Should Tire Pressure Be Reduced at High Altitudes?

[LaChloe]

It is necessary to reduce the tire pressure by 0.2 bar because the atmospheric pressure is lower at high altitudes. If the tire pressure remains unchanged, it effectively increases compared to that on plains. Here is an introduction to tire pressure: 1. Overinflation: When tire pressure is too high, the contact area between the tire and the ground decreases, leading to a significant increase in pressure and wear per unit area. This can easily result in loss of braking control, tire blowouts when encountering road protrusions or depressions, damage to the vehicle's suspension system, and an uncomfortable ride. 2. Underinflation: When tire pressure is too low, the contact area between the tire and the ground increases, causing abnormal temperature rises inside the tire during driving. Additionally, severe deformation of the tire sidewalls accelerates the aging of internal steel wires and fabric layers, increasing the risk of blowouts, higher fuel consumption, and reduced tire lifespan.
