How does tire size affect the speedometer in a car?

Cars & Vehicles

The speedometer in a car runs based off the speed of the transmission. The gears in the transmission spin at a known rate for the speed the vehicle is traveling at. The faster the gears spin the more the speedometer goes up. If a person replaces stock tires with larger tires, then the tires will spin slower, which will cause the speedometer to read at a value that is less than the actual speed.

Does changing wheel size affect speedometer?

Altered Tire Size Since there is more surface area and a larger circumference on the outside edge of the tire, the wheels will actually spin slower at any given speed than the stock setup would.Therefore, the speedometer in the vehicle will read less than the actual speed that is being traveled.
