Why does everyone in the tire shop have to check the tire nipples?

Soon the “rubber” season change will come and there will be long queues at the services. In this fever, many drivers will ignore the little things that seem completely unimportant at first glance. For example, the condition of the wheel valves. But they can cause a lot of trouble for the motorist. About all the “pitfalls” the portal “AvtoVzglyad” tells.

Expensive tires and wheels that motorists select for a long time and carefully study tests. But they pay no attention to penny nipples, since they are eternal. This is far from the truth. The rubber used in their construction is not oil and gasoline resistant. Chemical residues on asphalt and spilled technical fluids significantly shorten the life of components. The rubber housing shrinks and ages. Therefore, over time, cracks and even small hernias form. In the spring, as speeds increase, the load on the tires also increases. As a result, air begins to poison from the “orifice” on the valve. So the pressure can drop to zero. In this case, the pump will not help and you will have to put a spare wheel.

And the valves differ in length and size of the hole in the wheel. The deeper it is relative to the outside of the rim, the longer this valve should be. Here comes another danger. Long parts can be crushed, bent or damaged during storage. The result is the same as described above. After installation of the wheel, it begins to descend. Looking ahead, let’s say that a large “air channel” can be easily torn off even in the mud. It also increases the imbalance of the wheels.

A motorist who decides to buy a brand new ‘rubber’ in the spring can also run into problems. When replacing tires, the professionals will also update the valves. Here are only the cheapest. Although they are fresh, they do not last long, especially if the driver likes to accelerate. The fact is that when the wheel rotates at high speed, centrifugal forces act on the parts. They deform the “nipple” to the side. Thus, the rubber seal between it and the disc gradually wears out. The result – the new band begins to “poison”.

Therefore, fit good quality nipples with an anodised housing and petrol resistant rubber. Overpay 1000 rubles, but save yourself a lot of trouble in the spring and summer.
