Electric cars are generally considered environmentally friendly, but the high acceleration often leads to sprints. But even without intention, the high torque of the electric drive for a higher tire wear.
Who has driven a lot with a Stromer, it will probably have noticed already: The car tires are used up faster and it will therefore
Because of the high starting torque, the tires can even wear up to twice as fast.
According to tire manufacturer Michelin, tires are only half as long when used on electric cars as is the case with burners. The reason is quite simple: Due to the higher torque, the narrow tires of the wheels are subjected to a higher load.
Therefore, they should be swapped according to the manufacturer's recommendation about every 25,000 kilometers.
If you pay attention to the range of the electric car, you should buy special tires
The test tested Goodyear EfficientGrip Performance, Nokian Weatherproof all-weather tire and Nankang Noble Sport NS-20. The test vehicle was the 204 hp electric car Opel Ampera-e.
According to TÜV, the Goodyear tire scored best in the test.
The Nankang and the Nokian caused by their higher rolling resistance that one with a fully loaded electric car Opel Ampera -e theoretically 19 or even 34 kilometers earlier to head for a charging station.
Thomas Salzinger (Tire Team Leader at TÜV SÜD) says:
"Tire manufacturers are currently working on the development of special models for electric cars. You have to have because of the higher weight of the vehicles a suitably designed load capacity and at the same time cope with the strong torque when starting and accelerating. "
The TÜV therefore recommends to pay attention to the lowest possible rolling resistance when buying tires in the EU tire label.
The testers said:
"If, for reasons of economy, recourse is made to all-season tires or particularly favorable alternative products, this saving can, in addition to certain safety-relevant deficits and high rolling resistance in the electric car, clearly go at the expense of reach."
"The 60 kWh batteries would not have been sufficient for the usual tests. That's why we replaced our timed laps on the 3.3-kilometer dry handling course with a 162-meter slalom. "
The experts from TÜV SÜD have also dealt intensively with the range of coverage in their own laboratories. "For all three candidates, we carried out extensive rolling resistance measurements in advance in our test laboratory in Garching near Munich", adds the tire expert. The results of the measurements with a test load of 552 kilograms, a tire pressure of 2.5 bar and a constant speed of 80 kilometers per hour: Goodyear: 41.3 N rolling resistance force (= coefficient cR 7.6 kg / t) Nankang 45.5 N (cR 8.4 kg / t). Nokian, the all-weather tire, rolls the hardest with its year-round profile: 48.9 N (cR 9.0 kg / t).
For the sake of the environment, high-tech tires with a lower rolling resistance should be bought, as this avoids unnecessary tire consumption.
That means with the right tire set you can have fun with your electric car and at the same time be eco-friendly mobile.
