If you want to modify the wheel hub, you'd better find a professional wheel hub factory. They will have all kinds of wheels for you to choose from. You can choose painting or electroplating, wide spokes or thin spokes according to your personal preference, and some people will suggest what kind of wheel hub you'd better change, because it is related to a matching problem after installation, such as the central hole and bolt hole, which must be the same as the original factory. Another important thing is whether the brake caliper will interfere with the spokes. Hub upgrade diameter shall not exceed 2 inches and width shall not exceed 1.5 inches. That is to say, for example, if your original wheel hub is 15*6.0, then the ideal size after upgrading is 17x7.5, and then you can get a better grip on driving performance by replacing it with a corresponding flat tire. No matter how big the size is, there may be group steering interference and fender collision. At present, the wheels supplied by the hub factory are relatively cheap and the quality is guaranteed. Larger wheel hub factories are supporting foreign automobile manufacturers. Some 4S stores have few kinds and poor quality. I once saw the wheel of Chang 'an Star in Chang 'an 4S shop, which was a piece of garbage.
