FWIW, I replaced my Rainiers after a month and 1000miles. No issues, just did not want any issues. Goodyear Endurance tires have been on since then. I have heard that Maxxis are pretty good but I have never owned them. Endurance and Maxxis are the only brands I'd consider for my current trailer.
My tire pressures cold are 80psi (max load pressure). When on the highway they go up to 90 and sometimes over. Not had a problem with them. Follow mfg instructions. The tire is not designed to run at the cold pressure, it is designed to run at the 'hot' pressure. That is why the mfg warns you NOT to reduce the pressure of a 'hot' tire. Some mfgs may have other inflation instructions for extreme conditions, ie, ambient temps over 100F. Check with them.
