Low Rolling Resistance Tires
Low rolling resistance (LRR) tires are specially designed tires that reduce the energy lost as heat when rolling, improving EV efficiency and extending driving range.
Overview
Low rolling resistance tires play a critical role in enhancing the efficiency of electric vehicles. Traditional tires generate resistance due to constant deformation and friction with the road surface, which leads to energy losses. In EVs, where maximizing battery range is a priority, LRR tires are engineered to minimize this energy waste without compromising traction or safety.
By using advanced tread designs, specialized rubber compounds, and optimized sidewall stiffness, these tires help EV manufacturers meet performance and sustainability goals. They are widely adopted in both passenger EVs and commercial fleets, supporting the industry’s pursuit of cleaner, more energy-efficient transportation.
How Does It Work?
The mechanism of low rolling resistance tires lies in reducing the energy required for the tire to maintain motion:
-
Optimized Rubber Compounds: Reduce internal friction, limiting heat build-up.
-
Tread Design: Engineered to minimize deformation while maintaining grip.
-
Sidewall Construction: Reinforced to control flexing, ensuring smoother rolling with less drag.
By lowering the resistance, EVs consume less battery power for the same distance, translating into extended range and improved energy economy.
