I'm new to this forum stuff and don't know if I'm putting this question in the right place but here goes: Does anyone know how to reset the speedo on a 2010 XB so it will work correctly with the bigger tires I put on mine? I went from the stock 205/55/16 to 215/70/15 and they are 2" bigger in diameter. Rides better and looks better (to me) but when the speedo reads 60 I'm actually doing 65. Anybody?
