What is the minimum tire pressure that should not be lower than?
1 Answers
Tire pressure below 1.7bar is not safe for driving. Tire pressure refers to the air pressure inside the tire. The level of tire pressure plays a crucial role in the performance and power of the vehicle. There is no exact numerical regulation specifying how low the tire pressure can go before it becomes unsafe, but it is best not to go below the manufacturer's recommended value, which is generally 2.2-2.5bar. Additional Information: Note 1: The manufacturer's recommended tire pressure can usually be found in the vehicle's user manual or near the door (B-pillar or C-pillar). Low tire pressure can cause significant damage. Firstly, the tire's own motion friction coefficient increases, the contact patch becomes flatter, and there is a movement process between the normal condition of the non-contact patch, causing the tire to not run in a perfect circle, leading to an increase in tire temperature. Secondly, low tire pressure increases the deformation of the tire body, making the tire sidewalls prone to cracking and causing flexing motion, which leads to excessive heat generation, rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area, accelerating wear on the tire shoulders, which can result in a blowout. Note 2: Tire pressure is an important factor affecting tire lifespan and fuel economy. Choosing an unreasonable tire pressure can cause power cycling, increasing tire wear and reducing lifespan. Considering the impact on vehicle performance, it is essential to select the appropriate tire pressure to extend tire life and improve fuel economy.
