So you are talking about running 12.5" tires on a 12" rim?That's 1/4 th inch overhang on each side.... I really don't think you're gonna blow the bead off unless you are running 5 psi or less.Ask your guy @ the tire shop & see what he thinks. We don't have sand to run in where I'm located so maybe this is a biased opinion. <img src="/forums/images/graemlins/cyclops.gif" alt="" />
