Bella was stunned for a moment and stopped the car. She looked at the screen and said, "Oh no."
"What's wrong?" Su Yang asked with his head tilted.
"The tire pressure is too low, only 130."
"Why does it suddenly say that the tire pressure is too low? Could it be that there is a nail stuck in it?" Su Yang said after looking at the central control screen.
"I don't know. I've never encountered such a situation before." Bella looked a little anxious.
Su Yang comforted him, "It's okay, I'll get off the car and take a look."
As he spoke, he opened the car door, got out, walked around to the left rear wheel, squatted down, took out his cell phone, turned on the lights to check.
This tire is obviously flatter than the front wheel at this time.
Su Yang shone the light around and reached out to touch the inside of the tire where the naked eye couldn't see.
After inspection, no traces of nails were found.
Su Yang tilted his head and shouted towards the driver's seat: "Bella, drive the car forward a little."
"Okay." Bella agreed and moved the car forward.
Su Yang stared at the tire and shouted again: "OK, stop!"
The car stopped and Su Yang continued to squat and check the part of the tire that had just been pressed to the ground.
"How is it?" Bella also got out of the car and squatted beside Su Yang to help turn on the lights.
Su Yang shook his head: "I checked it all, and I also touched the places that can't be seen inside. I am very sure that there are no nails."
"What should we do now?" Bella asked in surprise.
"There are only a few reasons why a tire might leak. Besides being punctured by a nail, tire aging, wheel hub deformation, or valve stem aging can all cause leaks. But I've checked all of these and they're all fine."
"Ah! What's that?"
Su Yang thought: "Shouldn't I ask you this?"
"It's okay, it's not a big deal. Is there a portable air pump in this car?"
"Air pump?" Bella scratched her cheek and deliberately leaned closer to Su Yang and said, "This is my mother's car. I'm not sure where it is. Let me look for it."
"Okay." Su Yang helped Bella stand up.
Bella stared at Su Yang and bit her lower lip naturally and said, "Thank you, Mr. Su."
"You're welcome. Open the trunk and let me see."
"good."
Bella quickly opened the trunk. Su Yang bent down to look. There wasn't much inside, but there was indeed a portable air pump.
'Hey, I knew there was one.'
"Found it." Su Yang took out the thing and said with a smile.
"Really?" Bella said pretending not to know.
"Yes, people who drive frequently usually keep one of these in the trunk for emergencies. We just need to fill up the gas."
"Okay." Bella stood behind Su Yang with a lamp on to help illuminate the area.
Su Yang connected the interface and pressed the switch.
Buzz buzz buzz——
In the quiet night, the noise of the air pump was extremely harsh.
"It's such a loud noise." Bella said behind Su Yang.
"There's nothing I can do. Your mother's air pump is quite old, so it's going to be quite noisy. Just bear with it and it will heal quickly."
"good."
A few minutes later, the tire pressure display had reached 240. Su Yang unscrewed the interface and quickly installed the air valve.
After finishing, he stood up with his things and was about to put them back in the trunk.
But at this moment, Bella suddenly stepped forward and stretched out her right hand to block Su Yang.
Then she opened the back door with her left hand and used her body to push Su Yang onto the seat.
