came across this site while looking for tires & wheels for my x. don't know if anyone has already posted this?
you can plug in what larger tires you are going to get along w/ your current gear ratio and it will calculate the change in your speedo, the change in engine rpms with new tires and the new 'Effective' gear ratio with new tire/wheel combination.
its awesome
