Big wheels look good, but why shouldn t you blindly replace them?

The tires of many family cars are generally relatively small, not to mention whether they can be installed without damage, first of all, you must know the disadvantages of changing the large wheel, first of all, the speedometer and odometer will be inaccurate, because the speed of the gearbox output shaft when the car is measured to determine the number of turns of the tire rolling to determine the speed, the tire increases the circumference and becomes longer, and the speed will change accordingly.

Because some cars are not suitable for large wheels at all, there may be a certain danger after replacing them, so when replacing large wheels, you must determine whether it is suitable.

The wheel hub is changed to be larger and has the following main impacts on the car: 1. The wheel hub is larger, and the outer diameter is basically unchanged, but the tire with a lower flat ratio must be used, the tire grip is better, the handling becomes stronger, but the comfort is reduced, the rolling resistance of the tire is greater, and the fuel consumption will be increased accordingly. Bi Han socks, 2, affect the annual inspection, the annual inspection must ensure the state of the vehicle when leaving the factory, the wheel hub and tires are modified to be larger, generally more strict places are difficult to pass the annual inspection, must be changed back.

3. The replacement of the wheel hub is not suitable, affecting the safety, the center hole of the hub is very important, that is, the big hole in the middle of the hub, if the axle hole of the rim is large, you must use the middle hole collar, otherwise the wheel will shake when the brother is at high speed, as well as PCD, offset, etc., if the offset is too large after replacement, it will rub with the body.

The wheel hub cannot be re-dimensioned. Here are the specific instructions about the wheels:1Definition: The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire steel by the column, that is, the metal part that supports the center of the tire mounted on the axle. Also known as the rim.

Rims, wheels, tire bells. There are many types of hubs according to diameter, width, molding method, and material. 2.

Wheel hub development: In the past, the wheel bearings of passenger cars used to use single-row car ridge tapered rollers or ball bearings in pairs. With the development of technology, sedans have widely used sedan wheel hub units.

3.Wheel type: Wheel hub is also called rim.

According to the characteristics and needs of different models, the surface treatment of the wheel hub.

The process will also take different ways, which can be roughly divided into two types: baking paint and electroplating.

The modification of the wheel hub belongs to the more conspicuous modification, and you can directly judge whether a car has been modified from the visual sense. If you must replace the wheels, you need to get approval from the traffic management department. In order to achieve the closest value to the outer diameter of the original tire, it is necessary to replace the wheel with a lower aspect ratio.

The direct result of the low aspect ratio is that the road feeling will be richer, which can increase the driving experience to a certain extent.

The hub is the part where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel rim". The wheel hub is easy to get dirty, and if it is not cleaned for a long time, it may be corroded and deformed, resulting in potential safety hazards.

Therefore, special attention should be paid to the maintenance of the wheel.

Because in order to pursue a better sense of handling and a stronger sense of the road, many car owners will replace the original wheel hub as soon as possible. However, it is easy to choose a fake wheel due to price problems when replacing it, so let's talk about how to distinguish between real and fake wheels:

Method. First, look at the appearance. Because of the false wheel hub or high imitation wheel hub in the production process due to the low precision of the mold, all the corners may have burrs, which is fake at first glance.

Method. 2. Weighing. The weight of the original wheel hub is basically the same, and the false wheel hub will be different from the original wheel due to the lack of its own production process and cost problems.

Method. Third, look at the brand and look at the origin. On the back of the wheel, there is generally information such as the brand and origin of the wheel. Although the information is the same, the font of the original wheel is difficult to imitate, just compare it.

Method. Fourth, with the original wheel hub for detailed comparison.

The types of wheels are usually distinguished by materials, which can be divided into three categories: steel wheels, aluminum alloy wheels and magnesium alloy wheels, all of which have their own advantages and disadvantages in the manufacturing and use process: the main advantages of steel wheels are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue, but the disadvantages are also obvious, such as large weight, large inertia resistance, poor heat dissipation, etc.; The advantages of alloy wheels are light weight, high manufacturing precision, high strength, low inertia resistance, strong heat dissipation ability, good visual effect, etc., and the disadvantages are complex manufacturing process and high cost.

Regardless of the material, the wheel hub is made up of seven parts, namely the rim: the wheel part that fits with the tire assembly and supports the tire; Spokes: the wheel part that implements installation connection with the axle hub and supports the rim; Offset:

the distance between the center surface of the rim and the mounting surface of the spoke; Rim: The part of the rim that holds and supports the direction of the tire; Bead seat: In contact with the tire rim, it supports the rim part that maintains the radius direction of the tire; Bottom of the trough:

In order to facilitate the assembly and disassembly of tires, leave a pit with a certain depth and width on the rim; Valve hole: The hole through which the tire valve is installed.

For safer**, it is advisable to choose a store with a relatively large brand and not to choose a product that is too cheap. Because the wheel hub really greatly affects driving safety.

Despise the landlord, people like to change how they want, and it's not your money, people like to be beautiful, to change the vest out of the scolding, despise such garbage,

In fact, the modification to improve the performance is mainly concentrated in 3 point 1, aerodynamic system 2, tire brake suspension system 3, power system if you have money to change a little more, if the money is less, you can add a rear wing, as long as you change the same can get some performance improvements. Of course, the various systems of the original car are well adjusted, but pay attention to balance and comfort, so if you want to get a relatively large improvement in a certain performance when modifying, you will definitely sacrifice some other performance. There are also simple and hardcover modifications, and the luxury fine decoration is bottomless, but a house is only covered with a plastic carpet, which is also considered decoration, after all, it is cleaner than the cement floor, although it will exude the smell of plastic.

So changing the wheels is of course a modification, and it does improve some performance. As for sticking a few fancy stickers on the body and installing a few messy lights, that's not actually a modification!

The upstairs tells you that the brake disc should be changed to a large steel rim, otherwise the original steel rim will not be installed. There are a lot of so-called modified cars on the road that do not increase the brake discs in order to look good, and the brake discs have been replaced with large wheels, which do not play a practical role. It's funny. Hahaha!

There is no outstanding benefit to replacing large wheels in the car, modifying the wheels, violating the traffic law, is an illegal act, and it is fined according to law and ordered to be restored to the original state.

In case of a traffic accident, the insurance claim is to repair the wheel hub of the original car, if it is repaired to the modified appearance, the cost is at your own expense.

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.

Unauthorized modification of the chassis, engine, suspension, transmission system, steering system, tires and wheels, lights, body color spraying and appearance structure, as well as the relevant technical data of the motor vehicle and the data announced by the competent department of motor vehicle products are all modifications.

The advantage is that it is beautiful, and then the wider tire car will be more stable in the process of driving and turning, and the disadvantage is that the indication of the odometer has been changed, and the actual speed is fast according to the meter.

Replacing the hubs requires changes to the brake discs, odometer, boosting engine power, etc.

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.

Hope it helps! Practitioners from Zhanjiang Jinfu Automobile!

The advantage is that it is beautiful, and the car with wider tires will be more stable during driving and cornering.

The downside is, 1Changed the indication of the odometer, and the actual speed is faster as on the meter.

2.The increased load on the steering machine will be the early retirement of the steering machine.

3.The load on the engine is increased, especially when starting to feel "meat".

4.The body is raised, and the ground clearance side is large, which will cause the original aerodynamic change at high speed, and cause the car to drift.

5.Increasing the load on the braking system will put your brake pads and brake pads into a replacement period early.

6.Directly affect your fuel consumption, that is, fuel consumption, common sense is 10 liters of fuel consumption will increase half of the oil If it is a city transportation tool, for the sake of beauty and hobbies, it is recommended to replace it, because it is really beautiful.

If it is a bus or the usage rate is relatively high, it is recommended not to change it, the less you run, the less the loss, the greater the loss of running every day, and there is no need to pay all the expenses in advance. Please think carefully!

The impact of the wheel hub on the car is as follows: 1. Fuel consumption will increase, because the contact area between the tire and the ground is larger, the greater the friction between the car and the ground, the greater the energy loss generated by friction, and then all the power of the car is to burn oil, the more energy is lost, the more oil to be burned, and the greater the fuel consumption; 2. It will cause the odometer to be inconsistent with the actual mileage, the tire size becomes larger and the circumference becomes longer, and now the tire turns a circle, which is equivalent to turning a tan car circle before, and the process calculated by the schedule will be smaller than the previous one; 3. It has a great impact on the control of the car, and the change of large wheels and tires will have an impact on the control, first of all, the amount of heavy sails, if the material of the larger tire rim remains the same, then it will be heavier than the original.

The main reason for car owners to modify large wheels is because car owners want to improve the handling performance of the vehicle, so changing a set of large wheels and high-performance tires will be a considerable help. Large-sized wheels are modified not only to look good, but also to provide stronger driving force, but also to reduce fuel consumption.

If the owner is only for ordinary household use, then the change of large-size wheels does not make any sense, and for a family car that pursues comfort, modifying large wheels will only affect comfort.

The wheel hub of the vehicle is not allowed to be changed casually, even if the tire seems to have a simple structure, but the size of the tire changes, the original data on the car will change accordingly, after all, only the tire and the road surface contact; The most obvious impact of replacing the wheels is the mileage, which will become smaller than the normal driving data, thus disrupting the judgment of the maintenance cycle originally recorded by the vehicle, so it is not recommended to replace the wheels casually.

It should be noted that after changing the size of the wheel, it is not possible to pass the annual inspection and vehicle transfer, and only the official record of changing the driver's license can pass the annual inspection.

In order to achieve the value closest to the original tire diameter, the tire with a lower flatness rate needs to be replaced. As a direct result of the low aspect ratio, the road feeling will be richer, which can increase the driving feeling to a certain extent.

But on the contrary, the road feeling will be more bumpy, because the flattening rate is reduced, the tire wall will be thinner, the shock absorption and cushioning capacity will be reduced, the same tire wall is thinner, and if you don't slow down like the original tire when going through big bumps, usually the tire will bulge.

In the case of large wheels that do not change the wheel diameter, there is no doubt that thinner tires need to be replaced, thinner tires can improve the handling of the vehicle but will make the vehicle comfortable, some owners think that the bigger the wheel, in fact, the wider the tires, the better.

The owner must choose the right wheel diameter when choosing, although increasing the wheel diameter and wheel width can enhance the driving stability of the vehicle and improve the heat dissipation performance of the brake, but it is undeniable that the wheel assembly torque caused by the wheel diameter is too large, which will make the axle power rotate when the load increases, weaken the vehicle starting and acceleration power, increase fuel consumption, and even affect the handling of the slow steering wheel, shorten the service life of the steering wheel. Fitness makes a difference. At the same time, thinner tires are prone to bulging, and later maintenance costs will be higher.

The main reason is to make the car more powerful, but also to make the car safer and more comfortable to drive, so it will choose to modify.

The feeling of use is not particularly good, it does not look very good-looking, and there will be a very good feeling of use after replacement.

Improve the handling ability of the car, so it will be modified, and after the modification, you can better control the car.

The main reason is that large wheels can make the car more beautiful and make the owner more face-saving.
