What is the normal tire pressure for car tires?
2 Answers
Car tire pressure is normally between 2.3bar and 2.5bar. The hazards of low tire pressure: 1. Increased fuel consumption due to higher road friction coefficient; 2. Heavy steering wheel, prone to deviation, which is detrimental to driving safety; 3. Increased movement of various parts of the tire, causing abnormal heat due to excessive rolling; 4. Weakening of cord and rubber functions; 5. Damage to the tire bead area and abnormal wear. The hazards of high tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear of the tread pattern in the center of the tire; 4. Impact on the lifespan of other components; 5. Excessive stretching and deformation of tire cords; 6. Increased risk of tire blowout.
I always consider checking tire pressure before driving as an essential habit. The normal range is typically from 30 to 35 psi, but the exact value should be checked on the label inside the door frame or in the manual. When the pressure is too low, it accelerates tire wear, making it feel like dragging a piece of iron, and fuel consumption also skyrockets; when it's too high, the ride becomes bumpy and uncomfortable, and the tires are prone to slipping when turning. I measure it once a month before driving in the morning when the tires are cold for the most accurate reading, keeping a tire pressure gauge handy to get it done in minutes. In summer, adjust slightly lower due to thermal expansion, and vice versa in winter. Remember, don't wait until a blowout to regret—safe driving relies on these small details.
