As used in recycling, passenger car and truck tires (excludes airplane, bus, motorcycle and special service military, agricultural, off-the-road and-slow speed industrial tires). Car and truck tires are recycled into rubber products such as trash cans, storage containers, rubberized asphalt or used whole for playground and reef construction.
Critical parts of your car that allow braking, accelerating, and cornering on wet or dry roads and contribute significantly to the vehicle's ride quality. All cars today use radial construction tires. Sidewalls are usually reinforced with polyester or nylon. Treads are reinforced with a combination of polyester, steel, and sometimes nylon.
Many different types of tires are used, depending on the class or the area in which you are running. Manufacturer and tire stickyness are typically mandated by the governing body of your race. You can get a nice overview of the different degrees of stickyness (as determined by their compound) on KAM's tire page. The stickyer a tire, the softer it is, which in turn results in a higher tire grip which allows higher cornering speed. Harder tires do not provide as much grip as stickyer tires, but they will last longer (several races), compared to a really soft tire (one race). Harder tires are typically used in the novice classes. A tire is mounted on the wheel rim.
the solid rubber or air-filled rubber/synthetic part of the wheel that makes contact with the floor.
