How to make a car steering wheel cover?

   Many people want to make their cars look different, and the best thing to enhance their looks is the wheels.

   There are too many wheels to choose from on the market, various styles, various colors, and they are basically more handsome than the original wheels. In addition to improving appearance, what are the benefits of replacing them with better wheels?


  You should also find that many performance cars are reducing weight to improve performance.

   Indeed, adding ten horsepower is not as good as losing ten kilograms of weight. After weight loss, the car is more flexible and maneuverable when turning and changing lanes.


   At the same time, the shock absorber spring is ten kilograms lighter than the spring under one kilogram. One of the easiest and direct ways to reduce the quality of the unsprung is to change the wheel hub, which is like putting on a pair of light running shoes to run. It is lighter and less effortless.


  So what should I pay attention to when changing wheels?

   1. Regarding the choice of size


   Generally, the size of our household wheels is between 16 inches and 19 inches. We often say that the size of the wheel is in inches. The larger the size of the wheel, the better the visual effect.


   Next, the tires that match the wheels are the tires. When we choose large-size wheels, the aspect ratio of the tires we choose will basically change accordingly.

   When we choose a dfsk auto tire with a smaller flatness ratio, the more direct it conveys the sense of the road, the more conducive to handling. This is also the reason why many sports car tires look flat.


   But with low aspect ratio tires, the handling is improved, the comfort is reduced, and the vibration filtering effect is also reduced.


   Conversely, when we choose flat tires that are relatively flat, those that look thicker, the road feel will become less direct, but the better the vibration filtering effect, the better the comfort.


   If the wheel hub diameter is too large, the torque will increase and the load on the drive shaft will increase. With the same power, the power will be relatively weak when the car starts and accelerates.

   2, PCD value of hole distance:


   Here is a misunderstanding. The hole distance we usually talk about is not the distance between two adjacent holes. Most people will get confused here. The hole distance is actually a common name, and the professional name is PCD value.


   It is the diameter of the circle formed by the wheel hub mounting and dismounting screw hole.


Most people mistakenly think that the hole distance is the distance between two adjacent holes. This is a serious misunderstanding. This parameter directly determines what kind of wheel hubs you can change. Our family cars generally have 4 holes or 5 holes, while trucks and minibuses And large vehicles use 6 holes, 8 holes or more.

  3, the ET value of the wheel hub


   The ET value is the Off-set value, which refers to the deviation between the contact surface of the wheel hub and the center line of the rim, and the unit is mm. In other words, it is the distance between the joint surface of the rim and the center of the rim. The direction toward the outside is positive, and the direction toward the inner side is negative.


  4, the center hole of the wheel hub


  The center hole of the hub refers to the round hole in the center of the hub.


  We should also refer to this value when choosing a new CHANA CS35 wheel hub: for a wheel hub larger than this value, a collar must be added to be firmly installed on the car's bearing axle head, otherwise there will be shaking when driving. Then the hubs smaller than this value will naturally not be installed.

   5, the choice of wheel type


   In addition to paying attention to the above points when purchasing, we should also pay attention to the material and craftsmanship of the wheel hub. With different manufacturing processes, the performance and purpose of the wheel hub are very different.


   6, steel wheels


  The advantages of steel wheels are low cost, but also obvious disadvantages, poor heat dissipation, heavy weight, and also affect the flexibility of the CHANA CS55 vehicle, and the single style is also the reason why consumers do not like it. Steel wheels are configured in many low-end family cars. Many manufacturers also install a hub cover on the outside of the steel wheels for aesthetics to enhance the aesthetics. The materials are mostly made of plastic.


   7, aluminum alloy wheels


Family cars on the market, cheap high-end models and some models with more than 100,000 yuan generally use aluminum alloy wheels. The advantages are obvious. Compared with steel wheels, they are lighter in weight, better in heat dissipation, and have a more aesthetic design. , Each car brand also has its own iconic wheel design style.

   8, cast aluminum alloy wheels


  When choosing wheels of other brands, many of the wheels are more fashionable and dynamic in shape. Most of them are manufactured by casting, that is, the molten aluminum is poured into the wheel model.


   It is suitable for mass production of automobile manufacturers, and many wheel hubs bought by auto parts stores also use this process. In terms of strength, cast wheels are often not as rigid as forged wheels.


   9 Forged aluminum alloy wheels

Many high-end wheel brands use the forging process, which is made by high-pressure impact. Forged wheels have high rigidity while maintaining good light weight. Of course, the price is extremely expensive. Our common high-end cars and performance cars generally use forged aluminum Alloy wheels, in some road racing cars, the team will also use expensive forged aluminum wheels.


 How to remove the car wheel cover


  How to remove the car hub cover: first remove the screws on the edge of the hub cover, then grab the edge of the hub cover and pull it out to remove it.

   Inside the wheel hub is the drive shaft, which is tightly fixed by a large screw. In order to prevent the screw from moving, some cars will put a clip on the screw and put a cover on the outside. This The cover is the hub cover.


  The main function of the hub cover is to make people feel more beautiful, and it is not easy for water to enter the cover and corrode the screws, so that it can prevent rust and waterproof the big screws.


  In the daily use of tires, if the tire pressure is insufficient, it will increase the degree of tire deformation, and the tread patterns on both sides of the tread will also be excessively worn, causing the carcass to be unable to resist the pressure on the ground and deform, resulting in high temperature after friction. Accelerated tire wear, and eventually buried the hidden danger of puncture.

  If the tire pressure is too high, it will also cause the tire to lose its due elasticity and shock absorption ability due to the excessive hardness. Not only will the gripping ability be weakened, but the excessive wear of the central tread will also cause uneven tread depth. When the tires are running at high speeds, they may also burst due to the inability to withstand excessive inflation pressure.


  Therefore, if the air pressure of the tire is too high or too low, there is a risk of a puncture, so the air pressure problem should not be underestimated.


  All car owners should maintain the standard tire pressure, including the spare tire pressure, in accordance with the manufacturer’s requirements. The tire pressure can be measured with a tire pressure gauge by itself, but it must be measured at the normal temperature of the tire, otherwise the result of the measurement under the hot tire state will be inaccurate.
