Tire Pressure and Speedometer Calibration
Curious question:
In a new build vehicle, what pressure are the tires maintained at for calibration, or at least verification of correct operation of, the vehicle speedometer -
the maximum cold pressure according to tire sidewall, or, vehicle manufacturer OEM specified cold tire pressure?
The reason I ask is because if I drive, IE, 56mph in the right lane of a 55mph zoned highway, other drivers are either zooming up to my trunk, or, warping by me in the lanes to my left. My tires are kept at, or at 1psi above, cold pressure specified on the vehicle OEM door pillar decal.
