Did a search but came up blank. How do you change the tire size in a XRT once you have it installed? Do you have to reload the program ( and if so, how)? I do not see any options other than changing the tune level. My speedo is showing 10 mph higher than my GPS. Any help appreciated. Thanks

Got it. Reloaded program, returned to stock size on tire selection. It is pretty close now.
