WHAT'S INSIDE A TIRE?
Modern tire technology blends a unique mix of chemistry, physics and
engineering to give consumers a high degree of comfort, performance,
efficiency, reliability and safety. Many tires are custom-designed to
meet the stresses and performance needs specified by the maker of a
particular model vehicle.
Every tire is carefully inspected, and random samples are pulled for
additional safety tests. As part of these tests, tires are x-rayed, cut
apart and examined, run on test wheels, or road-tested to evaluate
handling, mileage and traction performance.
If
properly cared for, tires can last a long time - usually from 40,000 to
80,000 miles, depending on the application
