One of the biggest promises of electric vehicles is that they provide relative freedom from constant car maintenance. Gone are oil and filter changes, spark plugs, tune-ups, diesel particulate traps, diesel exhaust aftertreatment fluid, and countless other parts to replace. There’s not even so much as a muffler clamp to deal with.

Well, a funny thing happened on the way to petrol-free motoring bliss. The final piece connecting the car to the road is still a tire, and it still flexes. It uses air and needs to be replaced every so often. And the demands a motor places on traction, load, and noise are quite unique if that motor whirs silently. There’s no way around it: EVs require EV-specific tires.

How are tires for EVs different? We spoke to several tire companies to better understand what ingredients go into the tire oven in the first place and what development testing has proven before the tires hit the street.
