Re: How to change tire size?
pick the tune, then select the option to modify the tune, then go to tire size or axle ratio and you'll see a revs per mile setting to adjust for your tires.
make the change, then go back until it asks if you wish to install the tune, and choose yes.

Re: How to change tire size?
I know this is a dumb question, but in figuring Tire revs per mile, I know you use tire height, but do you use actual tire height or round up or down if your tire height is, say, 33.5 inches?
