Chinese people have always liked big things, such as buying big phones, buying big houses, and so on. Taking buying a car as an example, not only does it require large space, a large sunroof, a large appearance, and a large wheel hub. Of course, large spaces and skylights can bring us a better driving experience, but does the wheel hub have to be as large as possible? Let's take a look together. As we all know, wheels are composed of two parts: tires and wheels. Different car models are equipped with different types of wheels and tire models. For example, the tires of off-road vehicles are thicker than usual, but the contour is not too large. On the other hand, sports cars are generally made of tires, with thinner sidewall ratios and very large wheels. Our ordinary family sedan wheels are generally not very large, and the sidewalls are also relatively thick. However, different configurations of the same car can also have different sizes of wheel hubs to choose from. What is the difference between these? Is the wheel hub larger, the tire wall thinner, or is the wheel hub smaller, the tire wall thicker? We first need to understand the specifications of the wheel hub size. At present, tire size is a unified standard internationally, and there are generally the following six data, Tire width, tire flatness ratio, tire type code, hub diameter, load index, and rated vehicle speed. For example, for 225/55/R16 tires, 225 refers to the width of the tire cross-section, 55 refers to the tire flatness ratio, and 16 refers to the hub diameter. For the same vehicle model, the tire's exterior must not change significantly, otherwise the speedometer on the dashboard may be inaccurate. Therefore, if you want to replace a large wheel hub, Then you should choose flat and relatively small tires. For example, if the original factory had a 16 inch wheel hub with tire sizes 225/50/R16 and wanted to upgrade to a 17 inch wheel hub, the tire model should be 225/45R17, with a flat ratio reduced from 50 to 45. Even so, the two cannot be exactly the same in terms of outer diameter, with a tolerance of 3%. So, the wheel hub size of the same model is not fixed, and many brands also adjust the wheel hub size to distinguish configurations. So, is the larger the wheel hub, the better? Actually, it's not necessarily that big wheels have the advantage of big wheels, and small wheels also have the advantage of small wheels. Let's take a look together. Advantages of large wheel hubs
1. It has a very good visual impact, and the combination of large wheels on the body is more plump. It can also present more styles in the design of wheel rims, highlighting the visual effect. 2. It can improve handling. Under the same specified tire outer diameter, the larger the wheel hub, the lower the flatness ratio, making the tire wall thinner and providing clearer feedback on road conditions; When turning at high speeds, wider tires are less likely to deform, giving them a larger touchdown area and stronger grip. 3. The modification space is larger, and a large wheel hub means that the internal space of the wheel hub is also larger, which can accommodate larger brake discs and calipers, improving the braking effect of the vehicle. Advantages of a small wheel hub: 1. It has high comfort. With the same tire outer diameter, the smaller the tire wall, the smaller the wheel hub, which means that the tire has better shock absorption ability and can filter out some small bumps on the road. 2. The cost is lower, and the materials used for small wheels are less than those for large wheels, so the cost is lower, and the corresponding small-sized tires are also much cheaper. 3. The fuel consumption is lower, as the weight of small wheels is much lighter than that of large wheels, and the rolling resistance is also lower, so the fuel consumption is also lower than that of large wheels. The above are the advantages and disadvantages of the two. Comparing them, each has its own advantages and disadvantages. If you focus on visual effects and handling, the large wheel hub is stronger than the small wheel hub. If it comes to comfort and economy, the small wheel hub has some advantages.
