i ran 32x11.5 maxxis on my hilux for 4 years on 7" sunnies.Never hada problem,it looked good and i used to air them down to about 15psi.
I now run 33x12.5 maxxis on it on 8" rims tho.
my zook is on 15x8s with 31x10.5 and i run old cheap hankook muddies,i dunno if the tyres are the problem of if its the 8s,but i have done numerous amounts of beads out wheeling going down to about 10psi.have done a few at full pressure too
