What is the normal range for tire pressure difference?
1 Answers
A difference of 0.1-0.2 bar in tire pressure is within the normal range. Generally, vehicle tire pressure should be maintained around 2.3-2.5 bar. However, due to thermal expansion and contraction effects, it's normal for summer tire pressure to be 0.1-0.2 bar lower than the standard range. Conversely, in winter, it's normal for tire pressure to be 0.1-0.2 bar higher than the standard range. In reality, it's quite difficult to achieve identical pressure in all four tires unless you're obsessive about it. However, it's important to note that uneven tire pressure between left and right tires can lead to braking time differences, operational instability, steering difficulties or heaviness, while also reducing tire lifespan, increasing puncture risks, and raising fuel consumption. These issues become more pronounced when the vehicle is heavily loaded. How dangerous is the pressure difference between left and right tires? There's no precise numerical threshold, but generally it's best not to exceed 0.2 bar difference. The normal tire pressure range is typically between 2.3-2.5 bar. When carrying a full load (5 passengers), adjusting tire pressure to around 2.5 bar is more appropriate; for two passengers, 2.3 bar is normal. However, different vehicle types including domestic cars, private vehicles, and vans have varying factors like body weight and chassis height. Manufacturers' standard tire pressures differ. Therefore, the recommended tire pressure should follow your vehicle manufacturer's specifications, as tire pressure settings primarily consider vehicle-specific factors like body weight and chassis height. It's not necessarily related to tire brands. Unless the manufacturer specifies otherwise, no special seasonal adjustments are required for winter or summer. Of course, it's recommended to measure tire pressure at normal temperature conditions.
