One of the biggest promises of electric cars is that they will offer relative freedom of constant car maintenance. No more oil and cleaning changes, spark plugs, adjustments, diesel particle traps, diesel exhaust aftertreatment fluid and many other portions to replace. You even have to deal with a silencer clamp.
Well, something funny happened on the way to the happiness of the gas-free vehicle. The last piece that connects the vehicle to the road is a tire, and it flexes. It uses air and wants to be replaced from time to time. That an engine generates traction, load and noise are quite unique if that engine runs quietly. There’s no getting around it: EVs require fast tires for EVs.
How are tires different from electric vehicles?We spoke to several tire brands to find out which ingredients go into the tire oven in the first place and what progress tests they have shown before the tires hit the road.
Yes, traditional internal combustion engine (ICE) car tires will have compatibility with your EV car’s wheels, but this way would be a bad idea. Electric car tires are designed to support the extra weight, dynamic load, and traction needs of an electric vehicle, among other things. Using non-electric vehicle tires is likely to result in much faster wear, heat-related problems, and the possibility of wheels slipping from rest, which, even with traction control, can eventually induce a loss of directional stability.
There are basic differences between ICE cars and electric cars, even before either car moves. Usually, electric cars are heavier than an ICE car of similar length or elegance. For example, the curb weight of the electric Mercedes-Benz EQS 450 4Matic is 5,597 lbs (2539 kg), while the ICE S500 4Matic weighs only 4610 lbs (2091 kg). These cars are not on the same platform, but belong to the same elegance of length and are in the same general segment. The electric vehicle weighs only about 454 kg (1,000 lbs) more due to the undeniable fact that the batteries weigh a lot. The weight challenge will be overcome over time, but in the near future, the basic structure of the car’s housing will need to be up to the task of supporting such a heavy load.
Many other people think that only the rubber compound or polymers of a tire can influence its traction and grip. But in addition to those compounds, the tread design, the intensity of the tread blocks and the vacuum volume between them contribute to great adjustments. in the overall stiffness and load capacity of a tire.
On the positive side of static speed distribution, this prodigious battery weight is slightly distributed, from front to back, in the electric vehicle. However, every positive aspect has a cloud. If this weight were centralized in a much smaller footprint in the middle of the car, it would take advantage of the car’s dynamic mass during braking, cornering, and acceleration. A long, wide battery doesn’t help an EV when it moves and changes direction quickly. And since the car is a moving beast, the dynamic load capacity of the tire will have to be more than up to the task. That means structural stiffness under the 5,597 pounds of this EQS, not only when stationary, but also during braking, cornering and acceleration.
