Is it safe to drive on the highway with a tire pressure of 2.2 bar in summer?
2 Answers
A tire pressure of 2.2 bar is too low, and it is not recommended to drive on the highway. If the tire pressure is relatively low, the tire may experience wave-like deformation during high-speed driving. This deformation can accelerate tire aging and increase the risk of a blowout. Hazards of low tire pressure: Increased fuel consumption: Low tire pressure increases the contact area between the tire and the ground, thereby increasing friction and driving resistance, which naturally leads to higher fuel consumption. Reduced tire lifespan: Similarly, due to the larger contact area with the ground, tire wear is exacerbated, shortening the tire's service life. Higher risk of blowouts: Increased friction causes the tire temperature to rise, making the tire softer and reducing its strength. When the tire can no longer support the vehicle's load, especially during high-speed driving, it can easily lead to a blowout.
I believe extra caution is needed when driving on highways with summer tire pressure at 2.2 bar. I often remind my friends that tires bear heavy loads during high-speed driving, and summer heat can cause rapid pressure increase. Starting with 2.2 bar cold pressure may lead to expansion beyond 2.5 bar while driving, increasing risks of tire blowouts or unstable handling. Most vehicles' standard cold pressure ranges between 2.2 to 2.5 bar - check the door pillar label for specifics. If the label recommends 2.4 bar, then 2.2 is somewhat low, affecting braking distance and steering precision. My advice is to visit a professional shop before highway trips to measure and adjust to the recommended value. Safe driving should always be the top priority - a simple check can prevent major accidents. Never underestimate tire conditions on highways as they directly impact overall vehicle safety.
