How to replace Buick Excelle hub screws?

The replacement method of Buick Excelle hub screw is: 1. Lift the vehicle. 2. Remove the tire. 3. Remove the hub screw with a socket tool. The model of Buick Excelle high tire is 195/55R 15/85H, and the other models are 185/65R 14/86H. 16 inch and 17 inch wheels can be modified to increase the grounding area and improve the driving stability of the vehicle, but it will also increase fuel consumption. The difference between steel hub and alloy hub is as follows: 1. The advantages of steel wheel hub are simple manufacturing process, relatively low cost and strong metal fatigue resistance. 2. Steel wheel hub is bulky, with large inertia resistance, poor heat dissipation and easy to rust. 3. The alloy wheel hub is light in weight, low in inertia resistance, high in manufacturing accuracy and small in deformation, which is beneficial to improving the straight-line driving performance of the vehicle and reducing the rolling resistance and fuel consumption of the tire. 4. The thermal conductivity of alloy material is about three times that of steel, and it has good heat dissipation. Therefore, choosing the appropriate wheel hub material and size can improve the driving performance and economy of the vehicle, but we should also pay attention to the advantages and disadvantages of various materials and choose the most suitable wheel.
