A tire is a rubber covering that fits around the wheel of a vehicle, such as a car, bicycle, or truck. It provides traction, allowing the vehicle to grip the road and move safely. Tires are designed to withstand various weather conditions and surfaces, making them essential for driving smoothly and efficiently. Tires come in different types, including all-season, winter, and performance tires, each suited for specific driving needs. They are filled with air to maintain their shape and provide cushioning. Regular maintenance, like checking tire pressure and tread depth, is important for safety and prolonging the life of the tires.
