I have 33" tires which are about 8% larger than OEM. My speedo registers about 6 mph slower than actual speed - so 65 mph = about 71-72 (according to the radar dispays).
So does my '99's computer read actual speed from a cable in the TC or wheel speed sensors or what? And if the speedo is 8% less than actual does that mead the OH trip computer is reading 8% less than true mpgs?
Thanks, Mike.
