Is a tire pressure of 280 too high in summer?

Summer tire pressure of 280 is slightly high, and it can be appropriately reduced. Here is relevant information: 1. Tire pressure range: Cold tire pressure of 2.3, 2.4, or 2.5 bar is normal; after driving for a while, 2.5 or 2.6 is considered normal, but it should not exceed 2.8 bar as high tire pressure. 2. Impact of tire pressure: Higher tire pressure reduces the contact area between the tire and the ground, leading to poor grip, longer braking distance, noticeable bumpiness, and reduced comfort. However, it also results in lower resistance and relatively better fuel efficiency. Slightly lower tire pressure increases the contact area with the ground, improving grip and comfort, but it also increases resistance and fuel consumption. Naturally, tire pressure tends to be higher in summer.
