Low-rolling resistance tires
From Wikipedia, the free encyclopedia
Low-rolling resistance tires are tires which are designed to improve fuel efficiency of a car (particularly hybrids) by minimizing the energy wasted as heat as the tire rolls down the road.
[edit] Aspects
Most of the hybrid vehicles use some sort of low rolling resistance tires.
- 80% or more of a car’s fuel energy is wasted by friction and other such losses.
- 1.5 to 4.5% of total gasoline use could be saved if all replacement tires in use had low rolling resistance.
- About 237 million replacement tires are sold in the U.S. each year – none have rolling resistance labeling.
