If you like bus will lose pressure, then insert in the form of a ring that is mounted on the drive to assume the weight of the machine.
The apparent advantage of additional support is recognized that there is a drive carrier. After all, this disc should not be changed because it is not subject to wear. In this case, and bus will not need to be replaced, and will not deteriorate because of reduced load on it.
We should also say that the use of additional support significantly improves the quality of the car. This is due to the fact that the tire walls have similar figures for the rigidity of traditional tires.
