Q: Why is tire rotation so important?
A: Each tire on a vehicle performs a different task, causing them to wear at different rates. Regular tire rotation allows tires to wear evenly, maximizing tire life and allowing tires to be replaced in sets of four, which is preferable.
Q: Why is tire pressure important?
A: Improperly inflated tires are a leading cause of tire failure. Proper tire pressure helps a tire have optimum tread contact with the road, which improves traction and braking and reduces tire wear. Underinflated tires generate heat, which is the tire’s worst enemy, so maintaining the right amount of air keeps temperatures where they should be.
Q: How will I know when I need new tires?
A: You’ll need new tires when the tread wear indicators—called wear bars—appear. These wear bars look like narrow strips of smooth rubber across the tread and appear when it’s time to replace your tires. If you can see three or more tread wear indicators, you should replace your tires. Other ways to know when to replace your tires include cord or fabric showing through the rubber, cracks or cuts in the tread or sidewall deep enough to show cord or fabric, bulges or splits in the tire, and punctures or damage that cannot be repaired correctly.
