SAE article with Geely Auto: Tire pressure impact on EV driving range

Electric-vehicle development teams have made great advances in improving vehicle range, mitigating "range anxiety" for the end customer. While much focus has been on advances in battery technology, controls and vehicle aerodynamics, electric-vehicle (EV) driving range also is significantly affected by tires. Tires lose a certain amount of air on a continuous basis. Energy-inefficient tire construction, sub-optimal inflation and other factors can adversely impact EV range.

A new study shows that tighter control of tire-pressure loss can lead to marked improvement in electric-vehicle efficiency.
