How to deflate tires
Deflating tires is a common operation during daily vehicle use or maintenance. Whether it's to adjust tire pressure, replace tires, or respond to an emergency, it's crucial to know how to deflate your tires correctly. The following is a detailed guide on tire deflation, combining hot topics and hot content in the past 10 days to provide you with structured data and analysis.
1. Steps to deflate tires
1.Preparation tools: Make sure you have a tire pressure gauge and a deflation tool (such as a valve core wrench or fine needle).
2.Check tire pressure: Use a tire pressure gauge to measure the current tire pressure and determine the amount that needs to be deflated.
3.Loosen the valve cap: Rotate the valve cap counterclockwise to expose the valve core.
4.deflation operation: Use a tool to gently press the valve core, or use a fine needle to insert into the valve core to deflate slowly.
5.Retest tire pressure: Measure the tire pressure again after deflating to ensure it reaches the target value.
6.Tighten the valve cap: After the operation is completed, tighten the valve cap clockwise to prevent air leakage.

3. Precautions for tire deflation
1.Safety first: Keep away from fire sources when deflating to avoid tire overheating.
2.Slow operation: Rapid deflation may cause structural damage to the tire.
3.Regular inspection: It is recommended to check tire pressure once a month to ensure driving safety.
4.ambient temperature: Measure tire pressure more accurately when tires are cold.
5.Tool cleaning: Keep the valve core clean to prevent dust from entering.
4. Recommended tire pressure for different models (unit: psi)
| car model | front wheel | rear wheel | Spare tire |
|---|---|---|---|
| small car | 32-35 | 30-33 | 60 |
| SUV | 35-38 | 33-36 | 60 |
| MPV | 36-40 | 38-42 | 60 |
| pickup truck | 45-50 | 45-50 | 60 |
5. Frequently Asked Questions about Tire Deflation
1.Q: Do you need to perform dynamic balancing after deflating the tire?
A: Simply deflating is not necessary, but if the tire has been disassembled, dynamic balancing is recommended.
2.Q: How to tell if a tire is over-deflated?
A: Tire pressure 25% lower than the manufacturer's recommended value is considered excessive and will cause the tire sidewall to bend excessively.
3.Q: How to deflate the air in an emergency without tools?
A: You can use small objects such as keys to lightly press the valve core, but be extra careful.
4.Q: How long does it take for a tire to be completely deflated?
A: Depending on the degree of damage to the valve core, light leakage may occur within a few hours if it is completely damaged.
5.Q: Why do cars need to be specifically deflated?
A: By reducing tire pressure, the ground contact area is increased and cornering grip is improved.
6. Tire maintenance tips
1. Check tire pressure before every long trip.
2. It is recommended to drive no more than 80km/h after the tire is deflated.
3. The spare tire should maintain a high tire pressure to ensure emergency use.
4. Use tire pressure monitoring system (TPMS) to monitor in real time.
5. It is recommended to readjust the tire pressure when rotating tires.
Through the above content, I believe you have mastered the correct method and related knowledge of tire deflation. Proper maintenance of tires can not only extend their service life, but also ensure driving safety. Remember to check the condition of your car's tires regularly. Safe travel starts with tires!
