Where ice frozen to the discs is “not accessible”, you will have to remove it with something like a screwdriver. The main thing is to remove the most massive “growths”, since they are the ones that most affect the balance. But all this, as they say, lies on the surface. Much more insidious is the situation when snowfall is not particularly impressive.
In this case, the driver does not pay attention to the wheels at all. Approaching the car, which has been on the street all night, it will brush the snow off her body, start it and drive. On checkers – no attention. In the meantime, if the precipitation falls on the wheels, which are still lukewarm after the journey, they melt there and then freeze. By creating the imbalance described above.
To a greater extent, the rear wheels of cars are prone to such problems. Because the front brakes usually work more intensively and therefore heat up more. At the same time, the ice on the discs also melts more intensively. Meanwhile, the imbalance of the rear wheels, which is less noticeable to the driver, does not touch the steering wheel. But it breaks the suspension. In other words, if your car has been under even a not very intense snowfall, do not be lazy – remove the snow from all rims with a brush and make sure that no ice has formed there. If you find it, make sure to shoot it before the trip. The suspension will be better.
