Why does a new car experience low tire pressure?

[LaneMarie]

There are several reasons why a new car may experience low tire pressure: 1. The vehicle has been parked for too long, causing tire pressure to decrease: The tire pressure when the car leaves the factory is actually closer to the upper limit of the safe range, but as the car sits for an extended period, the tire pressure will drop. 2. Some manufacturers intentionally lower the tire pressure to prevent excessive speed: Since it's a new car, even experienced drivers need an adaptation period. During this time, to prevent traffic hazards caused by high speeds, the tire pressure may be reduced slightly. 3. Tire damage: Although rare for new cars, this possibility cannot be ruled out. There might be issues with the tires from the factory or punctures during use. When the low tire pressure warning activates in a new car, it's essential to carefully inspect whether the tires are damaged.

I remember when I just bought my new car, the tire pressure warning light came on within the first few days, which was really frustrating. Low tire pressure in new cars is quite common—it might be due to improper adjustment at the factory or gas contraction caused by temperature changes during transport. Especially in autumn and winter, dropping temperatures naturally reduce tire pressure, so don’t worry too much. I suggest you get a tire pressure gauge as soon as possible to check it. The recommended pressure for each tire is usually listed on the driver’s door jamb or in the manual, and filling stations can easily handle this. Regularly checking tire pressure not only saves fuel but also extends tire life and improves driving safety. If it happens frequently, there might be a slow leak or installation issue, so a visit to the shop is needed. For a new car, paying attention to these small details during the break-in period is a good practice.

From my experience, low tire pressure in new cars is mostly caused by temperature changes. In summer, the gas expands when it's hot, and in winter, it contracts when it's cold, which is common for new cars just out of storage. I recommend buying a reliable tire pressure gauge and checking it yourself, preferably every two weeks. The standard tire pressure value is written in the owner's manual, and inflating to the appropriate level will solve the problem. If not corrected, low tire pressure can lead to increased fuel consumption, uneven tire wear, and even affect braking performance. Remember, new cars may have been stored for a long time during transportation, and unadjusted tire pressure is a common issue. Develop good habits, maintain your tires regularly, and drive with peace of mind and safety.

Low tire pressure is no trivial matter. I've seen many new cars experience unstable handling due to this. Common causes include factory settings being too low or pressure dropping with seasonal temperature changes. Quickly check and inflate using a tire pressure gauge, otherwise you risk blowouts or skyrocketing fuel consumption. Safety first - always check your tire pressure gauge before driving, especially with new cars. Proper maintenance can prevent potential hazards.
