eather you have the wrong size tire or the speedometer driven gear is wrong,or some one has changed the gear ratio in the rear end. these are the only things that could cause your speedo to be off.


Take your car to a dealer who will tell you what speedo gear you should have. The gears are not expensive and easy to change. Should take about 10 minutes including all the jacking of the car. Your axle ratio is coded in the VIN plate.
