How much air should be put in tires?

Tire pressure should be maintained between 2.4 to 2.5 bar. The hazards of overinflating tires include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Increased steering wheel vibration and deviation, lowering driving comfort; 3. Accelerated wear on the central tread pattern, shortening tire lifespan; 4. Increased vehicle vibration, indirectly affecting the lifespan of other components. Tire maintenance methods include: 1. Regularly removing stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Adopting careful driving habits by choosing smooth road surfaces and avoiding objects that could puncture or scratch tires, as well as chemical spills that may corrode tires.
I've been driving for over a decade, and tire inflation depends on the vehicle type. Sedans generally recommend 32 to 35 psi, while SUVs might require slightly higher at 35 to 38 psi. The standard pressure for each vehicle is indicated on the small label on the door frame or can be found in the user manual. Never overinflate—I once experienced a near-accident on the highway when high pressure caused a tire bulge in summer heat. Underinflation increases fuel consumption, accelerates wear, and lengthens braking distance. Seasonal changes matter too: add a bit more in winter to compensate for cold contraction, and reduce slightly in summer to prevent expansion. Make it a habit to check monthly with an inexpensive pressure gauge or use the self-service air pump at gas stations. Safety first—maintaining proper pressure ensures smoother driving, better fuel efficiency, and extends tire life.
As a parent with children at home, I pay special attention to tire safety. Generally, the tire pressure should be within the recommended range. For example, the label on my family car indicates 34 psi for the front tires and 36 psi for the rear tires. Overinflating makes the tires hard and bumpy, making children uncomfortable, while underinflating increases the risk of rollover, especially in rainy conditions with poor control. I regularly check the tires with my child and keep a note in the car to record the values for reference during inflation. When carrying heavy loads, I increase the rear tire pressure to, say, 35 psi, while keeping it lower for city driving with no load. Temperature fluctuations also affect tire pressure—reduce it slightly in hot summers to prevent blowouts and increase it slightly in cold winters. Remember, balance is key; otherwise, uneven wear can affect tire balance. Daily maintenance is simple—just buy a digital tire pressure gauge and check it monthly.
