I understand the Interply shear consideration. Lateral forces across the body and belt created by dragging tire sideways cause very tiny rips between the calendared rubber to fabric and between the layers of fabric.

I brought the tires down to 60 psi.

The reason is that sine I have raised the pressure up from the 55 psi where I had them (When I first purchased the tires ranged from 45-52 psi so I ran them all to 55) to 65 we are seeing small cracks appear in the wood trim of the trailer.

Oklahoma has a lot of black asphalt roads and we can get pretty warm in the summer. Also we have some of the roughest roads around due to clay soil instability.

To me 60 psi is a compromise between maximum tire life (four years at best) and keeping the furniture in the trailer looking it's best.

I do appreciate your input and advice and have taken your opinions into consideration, that's what I did not put the tires back to 55 psi.
