|In addition to the advantages of durability and beauty, the aluminum alloy rim is also fuel-efficient, heat-dissipating and round.|
1. Fuel-saving: On average, each aluminum alloy rim is 2kg lighter than steel rims of the same size, and 5 cars can reduce 10kg weight. According to the japanese experiment, the weight of a 5-seat car is reduced by 1kg, saving about 20l of gasoline a year. The research report published by the society of automotive engineers pointed out that although the aluminum alloy wheels are more expensive than the general steel wheels, the fuel cost saved by each car when it reaches 20,000 kilometers is enough to offset the cost of the modified wheel.
2, good heat dissipation: The heat transfer coefficient of alloy rims is 3 times that of steel. The heat dissipation effect is good, and the brake disc and brake caliper can maintain excellent braking performance. At long-distance high-speed driving, the tires can also be kept at an appropriate temperature, making the tires less prone to aging, increasing life and reducing the chance of puncture.
3, good roundness: Accuracy of up to 0.05mm, good balance of running performance, is conducive to eliminating steering wheel jitter and tire eccentric wear.
