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.

As a family man with kids, I take tire pressure very seriously because it's a safety issue. For sedan tires, the usual pressure is between 32 to 35 PSI, but it depends on your car model. I check with a tire gauge every two weeks, making sure to do it when the tires are cold to avoid false readings. Low tire pressure is the biggest headache—it can overheat and cause blowouts, especially on highways. High pressure might save some fuel but reduces comfort. I recommend keeping a cheap tire gauge in the car for easy checks. Temperature changes matter a lot—add a bit more air in winter and let some out in summer. Don’t just check the tread; sidewall wear is also a warning sign. Overall, maintaining proper tire pressure can extend tire life by years and save fuel too.

When chatting about cars with friends, someone always asks about the proper tire pressure. For sedans, it's generally around 32 PSI, usually indicated on a label by the door. My new car has a standard of 32 PSI. Overinflating makes the ride harsh and bumpy, while underinflation causes sluggish driving. I prefer using a portable tire pressure gauge for the most accurate reading when the car is stationary and cold. The key is not to exceed 35 PSI, as higher pressure increases tire noise and the risk of skidding.
