2. Truck Tire Rolling Resistance

3. Truck Tire Rolling Resistance Testing Method

4. Tire Factors (Rolling Resistance) The less rolling resistance a tire creates, the better the fuel economy. Look at the affect these tire components have on rolling resistance. As you can see, 60% of the fuel efficiency gains result from the tire’s tread. The less rolling resistance a tire creates, the better the fuel economy.

15. Tire companies that are approved Partners: 14 New tire manufacturers Over 90 tires and growing SmartWay™ classifies Partners as entities that commit to direct emissions reductions and fuel savings. I.e Fleets Goodyear would be classified as a SmartWay™ Affiliate

16. What qualifies a tire to become SmartWay approved? By wheel position: Steer / Drive / Trailer Retreads approval expected Q3 2011 Open shoulder drive tires under review EPA has established rolling resistance values by wheel position that companies must meet Rolling resistance coefficient Values will be continually reduced over time i.e 2014
