Why do ST tires need to run at max psi while auto tires can run at lower than max without problems?
Usually because ST tires are loaded close to their maximum weight allowance and have a lot of sideways scuffing during tight turns with dual axle trailers. Cars, trucks, and single axle trailers don't have that problem.
I would have no problem running auto tires on a single axle trailer and, in fact, do exactly that on my utility trailer and boat trailer. I have been running my travel trailers ST trailer tires at the sidewall maximum for years and have never had a single tire problem.(Knock on wood!)
