Is a Tire Pressure of 2.2 Normal?
2 Answers
A tire pressure of 2.2 is not normal and is slightly low. According to international standards and requirements: standard tires should be between 2.4 and 2.5 bar, reinforced tires between 2.8 and 2.9 bar, and the maximum tire pressure should not exceed 3.5 bar. In winter, it is advisable to increase the tire pressure by about 0.2 bar based on the standard tire pressure, while in summer, the lower limit of the standard tire pressure should be followed. The dangers of low tire pressure include: 1. Increased friction with the road surface, leading to higher fuel consumption; 2. Making the steering wheel heavy and prone to deviation, which can compromise driving safety; 3. Increasing the movement of various parts of the tire, causing excessive rolling and abnormal heating of the tire.
I've been driving for twenty years, and a tire pressure of 2.2 bar sounds within the normal range. For example, most small cars recommend 2.2 to 2.5 bar, and I often see this standard value on the door frame. If it's a bit low, it may increase tire wear, lead to higher fuel consumption, and pose a safety risk of tire blowouts. I make it a habit to check the tire pressure with a gauge every month, especially during seasonal changes when tire pressure can fluctuate. It's better to add 0.2 bar in winter. Don't overlook this—I once neglected it and ended up with a cracked tire sidewall, costing me a lot to replace. Remember, for older cars or when carrying heavy loads, you should adjust the pressure higher. Safety first is what truly matters.
