Is the 220 Tire Pressure Too Low for the Mazda3 Axela?
1 Answers
A tire pressure of 220 refers to 2.2 bar, which is considered low for the Mazda3 Axela. According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is between 2.4-2.5 bar. A pressure of 2.2 bar is below the minimum recommended value, indicating it is too low. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel and a tendency to veer off course, compromising driving safety; Increased movement in various parts of the tire, causing excessive rolling and abnormal heat generation; Reduced functionality of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim, and damage to the bead area, resulting in abnormal wear; Exponentially increased friction between the tire and the ground, causing a rapid rise in tire temperature, softening of the tire, and a sharp decline in strength. High-speed driving under these conditions may lead to a blowout; Increased deformation of the tire body, making the tire sidewalls prone to cracking, along with flexing movements that cause excessive heat, accelerating rubber aging, fatigue in the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
