Cars | Why do electric cars wear tires so much? “The same thing happened when diesel cars started to become more common”

Electric cars often wear tires faster than internal combustion cars, but the main cause of wear is not propulsion.

A a representative of the car tire trade recently smiled that electric cars have done good for the business. They when wear tires faster than internal combustion cars.

Tire manufacturer Goodyear agrees. It has developed its own tire for electric cars “to meet the unique requirements of this growing segment”.

Goodyearin according to tests electric cars consume tires up to 30 percent more faintly than internal combustion cars.

On the other hand, Nokian Tires’ Development Manager Mikko Liukkula told Tuulilasi a couple of years ago that faster tire consumption for electric cars would be a fallacy.

His according to him in fact, the opposite is true, as modern all-electric cars, he says, have so much better traction control systems than internal combustion engines.

Car Tire Association Chairman of the Board Jarmo Nuora, do electric cars wear tires faster than internal combustion cars?

“So true or false? True in part, but the reason is not unambiguous, ”Nuora says.

In principle, an electric car is heavier than an internal combustion engine due to its battery, which means that the tires are subjected to more forces when starting, stopping and cornering. This eats tires.

“But there have been big-mass cars for ages and ages, and the tire manufacturer makes a tire according to the mass of the car.”

The problem is not so much with the weight as with how the driver moves that weight.

The high weight combined with the wild torque is the poison to the tires.

Cars sold by power but driven by torque, an old saying goes.

Even if an internal combustion engine car has a lot of power, maximum power is often only available in a narrow, high rev range.

Because in normal traffic, driving is mostly at lower revs, a high-performance car can feel heavy to move if it has no torque. Good torque allows the car to accelerate quickly even at lower revs: there is no need to put a smaller gear in the eye when overtaking.

Electric cars have an electric motor where a wild amount of torque is available immediately and all the time: with the speed ranges no need to be adjusted. Also in electric-assisted cars, i.e., hybrid cars and rechargeable hybrid cars, acceleration is usually rapid because the electric motor assists the internal combustion engine in accelerations.

Many people think that the funniest side of electric cars is this all-time torque, so drivers like to accelerate their electric cars from traffic lights or in overtaking situations.

Large weight combined with wild torque is poison to tires. An extreme example of this is, for example, the Tesla Model X, which weighs 2,500 pounds and accelerates from zero to one hundred at best in three seconds.

“You don’t even have to pedal that car particularly hard, but the extra wear can come pretty unnoticed,” Nuora says.

“It was the same thing when [yleensä bensiiniautoja paremmin vääntävät] diesel cars began to become more common. People wondered how the tires would wear, even though they reportedly drove really neatly. ”

So it’s not so much a question of transmission or propulsion, but how a new kind of propulsion can almost unnoticed change a driver’s driving style.

If the tires of his electric car have to be replaced frequently, it can be scary, as the tires of electric cars are often relatively expensive, according to Nuora.

Cord says that especially with new studded tires, you should accelerate especially carefully.

“New studded tires should always be run in, ie 500-1,000 kilometers are driven particularly nicely. This way, the pins last much better. ”
