First, the reason for changing the tire
The sound insulation level of this generation of 5 series is OK, and the main noise comes from tires.
Recently, there have been more high-speed runs, and the tire noise of the original Pirelli P7 explosion-proof tire is unbearable.
I have always planned to change an ordinary tire, and it just so happens that my other car is using the Goodyear I car. Over the past three years, Goodyear has performed well in silence, grip, wetlands, and durability. I feel that all aspects are quite balanced. I remember that after changing into Goodyear, I never encountered the slipping phenomenon of the original rice fat man’s underground garage, and the mute performance of the comprehensive road conditions also left a good impression on me. There seems to be no problem except for a few nails. In addition, there is a design of this generation that I think is quite good, that is, the protection of the circle higher than the hub can protect the hub very well. I don’t know why this design was cancelled in the next two generations. Based on the above experience, this time to change the ordinary tire for the 5 series, I simply set the goal of changing the tire on the Goodyear imperial ride III.
After three years of birth, the tire pattern is still beautiful, and I feel that it will not be a problem to fight for a few more years.
Here are some beautiful pictures of your car in autumn.
Second, prepare for tire change
The picture comes from a screenshot of an e-commerce platform.
Do not fight an unprepared battle, although I know a little bit about some basic parameters of tires and some practical experience of Goodyear brand, I still do a little homework before changing tires. The main thing is to go online to find out the conditions of changing the tire, the type of the tire, the basic parameters and so on, and then judge whether it is in line with my vehicle. There is to compare the prices of various platforms, preferential activities and so on, this will not be said.

What I mainly know is the specifications of the tire and the date of production. For example, my car tire size is 245 / 45 R18. Compared with the picture above, we know that the tread width is 245 mm and the flattening ratio is 45, which is much better than the 19-inch tire on the 530 model. Therefore, it is said that the phenomenon of 18-inch tire drum on the 5-series is much less than the 19-inch tire. R means radial tires (the tires on most models are), and 18 indicates that the hub is 18 inches in diameter. As for the speed level, load index and so on, the design of civil tires is far from enough to meet the conditions of our daily car use.
Combined with this change of the Goodspecial imperial ride III generation to learn more about it. The first thing to see is the Goodyear brand on the side of the tire.
There is also the famous Flying foot logo, which can be learned by interested cyclists.
Then there is the production date that I am more concerned about. What I got is the 35th week of 2022, Gagaxin, which should be produced in the third week of September this year.
Of course, the tire specifications must be checked and must match your own car. 245 / 45 R18 100W, all OK against the tire specifications above.
The inner wall of the tire used to be like this. Is the pattern very beautiful?
Replace it with Goodyear
I learned last Wednesday that the tires had been delivered to the store, so on Saturday afternoon, after checking the local epidemic and epidemic prevention, I drove to the Goodyear tire store.
Four Gaga new Goodrich III are lined up in front of the car.
After a brief understanding of the label on the tire, Goodyear Imperial ride III seems to focus on comfort and mute performance, which is very consistent with my requirements. The tire specifications are also in line with my vehicle. Check everything, ok, get ready to start.
During the period, the landlady moved the parking space and came to the leftmost working position, which could be lifted directly without a Jack.
Let’s take a picture of Pirelli, who has been in service for nearly 2 years and impressed me.
Of course, the anti-blowout tire is not useless, the tire wall is relatively thick, so there is nothing to worry about. That’s why I got careless. I scraped both the hubs of the rear wheels.
The new and old tyres first take a group photo, perspective principle, so I feel that the Goodrich III that I am going to change into should be a bigger circle, but it is not.
The little master who changed the tire for me said that from the tread pattern, we can also see that the mute performance of the III tire is definitely better than that of my original tire.

I feel that the tire wall of Goodyear Imperial bus III is also quite thick, which is as good as the explosion-proof tire of the original car.
To drive dry, first lift the car.
Then the two masters helped me operate it quickly, taking off the wheel first. This is the rear wheel, the light near the door is better, the picture is relatively clear.
While talking, the two rear wheels came down, and the rear brake disc felt so small that the single piston brake did not look.
Another master is helping me unload the front wheel. This master is dressed in a more standard way. It looks like Goodyear’s clothes.
The front brake is relatively thicker, and the single piston is still unseen.
This process is more unbearable to see, when picking the tire almost flattened the tire, although the mechanized operation is fast, I feel quite hurt the tire.
Then the young master painted a layer of grease on the contact between the side of the new tire and the hub, which is estimated to make the contact between the hub and the tire better.
The process of loading the tire to the wheel hub is similar to the process of picking the tire, and I can’t bear to watch it. I was worried that the wheel hub would be scratched, but then I found out that I was too worried. The young master protected the wheel hub and the wheel hub was not scratched at all.
This little master really works very attentively. Generally speaking, after changing the tire, he only does the dynamic balance of the front wheel. Today, he gave me dynamic balance for all four tyres. Praise and thank you again.
Make a comparison before you get in the car. It does feel that the Goodyear imperial ride III is softer, which should be one of the reasons for its better comfort and mute performance. Of course, this is inseparable from the more advanced scientific and technological performance of Goodyear tires brought about by the investment in scientific research.
With the blessing of the air pump, the tires are inflated and get on the bus in one go. Put on new shoes, love the car seems to be a lot of arrogance.
After the vehicle landed, the little master also fastened the screws for the four wheels, which made me feel at ease.
Before leaving the shop, the landlady also came forward to remind me that my car was monitored with tire pressure and might need to do a tire pressure reset. Later, I found that there was no need to do it, and everything was normal for tire pressure monitoring. In short, it was a very satisfactory tire change experience.
Fourth, the experience of the new fetus
This generation of 5 series can be said to be mixed, with mixed feelings. The model is what I need, with a certain degree of sports, although the rear suspension has been reduced, but to cope with daily, it is still quite fun to drive. At present, it has driven more than 16000 kilometers, and the car environment is relatively fixed. The roads in the urban and rural fringe areas are mainly driven, and the highway will also be there on weekends and holidays. Although there is an oil-burning problem with the B48TU engine, and although BMW has been reducing its configuration, it should be said that the 5-Series is passable in the three major parts of the same class of BBA models. At the beginning of the lift car, I felt that the sound insulation of the whole car was quite good, but the only thing I was not satisfied with was the tire noise of the factory-equipped Pirelli P7. Because of the nature of my work, I went to work earlier, and the road was quieter at that time. At that time, the road feeling of this explosion-proof tire was hard, and the characteristic of excessive tire noise was highlighted. On several occasions, when changing lanes on viaducts and highways, the wheels still twisted, but it was later found that it was because of the rain, and the tires skidded slightly when crossing the driveway. I thought that maybe the 275 rear wheel of the standard shaft version would be more robust, and I had a little regret for not buying the standard shaft version.
The second day after the replacement of the Goodrich III was Sunday, so I drove to my hometown. Because there is nothing wrong, so I have time to experience this new tire carefully. During this period, it passed the elevated road, the old highway in the urban-rural fringe, or the old cement road in the countryside, but not the mud road (in other words, it is difficult to find the dirt road in the countryside today). He even walked a short section of wading road when he passed a fish pond. It should be said that in addition to the highway, I have almost experienced several road conditions that I often encounter in the future. The most direct feeling along the way was that the fetal noise that I could not bear was finally gone, and there was finally a kind of stillness walking in the autumn color. The III generation is really excellent in mute performance, because of the new tire, the performance in this aspect should be better after running-in.
After 24 years of driving, I dare not say how familiar I am with the car, and I have at least changed several sets of tires. I can’t come up with the scientific and accurate test data, but I still have the most intuitive feeling. Whether driving at the speed of 80km/h or so on the viaduct, or on the urban-rural fringe road like the one pictured above, the most direct feeling of this set of III generation is that the shock absorption performance of the car seems to have been improved, and the contact between the wheel and the ground is no longer the kind of dry, hard contact feeling, so the improvement of overall comfort is obvious. I have the feeling that I am used to wearing hard leather shoes and changing them into sneakers. Personal feeling is more in line with the BMW 5-Series this kind of partial movement attribute setting, I believe it will also be helpful to the handling performance of the whole vehicle.
When wading through this small section of the fishpond, because we often walk, the road conditions are more familiar, and there is only a thin layer of water on the road, so the speed of the car has not dropped, even though this section of the road is still at a turn. Inadvertently, it also gave me an understanding of the performance of the III generation on slippery roads. It has the same excellent grip performance as the Imperial Rider 1 in my other car, which gives you confidence. This is especially important for rear-drive cars like the 5 Series, where I have witnessed several accidents in which luxury cars in underground garages skidded and hit walls.
The III generation has such an excellent performance on wet and slippery roads, I think it can not be separated from its scientific design. Looking at the tread pattern at this time, I have some understanding of the words of the young man who changed my tire yesterday. Indeed, this is a tire that takes into account both comfort and grip performance.
What impresses me most is that after entering the village, when the III generation walked on such a dilapidated cement road, its comprehensive strength was fully demonstrated. First of all, there is almost no difference in comfort with the asphalt, and secondly, the contact between the tread and the ground will not produce much murmur, and the silent performance is still excellent, which will certainly not affect your mood of driving. I specially drove my car on the oldest concrete road on the right side, and the effect was still very satisfactory.
Said that at the end,
The above is my original factory equipped with endurance P7 explosion-proof tire to replace the III generation, as well as the initial experience of the new tire, finally, I have a few ideas for you.
1. The anti-blowout tire of the original factory is certainly not useless, you can choose to “go or stay” according to your own preference.
2. There is a replacement cycle for tires. Don’t forget to check them. Of course, for a better driving experience, it doesn’t hurt to change your favorite tire early.
3. There is no need to worry about whether the tire is the original tire or not, and the whole machine factory does not produce tires. The specification is right, the performance is right, of course, you can also consider the performance-to-price ratio.
4. As far as I am concerned, the III generation meets my requirements for mute, comfort and grip performance, and it seems to have a good performance-to-price ratio.
