Pros and cons of large diameter hubs Advantages and disadvantages of hub size

To be honest, the general civilian small displacement car is replaced by large wheels just to look good. It is useless to blindly increase the flattening rate. The flatter the tire, the more resistant it is to lateral deformation, but many people think that grip also improves, which is a misconception.

The ground contact area of the tire itself remains the same, and it is impossible to obtain greater grip. The purpose of anti-lateral deformation is to maintain good handling when cornering at high speeds.

Although large wheels can accommodate larger brake discs, the domestic modification business has just emerged, and there are not many people who spend a lot of money to change brake discs. And because the technical level is uneven, the modification at the technical level still does not account for the majority. People generally want to have a stylish appearance.

The wheels of a sports sedan or sports car are large, but there is also a huge wheel arch to echo them, which can accentuate the muscular feel of the car. If you just change the big wheels, many cars will look slightly incongruous. And it does lead to an increase in fuel consumption.

Modification of oversized wheels will destroy the driving and transmission stability of the original car, increase transmission loss, improve fuel consumption, due to the increase in the circumference of the tire tread matching the large-size wheels, the mileage record and speedometer are no longer accurate.

Modifying the wheels, violating the traffic law, is an illegal act, and it is fined according to law and ordered to be restored to its original state. Destroy the stability of the original car and bring potential safety hazards. The annual examination is not passed, and the annual examination cannot be completed.

In the event of a traffic accident, the insurance claim is to repair the wheels of the original car, and if it is repaired to a modified state, the cost will be borne by yourself.

1. Illegal modification of the vehicle refers to the modification of the appearance, power system, transmission system and braking system of the vehicle beyond the design load capacity and function of the original vehicle that is not permitted by national laws and agreed by the manufacturer. This includes the act of replacing critical components.

2. According to Article 16 of the Regulations on Motor Vehicle Registration of the Ministry of Public Security:

Small and micro passenger vehicles are equipped with front and rear anti-collision devices; Freight motor vehicles are equipped with draft shields, water tanks, tool boxes, spare tire racks, etc.; Increase the interior decoration of motor vehicles.

All three of these conditions are allowed. In addition, changing the brand, model, engine model of the motor vehicle, changing the appearance of the registered motor vehicle and relevant technical data are all illegal modifications.

3. Article 10 of the "Provisions on the Registration of Motor Vehicles" stipulates that if a registered motor vehicle needs to change the nature of use, body color, body or frame, etc., the owner of the motor vehicle shall apply to the vehicle administration office at the place of registration to change the registration.

4. Article 16 of the Road Traffic Safety Law of the People's Republic of China, Paragraph 1 stipulates that no unit or individual shall assemble a motor vehicle or change the registered structure, structure or characteristics of a motor vehicle without authorization. Without the permission of the public security traffic management department, unauthorized modification of the motor vehicle chassis, engine, suspension, transmission system, direction system, tire hub, headlights, body color spraying and appearance structure, as well as the relevant technical data of the motor vehicle and the announcement data of the competent department of motor vehicle products are all modifications.

5. The announcement data includes: vehicle steering form, body size and size, fuel type, number of leaf springs, wheelbase, number of tires, tire specifications, total mass, approved load quality, environmental protection standards, displacement power, axle number and vehicle appearance.

The wheels are bigger, the tires are bigger, maybe your car's odometer is not accurate, and maybe you may be speeding a lot (the odometer is not speeding, but it is actually speeding).

Is it better to have a big wheel or a regular wheel? Do you know the pros and cons?

Many people want to upgrade their wheels to make their cars more enjoyable. But in addition to ornamentality, there are many other features of the wheel upgrade, and now I will talk to you about my understanding:

1. There are two kinds of wheel upgrades, the first is to upgrade the original iron wheels to aluminum alloy wheels or lightweight aluminum alloy wheels, but do not increase the size of the wheels. The second is to increase the diameter of the wheels to make the tires flatter and closer to what some racing cars look like.

2. What are the pros and cons of these two wheel modifications, now I will explain them to you.

The first modification: first of all, let's start with the characteristics of the iron steel ring, the iron steel ring is heavier, which increases the weight of the car itself, and is easy to rust, the biggest disadvantage is the poor roundness, even if it is not opened, it will be deformed after a long time. However, the aluminum steel ring itself is relatively light in weight, and it is not easy to rust, in terms of casting technology, it can be very round, and it is not easy to deform after casting.

Without changing the size of the rim, the iron rim upgrade aluminum rim has the following benefits: 1. Reduce the weight of the vehicle, which can play a role in saving fuel (replacing one aluminum rim of the same size can reduce the weight of your car by 1 to 2 kg, and replacing four can reduce the weight of 6 to 8 kg, so according to the mileage of 30,000 kilometers a year, you can save 500 to 800 yuan of fuel). 2. It is not easy to rust, not easy to deform, and the safety is improved, because the rim is not round will affect the air tightness.

3. I don't need to say much about beauty.

The second upgrade is to increase the diameter of the wheels, so that many of the properties of your original car will be changed and more professional. But there are pros and cons. The main benefits are as follows:

1. Replace the large-size wheels, the tires will also increase, increase the grounding area, make the driving more stable, and improve the safety of driving; 2. Because the flattening rate of tires is reduced, the transmission of power is increased, and the handling will be improved accordingly; 3. The ground friction is increased, and the braking distance is shortened. 4. The vehicle looks imposing and dazzling! The disadvantages are:

1. It will cost more fuel accordingly; 2. ** Not expensive, usually upgrade the size of the wheel, 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 rugged mountain roads, it's okay not to patronize various construction sections, otherwise, don't raise the wheel hub too much.

Unless you change the shock absorbers accordingly.

I don't know about this, but if you want to change the wheel, you can go to Chuangming to take a look, it feels good.

Advantages of hub size:

Widening the width of the tire and changing the diameter of the tire will increase the ground contact area of the tire, that is, increase the grip of the car, which has a great impact on the acceleration, braking and driving stability of the car. If you start with a car without widening the tires, you will have to flex the tires, but if you widen the tires, you will reduce this, making the car's power delivery more direct and efficient, which is of course ideal.

Although the widened tires bring stronger grip, it is necessary to consider whether the engine power is sufficient, whether the output shaft can withstand such a strong torque, and whether the gears of the axle can withstand such a large amount of stress before modification.

Hub size disadvantages:

Changing the diameter of the tire, in fact, is allowed within a certain range, some manufacturers will also provide different specifications of tire rims for the owner to choose, this situation has little impact on the car, and their own modification may not be so thoughtful.

The result is a serious inaccuracy of the tachometer, a serious inaccuracy of the fuel gauge, an inaccuracy of the mileage, and a change in the circumference of the tires that has a great impact on the car, but the electronic components cannot detect it.

Precautions for purchasing wheels:

1. Don't try to buy fakes cheaply.

The modification of the wheel hub is a more important step in the modification of the car, whether it is the appearance of the modification or the improvement of handling performance, the wheel hub has played an important role in it, a high-quality wheel, after the rigorous production process and strict inspection, to ensure that its personality parameters are qualified.

2. Choose the right wheel hub correctly.

The role of the wheel hub to enhance the appearance is more obvious, but when choosing the wheel hub, every detail must be taken into account, the various parameters of the wheel hub will affect the use of the wheel hub and the vehicle, the PCD value is incorrect may not be able to install normally, the ET value not only affects the installation and use, but also may affect the future upgrade and modification.

3. Ensure that the wheel hub is installed correctly.

Modified wheel hub should pay attention to the size of the diameter of the center hole, if this size is smaller than the original size, naturally can not be installed, but if it is larger than the original size and no comparative measures are taken, it will cause the vehicle to appear different when driving, resulting in abnormal noise and shaking of the vehicle, and in serious cases, it will directly affect the safety of the vehicle.

1. Advantages, excellent handling performance, the bracket of the large hub is large and strong enough, the control feeling of the large hub is also excellent, and the power transmission is excellent;

2. When the car turns the road, the tilt amplitude is smaller, and it is easier to corner, the larger the hub area, the stronger the support of the hub to the tire, the more direct the friction on the ground, and the grip is easier to output from the inside to the outside, making the tire more stable;

3. Beautiful appearance, many luxury cars will use large wheel tires, which are stylish, luxurious and face-saving;

4. Disadvantages, poor shock absorption, the larger the hub, the smaller the relative tire, the smaller the tire, then the tread of the tire will be thinner, and the gas in the tire will be less, then the buffer of the tire will be weaker, and the shock absorption effect of the tire will be poor;

5. High fuel consumption, the wheel hub is a metal product, because the metal mass is larger, so the wheel hub is heavier, and the large wheel means that the tire will be heavier, and the weight of the large wheel will consume more oil. The fuel consumption of large wheels will be relatively high.

The bigger the wheels, the wider the car, and the more stable it will be.

The advantages, there is no doubt that the disadvantages of thin tires with large wheels become its advantages. It should be better in terms of driving comfort. And the fuel consumption of these cars is generally not very high. Therefore, many people still like it.

More durable, you can find this type of car wheel tires, no matter what road surface, can run, especially mountain roads, very durable. Strong collision avoidance. It doesn't matter if it's a nail stab. You can continue to open.

The disadvantage is that in the grip of car tires, it is inferior to large wheels and thin tires. And if you don't brake in time, this type of car is prone to rear-end collisions, because the braking is a little less efficient. Therefore, we need to have a relatively long distance to achieve an overall improved braking effect.

But as long as we can drive car owners who can be skilled in driving technology, it doesn't matter.

It can be seen from the above points. Small hubs and thick tires still have more advantages in terms of advantages. There is also a disadvantage that one does not look beautiful and does not appear so tall. But driving safety comes first.

In general, it still depends on the use of the car. If you often drive on highway or city roads, large car wheels are good for thin car tires. If you travel more on the country road, it is good to have thick car tires for the car wheels.

The advantage of large wheels is improved safety performance; The disadvantage is reduced comfort and shock absorption. Big advantages: The biggest benefit of large wheels is the improved safety performance, because the flatness of large wheels is small, the heating rate is low at high speeds, and the air pressure changes are small.

Therefore, the overall performance of the car with large wheel lift, wide tires and low flatness will be improved. And the car is a big help to improve the capacity of the site. Disadvantages of the wheel:

Due to the thin tire wall, tires with large hubs often have weak resistance to external impacts, and are easy to bulge when walking on some bumpy roads, and may even directly cause a puncture when encountering sharp objects. In addition, almost all large-sized wheels are heavier than smaller-sized wheels, and thin tires cannot balance this weight, which will lead to an increase in unsprung weight, which can negatively impact fuel consumption, handling, and comfort. That is, a large hub will greatly reduce the shock absorption and comfort of the car.

Advantages and disadvantages of the size of the hub: 1. Advantages, excellent handling performance, the bracket of the large hub is large and strong enough, the control sense of the large hub is also excellent, and the power transmission is excellent; 2. When the car is on the bypass road, the tilt amplitude is smaller, and it is easier to corner, the larger the hub area, the stronger the support of the hub to the tire, the more direct the friction on the ground, and the grip is easier to output from the inside to the outside, making the tire more stable; 3. Beautiful appearance, many luxury cars will use large wheel tires, which are stylish, luxurious and face-saving; 4. Disadvantages, poor shock absorption, the larger the hub, the smaller the relative tire, the smaller the tire, then the tread of the tire will be thinner, and the gas in the tire will be less, so the buffer of the tire will be weaker, and the shock absorption effect of the tire will be poor; 5. High fuel consumption, the wheel hub is a metal product, because the metal mass is larger, so the wheel hub is heavier, and the large wheel means that the tire will be heavier, and the weight of the large wheel will consume more oil. The fuel consumption of large wheels will be relatively high.
