What is the tire pressure for a sedan?
2 Answers
According to the international GBT2978-2008 standard, the requirements are divided into the following five points: 1. Standard tires: 2.4-2.5 bar. 2. Reinforced tires: 2.8-2.9 bar. 3. Maximum pressure: Should not exceed 3.5 bar. 4. Driving on rough roads: Appropriately reduce the tire pressure by 0.1-0.2 bar based on the standard tire pressure. 5. It is also related to factors such as season, road conditions, and tire wear: In summer, try to maintain the lower limit of the standard tire pressure, while in winter, it is advisable to slightly increase the standard tire pressure by 0.2 bar.
I've driven sedans for many years and found that tire pressure is usually between 2.3 to 2.5 bar, or 32 to 35 psi. But don't guess randomly—each car is different, so it's best to check the label on the driver's side door or the sticker inside the fuel cap. If the pressure is too low, the tire edges wear out quickly, cutting the tire's lifespan in half. If it's too high, the center wears out faster, and the car is more prone to skidding, especially in rainy conditions, which is dangerous. I make it a habit to check once a month—a cheap tire pressure gauge will do, costing just ten bucks. Weather changes have a big impact: in summer, heat causes pressure to rise quickly, while in winter, cold temperatures may lower it, requiring a top-up. Neglecting it long-term can lead to blowouts, so forming this habit is crucial. A quick glance at the tires before driving regularly also helps.
