[Red Maple is like Fire] Tire maintenance and knowledge

September 24, 2024

The tire is the only accessory that comes into contact with the ground, which carries the weight of the whole car body. It can be said that it is a very important safety part. Today, I will talk to you about the tire.
Let’s talk to you about the type, air pressure and maintenance of the tire.

Ours? Do you want to wear a coat or two for a brilliant salary? In 2008, the current mileage is 31000km. When I do maintenance, I will also observe the wear and tear of the tires. Of course, I will take care of them myself in my spare time. Shi Mu hemorrhoids? What are the staff members? Menai? Drag? ? / mtip]

The four tires of the whole car are all original. Fortunately, the tires have not been nailed or damaged in the past three years.

So far, there is no big problem with the tires, that is, the steel rings are not without dillydallying, and later painted the four steel rings of the original car. (personal preference, don’t spray if you don’t like it)

It’s a little off the subject, so let’s get back to the topic of tires.

When we buy a car, we can judge the approximate production date of the car from the tires.

There are tires on the year of the tire and production schedule, if there is no tire date, it is doubtful whether the tire has been refurbished. The red circle in the picture above marks the date of production.

The above picture (49 16) shows the production date of the tire, with the first 49 representing 49 weeks (497 million 343 days) and the latter 16 representing 2016. From this, we can judge the approximate production date of the vehicle. In addition, compare whether the production dates of the remaining tires are the same, if not, this car tire will be doubtful.

In addition, when we change the tire in the later stage, we can also use this method to judge the date of the tire. The tire belongs to the rubber material. Do not be tricked into buying the old tire by the tire shop (meaning that the year is longer). In addition, I would like to remind you that this logo can also be refurbished, so when we change the tire, we must choose a regular store to buy, do not be cheap, safety parts can not be careless.

There is also a nameplate on the vehicle indicating the production date of the vehicle, (49 16) 343 days in 2016, which is consistent with the production date of the vehicle, from which the originality of the tire can be judged.

? The 5-inch steel ring matches the tire of 195/65R15 91H. Take my tire as an example:
195: tread width (mm)

65: flat ratio (tyre height, tyre width)

R: Meridian structure

15: ring diameter (inches)

91: load index

H: speed cod

Some riders only pay attention to the size model, often ignore the load and speed model, the price difference will be very big, so it is suggested that everyone try to change the tire to choose the same type of tire. The tire size designed by the designer of the original factory is the most comfortable choice for the whole vehicle.

After talking about the tire model, let’s talk about the choice of tire pressure.

It is believed that the tire pressure of many riders is the same as 2.5, but they do not realize that this is a great hidden harm to the tire.

In fact, car manufacturers will label the most standard air pressure value of our vehicle tire on the car body. do not see that the tire feels a little flat and say that the tire is flat. We should learn to add the most appropriate air pressure value to the tire to increase the comfort of our vehicles.

It is recommended that you prepare a tire pressure gauge with the car so that we can have a more accurate tire pressure value.

If you have an idea, install a built-in tire pressure test, it will be more intuitive to see the tire pressure.

The tire pressure should be the same, when the tire pressure on one side is too low, it will affect the driving comfort and deviation of the whole vehicle, and the service life of the tire will be affected for a long time.

With the change of seasons, we also need to learn to adjust the appropriate air pressure, tires are rubber parts affected by thermal expansion and cold shrinkage, properly increase the air pressure in winter, if not properly increase the air pressure, it will affect the tire wear and vehicle fuel consumption. Riders who are equipped with tire pressure monitoring will have a very intuitive feeling of the change in tire pressure.

When the tires come into contact with the ground, we always avoid being accompanied by pebbles, which will also affect our tires, so we should learn to remove these stones from the tires in time.

I believe everyone is familiar with this artifact, cleaning tires and stones.

The pebbles on the tires will affect the drainage of the grooves of the tires. If the sharp stones are not cleaned in time, it will affect the service life of the tires. So we should learn to clean up the stone in time.

Finally, we have to regularly check the wear and aging of tires, under normal circumstances, the service life of tires is about 4-5 years, but also according to the road we usually drive to determine the service life of tires.

The red mark in the picture above is the sign of the tire safety line. When the tire is worn and parallel to the safety line, the tire must be replaced in time to avoid some problems such as a flat tire.

There are also some riders whose treads are very deep, because the car runs very little but for a long time, and the tires are aging, so we also have to change the tires according to the aging of the tires.

The spare tire is a part that we often ignore, and many cyclists may forget its existence.

Spare tire means spare tire, so it will be troublesome when the spare tire is flat, so we usually have to check its air pressure and aging degree. But do not use the spare tire as a common tire, the size of the spare tire is often one size smaller than the common tire, and its driving speed is much lower than the common tire.
