2wd tucking 31s
 

I wanted to know if I could tuck 31s on my 2001 chevy blazer 2wd with stock rims till I have the money to get a body lift?

Quick answer: No. Not without rubbing.

Some people have been able to do it without any major modifications, but most people rub seriously on the back of the front fender, as well as the top of the wheel well when flexing the suspension. If you go with an all-season tire rather than an AT or MT tire you might be a little more lucky since regular all-season tires don't have the heavy squared shoulders.

If you really want bigger tires on a factory suspension I'd suggest looking at a set of 255/70/15's. They are wider and look a lot meatier than the stock 235's, but you can fit them without any lift at all.
