What is the general tire pressure for the front and rear wheels of a sedan?

Generally, the normal tire pressure for wheels of household sedans is between 1.8 to 2.4 atmospheres, with the front wheels typically at 2.1 to 2.3 atmospheres and the rear wheels at 2.3 to 2.4 atmospheres. Below is an introduction regarding tire pressure: 1. Locating the standard tire pressure marked for the car: Check the vehicle user manual, the label near the driver's door (B-pillar), the drawer next to the driver's seat, or the small door on the fuel tank cap. For sedans, the tire pressure information is usually found near the door pillar, on the fuel tank cover, or on the side of the front passenger door. 2. Normal tire pressure for different seasons: Winter: Adjust the standard tire pressure of the car tires appropriately, increasing it by about 0.2 bar. Summer: Follow the lower limit of the standard tire pressure for car tires. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures.
Let's talk about tire pressure. For small cars, the front tires generally have a pressure between 30 to 32 psi, while the rear tires range from 32 to 35 psi. Why the difference between front and rear tires? It's mainly because the front tires bear the weight of the engine and require slightly lower pressure to cushion impacts and reduce excessive jolting while driving. If the pressure is too high, the tires become too stiff, leading to reduced road grip and increased risk of skidding during braking. On the other hand, if the pressure is too low, it increases tire deformation, which not only consumes more fuel but also raises the risk of a blowout during long-distance driving. Personally, I make it a habit to check the pressure once a month using an inexpensive pressure gauge—just a few dollars—and the most accurate readings are taken when the car has been parked overnight in a cold state. Modern cars come with a Tire Pressure Monitoring System (TPMS) that alerts you automatically, but older cars require manual checks. Don’t forget to refer to the label on the door frame or the user manual, as the specific values vary for each car model—don’t just inflate based on guesswork.
I've been driving sedans for over a decade and never take tire pressure lightly. Generally, sedan front tires require about 30 psi, while rear tires need around 33 psi. The difference isn't huge because the heavier front end benefits from this balanced distribution for smoother driving. Incorrect pressure directly impacts ride quality: overinflation makes the ride uncomfortably bumpy, while underinflation causes noticeable wobbling at highway speeds and increases fuel consumption. Seasonal temperature changes also affect pressure: cold winters decrease it while hot summers increase it. I check monthly with an affordable pressure gauge – a small investment that saves hassle. Chronic underinflation accelerates tire wear, making premature replacements costly. Get into the habit of topping up for a few minutes during parking stops. Never ignore the TPMS warning light – address it promptly to avoid complications.
