What material does the car wheel have? Which one is good?

 The wheel rim is an important part of the car, also known as the rim.Generally speaking, it is the part of the axle mounted in the center of the wheel.

Automobile wheels are mainly divided into manufacturing processes, namely casting and forging.Generally speaking, the cast ring is aluminum, and the forged ring also has aluminum and titanium.However, in general, forged rings have high strength, cast rings are light in weight, automobile power loss is small, and the running speed is fast.

Another different indicator of the wheel rim is the different hole distance and eccentricity distance.The hole distance is just the position of the screw.The eccentricity distance reflects the distance of therim from the surface of the screw to the centerline of therim.A very good wheel rim requires uniform density, round shape, and good performance.

Car wheels can be updated, and some people will upgrade their wheels.For larger wheels, the outer diameter of the tire remains the same, and the flatness of the tire becomes larger.The lateral swing of the car is smaller and the stability is improved.

However, the car has lost its comfort.The wheels currently used are made of aluminum alloy material, which has a beautiful appearance, but they are also very exquisite. In order to maintain the beauty of the wheels, in addition to paying special attention to preventing accidental damage to the wheels during driving, regular maintenance of the wheels is also required.
