Is It Necessary to Fill Nitrogen in Family Sedans?

[LincolnAnn]

It is not necessary to fill nitrogen in family sedans because the air already contains 78% nitrogen. During the process of filling nitrogen into tires, residual air inside the tires cannot be completely removed. Evacuating the tires to remove this air can damage their internal structure, which is not recommended. Below are the benefits of filling nitrogen in tires: Delays tire rubber aging: The aging of tire rubber is largely due to chemical reactions between oxygen in the air and the rubber and steel rims, leading to tire cracking. Filling nitrogen in tires can significantly reduce the likelihood of irregular tire wear and, compared to air, is less prone to oxidation reactions, thereby delaying the aging of tire rubber. Improves ride comfort: Nitrogen is an inert diatomic gas with lower thermal conductivity than air, so it is less affected by heat. It permeates through the tire walls about 30–40% slower than air. Even when driving at high speeds, it ensures good tire pressure stability, enhancing ride comfort to a certain extent.
