Tire rotations are important primarily to enhance traction and extend tire life. When tires are rotated regularly, they wear more evenly. Different positions on the vehicle experience varying amounts of weight and driving conditions, which can lead to uneven wear if the tires are left in one position for too long.

By moving the tires to different locations (such as front to back or side to side), all tires can achieve a more balanced wear pattern. This not only maximizes the lifespan of the tires but also maintains balanced handling and traction across all four tires, which is crucial for safe driving. Proper traction is essential for effective braking, cornering, and overall vehicle stability.

Maintaining tire health through rotation can also lead to improved fuel efficiency, as tires that are in good condition and evenly worn can reduce rolling resistance. However, while enhanced traction and extended tire life are the primary reasons for rotations, benefits such as saving fuel can be seen as secondary advantages of keeping tires in optimal condition.
