Fuel Efficient Tires & Worn Out Tires

In January 2003, the final report Recommendation for a California State Fuel-Efficient Tire Program was submitted to the California State Legislature and Governor. The report discussed simple factors that have a surprisingly large impact on the fuel efficiency of a tire.

Proper tire pressure. Under inflated tires can reduce fuel economy by as much as 3%. Three percent doesn't sound like much, but over the lifetime of the car it adds up to hundreds of gallons of gas.

Fuel efficient tires. The design of a tire, especially the depth of the tread, and the width of the tire, can have a significant impact on fuel efficiency. Up to 5%. Consumers should compare published rolling resistance reports when comparison shopping for fuel-efficient tires. The tires included with the vehicle when it was new are usally narrow fuel-efficient tires and score low rolling resistance. Car manufactuers include this type of tire so that their EPA MPG is higher.

Have you ever wondered what happens to the 300 million tires that are discarded in the U.S every year. There are dozens of uses. Many are listed here and here .

A San Diego startup, Riverside Technologies , has engineered a process that uses high temperatures to decompose worn-out tires and recover the steel, rubber, oils and a valuable carbon-black material. Gases produced during the process fuel the furnaces used to heat the tires,
