According to https://www.bgr.com/2135498/why-ev-tires-wear-out-faster-gas-cars-explained/, tires on electric vehicles tend to wear faster than those on comparable gas-powered cars, and three root causes explain most of it: added weight, instant torque, and efficiency-focused tires.
Battery packs add serious mass. EVs are commonly 20 to 50 percent heavier than their internal combustion counterparts, which increases the load the tires must carry during acceleration, braking, and cornering. A clear example is the Chevy Equinox EV, which tips the scales at about 4,923 pounds compared with 3,428 pounds for the gasoline version. More weight means greater contact pressure and faster abrasion, especially on the driven axle and the outer shoulders of the tread.
Then there is the way electric power is delivered. Electric motors produce maximum torque from zero RPM, so acceleration can be abrupt and instantaneous. That immediate twist and scrub puts more mechanical stress on rubber than the more gradual torque curve of a gasoline engine. The result is faster wear, particularly on front- or rear-driven tires depending on the layout.
Tire design aimed at extending range also plays a role. Low-rolling-resistance tires are standard equipment on many EVs to squeeze more miles from a charge. Those tires often use softer compounds and specialized tread geometry that cut energy loss but trade off long-term durability. Tire makers, including Michelin, estimate EV tires last about 20 percent less on average, which puts typical replacement windows near 30,000 to 40,000 miles versus roughly 40,000 to 50,000 miles for gas cars. High-performance electric models tend to wear even faster.
Regenerative braking changes braking dynamics too, and that can add stress. Regeneration shifts some braking load from the pads to the drivetrain and tires, and the different heat and force patterns can accelerate wear in ways drivers may not expect.
Tire engineers and manufacturers are responding. EV-specific tires are built with stiffer sidewalls, reinforced structures, and tougher compounds to resist flexing and reduce heat buildup under the heavier loads. Those design changes improve longevity without giving up too much efficiency.
Drivers can do a lot to slow the pace of wear. Keep tires inflated to the recommended pressure, accelerate and brake smoothly, maintain proper alignment, and rotate tires regularly every 5,000 to 8,000 miles. Avoid overloading the vehicle. Those habits can push replacement out and narrow the gap with conventional cars.
Costs matter. Replacing a full set of EV tires can add up, commonly ranging from about $1,000 to $2,000 per replacement depending on size and specification. Good maintenance and choosing EV-capable tires can help lower that ongoing expense.
As more EVs hit the road, tire technology will keep evolving to meet electric demands, and longevity should improve as automakers and tire makers fine-tune compounds and constructions for heavy, high-torque cars.
