Best Answer

There are different sized gears that install in the transmission to fix your problem. Follow the speedometer cable down to the transmission. Unscrew it. There will be one bolt that holds the gear in place. Remove it and take out the entire unit. Different gears are different colors. You'll probably have to experiment to figure out which one you need. Some parts stores and most dealers carry these gears.

How does tire size affect the speedometer in a car?

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.
