275/60R20 tires should work.

 

Wow, 20 year old post awoke from the ashes..Stock tire height tire is really close to 30". A 295/40/20 will put you at 29.25" on a 20x10 rim. You will need to to do the steering stop mod. Grind off the back side of the steering stop and install 1/2 hardware to make adjustable steering stops. The alignment tech can adjust them during of after the alignment. When going to a 10" wide rim it will want to scrape the inside of the rim on the brake line bracket to the LCA.
