You say by 10% my mileage may be off? How does that compensate for the exact mileage i got before the tires then? help me out here
i use those "speed clockers" all the time. i just drive by, at the posted speed (say 30) when it tells me my speed, i check my speedo again. even with my 32's i'm always dead on. before, with the 31's i was always 3 mph slower than what the police clocker said. so, if my speedo read 30 mph, i was really doing 27mph. (when i had the 31's)
