Thanks for the replies. Since they prorated three of the four Goodyear tires on the rear. and the other has 15k miles I plan to run them for awhile. I'm aware Westlake tires aren't supposed to be a top tier tire,but so far they have out perform supposedly better brand tires. The rims and size are stock and I have around an inch between the duals when loaded. Temperature and psi is monitored with a TST system. The BFG separated on the front first,then two later on the rear. The wranglers were only on the rear, since the front were nearly new..... Buzzcut1 I thought about a spacer between the rears. Could your provide the type your using?? Thanks to all and anymore thoughts appreciated.
