I'm putting a 3 inch lift on her,wanting to know what size tire I can run?

 

I'm running 33-10:50 15's on my 96 ZJ with a 3 inch lift.

 

Without trimming anything you can safely run a 31-10.50-15 with a three inch lift.

 

I didn't have to do much trimming to run 33's. Just a little at the bottom of the front fenders. Had 31's on it first but I love how I it looks with the 33's That's why I went with 10:50's. They're a little narrower for less clearance issues.
