What is a sign that tire rotation is needed?

The need for tire rotation is indicated primarily by uneven tire wear. This occurs because different tires wear at different rates depending on their position on the vehicle and driving conditions. Front tires may wear faster than rear tires if the vehicle is front-wheel drive, or if there is an alignment issue. Regularly rotating tires helps to promote even tread wear across all tires, extending their lifespan and improving safety by maintaining optimal performance.

Increased gas mileage is not a sign that tire rotation is needed; in fact, maintaining proper tire pressure and ensuring tires are in good condition can contribute to better fuel efficiency. Improved cornering ability reflects a tire's grip and overall condition but does not indicate that rotation is necessary. Engine overheating is related to cooling system issues, unrelated to tire maintenance or condition. Thus, recognizing uneven tire wear is essential for maintaining overall vehicle health and ensuring optimal tire performance.
