Is a tire pressure of 280 too high in summer?
2 Answers
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.
I have been driving for many years and encountered tire pressure issues quite a few times during summer. A tire pressure of 280 kPa is indeed too high on hot days. The recommended tire pressure for most vehicles is between 220 and 250 kPa when the tires are cold, and it naturally increases as the temperature rises. For example, at 30°C outdoors, the tire pressure might be about 20 kPa higher than when cold. Starting at 280 kPa means the initial pressure is too high. Excessive tire pressure causes rapid wear in the center of the tire, reduces grip, and increases the risk of skidding, especially during sharp turns or on slippery roads, raising the chance of accidents. I recommend checking the sticker on the door frame or fuel cap for the manufacturer's recommended value. Measure the tire pressure with a gauge when the car is cold in the morning, and if it exceeds the range, let some air out appropriately. Regular maintenance can save a lot on tire costs. Summer is a high-risk period for accidents, so don’t take it lightly—develop a habit of quarterly checks for safety and peace of mind.
