The Unexpected Problem With EVs: They 'Tire' Quickly

"Some electric vehicle owners are finding themselves in the market for new tires sooner than they would be with a gas-powered vehicle.

EVs burn through tires 30% faster than combustible engine cars thanks to hefty weights and speedy acceleration, according to Bridgestone, which this week unveiled a new tire developed specifically for electric vehicles. Dubbed the Turanza EV, it starts at $289, depending on tire size. It's now available at Bridgestone retailers in the US and Canada and at sites like TireRack.com."

This is a reply to a commenter who said the article is poorly researched, bc he got 60k miles out of the 30k rated tires on his EV.
(Driver behavior seems to play a factor in tire longevity, for both EVs and ICE cars.)

From Conintental Tires: "Tires for electric vehicles carry a heavier load and have to withstand high instant torque, leading to higher tire wear."

From Hyundai: "The tires of electric vehicles wear 20% faster than those of internal combustion engines, which is due to the acceleration of electric vehicles that generate strong instantaneous power."

From Tire Rack: "The answer might be: 'it depends how you look at it!' As electric vehicles are heavier, due to the battery weight, and as they transfer power to the tires almost instantly, an EV tire will also wear in relation to those factors."

From Michelin: Russell Shepherd, technical communications director for passenger car tires at Michelin:"Electric cars put more torque loads on tires than equivalent gasoline-powered cars for two reasons. First, electric motors make their maximum torque at zero rpm, so when the driver pushes down on the exhilerator (sic), the car leaps ahead. That’s one of the the things people like about electric cars, but it puts stress on the tires. EVs also exert torque in reverse through regenerative braking — the feature that converts kinetic energy back into electricity to be stored in the battery when the car slows down. Any type of braking applies torque on the tires, Shepherd says, but EVs do more of it. They skip the coasting period between acceleration and braking, jumping straight from propulsion to regenerative braking. 'That additional braking does contribute to the faster wear of the tires'."
