Sorry to revive this old thread, but I recieved my 31x10.50 OTR Muds today and they look great. The myth that retreads are taller than new tires of the same size is bogus, each one measured dead-on at 31". I "under ordered" with the 31's because they were supposed to measure 33" tall! Oh well, maybe I'll just bite the bullet and throw down for a set of real 33's some day...
