Car wheels are circular components that allow vehicles to move smoothly on roads. They are typically made of metal or alloy and are fitted with rubber tires, which provide traction and absorb shocks from the road surface. Each wheel is connected to the car's suspension system, which helps maintain stability and comfort while driving. The size and design of car wheels can vary significantly, affecting the vehicle's performance and appearance. Larger wheels can enhance handling and aesthetics, while smaller wheels may improve fuel efficiency. Proper maintenance, including regular tire rotations and pressure checks, is essential for ensuring safety and longevity of the wheels and tires.
