On the western Sichuan Plateau, the road conditions and weather are complex and changeable, and accidents occur frequently along the way!
At high altitudes, there are tests for both people and vehicles.
Entering the plateau area, there are many details to pay attention to.
For example, some people say that on the plateau, the vehicle tires need to be deflated?
But in fact, this trip to western Sichuan went to the plateau area, and I was replenishing the air pressure~
The original model Y is equipped with Goodyear e Ruicheng tires, from Kangding to Tagong Town, it is a serpentine mountain + sharp bend road conditions, Modely does not have a spare tire, I am more worried about tire problems.
However, in fact, Goodyear E Ruicheng is very stable in dealing with such road conditions, and it is also very sensitive to complex weather changes: hail, sleet and low temperature weather.
In order to ensure the balanced performance of the tires, after entering the west of Sichuan, the tire pressure has been supplemented to 2.9 Bar when starting from Chengdu, and only 2.65 Bar after entering the plateau, at this time, the tire pressure is supplemented to the official recommendation of 2.9 Bar. (The tire pressure increases after going from the plateau to the plain, so it is necessary to deflate at this time.)
All the sealed packaged food carried in the car is flatulent, and it stands to reason that the tire pressure will also increase?
But in reality, I'm replenishing my qi?
Sleet weather, slippery road surface~
The weather is changeable, and the fog suddenly drops~
Plateau supplemental tire pressure, this is inconsistent with the principle of atmospheric pressure in middle school physics textbooks?
In fact, tire pressure is affected by the air pressure on the one hand, and the temperature on the other. The temperature on the mountain shows 8 °C, and the temperature at the top of the mountain pass is only 2 °C, on the other hand, there is also the driving situation, because there are too many factors affecting the tire pressure, so the answer about deflation/refueling/holding is not fixed. Therefore, some of the riders who travel to the west of Sichuan by car say that the tire pressure has become higher on the plateau, some say that the tire pressure has become lower, some say that they need to be deflated at an altitude of more than 4,500 meters, and some say that they have come back without deflating......
The most important thing: maintain a proper tire pressure value.
Driving safety.
Remember, don't overtake in corners! Some sections of the plateau highway have complex terrain and often encounter narrow detours. The road in the grassland is generally straight, the road condition is better, and the speed of the car is up to 100 unconsciously in the process of driving, and it is easy to rush out of control when encountering a sharp bend. There is a certain drop between the road surface and the grass, which can easily cause rollover accidents.
Pay attention to the driver's high reverse.
Driving at altitude should also pay attention to whether the driver will have altitude sickness, and it is quite dangerous for the driver to drive with high reaction symptoms. It is best to have some oxygen cylinders on hand for the first time entering the plateau, just in case.
When entering the plateau area, safety cannot be ignored, and the journey can only be called perfect when safety is accompanied by beautiful scenery. Entering the west of Sichuan (Line 318) encountered many vehicle failures along the way (mainly the high temperature problem of the gearbox of a certain automobile brand on the uphill section of Zheduo Mountain), in addition to slippery runaway, corner overtaking, rear-end collision and other traffic accidents, the most remaining problem is the tire problem. I took photos of some vehicle breakdowns/accidents, and I hope that all riders will pay attention to the details of the trip and safety issues.
Out-of-control rear-end collision on the way down~
Lost control and rear-ended, and another BYD rushed to the hillside 50 meters ahead.
Rear-end collision~
This little brother's tire burst when it was hit by a stone [plateau tires are easy to get injured], and he wouldn't change the spare tire for a long time, and finally helped him.
Xindu Bridge - Kangding, Zheduo Yamaguchi, two tires of a car are hung up, this is definitely not pricked, the front and rear of the driver's seat are out of gas, even if there is a spare tire, it is not enough, this should not be the reason for too bad luck~
That's all for sharing, thanks for appreciating~
There are thousands of roads, safety first, only safety and beautiful scenery go together, the journey is perfect.
END.
