Tires...

We just put new tires on our 2014 Forest River Wildwood DBUD. They are “radial” tires with 65 psi cold max and a “D” load rating. Two questions...first question, do we need to under inflate these tires like we did the bias ply that were on it before? Second question, do we need to periodically rotate the tires on our travel trailer like we do on our car/truck? Thanks in advance for any input!!!

I stopped rotating tires over 30 years ago. If you have a tire or tires wearing then you have a problem. It could be alignment, suspension problem, balancing or the tire itself has a problem, which needs to be corrected. Rotating tires in these cases just treats a symptom and not a cause. Since I first owned my first car in the '60s I have never purposely underinflated a tire. I have always run the recommended air pressure for the load. I also have my TV alignment checked once a year. I average about 67K miles on a set of tires.

My 2¢.

Unless you have an all wheel drive vehicle it's still a good idea to rotate tires. Tires under torque will wear differently than tires that are merely passive as they roll down the highway.

On travel trailers alignment issues are often not easy to remediate and different wear patterns can emerge due to how the suspension behaves when loaded. Unless wear is excessive rotation can often coax a lot more miles out of a set of tires than just letting them keep wearing in the same position.

I haven't had my new trailer long so I haven't seen how the tires will wear on the torsion axles versus the leaf spring/equalizer type suspension on my old trailer. I rotated tires on the old setup every time I pulled the drums to check brakes and lube the bearings. Did it help? Don't know but since the wheels were off it was no big deal.
