What is the general tire pressure for car tires?
2 Answers
The tire pressure of a car should generally be maintained around 2.2-2.5 bar. What is the standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Other related questions: Is a tire pressure of 2.0 bar normal? No. According to the international GBT2978-2008 standard, the standard tire pressure for standard tires is 2.4-2.5 bar. A pressure of 2.0 bar is below the minimum recommended value, so it is not normal. What is the normal tire pressure in winter? — In winter, the tire pressure should be based on the standard tire pressure of the car, with a slight increase of about 0.2 bar. What is the normal tire pressure in summer? Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be slightly lower than the standard by about 0.1 bar to prevent tire blowouts due to high temperatures.
Having driven for over a decade, I fully understand the importance of tire pressure. The standard tire pressure typically ranges between 30 to 35 PSI, depending on your vehicle model and tire type. For instance, my Honda Civic manual specifies 32 PSI. Tire pressure below 30 increases fuel consumption and tire wear, and raises the risk of blowouts on highways; while above 35 may save some fuel, it reduces traction and dangerously extends braking distance in rain or snow. Make it a habit to check with a tire gauge monthly when the car is cold in the morning, and always recheck before long trips or highway drives. Seasons greatly impact it: in summer when temperatures rise, pressure can exceed 35 PSI—I slightly deflate to around 32 PSI; in winter if it drops below 30, add some air. Prioritizing tire pressure prevents accidents, extends tire lifespan, and ensures driving safety.
