Must the tire pressures of all four tires be the same?

[Gatsby]

The tire pressures of all four tires on a car do not necessarily have to be identical. Generally, the front two tires will have slightly higher pressure than the rear ones. For example, the front tires might be at 2.4, while the rear tires are at 2.3. Here is some information about tire pressure: 1. The normal tire pressure for most vehicles is around 2.2-2.5, but this is just a reference value. For the exact recommended pressure, you should check your vehicle's user manual or the area near the door (B-pillar or C-pillar), where the manufacturer provides the recommended cold tire pressure. 2. If you notice a significant inconsistency in tire pressure while driving at high speeds, you should pull over as soon as possible. Wait for the tires to cool down naturally. Avoid releasing air or splashing cold water on hot tires. Once the tires have cooled, inspect each one individually.
