Optimal air pressure

-> low rolling resistance

maximum EV battery range

The batteries that power electric vehicles weigh more than gas-powered engines. This added weight bears heavily on the tires, creating greater friction between the road and the tire, or rolling resistance. A tire’s rolling resistance is critical to energy efficiency as more friction creates a power drain on the batteries and an increase in the tire internal temperature, resulting in high energy consumption and decreased vehicle range.

Maintaining optimal air pressure reduces rolling resistance and helps your EV to maximize the full potential of its battery range.

Good air retention means low Inflation Pressure Loss Rate (IPLR), which measures the percentage of air loss per month and varies widely depending on the composition and gauge of the tire innerliners. The lower, the better. Low IPLR can minimize the “in-use” rolling resistance and maximize the EV driving range. Tires with Exxpro™ 3563 based innerliners can even improve battery range from 3 to 7%.
