Tires (or 'tyres' in British English) are ring-shaped parts, either pneumatic or solid, that fit around wheels to protect them and enhance their function. The fundamental materials of modern tires are rubber and fabric along with other compound chemicals. Their constructive make-up consists of the tread and the body. The tread provides traction while the body ensures support.
The basic purpose of a tire is to enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.
Before rubber was invented, the first versions of tires were simply bands of metal that fit around wooden wheels in order to prevent wear and tear. The word itself is derived from the word "attire", referring to the dressing of the wheel. The most recent and popular type of tire is “pneumatic”, pertaining to a fitted rubber based ring that is used as an inflatable cushion and generally filled with compressed air. Pneumatic tires are used on many types of vehicles, such as bicycles, motorcycles, cars, trucks, earthmovers, and aircraft.
