What type of valve is used for inflating car tires?

[DiClaire]

Car tires are inflated using a valve. Below is relevant information about tires: 1. Main materials of tires: The primary material of tires is rubber, which has the characteristic of aging after prolonged use or storage. This leads to significant changes in the tire's physical properties such as hardness and wear resistance. Continued use of aged tires may lightly affect vehicle performance or, in severe cases, result in a tire blowout. 2. Tire lifespan: Generally, all-season or economy tires have a lifespan of 3-5 years or approximately 50,000 kilometers. Under normal conditions, tires are sufficiently usable for one year after leaving the factory. However, high-performance tires have a much shorter lifespan of only 20,000-30,000 kilometers. If the price is reduced, purchasing them may also be considered.
