Wheel Alignment w/ 31" Tires and Lift Kit?

[ivanho]

Well, I have installed a Rough Country 3" suspension lift (w/ all 4 springs) in my '88 Gwag.

I have also put 31"x10.5"x15" tires on her.

From what I have always understood, the alignment specs that an alignment rack computer uses to align your wheels are determined using the original wheel diameter. In my case the wheel diameter has increased by a couple of inches or so. I am not even sure how the lift kit effects the alignment of the vehicle.

I want to get an alignment, but what am I to do? Is there a formula to follow?

It is easy enough to drive the truck and see if she pulls to one side. However, I don't want to go by the stock alginment specs only to find out later that my tires are getting worn out because the stock specs don't apply to my Jeep.

Any ideas?

Follow the alignment specs for an '83 Cherokee Wide-track Chief or Laredo; they came stock with tires about the size you are using.

A better alignment shop should be able to figure out what they're doing, though; lots of people get larger wheels for their trucks and get them aligned. Ask a local 4x4 shop, if you don't have any leads yourself.
