Re: tire size

Welcome to the site!!

I would think on a 2wd a 31 would be about all you can do, if you go with a 33 then you would have to do some kind of lift to make that work.

Hope that helps,
Trav

Re: tire size

I have 33s on my blazer. All i had to do was Cut the back bottom lip off of the outer fender about 4 inches up using a cut-off. I have had absolutly no problems with this set up. Now if your going to be doing hard core mudding i dont recommend 33s without a lift. the inner fenders need no modifications. Just be sure to put a rust prohibitor on that fresh steel.
