Tread Depth was the standard for Tire Life. When the Tire Tread was Low then you needed New Tires. Today, Tires are mostly made of Rubber. Rubber starts to Degrade as soon as the Tire is Manufactured. At about 5 years the Rubber in the Tire Degrades at a faster Rate. Even if you Store the Tire in a Temperature controlled Room, the Tire is Degrading. Make sure you check the Age of brand new Tires. Heat, Cold, Sun and Ice can increase the Degrading Process. Most Car and Tire Manufacturers recommend replacing Tires every 6 Years. The National Highway Traffic Safety Administration has said that an average of 90 people are killed and 3,200 are injured in the US every year in Crashes involving Old Tires. In 2013, Paul Walker was killed while Driving a Porsche Carrera GT with 9-year-old Tires. These 9 year Old Tires compromised their Drivability and Handling characteristics.
