Why it's necessary to monitor the cleanliness of the disk

Often, you can come across complaints about vibration and noise from tires, but in the vast majority of cases, the cause of discomfort is not the tires themselves. Even if the defect appeared after their replacement. Today, we'll look at the most common cause of vibration that can occur after tire mounting.

The reason, of course, can be many factors. It can be the disk, the condition of the suspension elements, and the cleanliness of the hub. Yes, it's precisely this moment that many people don't pay attention to. This is often encountered when the buyer decides to change the wheels themselves. In this case, neither balancing nor valve replacement is done, and, of course, the hub and the disk's mating area are not cleaned. After which, noticeable vibrations appear on the steering wheel. The conclusion, more often than not, is the same - the tires are defective.

The cleanliness of the hub and the disk's mating area is extremely important. That's why these elements are never painted, even in factory conditions. Any, even the slightest, deviation of 0.5 mm can lead to the fact that the wheel cannot be balanced. That's why the contact areas of the hub and disk are ideally machined.

What can be seen when changing wheels? Dirt and rust literally crumble, getting between these elements. Moreover, the higher the wheel's mounting diameter, the greater the vibrations will be. That's why, during professional tire mounting, they will clean both the disk and the hub and apply copper grease to prevent "sticking".
