How much air pressure should be added to car tires?
2 Answers
The recommended air pressure for car tires is between 2.3 and 2.5 bar. The method to check car tire pressure is as follows: 1. Unscrew the tire valve cap; 2. Insert the measuring head of the tire pressure gauge into the valve stem; 3. Read the measured data on the tire pressure gauge. The impacts of abnormal tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causing steering wheel vibration and deviation, reducing driving comfort; 3. Accelerating wear on the central part of the tire tread, shortening tire lifespan; 4. Weakening the function of the cords and rubber, leading to delamination or cord breakage, and causing excessive friction with the rim, resulting in damage and abnormal wear to the tire bead area.
I think the tire pressure for sedans depends on the specific vehicle, usually between 30 to 35 PSI. For example, my daily commuter car is set at 32 PSI. I remember once before a long trip, I didn't check the tire pressure, and it was only at 28 PSI. The fuel consumption shot up, and I almost had a blowout. Since then, I've made it a habit to check once a month, using an inexpensive tire pressure gauge in the morning after the car has been parked for a few hours, as this gives the most accurate reading. By the way, tire pressure tends to increase in the hot summer months and decrease in the cold winter, so adjustments are necessary. Different car models have different requirements, so I recommend checking the vehicle manual or the small label on the driver's side door—it's usually very clear. Low tire pressure not only wastes fuel but is also dangerous, while high tire pressure can cause uneven tire wear. Balance is key. Regular maintenance can save a lot of money and extend the tire replacement cycle.
