The reality is that it depends on many factors. The national average is 3 – 5 years. The life of your tires will vary based on the type of vehicle and most importantly your driving habits. As your grandfather probably told you speeding, hard braking and hard acceleration will prematurely wear your tires. Other major factors are stop and go local driving versus extended highway driving. To maximize the life of your tires make sure to regularly set the pressure, rotate your tires and check the wheel alignment.
