Warum verwenden Autos keine größeren Reifen, um das Fahrgestell höher zu machen?

At present in the domestic sales of various types of models, the chassis of the ground clearance are generally in the 100-250mm, depending on the model, while the car ground clearance is generally in the 100-150mm.

Car owners change tires in three directions: change the size, change the thickness, modification and upgrade. Although this big action into a lot of money, sounds forced also quite high, but once the change is not good, the car’s performance is not only not improved, but will pull you back!

So, why is the chassis of the car so low? Is it feasible for us to improve the chassis height of the car by changing the larger wheels? Today we will talk to you about this matter.
The important purpose of lowering the chassis of the car is that, by lowering the center of gravity of the vehicle, increase the downward pressure of the body, improve grip, so that the car in the process of high-speed driving, can get better handling stability, so the world’s supercars are almost lying on the ground running

Why don’t cars use bigger tires to make the chassis higher?

Of course the lower the chassis, it means that the vehicle’s passability is not good.
But some of our current so-called SUVs are actually still essentially sedan chassis, just by increasing the ground clearance height to get better passability. This is because SUVs and cars, like the load-bearing body, its chassis can not withstand high-intensity off-road, only through some technical changes in the suspension, improve ground clearance, to achieve the purpose of passing the general bad road.

Sedan as a family car, the first element is the comfort and filtering, because it daily driving conditions are mostly paved roads (city roads), so the high chassis for the car, and not much practicality. Moreover, the lower the chassis, the more stable the center of gravity, which is visible through the ground clearance of the supercar, only the car to consider the actual practicality, so it can not be completely set in accordance with the standards of the supercar.

The height of the vehicle chassis, at the beginning of the car design and factory, are calculated and tuned, basically after the limit of the environment and road testing, in addition, the height of the vehicle chassis is determined by the suspension and weight, even if you change the car into the largest tires in the same class, without changing the suspension, the height of the body will still not change significantly, so by replacing the large size of the tires, can not increase the chassis The ground clearance.
Why not use bigger tires on the sedan to make the chassis higher?

Of course it is perfectly feasible to use larger wheels on a sedan. But it is obvious that the chassis of the car with big wheels is still very low.
The reason for the car with large wheels is simply to increase the contact area between the car and the ground, making the braking performance improved and more stable cornering.
