The Race to Create the Perfect EV Tire
With billions sold each year, the battle is on to make the ideal electric car tire—one that offers the holy trinity of increased range, eco credentials and less noise. The results could benefit every vehicle on the planet.
In 1845, somewhere between inventing a system for detonating explosives by electricity and the refillable fountain pen, Robert Thomson, a Scottish engineer and entrepreneur, patented the first pneumatic tire—a then wondrous, now everyday item that has been gradually evolving ever since. Michelin argues that its figure of 20 percent more tire wear in EVs comes from their extra weight, greater motor torque, and the way regeneration tends to reduce the amount of coasting. The competition between manufacturers to improve their tires is so fierce that during motor races where teams use different brands, companies scour the track after the event looking for rubber fragments.
