The difference between electric car tires and regular ones


As if it wasn’t already difficult enough to choose a set of car tires, the landscape became significantly more complicated after electric cars became popular. Here is the difference between electric car tires and regular ones and why it is not good to confuse them.

There are considerable differences between electric cars and those with internal combustion engines. Therefore, it is natural that their components are also different. Among the most important, but also the most disregarded, are the tires. They are responsible for both the performance of a car and the safety of traffic, through the way they transmit engine power to the ground and the way they ensure the steering and braking of the car.

Electric cars have several characteristics that make them fundamentally different from those with combustion, at least in terms of tires. For example, electric cars are significantly heavier at similar sizes due to batteries. Volkswagen ID.3, a compact model, weighs somewhere between 1.7 and 1.9 tons, while a Golf with similar characteristics is much lighter – between 1.2 and 1.5 tons.

The difference between electric car tires and regular ones is huge

Hence the need to strengthen the tires for electric cars so that they can better cope with higher braking and steering forces. In particular, the sidewall of the tire is much stiffer, so that a tire intended for electric cars deforms less in corners. In this way it ensures a superior targeting accuracy.

Also due to the large mass of electric machines, aquaplaning is much lower when passing through water holes. Because of this, the channels that ensure water drainage are narrower, which promotes adhesion on dry roads, but also efficiency. In turn, this is a key feature of an electric car, so the tires for them have a low rolling resistance.

Another feature of electric cars is given by the character of the electric motor – it has a huge torque at low speeds. The demands of the running gear are thus much more intense, and the tires must ensure both high durability and superior grip.

Lately, driving noise is much more annoying for an electric car, especially at city speeds (30-50 km / h). This is because the engine noise is insignificant and the wind noise becomes noticeable only at higher speeds. Therefore, tires for electric cars have a layer of sound-absorbing foam inside. Lately, however, sound-absorbing treatment is also available on some models of tires for combustion cars.

Why it’s not good to confuse tires

Therefore, it is not a good idea to mount a regular tire on an electric car. If you do this, your car’s handling will suffer, as will your autonomy. In addition, it will wear out faster and provide diminished performance.

But what if we try the exact opposite – to mount a tire for electric cars on a car with a heat engine? This is not a good idea either. Apart from the fact that it will cost unjustifiably a lot, it will not offer significant advantages, but only disadvantages.

Thus, the performance of aquaplaning will deteriorate significantly – the low mass of the machine and narrow drainage channels will make the machine aquaplaning at much lower speeds, with dramatic consequences on safety. In addition, the higher stiffness of the flank will affect the level of grip in corners. The only advantage – low rolling noise – can also be found on a tire for combustion cars, if you opt for a model with sound-absorbing foam.
