When the wheel outer diameter (tire tread outer diameter) is unchanged, increasing the wheel hub diameter will make the "bead thinner"
Tires are made of rubber and have elasticity.
Thick tires can absorb the * * * force from the road when the car is running, which can play a role in shock absorption and increase ride comfort.
However, tire resonance is easy to occur at high speed, which affects the stability of suspension; Similarly, when cornering at high speed, the flexible tire will be deformed under the action of "centrifugal force" and "roll" of the car body, which will affect the grip of the wheel.
Thin tires, on the other hand, have the opposite advantages and disadvantages to thick tires, which can provide a good sense of road for racers and help them to play.
Most of the cars with enlarged hub diameter are racing cars or sports cars, and its excellent suspension system can greatly eliminate the disadvantages caused by tire thinning.
For racing sports cars, the most important thing is the high-speed performance of the car, while the requirements for comfort are relatively less important.
Question 2: What's the difference between car tire sizes? It mainly depends on the tire size, whether it is tire width, flat rate or hub diameter. The tire size is 360.
Question 3: What's the difference in the size of car tires? The bigger the first tire is, it is also the drive shaft connecting the tire. Every time the tire turns, it runs farther. The larger the second tire, the larger the contact area with the road surface, which will enhance the grip of the vehicle. The bigger the third tire, it means that the fuel consumption of the whole vehicle will increase. This is because big tires need extra power to drive.
Question 4: Is there any difference in tire size? The difference and emphasis is not on the wheel hub diameter, but on the wheel hub diameter with tires. Generally speaking, manufacturers produce the same car with different configurations, and sometimes the wheels with low configurations are smaller, but the flat rate of tires will also increase, and the final gap is not big. The same is true for high-profile models with individual large wheels. Larger wheels will increase the ground clearance and improve comfort, and there is generally no difference in operation. If you change a tire with different sizes from the original factory, the power and fuel consumption will change, and the speedometer will be inaccurate, but the difference will not be too great. Most people can adapt, but novices may not feel it. If LZ pays more attention to the driving experience, it is recommended that you have Luoufeng tires, which are very comfortable and have good handling. Moreover, they are holding their first anniversary recently. The tire wear exceeds 1mm within 2 weeks, and it is quite awesome to replace it for free.
Question 5: What are the advantages of automobile tires? The larger the tire diameter, the larger the ground clearance, that is, the higher the chassis, and the better the vehicle passability. The tire width is large, the contact area with the ground will be large, the comfort can be improved, the pressure on the ground is small, the tire can walk on soft ground, and it is suitable for off-road use. In addition, the contact area with the ground is large, and the braking effect will be better. However, due to the large contact area with the ground, the friction resistance will also be hit, so the fuel consumption will be relatively large.
Question 6: What are the disadvantages and advantages of increasing tire size? Ask the Great God to buy the same tire size as the tire assembled by the original car. Therefore, one of the shortcomings is the resulting risk, which needs to be borne by yourself.
Question 7: What are the advantages of the wheel hub size? The size of the hub is divided into diameter and width, and the former is generally valued. Due to the limitation of wheel arch and wheel arch, it is necessary to reduce the flatness after replacing the wheel hub to ensure that the tire circumference (diameter) is close, which will not destroy the torque and can be installed smoothly. The biggest advantage of changing the big wheel hub is that it has a strong sense of * * *, but it should be more practical with wide tires. Generally, large wheels will increase the tire width and even become negative wheels, which are widely used in off-road vehicles. Secondly, the tire flatness becomes smaller, the heat generation rate is low at high speed, and the air pressure changes little. Therefore, cars with large wheels, wide tires and low flatness pay more attention to road performance. On the contrary, off-road vehicles like practical high-level tires, even with central air pressure adjustment, so as to climb over vertical walls or cross sand to reduce pressure. Look at the rear tires of the agricultural tricycle. They are very flat. There are also cars with large wheels and high flat tires to increase the tire diameter. Generally, off-road vehicle players are used for high chassis, which helps to improve the field ability, but it also needs to be modified at the same time, such as suspension and differential lock.
Question 8: What are the advantages and disadvantages of large diameter wheels? Many people want to upgrade their wheels to increase the fun of cars. But in addition to ornamental, hub upgrade has many other functions. Now tell you my understanding:
1, there are two kinds of hub upgrades. The first is to upgrade the original iron wheel hub to aluminum alloy wheel hub or light aluminum alloy wheel hub without increasing the wheel hub size. The second is to increase the diameter of the hub, so that the tire becomes flatter and more closely connected with the valve and some racing cars.
2. What are the advantages and disadvantages of these two wheel hub modifications? Now let me explain it to you.
The first modification: first of all, talk about the characteristics of iron rims. The iron rim is relatively heavy, which increases the weight of the car itself and is easy to rust. The biggest drawback is poor roundness. Even if it doesn't open, it will deform after a long time. However, the aluminum steel ring itself is relatively light in weight and not easy to rust. In the casting process, it can be very round and is not easy to deform after casting.
Under the condition of not changing the rim size, upgrading the aluminum ring with iron ring has the following advantages: 1, reducing the self-weight of the vehicle and saving fuel (replacing an aluminum ring with the same size can reduce the weight of your vehicle by 1 to 2kg, and replacing four can reduce the weight by 6-8kg, so you can save fuel from 500 yuan to 800 yuan according to the mileage of 30,000km a year). 2, it is not easy to rust and deform, and the safety is improved because the rim is not round, which will affect the air tightness. 3. I don't need to say more about beauty.
The second upgrade is to increase the hub diameter, which will change many properties of your original car and make it more professional. But there are advantages and disadvantages. The main advantages are as follows: 1, with the replacement of large-size rims, the tires become larger, the grounding area increases, the driving is more stable, and the driving safety is improved; 2. Because the flat tire rate is reduced, the power transmission is increased, and the handling is improved accordingly; 3. Increase ground friction and shorten braking distance. 4. The vehicle looks imposing and dazzling! Disadvantages are: 1, which will consume more fuel correspondingly; 2, expensive, usually upgrade the size of the wheel hub, the tires must be replaced together, these two pieces add up to a lot of expenses. 2, the shock absorption effect will be weakened and the comfort will be discounted. In my experience, if you don't take the rugged mountain road and patronize various construction sections, you can still do it, otherwise don't raise the wheel hub too much. Unless you change the damping accordingly.
Question 9: What's the use of talking nonsense about the large tire size on the first floor?
Is the brake good? It's just that the grip is better than that of a small wheel diameter.
The larger the tire size, the greater the angular momentum and the greater the braking torque required.
I really haven't found this kind of problem on the Internet.
Let me combine my personal experience.
My home is in Yichang, and I built the Three Gorges Dam. I remember when I was a child, I went to the Three Gorges site and was intercepting water.
There are many cars with big wheels on the construction site. My father told me that they were imported from Germany, with a maximum load of 100 tons. The wheel is as high as two people. There was a picture of me not as high as the tire rims.
So let me summarize.
1, can bear greater pressure, which is the force per unit area. The tire has large size, strong compression resistance and heavy load capacity.
2. Off-road performance These cars on the Three Gorges site travel back and forth on the gravel mountain road all the year round. The radius of the physical sphere determines the height of the wall that can be crossed. The larger the tire size, the higher the load that can be crossed.
3. Stability The reason why elephants are more stable than giraffes is that elephants have large soles and large tires.
4. The bigger the tire size, the stronger the wading performance when passing through a puddle.
5. Climbing ability is actually a part of off-road performance. If the tires are too small, the front of the car can easily hit the slope.

Hehe, I hope it will help the landlord.
You seem angry upstairs.
What do you mean, "copying other people's things makes you feel great?"
I answer questions wholeheartedly, using my own personal experience. If this is plagiarism, can you find it?
The landlord is asking what is the use of large tire sizes and adding these things? "The braking distance of ordinary tires is definitely much longer than that without sudden death." Where did I write about sudden death? Before I studied physics and watched F 1, I used to be the bar owner of F 1. I know more about cars than you.
As for the wheel diameter with large wheel diameter, you feel strongly about the road surface when driving, but it is not as comfortable as the wheel diameter with small wheel diameter. On the contrary, I don't need to say that the wheel diameter is small. Is this sentence reasonable?
It's just that the reverse large wheel diameter absorbs the road vibration better than the small wheel diameter, and the vibration feeling is smaller. On the contrary, the vibration of the small wheel diameter is greater. People who ride 14 inch folding bicycles can feel strong vibration and feel uncomfortable when crossing uneven roads.
