I'll wait for some of the XJ crew to give you a definitive answer, but it does seem like some more information might be helpful... (and potentially increase the effectiveness of responses:confused:)
2" lift manufacturer? Someone might have specific knowledge of the specs of that kit... all end up slightly different...
31's on stock wheels? or aftermarket... what's the backspacing, etc...
manufacturer of the tires? (could lead to personal experience by others, or a general idea of actual diameter based on trends that we may see:confused:)
Hopefully that helps... post up a pic or two... that usually gets the interwebs buzzin'....
