I have a 2002 blazer zr2, curious if i can fit 33s on it without modifying ? i have a good deal on tires and rims and hope to make it happen. if i cant what modifications would i need to make?

 

Could you have a local tire shop do a test fit for you? They did that for me when I was choosing betwen 30s and 31s.

 

I had 31s on my Gen1. 31x105R15LT. Loved it.
Have held off on getting that again because my present truck looks and rides so well, but..
33s *might* rub a little ?

 

10.5 or 12.5 wide? On a zr2 should only need a 2" body to clear with out trimming.
