you can try some bead locking adhesive that mud trucks run in order to keep a bead attatched..... i would try a little more air. im runnning the BFG 205-50-15 drag radial and i keep about 30+ psi in them and they are treating me right.

also, im gonna go 10s with stock axles................just cause im a cheap bastard! but i doubt 9s are in the near future, keep kickin ass RON
