MIchelin demonstrates how low rolling resistance tires work

Tires get overlooked in the headlines about fuel economy and CAFE standards, which is a little odd. After all, a car's tires are the only contact it has with the road, so more efficient rubber means more efficient use of fuel, and even tiny gains spread over the huge number of road-going vehicles can translate into remarkable overall gains.

Michelin has made a spot that demonstrates the difference its Energy Saver A/S tire can make by staging a downhill drag race. There's a twist, though, and it makes the point beautifully. You can check it out in the video below.
