Dug an old Traxxas Cat out of the basement and was going to get it running again. I need some new tires so Iguessed that 2.2" tires would fit the wheels I have on it. That was incorrect. Ilooked on Google to try and figure out my wheel size but I am not sure how to measure it. Anybody know how I can figure out the wheel size of this old buggy and which tires will fit it? Can Iuse these 2.2 tires on it? Should I consider getting some 2.2 wheels and try to run those on the old buggy? Or should I just try to trade these 2.2 tires for something that will fit the existing wheels? Thanks! Mike
