Speedometer accurate with 32's?
If my Tacoma came stock with 31's and I go up to 32's on stock 15x7" rims, will my speedometer/odometer still be accurate? Just wondering what other's experiences are.

Since my switch i have been the same...whenever i pass one of those standing radar's it seems to be dead on and when the cop gave me a ticket it was also dead on unfortunately...I wish i could get it to where it was slow by a % or 2 so i would be doing 50 thinking i was at 52 or so...i doubt you'll see a difference.

3.8% is what I measured with almost full tread Revos.
Speed read through ODBII vs. GPS readout. Speedos of course differ from car to car but the ODO should be getting the math right through the computer.
31.9" REVO / 30.7" OEM = 3.9% (theoretical number, so leads me to believe the computer and sensors were calibrated very good at the factory for OEM tires)

This is a great site for seeing what the differences in size will do to the accuracy of your speedo.
