Extend Your Tire Life
With an average treadwear rating of 610, these are long-lasting tires. Proper maintenance can push them well past their expected mileage.
- Check tire pressure monthly and before long trips — underinflation is the leading cause of tire failure
- Rotate tires every 5,000-7,500 miles to ensure even wear
- Get a wheel alignment check annually and after hitting major potholes
- Inspect tread depth regularly — replace at 4/32 inch for wet weather safety
- Avoid rapid acceleration, hard braking, and sharp turns which accelerate wear
- Store seasonal tires in a cool, dry place away from direct sunlight and ozone sources
