Tire pressure of 2.8 bar is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. 2.8 bar is higher than the maximum value of the standard tire pressure, so it is not normal. Winter and summer tire pressure standards: Tire pressure should be based on the standard tire pressure of the car tires, and can be appropriately increased by about 0.2 bar in winter. In summer, it can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Whether the tire pressure is normal can be judged by the tire pressure monitoring light: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during driving, and it alerts the driver to tire leaks and low pressure to ensure driving safety. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, with an exclamation mark inside. The tire pressure monitoring indicator light indicates abnormal tire pressure.

I think 2.8 bar tire pressure might be a bit high, it depends on what car you drive. Generally, the recommended tire pressure for family sedans is between 2.2 to 2.5 bar. If it's too high, the tires will wear unevenly with the center part wearing out faster, which not only shortens tire lifespan but also increases fuel consumption. Safety-wise, excessive tire pressure makes the car bounce more and reduces traction, especially when cornering in rainy conditions, increasing the risk of skidding. I suggest checking the label on your door frame or owner's manual immediately to find the standard value for your specific model, then measure it with a tire pressure gauge. If it's too high, release some air to adjust it. Get into the habit of checking tire pressure monthly - the most accurate reading is taken when the tires are cold. Be extra careful in summer as high temperatures naturally increase tire pressure, which can be troublesome if it exceeds the limit.

I've experienced issues with tire pressure being too high, and 2.8 bar is definitely inappropriate. For most vehicles like SUVs or sedans, the standard tire pressure is around 2.3 bar. Setting it to 2.8 bar makes the tires feel like balloons, resulting in a stiff and bumpy ride. Driving like this for a long time also accelerates tire wear, increasing the cost of tire replacement. I've also noticed that it consumes extra fuel—higher rolling resistance can burn an additional 0.5 liters per 100 kilometers. To save money and hassle, it's best to use a digital tire pressure gauge for measurement, as it's more accurate than the free ones at auto repair shops. Remember to check when the tires are cold. If you're inexperienced with a new car, check the manual first—don't blindly follow gas station air pumps, as they often set the pressure too high. Maintaining the right tire pressure ensures both safety and extends vehicle lifespan.

A tire pressure of 2.8 bar is slightly high. The standard value for common car models usually ranges from 2.2 to 2.5 bar. For example, my car is calibrated at 2.4 bar, so I set it there. If the pressure is too high, the ride becomes noticeably bumpy, significantly reducing comfort, especially on rough roads where it feels like riding a roller coaster. It also affects the tire's contact area with the road, making it more prone to slipping in rainy conditions. It's recommended to check the door label for the correct value and adjust it using a tire pressure tool. If you lower it, you'll likely feel more stability after driving for a few days.
