Need help with my trail tech

[Woodsrider]

Being the nice guy that I am, I was helping a friend get his wifes trail tech set up and inadvertantly cleared all the data out of mine:mad: To make matters worse I lost the instruction sheet that had my tire size written on it.
Is any one out there using a endurance computer with the stock size tires on their 400? I need the proper wheel size to put in.ANy one want to help me out?
