What is the appropriate tire pressure for high-altitude areas?

[AlexisRose]

High-altitude car tire pressure should be between 2.3~2.5. The following is relevant knowledge about car tires: Functions of tires: Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness; maintaining excellent adhesion between wheels and road surfaces; improving traction, braking, and off-road capability; and bearing the weight of the vehicle. The crucial role tires play in automobiles is increasingly being recognized. Classification of tires: Full-size spare tire: A full-size spare tire has exactly the same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary replacement, limited to non-driven wheels, and with a maximum speed not exceeding 80km/h.
