Your vehicle's front tires typically handle more force than the rear tires, potentially causing them to wear faster and making them less safe as they wear off unevenly. Regular tire rotation can help even out this tread wear, maximizing the life of your tires.
Regular tire rotation helps ensure that all of your tires do some duty while carrying your car around. This helps promote even wear for your tires, and maximum tire mileage for you. Regular tire rotation helps prevent premature tire wear, extending the service life of your tires. In the long run, this could help save you hundreds of dollars in early tire replacement and even on gasoline. Your tires should be rotated based on the vehicle manufacturer's recommended service interval that matches your vehicle's operating conditions and your driving habits or every 6 months / 15,000 miles. Your tires may wear differently depending on their position on the vehicle and the condition of your suspension, and even depending on weather conditions. Make sure they're safe by scheduling tire rotation on a regular basis.
