Will 30x9.5 tires fit on stock 15x7 Blazer Rims??? If so how much will it throw off my speed-o??? Biggest tire that will fit are 32 correct??? Or is that with lift, I don't want any rubbing. Sorry if this is a repeat question.
I have 265/75r15s, which are roughly 30.5 " and they rub at full turn with a 2 " body lift.www.1010tires.com has a tire calculator there. If you know your original size tires your all set. I'm pretty sure only the zr2s can handle those tires w/out a b.l. or suspension lift.good luck
