Household car tire pressure varies depending on the type of tire: 1. Standard tires require 2.4 to 2.5 bar; 2. Reinforced tires require 2.8 to 2.9 bar. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support vehicle load; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging car components. The hazards of low tire pressure are: 1. Reduced tire lifespan; 2. Increased tire wear; 3. Elevated tire temperature after driving due to low pressure may cause blowouts, and the tire sidewalls are prone to deformation during driving; 4. Decreased tire adhesion while driving, leading to abnormal bumpiness.

As an ordinary car owner with over 20 years of driving experience, I firmly believe that maintaining proper tire pressure at the recommended value is crucial for family vehicles. Specifically, most car models have stickers on the door frame or fuel cap indicating the ideal range, typically between 32 to 35 PSI. Excessive pressure causes uneven tire wear and unstable handling, while insufficient pressure increases the risk of blowouts, especially on hot summer roads. I always carry a portable tire pressure gauge and check after refueling to ensure consistent pressure across all tires. Remember to adjust for load variations – when carrying a full family, slightly increase the pressure to around 38 PSI. Developing a regular inspection habit is vital, as neglecting this can waste fuel and damage the vehicle. This simple procedure takes just minutes but significantly enhances driving safety.

When I was young and driving a family car, I learned the hard way about improper tire pressure during a long trip when I noticed abnormal tire wear. Since then, I've made it a habit to check the pressure monthly. The standard pressure ranges from 30 to 35 PSI depending on the vehicle model—mine is marked at 34 PSI. A cheap tire pressure gauge and a flat surface are all you need. Overinflation makes tires stiff and hard to control over bumps, while underinflation increases fuel consumption—losing 5 PSI can burn 1% more fuel. Seasonal changes matter too; cold winter air can reduce pressure, while summer requires caution against overheating. I often remind friends to check the manual instead of guessing—safety first saves money and time.

The recommended tire pressure range for family cars is 30-35 PSI, but always refer to your vehicle's manual. The minimum pressure is printed on the tire sidewall, but don't use that as your standard - the normal unloaded pressure is around 33 PSI. Overinflation reduces traction and increases hydroplaning risk in rain; underinflation accelerates wear and shortens tire life. Use a simple tire gauge to check monthly, ensuring even pressure. Measure when tires are cold, and don't forget the spare tire - it needs equal attention to stay ready. This simple routine ensures safety and saves money.
