Parse in detail in which cases it is necessary to re-balance the wheels.
For a start — a small educational program. Balancing is the combination of the center of mass of the wheel with the axis of rotation. The cargo is fixed opposite the heavy part of the wheel. This is the definition of static balancing. And since the wheel is not a thin disk, but rather a rink, you need a so-called dynamic balancing when loads are placed on the outer and inner parts of the rim. Of course, the wheels need to be balanced after mounting of the tire on the wheel: because the imbalance can reach 50-60 g on each side. If it turns out more, it makes sense to “twist” the tire relative to the disc, providing them with a mutual rotation of 180 degrees. This initial balancing employees of the tire provide unbalance less than 5 g on the side. It is believed that a new tire is capable of in the first few kilometers to change its position on the disk, and therefore a little balancing will go.
Now let us turn directly to our topic. If you are on the same disks alternately establish then winter, then summer tires, then balancing, you can not avoid. There is nothing to argue about. Question about balancing each season occurs only from those car owners that have two full sets of wheels: summer and winter.
So whether you want to balance the wheels at every seasonal change?
If you approach the process formally, it is necessary to recall the user to the car. It is generally recommended to balance the wheels after driving from 10 thousand to 15 thousand. If you for one season pass is less then balance accurately should not, except as provided below.
But that’s the theory, but in practice, advise and monitor the behavior of the car. If feasible, beating the steering wheel is felt, then balancing is not needed. The runout of the rear wheels is felt less, but usually they suffer less. In any case, a strong imbalance you should feel.
If you do replace the wheels twice a year, then you apply the following recommendation. Put the wheel and train a couple of days. Bus during this time to get rid of the deformations that occurred during storage. If at any speeds at which you drive, there is no vibration, balancing can be prevented.
Balancing is necessary in the following cases:
- you are passing in a season more than 15 thousand kilometers;
- after the last balancing wheel fell at high speed into a deep hole;
- last season you started to mention the vibration, but postponed balancing “for later”;
- if your car has no anti-lock braking system brakes, and you brake often “SW” on the asphalt coating;
- you are a young driver who will not feel the imbalance in the wheels.
