Why do we need two valves on a car wheel

The goals of using a car for a professional racer and an ordinary motorist differ, but the need for safe movement is the same. The health of the wheels affects road safety. And tire manufacturers are constantly improving, bringing new inventions to the market.

On which wheels can two valves be found

In specialized stores, you can find discs on which there are two holes for valves. For example, on disks Kosei, Enkei. They are made in Japan - which is at the forefront in technology. In addition, the inhabitants of the Land of the Rising Sun were famous for the quality of the production of cars, spare parts and accessories for them. The dual valve technology comes from motorsports.

Injection into tires of nitrogen

In motorsport, there is a need to use nitrogen when inflating tires. It contains more molecules than air. And the likelihood of its "leakage" through the pores in the tires is reduced. Nitrogen is less sensitive to temperature rise - it heats up less. Accordingly, handling at high speed becomes better.

Last but not least is the issue of security. Cars often catch fire during races. Nitrogen prevents tires from burning as quickly as air-filled tires. The procedure for filling tires with nitrogen is carried out using two nipples. One is used to remove air from it, the second - to pump nitrogen. They are on opposite sides of the wheel.

Accurate and fast pressure adjustment

For the professional rider, precise and fast pressure adjustments are essential. It is necessary in many disciplines of motor racing. Tires start handling, winning seconds and victories.

Precise adjustment is also important for the amateur motorist. Two built-in nipples allow you to achieve the optimal performance: a pressure gauge is put on one, air is supplied through the second.

Tyrelock installation

Tire disassembly as a result of hitting a pit is a common problem. The solution to the problem can be the use of a tirelock (from the English tirelock: tire - tire, lock - fix). Based on the name, the meaning of using this device is clear - an annular bandage that is put on the disc and is located inside the wheel. In the event of a sudden decrease in tire pressure, such as a puncture, the required level of pressure is maintained. The device has a number of obvious advantages that make life easier for a motorist: controllability in case of a tire puncture, easier balancing, minimizing the likelihood of a tire rupture and disassembly when it hits a pothole, no need to get a spare tire (tirelock will allow you to get to the tire fitting without stopping).

Today, technologies that improve handling and safety when driving a car are developing quite quickly. The owner of the car remains to choose the one that suits his needs and financial capabilities.
