Is a tire pressure of 2.6 normal?
2 Answers
A tire pressure of 2.6 is normal. Tire pressure refers to the air pressure inside the tire. The effects of low tire pressure are: 1. Increased friction coefficient with the road surface; 2. Causes the steering wheel to feel heavy and prone to deviation; 3. Increased movement of various parts of the tire, leading to abnormal heating due to excessive rolling. The effects of high tire pressure are: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear of the tread pattern in the center of the tire, reducing tire lifespan; 4. Increased body vibration, indirectly affecting the lifespan of other components; 5. Excessive stretching deformation of the tire cords, reducing tire elasticity and increasing the load on the car while driving.
I pay close attention to tire pressure when driving normally. 2.6 bar is slightly on the higher side but depends on the specific situation. Generally, passenger cars recommend 2.2 to 2.5 bar. If the label on the door frame indicates a recommended value of 2.5, then 2.6 is still barely acceptable. However, if it's already at this level when the tires are cold, especially in summer when it can easily rise above 2.8, you need to be cautious. Last week, I helped my neighbor release some air—his tire pressure was at 3.0 bar when driving on the highway, resulting in severe wear in the center of the tires. If the tire pressure is too high, the shock absorption worsens, making the ride bumpier, especially in the back seats, and emergency braking grip is also affected. However, if your car is an electric vehicle or SUV, some models recommend around 2.6 bar from the factory. The most reliable approach is to measure it once when the tires are cold. If it exceeds the recommended value by less than 0.3 bar, release some air; if it exceeds by more than 0.5 bar, go directly to a repair shop for adjustment. Don’t forget that tire pressure increases by about 0.1 bar for every 10°C rise in tire temperature.
