wall to handle more vertical load. An LT is a light truck tire and light truck tires should not be used on trailers.

For a bias ply 225/75-15, you can use # AM1ST96. This tire is rated for 2,540 pounds at 65 psi. If you have a tri-axle trailer (6 wheels total) this tire would work well for you. If you needed a higher capacity, you would have to go to a larger wheel. Trailer tires should always be inflated to the maximum psi listed on the tire to avoid excessive heat build up and failure. I have included a link to our FAQ articles on trailer tires and wheels.
