A tire is a crucial component of a vehicle, serving as the interface between the car and the road. Constructed from layers of rubber, fabric, and steel, tires are designed to provide traction, stability, and support for the weight of the vehicle. They come in various types and sizes, tailored to different driving conditions and vehicle requirements, including passenger cars, trucks, and specialized vehicles.

The primary function of a tire is to provide grip on the road surface, allowing for safe acceleration, braking, and cornering. The tread pattern on the tire plays a significant role in this aspect, as it is engineered to channel water away, reducing the risk of hydroplaning and enhancing traction in wet conditions. Tires are also designed to absorb shocks from bumps and irregularities in the road, contributing to a smoother ride for passengers.

Tires are categorized into various types such as all-season, winter, and performance tires, each optimized for specific driving conditions. Regular maintenance, including checking air pressure and tread depth, is essential for tire longevity and vehicle safety. Additionally, tire technology has evolved significantly, with advancements in materials and design improving fuel efficiency, reducing road noise, and enhancing performance. Overall, tires are integral to vehicle safety and performance, influencing everything from handling to fuel economy.
