Will this mean my odometer reading is 8% higher than it should be? Or my 0-60 is really not 4.9secs? My mpg is really 8% crappier? Seems like its more than just speed that's misinformed...
Pretty sure the odometer is based on the number of rotations of the *rear* wheel.That said, even your odometer is only ever an approximation because it assumes the circumference of your front wheel is fixed and never changes. But we all know the tire circumference changes with wear, temperature, pressure, and different sized tires.
