Why does your electric car need special tyres?

Whether it’s normal wear and tear, a slow air leak, or a sudden puncture, all tires need to be replaced at some point. Which parts to buy is a big decision for any car, but That’s too much for electric vehicles, Its performance and efficiency a major impact on autonomyTherefore, it is advisable to know what characteristics a tire specially designed for electric vehicles should have.

Manufacturers have recently introduced in the market Specialized tires for electric vehicles, These are usually special versions of a brand’s regular tyres, tuned to provide less rolling resistance. These tires are specially designed Heavier, more powerful and quieter vehicles Compared to cars with internal combustion engines. So how does an EV-specific tire differ from a regular tyre?

Electric vehicles require a specific tire as they are designed efficiency considerations. They offer less rolling resistance than normal tyres, which means they create less friction when rolling on the ground and therefore requires less energy to keep movingWhich translates into more autonomy.

There are several factors affecting rolling resistance: air pressure, tire diameter, tread pattern and the rubber itself What are tires made from? It can have all kinds of features; Some compounds create more grip, others wear less over time, and some are better on wet surfaces.

Rolling resistance is affected by several factors: air pressure, rim diameter, tread design, and the rubber the tires are made from.

Tires typically for electric vehicles they wear fastAlthough not always. This is because batteries make them heavier and the extra weight puts more pressure on them, increasing wear. Furthermore, electric motors are also generally more powerful than gasoline engines and generate higher instantaneous torque.

related to noiseIn combustion vehicles, running is partially masked by the sound of the engine. Electric ones, by eliminating these sounds, allow these sounds to be filtered and if the tread of the tires is not designed correctly, this effect will be noticeable in the passenger compartment.

The efficiency of an electric vehicle is more sensitive to change in air pressure, This is because electric vehicles are much heavier than combustion vehicles. Because a flat tire is less rigid and deforms, those mounted on a heavy electric vehicle will deform more for the same pressure loss. Therefore, it is very important for EV owners to check their tire pressure frequently and refill them as per the manufacturer’s recommended pressure.

EV-specific tires cost slightly more than standard tires of the same dimensions and specifications.

Finally, a larger wheel diameter They reduce overall efficiency and hence range. It is an effect that is reflected in the technical specifications of the vehicles themselves: a larger wheel option means less autonomy. This is because they require more energy to get moving, and this is precisely what consumes the most energy when starting from a standstill.

related to price, EV-specific tires cost a bit more than standard tires of the same dimensions and specifications, at least for now. However, it is to be expected that this gap will shrink and even reverse when electric vehicles outnumber combustion vehicles.
