Why is the tire pressure of new cars set very high?

[StAmelia]

New cars generally have high tire pressure because they are often parked outdoors for uncertain durations. Insufficient tire pressure can cause tire damage. To prevent irreversible deformation (out-of-roundness) and loss of wheel dynamic balance during prolonged parking, new cars are delivered with higher tire pressure. It is recommended that owners check the tire pressure when picking up the car to avoid compromising driving safety. Additional relevant information is as follows: 1. Both car manufacturers and tire manufacturers provide clear recommendations for standard tire pressure. The specific values are usually indicated on a label inside the fuel filler cap or on the B-pillar of the car body (visible when the door is opened). Generally, tire pressure ranges between 2.2-2.5 bar. Some also specify the spare tire pressure, which is slightly higher, around 2.8-3.5 bar. 2. The most significant risk factor for tire blowouts is tire damage itself, often caused by overdue service or wear exceeding the limit.
