Can I still drive on the highway with a tire pressure of 2.8?
2 Answers
A tire pressure of 2.8 or 2.9 is relatively high. Driving on the highway under such conditions can easily lead to tire blowouts, increased braking distance, and other braking issues, which are very dangerous. Therefore, it is not recommended to drive on the highway. It is advisable to visit a repair shop for inspection and ensure the tire pressure is normal before driving on the highway. Winter and summer tire pressure standards: Tire pressure should follow the standard tire pressure of the car's tires as a principle. In winter, it is appropriate to increase the pressure by about 0.2 bar. 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 automatically checks the tire pressure in real-time while driving and alerts the driver to tire leaks or low pressure to ensure driving safety. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no stamp on top and four small spikes at the bottom, containing an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure.
I've been driving on highways for decades and have encountered high tire pressure situations before. A tire pressure of 2.8 is too high, especially on highways where tires can easily overheat and deform, significantly increasing the risk of a blowout. I've personally experienced the danger of unstable handling. Normal tire pressure should generally be maintained between 2.2 and 2.5. Exceeding this range reduces the tire's contact area and grip, which can be disastrous when encountering sharp turns or slippery roads. I recommend you immediately find a service area to stop and check, using a tire pressure gauge to confirm. If it's indeed that high, release some air to reach the standard value before continuing. Safety first—don't risk it just to save time. The consequences of an accident on the highway are too severe.
