What is the appropriate tire pressure for entering Tibet?

There is no need for any special gas; regular air will suffice. The normal tire pressure for cars generally ranges between 2.2 and 2.5 bar. However, car tire pressure is not fixed and should be adjusted appropriately based on factors such as season, load capacity, and driving routes. Standard tire pressure can usually be found in the following places: the vehicle's user manual, the label near the driver's door (close to the B-pillar), or the drawer next to the driver's seat. Additional relevant information is as follows: 1. Overinflated tires: This reduces the contact area between the tire and the ground, leading to a significant increase in pressure and wear per unit area. It can easily result in loss of braking control, blowouts when encountering bumps or potholes, damage to the vehicle's suspension system, and discomfort during rides. 2. Underinflated tires: This increases the contact area between the tire and the ground, causing abnormal temperature rises inside the tire while driving. Additionally, severe deformation of the tire sidewalls accelerates the aging of the steel cord layers, increasing the risk of blowouts, higher fuel consumption, and reduced tire lifespan.
Driving into Tibet really requires attention to tire pressure, as a buddy who frequently travels this route, I gotta remind you. The high altitude means atmospheric pressure is much lower than on the plains, causing tires to naturally expand after inflation, increasing tire pressure. Before departure, it's advisable to set the pressure 0.1 to 0.3 bar lower than standard – for example, my car's cold standard is 2.4 bar, so I adjust it to 2.3 bar for Tibet. The road conditions in Tibet are poor with huge temperature differences, freezing at night and scorching during the day. Excessive tire pressure increases the risk of blowouts, especially when bouncing on gravel roads. Measure tire pressure with a gauge when the tires are cold for accuracy, not when hot. Check frequently on the road and consider carrying a portable air pump for easy adjustments. Tire condition determines safety, so don't forget to ensure even tire wear overall. It's best to get a comprehensive check at a 4S shop before heading to Tibet.
