I feel like a replacement is needed in a year to two years. Of course, the aluminum alloy valve will be a little better, because the quality of this valve will be a little higher, and the durability will be a little better.
-
It is better to replace it once in more than three years, so as to better ensure safety. The rubber is a little better, this thing has a certain elasticity, which can be more safe.
-
It takes half a year to replace it, and the aluminum alloy valve is better, because it is particularly wear-resistant, and it is not easy to break.
-
It needs to be replaced in half a year, and it should be determined according to the actual situation, and according to the situation of the tire, you can choose the alloy one, which is better processed and very strong.
-
Since the valve is made of rubber, it will inevitably age, and the valve body will gradually crack, deform, and lose its elasticity. And when the vehicle is driving, the rubber valve will swing back and forth with centrifugal force to deform, which will further promote the aging of rubber. Therefore, the tire valve needs to be replaced in 3-4 years, which is about the same as the service life of the tire, and it is recommended to replace the valve when replacing the tire.
In terms of durability, aluminum alloy valves will be better, because aluminum does not age, while rubber valves will age over time; But from the point of view of use, the rubber one will be a little better, because the rubber valve is one-piece molded and has better air tightness, and the aluminum alloy base has threads for installing built-in tire pressure monitoring.
Car owners who are particularly concerned about the market will find that the vast majority of cars on the market use rubber valves. According to the relevant experience of the industry, there is basically no big difference between the rubber valve and the aluminum alloy valve in the angle of use, and the seals are made of rubber. Therefore, rubber valves are relatively more versatile and can be applied to most wheels, while aluminum alloy valves are mostly replaced at a later stage.

There are usually a lot of numbers and letters on the tires, and these numbers and letters represent different meanings. Most tires have the DOT logo, the tire DOT is the meaning of the United States Department of Transportation certification, usually followed by a string of numeric letters, which represent the origin information of the tire and the factory**, the last four digits are the production date of the tire. The first two represent the number of weeks of production, and the last two represent the year of production.
In addition, we can also see that there are many numbers and letters on the tires, some are tire brands, M+S means that mud and snow are applicable, some tires will be marked as M S, M&S or MS, and some are marked All, that is, the same tires in all seasons. There are also a series of numbers and letters similar to 195 60 R15 88T, which identify the specifications of the tire
195: refers to the tread width of the tire, which means that the tread width of this tire is 195mm.
60: refers to the flat ratio of the tire, not that the tire thickness is 60mm, but that the flat ratio of the tire is 60% (flat ratio = tire height and tire width 100%).
r: refers to the type of tire, which means that the tire is a radial tire.
15: Refers to the wheel size, this tire is suitable for 15-inch wheels.
88: refers to the load index of the tire, that is, the maximum load of the tire, the maximum load of this tire is 560kg.
t: refers to the speed class of the tire, that is, the maximum speed of the tire, the maximum speed of this tire is 190km h.
In addition to this, there are also numbers on the sidewall of the tire to represent the performance of the tire
The wear resistance index Treadwear reflects the wear resistance of the tire, the higher the value means that the tire is more wear-resistant, and it also means that the hardness of the tire is greater, the worse the comfort, and vice versa. Generally, the wear resistance index is moderate at 280-320. The wear index of the tire is 320, which indicates that the comfort of this tire is better.
traction represents the traction index, and the following letters represent the strength of the grip, from high to low, AA, A, B, C. AA indicates that the tire has very strong traction.
temperature represents the heat generation index of the tire, and the following letters indicate the heat generation level of the tire, and the heat generation level of car tires from high to low are A, B, and C. The heat generation level of this tire is A, which means that the high temperature resistance is excellent.

According to the relevant experience of the industry, there is basically no difference between the rubber valve and the aluminum alloy valve in the angle of use, and the seals are made of rubber. Rubber valves are more versatile, can be applied to most wheels, and are more anti-theft. The base of the aluminum alloy has threads that can be equipped with built-in tire pressure monitoring, and the car with tire pressure monitoring is estimated to have to use alloy valves, and the alloy valves are more like they are born for the installation of tire pressure monitoring, and the rubber valves do not have built-in tire pressure monitoring installation threads.
Each has its own benefits, choose according to your needs.
-
The valve of the car tire is probably better than the aluminum alloy material, after all, it is more high-grade and has a longer service life, however, the advantage of rubber is that the cost is relatively low.
-
It's better to use rubber, every time you change a tire, you ask the tire shop to give you a free replacement of the vacuum head, absolutely OK, our shop has always done this!
-
Aluminum alloy is better, compared with rubber nozzles, aluminum alloy is not easy to age.
-
Personally, I feel that the steel is good, and the rubber is easy to age.
-
If you don't drive aggressively, there is basically no difference.
It's just that the life of the plastic is low, and it will deteriorate and brittle.
The life of the metal is mainly reflected in the sealing fluid.
It will deteriorate over time, but the life span is much longer than that of plastic.
-
When replacing new tires, you must replace the valves with new ones. This is because the valve is a rubber product and has the problem of aging cycle. When a new tire is replaced, although the valve does not see the problem at the time, the valve may deteriorate prematurely during the life cycle of the new tire, causing a safety hazard.

How often to replace car tires According to the wear and tear of the tires, according to the shelf life of the tires: there will be four digits on the sidewall of the tires indicating the date of manufacture of the tires, the first two represent the number of weeks, and the last two represent the year. The use of tires should generally not exceed 3 years, and the mileage should not exceed 60,000 kilometers.
While a little over the years and mileage doesn't hurt the big picture, the cold temperatures in the winter and the rain in the summer can stretch the wet grip and dry handling of the tires.
Pay more attention to the sidewall: As the tire rubber gradually ages, the sidewall of the tire will appear to be deeply wrinkled. However, as long as the sidewall of the tire has not been hit and the cord has not been broken, it can continue to be used.
The triangular logo on the sidewall of the tire can help the owner find a protrusion in the groove of the crown of the tire, which can determine the actual wear limit of the tire, which should be greater than millimeters. Choose a reasonable time to replace tires to determine whether a car needs to replace tires, regularly check the vehicle's tire wear mark baseline, when the tire wear degree on the outside of the tire reaches the baseline of the replacement, it means that the tire needs to be replaced.
-
The valve valve of the car tire should be made of aluminum alloy. Because the chemical properties of aluminum alloy are relatively stable and the service life is long.
-
TubelessIf the valve is lost, you can go to the repair shop to reinstall it or change the tire directly, because you can't operate it yourself.
The function of the valve is to inflate and deflate the tire and maintain the seal after the tire is inflated. Ordinary valves are composed of three main parts: valve body, valve core and valve cap.
Types of valves:
1. According to the use: bicycle valves, motorcycles, electric vehicle valves, car valves, truck bus valves, agricultural engineering vehicles.
valves, special valves, etc.
2. According to whether there is an inner tube: inner tube valve T and tubeless valve.
3. According to the assembly method: screw-on valve, compression valve and snap-on valve.
-
During the use of the vehicle, if the tires are seriously worn, the tires need to be replaced in time. Because tires carry the weight of the entire vehicle, if there is a slippage, it can lead to accidents. So do you need a valve valve to change a tire?
Changing tires requires a valve valve. Because the valve is the same as the wheel.
The part that comes into contact with it is plastic, which is a fragile product, and if it is used for a long time, it will deteriorate and lose its elasticity. If you replace the tires without replacing the valves, the vehicle will leak during driving, so it is recommended that the owner replace the valves every 3 to 4 years, regardless of whether the tires are not replaced.
In addition, car owners should pay special attention to the quality of valves when purchasing valves. The valve can be placed in water, if there is a bubbling phenomenon, it means that the sealing effect of the valve is not good, and it is more likely to be damaged and leak when used. If there is no bubbling phenomenon in the water of the valve, it means that the quality of the valve is in line with the regulations, and the owner can use it with confidence.
-
Depending on the actual condition of the selected valve, it is up to the valve to be replaced at the time of the tire change.
Rubber valves: Since the valve is an inevitable aging problem of rubber material, the valve body will gradually crack, deform, and lose its elasticity. When the vehicle is moving, the rubber valve will also be deformed with the centrifugal force swinging back and forth, which will further promote the aging of the rubber.
Generally speaking, the life of the rubber valve is 3-4 years, which is not much different from the service life of the tire, so the rubber valve is replaced when the tire is replaced.
Metal valves: In order to avoid the aging problem of rubber valves, metal valves have gradually appeared on the market, and steel valves are one of them. Due to the change in material, the steel valve is much higher than the rubber valve, and the service life of the steel valve is two to three times that of the rubber valve, which is mainly due to the fact that the metal material is not easy to be oxidized, and the metal valve also has better air tightness.
Of course, the ** of metal valves is much higher than that of rubber valves.
In addition, the valve made of metal is sometimes abnormally aged or deformed due to impact, corrosion, etc., and the valve also needs to be replaced by the valve. Therefore, when maintaining the car and tires, it is also necessary to check the valves.
-
Not necessarily, if you want to change, you can change it, and by the way, you can add 5-10 yuan (5 yuan for rubber valves, 10 yuan for aluminum alloy valves). Generally, the valve is replaced when it is aging or the valve is leaking.
