Special tires are used on an EV to reduce rolling resistance. The tires have smaller, and shallower grooves.
Air pressure is also higher than normal tires.
The groove pattern on these tires is also specially constructed to lower rolling resistance and improve performance. With less rolling resistance, the power from the batteries can be used more efficiently to make the car move on the road. With traditional tires, it takes additional power to roll the heavily grooved tires along the ground. As a vehicle moves, the air flows over and around it in a pattern. Some of these patterns work to slow the vehicle by increasing air resistance, while other patterns decrease air resistance.
