Is 3.0 bar tire pressure normal?
2 Answers
Tire pressure of 3.0 bar is not normal. For many vehicles, 3.0 bar is a very high value. According to the provisions and requirements of the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: standard tires should be 2.4-2.5 bar; reinforced tires should be 2.8-2.9 bar; while the maximum pressure should not exceed 3.5 bar. The hazards of excessive tire pressure include: reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive tension on tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreased resistance to punctures.
I've been driving for many years, and a tire pressure of 3.0 bar might be a bit too high. Normal tire pressure usually ranges between 2.0 to 2.5 bar, depending on your vehicle model and tire type. For SUVs or heavy-duty vehicles, it could be slightly higher, but for regular passenger cars, it generally shouldn't exceed 2.4 bar. Excessive tire pressure makes tires more prone to overheating, increases the risk of a blowout, results in a bumpier ride, and extends braking distance. For safety, I recommend checking the label on the door frame or the user manual for the recommended values. Regularly measuring tire pressure with a gauge is crucial, especially during significant weather changes. I once experienced high tire pressure myself, which led to faster wear in the center of the tires, forcing me to replace them after just two years—quite a waste of money. After adjusting to the standard pressure, the ride became smoother and safer. I advise everyone to develop a good habit of checking tire pressure monthly.
