Alright, I'm going to be buying new wheels/tires. I'm looking at the MT-28's in 15x8 but I want to be sure that the 15" wheel will work with my brakes. Also want to be sure the tires I plan on putting on (33" Duratracs) won't rub. So the combo I'm looking at is:

Mickey Thompson MT-28's and 33" Duratracs

The specs on the MT-28s are:

Backspacing- 3.75"
Offset- (-)19.00mm

Should this work with no problem? Not familiar with offset and backspacing....Thanks.

EDIT: I have a spare set of 15x7" factory rims, could I put 33" KM2's with a 10.50 width on those rims?
