  • Should I consider installing a run flat tire?

    Run-flat tires are standard on 12 percent of new vehicles and while the number of vehicles available with run-flat tires has tripled in the last decade, they seem to have hit a plateau. There are a variety of tires using run-flat technology today and it’s helpful to understand the difference before installing.

  • Do I need to replace out of round brake rotors?

    It’s not necessarily required that you replace your brake rotors at the same time you replace your brake pads, or if they are considered out of round brake rotors but there are many reasons why it’s highly recommended.

    The main problem is that your rotors are most likely grooved, and putting fresh pads on grooved rotors is going to wear the pads faster. Using those grooved brake rotors could also cause your wheels to wobble once you add new brake pads.
