What is the purpose of tire rotation?

[MacJoel]

The purpose of tire rotation is to achieve even tire wear, extend tire service life, prevent abnormal tire wear, and improve driving safety. The methods for tire rotation are: 1. For bias-ply tires, swap the tires on the same axle to ensure even wear on both sides; 2. For radial tires, rotate them within the same side of the vehicle. Tire maintenance methods include: 1. Maintain correct tire pressure; 2. Regularly inspect tires for bulges, cracks, cuts, punctures, and abnormal wear; 3. Check the tire surface for stones, nails, or other hard objects and clean them promptly; 4. Perform four-wheel rotation.
