What is the standard tire pressure for car tires?
2 Answers
The standard tire pressure for car tires is between 2.2 and 2.5 bar. Tire pressure refers to the air pressure inside the tire. The impacts of abnormal tire pressure include: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Causing steering wheel vibration and deviation, reducing driving comfort; 3. Accelerating uneven wear of the central tread pattern, shortening tire lifespan; 4. Overstretching and deforming the tire cords, reducing tire elasticity and increasing the load on the car during driving; 5. Increasing the movement of various parts of the tire, leading to abnormal overheating due to excessive rolling.
When I first started driving, tire pressure was also a problem that troubled me. The standard value is usually between 30 and 35 pounds per square inch, depending on your car and tire type. The manual or the label on the door frame will have clear recommendations. I got into the habit of checking it once a month because if the pressure is too high, the ride feels too bumpy and hard, affecting comfort; if it's too low, it increases the risk of a blowout and makes the car handle poorly, especially during high-speed turns. Especially on rainy days when the road is slippery, incorrect pressure can easily cause skidding. Usually, after parking, the tire temperature rises, so it's best to check it early when the tires are cold, using an accurate pressure gauge. After developing this habit, my tires lasted over five years without needing replacement—safe and worry-free.
