On the topic of tires, what's the best kind. I heard we should all use an RV rated radial on the trailers. This guy said they have a heavier sidewall and the tire has very little side to side sway. The light truck tires are heavier duty than the car tires but not the same sidewall thickness as the RV tires.

I was told somewhat the opposite by my tire dealer. that the Mich XCA 7.00X15 (standard equip on our '77 new) had a stiffer sidewall than the 235/70R15ST (special trailering) I've been told that the ST just denotes an anti UV additive in the compound.....
