Tires for e-cars: lower rolling resistance increases range
tires for electric cars
What range gain is possible with this? “If the rolling resistance value is reduced by 1 kg/t, we expect a range gain of three to four percent,” says Burkhard Wies, Head of Development at Continental.
Robust treads against premature tire wear on e-cars
Electric car weight requires high load capacity tires
Electric cars weigh around 200 to 300 kilograms more than comparable combustion engines. Your tires therefore need a higher load capacity. When buying tyres, it is therefore essential to pay attention to the correct load index: It is in Part I of the registration certificate or can be requested from the vehicle dealer.
Low tire rolling noise for more driving comfort in the e-car
Because the electric motor is quieter than a combustion engine, tire noises inside the vehicle are more noticeable in the electric car. Low-noise running surfaces are therefore an important factor for driving comfort.
Vibrations in the tire cavity, which are transmitted to the vehicle interior, play a particularly important role in noise development.
Safety despite the low rolling resistance of e-car tires
Can a tire that is optimized for rolling resistance also be top when it comes to safety? “From a technical point of view, there is a difference between low rolling resistance and optimal Grip a conflict of goals,” explains Burkhard Wies. “When developing tires, a good compromise must be reached between the two properties, which is very successful thanks to advances in rubber compounds.”
