The size of the car wheel rim will have different effects on the carrying capacity of the car, the performance of cornering, etc.The specific use of large and small wheels, the owner can choose according to the difference between the two. 1. In terms of carrying capacity, large wheels are stronger than small wheels.In order to save costs, small wheels usually choose steel materials, while large wheels choose to use aluminum alloy in materials, especially the forging process is better, and the carrying capacity is 5 times that of ordinary steel wheels. 2. The performance of cornering.When the wheels are cornering, large wheels can improve the cornering performance of the vehicle.After the wheel rim is modified, the grounding area of the tire is increased, which can increase the grip, so that the vehicle's smooth cornering performance is improved, which is conducive to the safe cornering of the car.The small wheels do not perform as well as the large wheels in terms of cornering performance. 3. In terms of comfort.The larger the tire, the thinner the thickness of the tire, resulting in poor noise on the isolated road, then there will be more noise in the car.Small tires, to a certain extent, can reduce noise and make driving comfort higher than large tires. 4. Car performance.Because of its large size, large wheels will affect the acceleration and braking of the car.The larger the tire, the more its weight will increase, and the car needs to consume more fuel to be able to support the operation of the large tire.Because of its relatively small size, small wheels will use less fuel than large wheels in terms of fuel consumption, which can also accelerate faster than large wheels.

If the wheels of our cars are rusty, the following methods can be used to solve it.： 1. You can use very fine water sandpaper dipped in water and gently rub it on the rusty place to remove the rust spots and then apply a layer of primer, so as to ensure that the rust spots will not expand. If it is a relatively new scratch, apply the primer directly after wiping, the effect is better. 2. The above method is to directly polish and then spray primer for relatively small rust marks. Although it can solve the problem on the surface, it cannot solve the problem fundamentally, because the primer may fall off after a period of time. In fact, the most correct method is to polish and paint the wheel rim when it is scratched but not yet rusty, so that there will be no rust and corrosion. 3. We need to rinse the edges of the tires of the car with water first, especially the dirt inside. The second is to spray the rust remover evenly on the rust remover in an appropriate amount. After waiting for a period of time, use a sponge to wipe the surface repeatedly, and the rust on the wheels will disappear. 4. You can choose to put oxalic acid on top of the rust, then drop a few drops of warm water, wipe it gently, and then wash it off with water. This operation must be done quickly to avoid corrosion. Lemonade can also achieve the same effect, but it will leave a light yellow color that is more difficult to remove. Under normal circumstances, our aluminum alloy wheels are not easy to rust, but if they are made of steel or iron, they will rust more easily. It is better to choose aluminum alloy.

In life, tires are a very important part of the operation of the car, so where do you need to repair them when there is a problem or damage to the wheel rim of the tire?In fact, this is relatively simple. Usually, you can go to a special repair shop or the 4s shop of the car for a comprehensive overhaul. Before performing repairs, a comprehensive inspection must be carried out to clarify where the problem occurred, so that not only can the repair time be saved, but the repair will also be more perfect.Some wheels have a little damage and scratches on the surface, but other problems are not big. This kind of problem is the simplest to deal with. Only a simple surface repair and a comprehensive spray of paint are required. However, if it is because the car has experienced a more serious collision or other scratches, causing it to deform, etc., it needs to be restored first and then the next step of painting and other treatment, so as to better restore the wheel as a whole.Finally, when it is in severe deformation and there will be serious damage, it needs to be completely replaced. In summary, we can summarize that the specific repair work of the wheel rim is relatively simple, that is, a simple and comprehensive cleaning work is carried out along the route to further clarify the degree of damage, and then carry out detailed further treatment.In particular, it is necessary to remind the majority of drivers and friends that the inspection and cleaning of tires and wheels must be carried out frequently in life, so as to be more conducive to driving and safety.

The rim et value means the offset value, which represents the deviation distance between the rim mounting surface and the center line of the rim. The wheel rim et value can be divided into positive and negative offset distance and zero offset distance. When the wheel rim et value is larger in the positive direction, it means that therim mounting surface is inward. The distance indicates that the mounting surface is in the middle of the rim. Does the larger the et value, the more prominent the wheel rim? This is not the case. The larger the et value of the car rim, the more inward its mounting surface is, so it does not protrude outward, but indents inward. Generally, those four-wheel drive vehicles will use wheels with a negative et value, in order to increase the wheel spacing to make the vehicle more stable, and to make the best use of their high-performance tires. Our ordinary vehicles generally use wheels with positive et values, because ordinary vehicles do not pursue the ultimate driving performance, and generally prefer safety. How to choose the et value of the car rim? When choosing a car wheel, you should consider the configuration of your own vehicle, and you cannot choose a new wheel that is too different from the original wheel size. If the selected wheel rim et value is not suitable for the own vehicle, it will lead to the deviation of the driving direction of the vehicle, or the work of the braking system will be affected, and increasing the braking distance will affect the driving safety. In addition, you can judge according to your own model. If it is a four-wheel drive vehicle, you can choose a wheel with a negative et value to increase the driving performance. If it is a general two-wheel drive, choose a wheel with a positive et value.

1. Select a suitable cleaning agent. Household cleaners and common detergents on the market are more alkaline or acidic and more corrosive to the wheel surface. To avoid contact with strong chemicals, choose neutral soapy water to wash your wheels. 2. Do not wash the wheels when the temperature is too high. When the temperature of the wheel rim is high, please do not directly wash it with cold water. Please wait until cool before washing. Otherwise, the alloy wheels will be damaged and the brake disc may be deformed. affect the braking effect. In addition, washing the aluminum alloy wheel with washing powder at high temperature will cause a chemical reaction on the surface of the wheel, lose its luster, and affect the appearance of the wheel. When cleaning aluminum wheels, use a sponge or towel. Please don't use too hard wool brush. Using a steel wool to remove stubborn stains can damage the surface of the wheel. 3. Clean the rim properly. If there are hard-to-remove stains on the surface of the wheel rim, a professional cleaner should be used to remove the stains gently and effectively to reduce the damage to the surface of the aluminum alloy. When the car has been used for a certain period of time, when a hard, dark brown coke layer forms on the wheels, a cleaner is needed. If the rim is soiled with hard-to-remove tar that general cleaners won't do, use a brush to remove it. However, please do not use too hard brushes, especially iron brushes. It is easy to damage therim surface. The car is in a wet or near coast. To prevent the aluminum surface from being corroded by salt, the wheels need to be washed frequently. After washing as needed, apply wax to the rim to keep it shiny. 4. Develop good driving habits. Car owners should pay attention to lower road obstacles in daily driving, and do not park too close to the roadbed. In this way, the rim is easily damaged, and the appearance and rust of therim are also prone to occur. Removal of waterproof coatings that affect waterproofing and corrosion resistance. This will deform therim and affect driving safety.

1. Heat dissipation requirements: If the car runs for a long time, it will make the car wheel very hot. What’s more, the braking system will also generate a lot of heat. If this heat is not released in time, it will bring a big problem to the driving safety of the car and may cause the tire to burst. The hollow design can increase the contact area between therim spokes and the air, which is conducive to heat dissipation. 2. Reduce the weight of the car rim: As we all know, the lighter the mass under the spring, the better the car performance, the higher the acceleration and braking, and the higher the fuel efficiency. The hollow design greatly reduces the weight of the rim, and the aluminum alloy also provides enough strength for the spokes to support the rim. 3. Material saving: The hollow design saves the aluminum alloy material used in the manufacture of the wheel rim, reduces the production cost of the automobile wheel rim manufacturer , and also reduces the purchase price of the consumer. 4. More beautiful: At present, car manufacturers are paying more and more attention to the design of the wheel rim. A good car wheel design can improve the integrity of the car's design and play a finishing touch. Hollowed spokes can be made in various shapes to meet the needs of different consumers.

An alloy wheel is an automobile wheel that is made of alloys of aluminum or magnesium. Getting a good run via cars and motorcycles, this segment has seen a sudden spurt in demand in the recent years. As magnesium was used earlier for making an alloy wheel, these wheels were often termed as mag wheels (MAG for magnesium). As compared to traditional steel wheels, This type wheel has the advantage of lightness. As in, for the same strength as compared to a traditional wheel, these wheel will be considerably lighter. In addition, these wheels come with an aesthetically attractive appearance and even provide better heat conduction. Lighter wheels can improve the overall performance in a variety of ways. As it will directly contribute towards reduction in the overall mass of the vehicle, the fuel consumption will definitely reduce. It also affects the suspension part and better heat conduction helps to disperse heat from the braking system; this manages to improve the braking performance, more so in demanding driving conditions where brake failure because of over heating can occur. alloy wheels also carry a problem of electrochemical or galvanic corrosion and in due course of the time, the tyres could leak air (if there are no preventive measures taken). Also, unlike the traditional steel wheels, it is kind of difficult to repair wheels in the event of bends or other damages. Now coming to the commercial aspects, this type of wheels do cost more than its steel counterparts. It is this commercial aspect that doesn't allow some automobile manufacturers to provide alloy wheels as standard equipment (mostly pitched in as add-ons for a better price). Some manufacturers offer a latest addition called as the - locking wheel nuts. Special keys are required to remove the wheels fitted with these nuts, and in a way it counters the problem of these wheels getting burgled (mostly the case with expensive sports editions which are fit with expensive wheels). Unlike what is perceived, not only cars and motorcycles, even trucks get fitted with these as the small advantages like better braking and better heat conduction get magnified in the running of heavy vehicles. Processes Used for Manufacture of Alloy Wheels It is actually the rim and the wheel. Most alloy wheel rims are manufactured via a combination of aluminum, carbon and some other alloys. In terms of modes used to manufacture the wheels, there are 2 processes which are used; first being the casting method and the second is the forging method. In terms of casting, 3 methods can be used which are as follows · Low pressure die casting · High pressure die casting · Permanent mold and sand casting ( gravity casting )

1. Durable and safer Forged aluminum rings are 1-2 times stronger than cast aluminum rings and 4-5 times stronger than general iron rings, so they are stronger, have better toughness and fatigue resistance, and are safer. 2. Lightweight Forged wheels of the same size can be about 20% lighter in weight, and 1KG lighter on the wheel can increase 10 horsepower. In addition, the lightweight also significantly improves the response speed of the suspension, making it easier to deal with road potholes. Bump is greatly reduced 3. Fuel saving and good heat dissipation performance According to Japanese experiments, the weight of a 5-seater car is reduced by 1kg, which saves about 20L of gasoline a year. Forged wheels have better heat dissipation, high-speed driving, and tires are not easy to bulge and blow out. 4. Better handling performance Upgrading the forged wheels increases the width of the wheel without affecting the steering and loading, so that the acceleration, braking and sensitivity of the vehicle are significantly improved, and the car will obviously feel light underfoot. 5. More beautiful Because the forged wheel hub has a compact structure and can withstand high stress, it can design some relatively lively thin spokes in the shape design, and the design freedom is also high. Cars are more personalized.

Many people think that as long as the wheel hub is bigger, it must be better, after all, it is certain to look good. But there are often disadvantages. The disadvantages will be discussed in a while, let’s talk about how to choose the hub and what craft to choose. At present, there are three mainstream process hubs on the market, low pressure casting, flow forming wheel and forged wheel. This is most of the crafts on the market at present, and it is not ruled out that there are small workshops and gravity wheels. Let's talk about the differences and craftsmanship of these types of wheels. Low pressure casting wheels Low pressure casting is well understood. It is to set the mold, and then pour the molten aluminum into the mold, and then apply a certain pressure to make the internal molecules more compact. This is low pressure casting. is to use this wheel. Because of the high cost performance and good production, the price is also cheap and affordable. Flow forming wheels Spinning is actually more complicated processes on low-pressure casting, and they are all produced by low-pressure casting, but the part of the rim is heated and rotated and stamped by a spinning machine, so that the molecular density of the rim part can be improved. Corresponding rims are more rigid, so many car owners have chosen spinning wheels. Of course, it should be too expensive for forging. Spinning takes an intermediate value between casting and forging, which has both cost-effectiveness and performance. The current price of spinning wheels Also somewhere in between. Likewise, the spun hubs are made of the same A356 casting aluminum as the low pressure cast. Forged Wheels The forged wheel is different from the aluminum used in the above two. It uses 6061 forged aluminum. The rigidity is like the difference between the iPhone 6 and the iPhone 6S in previous years. One is bent. The forged wheel not only occupies the aluminum and rigidity Advantages and weight are also the reasons why many people choose. Lightweight means lower fuel consumption and better control of the body. The most important thing is that forging supports customization. You can do whatever you like. The engineer draws the drawings according to the requirements, and then mills them on the forged aluminum blank. The first two are not supported. After all, no manufacturer will reopen the mold. This is why forging is expensive. Nanjing Diamond Hope Machinery Trading Co,.Ltd. was established in 2009,the main products are forged wheel rims,aluminum lug nuts and wheel adapters.Support OEM/ODM/custom services.

In many unexpected times, there will be unexpected situations in the finishedrim, which will make the finished defective. At this time, we need to repair the wheels. Most of the wheels on the market are electroplated, so the maintenance of thechromed wheels and the precautions for the maintenance of the wheels are easy to share for you. When repairing arim, the first thing to do is to determine whether it is anchromedrim. If not, repairs in the electroplating plant are meaningless. If there is no plating, it should be painted. Chromed wheels can also be divided into silver plating, water plating and pure plating. Among them, pure chromed wheels have a long service life and good quality. Most middle and high-end automobiles use pure chromed wheels. When repairing or upgrading, we should pay attention to the following points: Rim deviation, PCD value and hole position, and the size and shape of therim are basically the places that cause problems, so you should pay attention.

Once you have made a wheel sale, test-fitted the wheels, and mounted and balanced the tires, you must do one final thing--attach the wheels to the car. Although often overlooked, the hardware associated with wheels is vital to getting a good installation. The most obvious piece of hardware is the lug nuts used to secure the wheel to the car. In most cases, either for appearance sake or functionality, you won't use the stock lug nuts to attach the wheels. Lug nuts come in three broad categories: acorn, mag and tuner style. Within each category, there are a number of variations. Some European cars use a fourth type--a lug bolt which screws into the vehicle. A typical catalog shows nine acorn styles, three mag styles and five tuner styles. Fortunately, the wheel catalog will usually tell you which type of lug nuts to use with the wheel you are buying and of the 17 styles mentioned above, a few are pretty rare. It's a good idea to have the more common styles in stock to prevent any delays when installing wheels. Acorn styles are the most common and they are available in either open end design, which are used when the lug nuts are covered by the wheel's center cap, or closed end type, which are used when the lug nuts are exposed. Closed end designs come in various lengths, the longer ones normally used on trucks where extra length is needed. Mag styles are the least common, used mainly on older style wheels. Mag lug nuts must be used with washers. Tuner style lug nuts are used where there is very little room in the lug nut opening. This is especially common on small, front wheel drive cars known as "tuners." That's where the name comes from. They come with a "key," which either fits into a cut out in the center of the lug nut or goes over the lug nut itself. Without the key, you can't remove the lug nut, so make sure you give this to your customer.

When shopping for nuts make sure they match the thread diameter, pitch and seat of the ones you are replacing. If these aren't the right fit, the new nut may hurt your expensive wheels. They can also ruin the mounting lugs for your vehicle, which is not a cheap proposition. And then there's the fact that improperly secured wheels make your car a potential hazard on the road. The three basic types of nuts are: conical seat (60 degrees taper "acorn" and "bulge"), mag or shank style, and spherical or ball seat. Thread diameter refers to the diameter of the stud measured across the shank at the outer edges of the threads. Thread-pitch means either the number of threads per inch or if metric, the distance in millimeters between threads. The seat means the area on the wheel where the nut will clamp down. Manufacturers only recommend one wheel lock lug nut per wheel to keep your wheels from being stolen. The wheel lock lug nuts come with a special tool that you attach to your wrench so that only you can unlock your wheels. Custom lug nuts can have special chrome plating so they are resistant to rust and normal wear and tear. This kind of nut also comes in different color caps so that they match the color of your custom wheels. After all, if you've invested in both custom wheels and nuts, you want them to look good together. This very small investment can add value and protection to your wheels. It seems like a logical choice when you are going to the trouble to upgrade this part of your vehicle.
