OK, I have found the webpage and have seen the numbers. How can the average trucker determine what fuel savings can be obtained by these numbers. For example, I have 8 Bridgestone M726EL drive tires on my truck with a rolling resistance of 141. I am looking at a rib tire with a resistance of 102. Can anyone explain to me what I would save in fuel to change tires. The bridgestones are still very new (2/32" worn from new of 32/32"). I bought the tires before I learned about the possibilities of fuel savings with a lower rolling resistance. Thanks in advance to all who reply...Geoff
