325/60/20

I have a 1999 GMC Yukon (old body style) and wanted to upgrade to 325/60/20 tires, the same size as the H2. I was wondering how much of a body lift i will need to get to fit the 35 inch tires.

I think you would only need about 2 inches, the tires give a bit of their own natural lift.

I would guess that 2" isn't enough. It might be worth asking this question on chevytruckworld.com as well. I'm definitely no expert, but folks there are going with 4" - 6" lifts for tires of this diameter.

Take care,
Jerry
