Question:

How fast down the freeway can this tire handle before falling apart? Say at half load weight and 12 hrs, at 80mph, in 90 deg fahrenheit heat. Can it handle that? Or 75 mph? Or 70 mph?

Expert Reply:

The Kenda tire # AM1ST92 is now rated for 81 miles per hour regardless of the load on them. Running it over that speed for extended periods of time can cause excessive heat build up and lead to tire failure.

Another option in the same size, 205/75-15, that has the same 81 miles per hour speed rating is # TTWTRTM2057515C. It is a radial tire so it will run cooler than a bias ply tire.

Provided the rest of the trailer is in good shape and won't cause uneven tire wear you can run these tires at a higher speed for extended periods of time. I would stay under 80 though for safety.
