Tire makers are being asked to pull their weight when it comes to cutting energy use, the Wall Street Journal reports. As much as 20 percent of the energy needed to operate a car is tire-related, according to some industry estimates. Cars with tires that have a lower rolling resistance use less energy.
The EU is expected to propose regulations that would set limits on tire rolling resistance. Other areas of the globe could follow
Western and Japanese tire makers want standards for rolling resistance - as well as labels that would grade tires on energy efficiency - which could give them an edge against tire makers from India and China, which tend to spend less on R&D.
France’s Michelin SA has been touting the fuel-saving potential of its “green tires.”

“As much as 20 percent of the energy needed to operate a car is tire-related, according to some industry estimates.” - yet more flawed statistics in use by the Environ-mental lobby. Perhaps at a constant speed of 20kph, on a level surface, this figure is accurate, but it is ludicrous to assume that 20% applies in normal stop/start operating conditions, when the number is going to be more like 1-2%. Address the real problem - reduce the congestion which causes stop/start conditions. And do it by better traffic flow management NOT by reducing available road space in a vain attempt to get people out of their cars.
