What to Do When Car Tire Pressure is Too Low?

Tire pressure too low: If you have an onboard air pump, you can first inflate the tire a little and then slowly drive to the nearest repair shop for further handling, or replace it with a spare tire before going for repairs. Below are relevant explanations about low tire pressure: 1. When a car's tire pressure is too low, the most obvious phenomenon is an increase in the vehicle's fuel consumption. 2. Because low tire pressure increases the friction between the car's tires and the ground, the running resistance increases, leading to higher fuel consumption. At the same time, the tire's movement will also increase, as the increased friction will raise the tire's temperature, causing it to soften and thus reducing its usage strength. 3. If driving at high speeds for a long time, it may even lead to a tire blowout, threatening driving safety. 4. The reasons for low tire pressure can generally be divided into three categories: first, thermal expansion and contraction due to low temperatures; second, air leakage from the tire; and third, the tire may be improperly installed or the tire edge may not be properly fitted with the rim, resulting in poor tire sealing.
When the car tire pressure is too low, I prioritize safety concerns. Because insufficient pressure can easily cause tire deformation and increase the risk of a blowout, especially on highways. If I notice the tire pressure warning light on the dashboard or the vehicle swaying unsteadily while driving, I immediately slow down and pull over to a safe spot, turning on the hazard lights to avoid being rear-ended. Then, I check the tires for obvious nails or punctures. If I have a portable air pump, I connect it to the cigarette lighter to inflate the tire to the standard pressure, usually indicated on the label by the door (e.g., 2.3-2.5 bar). If the tire quickly deflates again after inflation, it indicates a slow leak, and I must not force driving—instead, I should call for roadside assistance. Normally, I use a tire pressure gauge monthly to check the pressure and avoid underinflation, which reduces fuel efficiency and tire wear. Remember: safety comes first—don’t risk driving to save time. Low tire pressure worsens handling and increases skidding risks, especially in changing weather conditions, so prevention is key.
