What are the pitfalls of buying wheels?? | JWHEEL

Many people modify the original intention of the hub is actually simple and rough: good look! Change Wheel HUB SAFETY FIRST!! Rather than choose a source of unknown "imitation",  as honestly choose a regular professional manufacturers to produce brand wheel hub. For safety reasons, JWHEEL's aluminum alloy wheel appearance and structural design are all based on the premise of meeting the requirements of safety and use functions. For ordinary passenger cars, our aluminum alloy wheels are sufficient to meet their performance requirements.

What are the pitfalls of buying wheels? Let's discuss this topic today.


     

 Misunderstanding 1: the lighter the better?

Modified industry legend: the spring 1 kg is equal to the spring 10 kg has long been popular, so many wheel modified users in the purchase of wheels, the hub weight as the first evaluation standard, excessive pursuit of lightweight hub.

Because the wheel hub is a safety part, the regular manufacturers of wheels are required to pass the strict hub three performance tests:

1) Impact test





2) Bending fatigue test





3) Radial fatigue test



                    


Visible, if the hub does not point "weight" is difficult to pass the three performance tests. On the basis of meeting the strength to reduce the weight of the hub is king!

At present, the performance test standards of wheel hub mainly include:

1) Japanese JWL VIA standard

2) German TUV standard

3) American SAE Standard

German TUV standards are the most stringent, which is why European wheel brands are heavy. The following European BBS 19X8.5J cast wheel hub weighs 11.65KG, compared with other cheap cast wheel 19X8.5J hub weight is 10.68kg.



   


Attached is the hub weight reference table, if you buy a particularly light hub , pay attention.

Change HUB SAFETY FIRST!!





Mistake 2: the larger the size of the wheel, the better.


Many people modify the original intention of the hub is actually simple and rough: good look!

The wheel size is larger, the vehicle effect looks bigger, more powerful. To be frank, it's even higher! But blindly increase the size of the wheel hub,calipers, baffle, suspension system is easy to hit, even lead to heavy damage the vehicle suspension system and increase fuel consumption.

General conventional wheel hub modification or upgrade to a maximum of 2 inches is appropriate, but also pay attention to the collocation of tire specifications, tire diameter change <3%. Otherwise it will affect the accuracy of the code table, even may receive a lot of tickets for no reason.





Mistake 3: take the wheel by "appearance", ignore the hub parameters.

The change of wheel hub style has an immediate effect on the appearance of the vehicle. But if only pay attention to the hub appearance did not pay attention to the hub parameters to match the original car data, it is easy to replace the hub and wing plate, calipers, shock scratch and even can not be loaded.

The following important parameters of the wheel hub are related to the loading of the wheel hub, which needs special attention:

1) Hole spacing (PCD) : must be exactly the same with the original car data.

2) Offset: If the offset is not appropriate, the hub is easy to interfere with the shock absorber or wing plate.

3) Center hole (CB/HUB) : If the center hole of the hub is small, it cannot be loaded at all.

4) Size (Size) : the size of the modified hub should match the model. Too big or too small will have loading problems.






Misunderstanding 4: covet cheap price

With some "explosive" hub popular, the market above a lot of similar products under the guise of the so-called genuine OEM or Taiwan production, and the price is very "close to the people". But these unknown origin of the wheel hub, there may be great safety risks.

Please find regular manufacturers and buy wheels that are produced according to quality standards. Jwheel are alloy wheel manufacturer with 30 years’ experience. We are cooperating with many brands in the world. We can produce alloy wheels according to the JWL VIA TUV SAE Standard.

Change Wheel HUB SAFETY FIRST!! Rather than choose a source of unknown "imitation",  as honestly choose a regular professional manufacturers to produce brand wheel hub.





Misunderstanding five: do not use the center ring (diameter ring) hub is a good hub

The center ring is called Hub-ring. there are mainly ABS and aluminum alloy. Here is a popular science about the origin and role of the center ring (reducer ring) :

1) Why use the central sheath ring (reducer ring)?

Due to the same hole distance (PCD) of different models of the center hole data is not the same, in order to save inventory, the majority of modified hub manufacturers will make the hub center hole data larger, to meet the needs of different models. When the hub center hole is larger than the shaft head, there will be a gap between the shaft head and the hub center hole. At this time, it is necessary to fill the gap between the center ring, to help the hub and the vehicle axle head closely.

The hub of the original OEM factory is produced for the model, and the center hole data of the hub is exactly the same as that of the model. So you don't need a center ring.



2) The function of the central sheath ring (reducer ring)?

When the hub is installed, the center sleeve ring mainly plays a role of positioning and fixing the hub. Make the hub center coincide with the shaft head center. It should be noted that the central sheath does not play the role of bearing.

Such as the hub center hole is larger than the vehicle axle head, without the use of the center ring, the vehicle is prone to jitter when driving at high speed. It can be seen that the center ring is a very common and important part of the refitted hub.

Some businesses on the market do not need to promote the center of the modified hub of the ring, personally think that marketing gimmicks are greater than the actual effect. For hubs that require the use of a center ring, just use the appropriate size of the center ring. No problem at all in daily driving!




  

Mistake 6: ignore the hub installation step, the hub is not properly installed

Many friends to change the wheel hub, wheel hub online shopping with very excited mood must not immediately drive to the store installation, expecting the wheels finally arrived and then install immediately without any inspection.

Due to the current modification of the shops, the original thought that the hub installation of So easy if you do not pay attention to the following installation details, or out of the control:

1) No diameter reducer is installed: the vehicle may have jitters problem during daily running.

2) Dynamic balance weight does not return to zero: when the vehicle is running at high speed, it may shake.

3) No torque plate is used to tighten the hub manually: too loose the hub may be in danger of falling off, too tight may damage the nut/bolt.

4) Tire specifications do not match the hub: tire wear is abnormal, and even the hub can not be installed or there is a rub problem.


Jwheel, as an professional wheel manufacturer, concentrates in R&D and manufacturing of aluminum alloy wheels, including casting wheels, forging wheels and flow-form wheels. The products of it have passed the certifications of SEI、SEMA,VIA, JWL, JWL-T, TUV and so on. Since establishment, Jwheel has been developing steadily, with rich experience of designing and producing aluminum alloy wheels. It has earned the appreciation of both domestic market and foreign market with its high technology, good quality and customer service.
