Tyres on electric or hybrid vehicles play an important role in performance and efficiency. For manufacturers, it is a new challenge as it is necessary to adapt tyre manufacturing to their future uses. The weight of the batteries and rolling resistance are important parameters that need to be taken into account when manufacturing EV tyres.
What is the difference between tyres for electric vehicles and traditional tyres?
We are often asked if there are differences between EV tyres and conventional tyres. The answer is YES, EV tyres are specially designed for electric or hybrid cars.
Tyres for electric vehicles take into account the weight of the batteries, the difference in torque, and rolling resistance to offer a better experience to the end user.
One of the first tyres developed for electric cars is the Michelin e.Primacy. Thanks to its good management of rolling resistance, this profile offers 7% more range, which is about 30 km for a vehicle with a range of 400 km.
Goodyear recently introduced a tyre called Goodyear ElectricDrive GT, specially designed to be used as a replacement tyre on electric cars. This high-performance all-season tyre offers an improved tread, designed to be both durable and optimised to ensure a quieter ride. This new Goodyear tyre is specifically adapted to the unique requirements of electric cars and aims to offer an optimal driving experience in terms of performance, longevity, and acoustic comfort.
Continental with its AllSeasonContact 2, Bridgestone with its Ecopia EP500, and Hankook with its IonEvo also offer profiles with European EV certification.
However, it is entirely possible to fit a conventional tyre on your electric car and vice versa.
Is it possible to repair an EV tyre?
Yes, just like a conventional tyre, it is possible to repair the tyre with a plug. As with a conventional tyre, for the damage to be repairable, it must be located on the tread. In case of damage to the sidewall, the tyres are not repairable. In any case, it is important to consult a professional.
What tyres are originally fitted on Tesla cars?
Several profiles are used by Tesla as original equipment:
- Michelin Pilot Sport 4S
- Continental ProContact RX
- Hankook Ventus S1 Evo3
- Pirelli Winter Sottozero 3
- Michelin PS Cup 2
- Michelin Primacy MXM4
Depending on the rim size chosen at the initial order, the tyre will be one of these models.
You will notice that some of these tyre profiles are also fitted to conventional vehicles as original equipment.
Do tyres for electric vehicles wear out faster than conventional tyres?
With equivalent use, tyres for electric and hybrid cars do not wear out faster than tyres for conventional cars. Some drivers may have this impression in case of dynamic driving. The weight of the vehicle and the high torque available on electric cars can put a strain on the tyre rubber.
What is the average lifespan of tyres for electric vehicles?
The lifespan of a tyre for an electric vehicle can vary depending on its use. Generally, the lifespan of a tyre for an electric vehicle is the same as for a conventional vehicle, i.e., 30,000 to 60,000 kilometres.
To maximise the lifespan of your electric car tyres, regularly check the tyre pressure and favour smooth starts.
Are retreaded tyres suitable for electric vehicles?
Yes, you can use retreaded tyres on your electric car. All conventional car tyres are compatible with electric cars.
Are tyres for electric vehicles more expensive than conventional tyres?
No, overall, for the same size, a tyre for an electric car will cost you the same as a tyre for a conventional car.
Are there any specific recommendations for maintaining tyres on electric vehicles?
No, the rules are the same as for a conventional tyre.
Regular pressure checks (at each change of season) or before each long trip, along with a visual inspection of the tread and sidewalls of the tyre. If you are approaching the wear indicator, it is time to change your tyres. By following these simple tips, you will maximise the lifespan of your tyres. Regular tyre maintenance is crucial to ensure optimal performance of electric cars.
