Low Rolling Resistance Tires

Tom MurphyEnergy Technology & Policy

December 6, 2007

Rolling Resistance

Car engine must overcome rolling friction to propel the vehicle forward — this requires fuel consumption

Rolling Friction Force:

frr NCF

Type of Tire Crr

Ordinary Tire ~0.015

Typical LRR Tire <0.0105

Best LRR Tire ~0.006

Normal Force (vehicle weight)Rolling Resistance

Facts About Tires

Vehicle manufacturers usually install

LRR tires on new vehicles to help meet

CAFÉ standards more easily

Most replacement tires are not LRR

~237 million replacements sold each year

None are labeled with any indication of their

rolling resistance coefficients

Benefits

A 10% decrease in Crr can decrease fuel consumption by 1-2%

California Energy Commission estimates total gasoline use can be reduced 1.5-4.5% if all tires in use were LRR

This can be safely implemented with current technology
