What does low rolling resistance tire mean?

[DakotaAnn]

Low rolling resistance tires are fuel-saving tires, generally improved by altering tread grooves and adding silica. Below is relevant information about tires: 1. Functions of tires: Mainly include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load capacity, handling performance, average wear, and mileage. 2. Tire cross-section structure: Can be roughly divided into 4 parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to provide sealing. 3. Internal composition of tires: The interior of a tire is composed of multiple layers of different materials, including tread pattern, overlay, steel belt layer, stress absorption rubber strip, carcass ply layer, and inner liner.
