Low rolling resistance tire

Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance. Such tires are now commonly installed as standard, either mandated by law or to meet eco labelling standards.
