Where to Inflate Tires with Insufficient Pressure?
2 Answers
Tires with insufficient pressure can be inflated at auto repair shops or 4S stores. Alternatively, a bicycle pump can also be used for inflation. It is recommended to purchase a portable electric car air pump (ensure it comes with a tire pressure monitoring device) and keep it in the car for convenient tire inflation anytime. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to tire leaks or low pressure to ensure driving safety. The working principle of tire pressure monitoring is that an internal sensor is installed on the tire hub. This sensor includes a bridge-type electronic pressure sensing device that detects air pressure, converts the pressure signal into an electrical signal, and transmits the signal via a wireless transmitter.
The other day I noticed my tire was a bit flat, so I drove to a nearby repair shop in my neighborhood. The owner used an air gun with a pressure gauge to refill it and reminded me to check the tire pressure label on the door frame when the car is cold. Nowadays, many gas stations also offer free air pumps—just insert a coin to use them, and the operation is super simple. Later, I bought a portable air pump to keep in the trunk, so in emergencies, I can just plug it into the cigarette lighter for self-service inflation, which gives me peace of mind on business trips or long drives. Remember to unscrew the valve cap before inflating, and after filling, give the tire a squeeze to check its firmness—don’t overinflate or underinflate.
