Customers demand quality products. This will be as true in the future as it is today. Each customer wants the best quality and performance products for the intended use. The diversity of tires for racing, aircraft, automotive, trucks, farm vehicles, off-road, and miscellaneous industrial and recreation vehicles amounts to at least 14,500 sizes and types for approximately 6000 different vehicles. Because of new body and suspension system designs, passenger cars now require specialized tires. Generally, this means high performance radial tires and/or all-season types. In many cases, the tires need to be specifically tuned to operate on a given vehicle model. Passenger car tires must also meet a multifaceted set of performance requirements to satisfy the customer.

This multifaceted approach permits a logical expansion of the performance envelope. Expanding the current limits: multifaceted approach. https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780203740378/e47adcd1-1891-4b00-a25c-ac6cdb504b0c/content/fig14_1.tif"/>
