Okay so im finally pulling the trigger and going with a bigger lift from ORD plan is to get a 6 or 8in lift currently my main question is I have 15x12 mickey thompson classic 3's with a backspace of 3.6in offest of -73. What is roughly the biggest tire I can go with a 6 or 8in lift I been doing some research but i figured you guys would know best. Its mainly street drive I do mud it a decent and trail it a bit but nothing super serious
