2. Why should we lower the tire pressure?
According to data from the transportation department, abnormal tire pressure accounts for 12% of traffic accidents. When tire pressure is too high:
| Risk type | Specific performance |
|---|---|
| Risk of tire blowout | Every time the air pressure exceeds the standard by 10%, the probability of a tire blowout increases by 30% |
| braking distance | The braking distance on wet roads is extended by 1.5-2 meters. |
| comfort | Shock absorption effect reduced by more than 40% |
3. 4 ways to safely reduce tire pressure
1.Professional bleed valve operation
Prepare a digital tire pressure gauge → measure when the car is cold → press the valve core to deflate → deflate 0.1 Bar each time → repeat the measurement
2.Seasonal adjustment reference
| season | Adjustment suggestions |
|---|---|
| winter | 0.1-0.2Bar lower than standard value |
| summer | 0.2-0.3Bar lower than standard value |
| Off-road driving | Sand can be reduced to 1.2Bar |
3.Intelligent tire pressure monitoring system assistance
Among the new models in 2023, 78% are equipped with real-time tire pressure display function, and the tire pressure alarm threshold can be set through the vehicle system.
4.emergency treatment plan
If the tire pressure is found to be too high while driving: immediately reduce the speed → find a safe parking spot → wait for the tire to cool down → slowly deflate to a reasonable range
4. Precautions
• Standard tire pressure values vary greatly between different models (refer to the door frame label)
• Modification of tires requires recalculating the appropriate tire pressure
• Check tire pressure at least once a month
• Tire pressure calibration must be done before long-distance travel
Recent popular cases show that correctly adjusting tire pressure can improve fuel economy by 3-5% and significantly extend tire life. It is recommended that car owners scientifically manage tire pressure status based on their car's manual and actual road conditions.
