Car tires

Pneumatic tires are manufactured in about 450 tire factories around the world. Over one billion tires are manufactured annually, making the tire industry a major consumer of natural rubber. In 2015 alone, 1.72 billion tires are expected to be sold globally.Tire production starts with bulk raw materials such as rubber, carbon black, and chemicals and produces numerous specialized components that are assembled and cured. Many kinds of rubber are used, the most common being styrene-butadiene copolymer. This article describes the components assembled to make a tire, the various materials used, the manufacturing processes and machinery, and the overall business model.Treads are often designed to meet specific product marketing positions. High performance tires have small void ratios to provide more rubber in contact with the road for higher traction, but may be compounded with softer rubber that provides better traction, but wears quickly. Mud and snow (M&S) tires are designed with higher void ratios to channel away rain and mud, while providing better gripping performance. Specialized tires will always work better than general/all purpose/all weather tires when being used in the conditions the specialized tires are designed for.
