Is a tire pressure of 2.7 bar normal for a small car?

A tire pressure of 2.7 bar is not normal for a small car. Generally, small cars use standard tires, and according to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.7 bar exceeds the maximum recommended value, so it is not normal. Hazards of excessive tire pressure: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, and impacts can lead to internal cracks and blowouts, resulting in a tire burst.

I think a tire pressure of 2.7 bar is a bit too high for a small car. Normally, the recommended tire pressure for small cars ranges between 2.2 and 2.5 bar. 2.7 bar is significantly above the standard, and driving with this pressure for a long time can make the tires harder, affecting ride comfort, especially making bumps more noticeable when going over speed bumps. If you're driving long distances in hot summer with such high tire pressure, the tires can easily overheat and even increase the risk of a blowout, which would be dangerous. From my driving experience, it's best to regularly check the tire pressure gauge or go to a repair shop for adjustment. Generally, the recommended tire pressure for your vehicle is indicated on a label attached to the door frame, and referring to that is the safest bet. Additionally, improper tire pressure can accelerate tire wear and increase fuel consumption, ultimately costing more money. If you encounter abnormal tire pressure, don't delay—address it promptly to avoid many potential hazards. After all, safety comes first.
