I run 50 psi in all my tires as well, no issues to date. I have a buddy that inflates his F-250 tires to 80 psi to gain economy, and those tires will last him close to 50k according to his experience. Mind you we're talking about 12 ply rated tires, but it's suprising the number of myths you see debunked here.
