With my Blazer being the Zr2, what is the biggest size tire I can fit without lifting it? I need new tires and I would like to get 33s but I don't want to do a lift right away if possible. I'm sorry if this sounds like a dumb question, I'm not much of a vehicle person but at least I'm trying lol.

 

31" is stock, and probably the biggest without a body or suspension lift. You might run into rubbing on fenders and/or frame if any bigger.
Of course I have a "normy" 4 door LS, so not being super familiar, I could be wrong.

 

Here's a thread I just stumbled into about Zr2 tire sizes..
