    Can’t get any life out of these trailer tires, what are others running them at for pressure?

    Speed is 105km/hr max. Loaded weight is usually 90% of legal axle group weights, and empty 50% of the time. Been buying the Chinese tires because I am replacing one a week, but maybe I should be buying the brand name tires at 3 times the cost. Super B trailers

    I run mine at the manufacturers minum rating around 100 psi. Don't run the weights probably that you are. Mine is 88,000 5 axles. I run name brand tires and keep everything aligned and balanced yes the trailer tires as well. Made a huge difference in the tire wear.

    Exactly this, also keeping the truck 5th wheel and bridge 5th wheel well lubed is a big part of it. The best bang for the buck tires I’ve seen, for Super B, Dump, Etc Etc have been Firestone or Hankook.

    Thanks, been buying the cheap tires for ~300-400$ but may have to pay for the $900 name brand. Will get alignment at next CVIP. I did the bushings and shocks which helped a bit. Also higher pressure has seem to help as well (120psi). Running the crossfire dual tire equalization system. Maybe as simple as cheap tires being the problem.
