Why do EVs need EV tires?

EVs have a few major factors working against their tires that you don't see as much in their gasoline-powered counterparts.

Ten years ago, you didn’t see many EV tires on the market, but with how popular EVs have become recently, most major tire companies today have found the time has come to start offering their own EV tire products. But why? What’s the point?

Well, it makes sense when you think about it. EVs have two major factors working against their tires: Weight and torque.

You’ll find most EVs are a bit heavier than their gasoline-powered counterparts. Hey, batteries are heavy; the industry’s working on that. But a heavier load translates into faster tire wear.

To compensate for this, tire companies go out of their way to use more robust, stronger building materials to manufacture these tires.

These heavier vehicles typically have more mass than their ICE counterparts as well. More mass means increased inertia, and this translates to a longer braking distance. So, look to the tread and you’ll find tire manufacturers are often concerned about road grip as well in these EV tires.

Next is torque, and in EVs it’s near-instant. More torque means higher tire wear.

As a result, tire manufacturers keep a close eye on the rubber compounds they’re using in these tires, making sure they’re up to snuff. The goal is a smooth, low-impact ride with as little rolling resistance as possible. This not only makes tires longer lasting and more efficient, but also delivers the greatest possible range on a single charge.

Oh yeah, there’s one more issue to worry about in EVs too – noise! Electric cars are very quiet in relation to their gasoline-powered counterparts, so tire noise is going to be extremely obvious to passengers. Talking tires, manufacturers typically revisit tire compounding and construction as well, to deliver the most silent experience possible.

We discuss the challenges related to fleet electrification and why some fleets are turning to microgrid EV charging systems.


Fleet electrification is tricky. Many fleet locations never planned to one day convert their vehicles to run using electric powertrains, and therefore lack the adequate electrical infrastructure to easily make the switch. The good news is that upgrade solutions are typically available, and today there are lots of partners out there who can help fleets get started. The bad news is that the upgrade process can involve lengthy wait times – sometimes up to two years – due to factors like utility management and equipment shortages.
