I don't think so.
A taller tire is in effect raising the gear ratio, therefore the axles and
driveshaft turn slower. Going to a taller gear does the same thing.
The sensor measures pulses on the axle or driveshaft depending on the speed
they turn, right? Lower gear, axles, driveshaft and engine spin faster gor a
given speed, therefore more pulses, higher speedo reading.
Correct me if I'm mistaken.
