Method 1 of automobile hub modification: make clear the purpose. Before refitting automobile wheels, it is best to think clearly about the purpose of refitting and avoid blind choice. Know whether you want to get better control performance or improve the visual effect. Because there are many different types of wheels like cars, the effects and functions of different types of wheels installed on cars are different. Generally, the structure of competitive wheels is relatively simple, aiming at lightweight. If it is beautiful, you can also choose two-piece or three-piece forged hub.

The second modification method of automobile hub: the size of hub offset can not be ignored. After figuring out what size wheel hub and corresponding tire should be selected, you can move on to the next step. There is still a lot of information worthy of our attention in this step. First of all, the most basic ones are hole position and hole spacing. The hole position refers to the number of locking nuts when the hub is fixed. At present, most cars are designed with five holes, and a few models still use four holes, such as Jetta and Gower, and some off-road vehicles use six holes. Judging from the number and style of products on the market, the choice of 5-hole hub is relatively large. As for the hole spacing and hole diameter, this information can be obtained from the manual, or simply given to the store for field measurement. It should be noted that the hub with improper aperture may be installed smoothly, but there will be certain safety hazards (wheels may shake when driving at high speed), which should be avoided as much as possible.

Modification method 3 of automobile hub: tire hub is inseparable. When many people buy new wheels, they usually choose bigger wheels than the original products. The first thing to note is that tires and wheels are inseparable parts. In the modification process, it is very necessary to keep the tire extension diameter unchanged or control the change as small as possible. One of the main reasons is that if the deviation is too large, the accuracy of the instrument will be problematic. It is not feasible to enlarge the hub without replacing the tire. For example, the tire size of the original car was 215/60r 16 (16 means16 inch wheel hub), so if it is replaced with 17 inch wheel hub, the new tire size is preferably 225/55R 17. We noticed that with the increase of the wheel hub size, the width and flatness of the tire also changed, so what is the relationship here? In principle, the diameter change value should be controlled within 3% of the original specification.
