wheels and rims
 

what is the biggest size tires i can get on an 01 blazer with stock suspension? i was thinking 17s.

Tires or rims? I'm sure you can do 17s, just have to have a smaller sidewall.

Theres about a million threads on what size tire you can fit. I want to say a 30" tire is the tallest on stock suspension

I had to remove my mud flaps, and small torsion crank for 30". I have since done a 2.5 lift and going to 31s in summer.

but for the rims all I look for is clearance to disk brakes, and overall tire diameter 30". After that you want to check clearance on depth of tires and rims, so they dont rub your control arms...
