How to Check 2.5 on a Car Air Pump?
2 Answers
You can check the red numbers on the inner ring of the car air pump's pressure gauge. Generally, it ranges from 2.2 to 2.4, and in winter, the front tires should be at 2.5 kg. Not only can it be used to inflate car tires, but it can also be used at home for inflating bicycle tires, making it quite convenient. It can not only be used for inflation but also for tire inspection, reducing tire wear and providing an extra layer of safety for driving.
When using the car air pump set to 2.5 bar, first check the pressure gauge on the pump to ensure it has a digital display for better visibility. After starting the pump, connect it to the tire valve and turn on the switch—it will inflate automatically. Watch the display as the value gradually increases; I start paying attention when it reaches 2.0 and quickly press the stop button once it hits 2.5 to avoid overinflation, which could deform the tire. My SUV’s manual recommends a range of 2.3-2.8 bar, and 2.5 is ideal for daily city driving. I suggest checking tire pressure monthly and ensuring the tires are cool before using the pump, as hot tires can lead to inaccurate readings and compromise driving safety.
