depends on your driving habits and other factors such as the inflation pressure of your tires, alignment, etc. if you have the continental all-season tires and drive very conservatively, 50,000 miles or more may be possible. likewise, the michelin PS2s can last more than 30,000 miles. if you drive aggressively (hard cornering, acceleration, and braking) you might get only half those figures. otherwise, you'll be somewhere in the middle.
