I have a 2003 ZR2 it appears to me to already have a 2" lift with it already.
What would be the max size tires that I can mount with the factory wheels?
It already has 31.5 X 15 tires mounted looking to put on a new set.
Thanks!

 

same size tires if it sits at stock height

 

You should really know whether you have a 2" body lift on it or not before asking "what size tires". Very easy to tell. If you don't know how to tell just ask up and we'll let you know.

 

unless u put a minimum 4" lift on it ul be pressed to run 31s only.

 

You might want to stick with 31's unless you want your speedometer to be off. You might be able to run 32's but they'll probably rub the fenders when turning if you hit a bump. Then you'll have some nice gashes in your tread and that doesn't look good on brand new tires.

 

What I am hearing is "Stay with what you have".
Thank you everyone.

 

for sure, thats a nice looking blazer rob44_90. and for akron red neck, sticking to ur size u have will give u less of a headache then if u were to go one size bigger, which u wouldnt tell a huge difference in anyway.

 

Thanks man, it's been my project for the past couple of years. Your blazer's badass, I wish I had a SFA and 40" tires!!

 

I'm still amazed you don't have a clue if you have a lift or not. Bigger tires mean more ground clearance.

I'm gonna guess you don't worry about going offroad and more of how pretty you look in the local shopping mall.

Yes, this post was a bit mean spirited but no offense meant.
