I am going to get new tires and I am going with 33X12.50/R15 and I want to got with a 15X10 wheel but I don't know what the proper off-set is? With the lift that I am running which is the Man-A-Free 4+ shackle reversal kit. So I would like to run a off-set wheel that will still allow me to tuck the tires into the wheel wells without rubbing. I am running a 15X8 wheel now. I don't think that I can run the 33X12.50/R15 on a 15x8 without running the risk of popping a bead. So any help or thoughts on this would be nice thanks.
