Tire replacement is the process of removing old or worn-out tires from a vehicle and installing new ones. This is essential for maintaining safety and performance, as tires provide traction and stability on the road. Signs that tires need replacement include visible wear, cracks, or low tread depth. When replacing tires, it's important to choose the right type for your vehicle, considering factors like size, tread pattern, and driving conditions. Regularly checking tire pressure and alignment can also extend the life of your tires. Proper tire maintenance ensures a smoother and safer driving experience.
