A tire (American English) or tyre (British English) is a ring-shaped vehicle component that covers the wheel's rim to protect it and enable better vehicle performance. Most tires, such as those for automobiles and bicycles, provide traction between the vehicle and the road while providing a flexible cushion that absorbs shock.
The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal that fitted around wooden wheels to prevent wear and tear. Early rubber tires were solid (not pneumatic). Today, the majority of tires are pneumatic inflatable structures, comprising a doughnut-shaped body of cords and wires encased in rubber and generally filled with compressed air to form an inflatable cushion. Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are still used on locomotives and railcars, and solid rubber (or other polymer) tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.
Tyre (Arabic: صور, Ṣūr; Phoenician: 𐤑𐤅𐤓, Ṣur; Hebrew: צוֹר, Tzor; Tiberian Hebrewצר, Ṣōr; Akkadian: 𒋗𒊒, Ṣurru; Greek: Τύρος, Týros; Turkish:Sur; Latin:Tyrus, Armenian Տիր [Dir]), sometimes romanized as Sour, is a city in the South Governorate of Lebanon. There were approximately 117,000 inhabitants in 2003. However, the government of Lebanon has released only rough estimates of population numbers since 1932, so an accurate statistical accounting is not possible. Tyre juts out from the coast of the Mediterranean and is located about 80km (50mi) south of Beirut. The name of the city means "rock" after the rocky formation on which the town was originally built. The adjective for Tyre is Tyrian, and the inhabitants are Tyrians.
Tyre is an ancient Phoenician city and the legendary birthplace of Europa and Elissa (Dido). Today it is the fourth largest city in Lebanon and houses one of the nation's major ports. Tourism is a major industry. The city has a number of ancient sites, including its Roman Hippodrome which was added to UNESCO's list of World Heritage Sites in 1979.
