This may seem a dumb question, but how does a speedometer actually work?
If the speed of the car is calibrated by the speed which the axle turns, then do manufacturers adjust the setting of the car if you swap from say 18” to 20” wheels.
For example, 18” wheels will be (in simple terms) moving you forward by 54” for one complete revolution.
20” wheels by 60”. Therefore, the % difference is not insignificant, especially if going past speed cameras. (Not been flashed, just curious for those mechanically minded).
