Punch in the magic capital to shoot the holy land and make up a commemorative photo for the pioneers! Including tire maintenance skills.

This summer, although Shanghai has never experienced a severe typhoon, the sky has been surprisingly blue recently. How can this photo opportunity of waiting for another year be wasted?

Think about it. I have been very busy since I brought the pioneer back, and I haven't officially taken a group of commemorative photos of it. It's better to hit the sun when choosing a day. On a good day, please invite the royal photographer An An, and the Wisdom Bay Creative Park will be launched soon!

Speaking of Magic Capital Wisdom Bay, it has been very popular in Little Red Book recently. There are a lot of buildings with overlapping containers in the park, which are more colorful than the blue containers in Seoul, including blue, orange, yellow and green. At the same time, there are many small terraces and stairs, which are very suitable for taking pictures, so there are many little sisters and brothers who come here.

Wash one carefully before taking pictures! Friends who often read my posts may ask, why did you go to intensive washing again? I'm really not being melodramatic. Units and communities only have ground parking spaces, which I naturally understand! Even though Pioneer's silver car paint is resistant to dirt, it can't escape the life of washing once a week.

After carefully washing the car and driving past, the whole person felt refreshed. Please raise your hand if you feel the same way. After driving more than 3,000 kilometers, I like the four-spoke steering wheel on Pioneer more and more. I have a good grip and I can use all kinds of buttons very easily. Sensually speaking, the four-spoke steering wheel is more American, more powerful and more suitable for a 5-meter-long body. what do you think?

Go north along the north-south elevated road, and you can reach Wisdom Bay in 20 minutes by car. It is also very convenient if you come by subway. Take Exit 4 of Hulan Road Station and cross the overpass. We entered the park at about 4 o'clock 15, when the light was just right. After a little preparation, Nankai began his creation.

I have to say that the photos taken by professional cameraman An An are just different, just like the official photos. You can ask me for the original picture in private if you like. Do computer desktop background, mobile phone wallpaper are good.

In order to reward the photographer, I specially invited Ann to go fishing in Haidilao after the photo shoot. I have to say, I'm really tired when I wait in line. I went after eating 1 1. On the one hand, I was in a hurry to go home, on the other hand, I found that the left rear tire pressure was obviously abnormal. Specifically, tire pressure fluctuates with temperature. Generally, it is recommended to keep the tire pressure of cold tires at 230-240kPa and that of hot tires at 250-260? Kpa. If you only look at the 236 of the left rear tire? KPa, it seems that there is nothing wrong, but compared with the tire pressure of the other three tires, there is a problem, which is the main reason why I have always suggested displaying an information screen on the tire pressure. However, from experience, the left rear tire should have just been punctured with a small incision.

Because there are still 236? KPa tire pressure, so it is impossible to detect the abnormality of the tire from the appearance alone, even if you are a decades-old driver. However, tires can't fool the tire pressure monitoring system on the car. Here, I want to give Chevrolet a manual compliment. It is understood that most Chevrolet models come standard with this system, which is really intimate!

Although the puncture is not big, in order to reduce unnecessary secondary injuries, I decided to change the spare tire. You can also take this opportunity to show you the key steps of tire change. First of all, of course, it is necessary to pull over and change the tires in a place that does not affect the passage of other vehicles and can ensure your own safety. According to the regulations, warning signs should be set 50 meters behind the car in general urban ring roads during the day. If it is an expressway (about 200 steps for adults), it should be at the back of the car 150 meters; If it is in the dark and the city ring road encounters a vehicle failure, it is necessary to set a warning sign at the back of the vehicle 100 meters, while on the expressway, it should be set at a position of 250 meters (about 300 steps for adults).

Pioneer's spare tire is not under the car, but under the storage compartment in the trunk. There are fixed knobs on both sides, and you can see the spare tire and jack when you remove it.

This is the fulcrum position of the left rear car body. Only when the jack is supported here can it be more stable and will not cause harm to the car body.

Regardless of the disassembly and assembly of nuts, we should follow the diagonal principle to make the force more uniform. In addition, when reassembling, do not screw it too tightly to avoid damaging the thread.

Although the spare tire can run 80 yards per hour, I still put the tire repair on the first thing to do the next day. Now I go to Michelin for tire repair, and the master usually recommends mushroom nails, and the effect is naturally the best, but if the incision is small, I can also consider traditional patch tire repair, and the effect should be no different. The most important thing is to do dynamic balance after tire repair, otherwise there will be jitter when driving at high speed. Informal stores either skip this step directly or charge extra fees, so everyone must pay attention.

In addition, the original car tires are 20 inches, which requires a large tire scraper. Be sure to ask before disassembly, so as not to hurt the tires and wheels. I asked the price casually when repairing the tire, and the reply was that the original factory was equipped with 235/55? R20 Michelin PRIMACY? SUV, a tire is about 2000 yuan, Chevrolet is really a waste! Ultrafine products also added that BMW X 1 and Acura CDX were originally equipped with this kind of tire, which has very balanced performance and good reputation. It's expensive for a reason. From my experience, first of all, it's really quiet. Even up to 120 yards, the tire noise introduced into the car is very limited. Secondly, the grip is really good. Similarly, on the ramp in Puxi, nanpu bridge, it is obviously possible to pass at a faster speed. Even if it rains, the grip is still sufficient, full marks!

By the way, I took this opportunity to mend the tire and fill it with nitrogen that I have long wanted to try. Because nitrogen is an inert gas, it is least affected by temperature changes. Generally speaking, as long as there is no air leakage, the tire pressure can be maintained at a fixed value in winter and summer. Before filling with nitrogen, the original air in the tire must be emptied as much as possible. The scene looks a bit miserable, but the master in the shop said that as long as you don't roll, you won't hurt the tire in such a short time.

Through the observation of these two days, even if the temperature difference in Shanghai can reach nearly 10 degrees a day, the change of tire pressure is only 4kPa, so it can be said that changing nitrogen is very successful. It does not hurt the tires, but also ensures the driving safety. I strongly suggest you give it a try!

At present, it is 4 thousand kilometers, which is the first insurance at first sight. I will also record it in detail and post it to share with you. Finally, thank you for your support and welcome your comments. See you in the comments section!
