Low-rolling Resistance Tires
Low rolling resistance tires minimize wasted energy as a tire rolls, thereby decreasing required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency. Approximately 5–15% of the fuel consumed by a typical car may be used to overcome rolling resistance. A 2003 California Energy Commission (CEC) preliminary study estimated that adoption of low-rolling resistance tires could save 1.5–4.5% of all gasoline consumption, but that current data were also insufficient to compare safety and other characteristics. A database of much more complete data will be released by the CEC pending completion of an ongoing study.

Famous quotes containing the words resistance and/or tires:
“High treason, when it is resistance to tyranny here below, has its origin in, and is first committed by, the power that makes and forever re-creates man.”
—Henry David Thoreau (1817–1862)
“Sickness disgusts us with death, and we wish to get well, which is a way of wishing to live. But weakness and suffering, with manifold bodily woes, soon discourage the invalid from trying to regain ground: he tires of those respites which are but snares, of that faltering strength, those ardors cut short, and that perpetual lying in wait for the next attack.”
—Marguerite Yourcenar (1903–1987)
