What is the normal range for car tire pressure?
2 Answers
Car tire pressure is considered normal between 2.3 to 2.8 bar. In summer when temperatures are high, the gas inside the tires expands, so the tire pressure should generally refer to the minimum pressure value indicated on the tire. In winter, it can fluctuate within the above range. For old tires, it is recommended to use the lower limit as the standard. If the wear is severe, please replace them promptly to prevent blowouts during driving. Both overinflated and underinflated tires will affect tire performance and driving safety. When tire pressure is too high, it reduces tire adhesion and affects braking performance. Drivers may feel vibration in the steering wheel, and in severe cases, it may even cause the car to pull to one side. When tire pressure is too low, it increases the contact area between the tire and the ground, raising the friction coefficient, accelerating tire wear, and reducing tire lifespan. Additionally, low tire pressure increases movement in various parts of the tire, causing excessive rolling, abnormal heat buildup, weakening of the cord and rubber functions, leading to delamination or cord breakage, and resulting in abnormal wear.
I think tire pressure is really important as it relates to driving safety. Generally, the normal tire pressure range is between 32 to 35 PSI, depending on your car model - the label on the inside of the door has specific recommendations. Too low tire pressure increases the risk of blowouts and fuel consumption; I once neglected it and ended up with uneven tire wear. Too high pressure makes the ride feel bumpy and uncomfortable. I make it a habit to check with a tire gauge monthly, especially when temperatures drop as pressure decreases faster then - extra attention is needed. Don't forget the spare tire either, as its pressure drops over time. Maintaining proper tire pressure not only extends tire lifespan but also improves handling, giving me more peace of mind while driving.
