I was curious if anyone knew what tool/scanner you would need in order to adjust the wheel size in the speedo I dropped down to 235/45/17 and dont want to rack up more miles than i actually am.
when i had a jeep you could buy a little scan tool that just punched in the tire size and it adjusted the speedo. Does anything like that exist for the focus st?
