trailer tires

Look for tires with a cap ply (or more than one!) Cap plies will be in the tire description on the sidewall - as in Tread: 2 plies Polyester, 2 steel and 2 nylon. The nylon = cap plies. Sometimes it is called polyamide.

I don't ever think I will buy a nylon capped tire again. My old types were 2+2+1 and they were the typical using polyester and nylon, the new tires I got are 2+2+2 but labeled all steel belted radial so no Polly or nylon belts. I was reading this has something to do with the side stresses put on a multi axel unit's tires when doing tight turns, but I can seem to find that article again. I had one blow out last summer and when I went to replace it this spring, I found two others that were rounded across the top of the tread so that indicates they were separating. 4 brand new tires this year with hopefully better construction.
