As an important part of automobiles, the design of the wheel rims has a great influence on the beauty of automobiles.

Purpose of automobile rim modification

The enlargement of the rim must be matched with the change of the tire. In addition to the aesthetic factors, the rim is modified to achieve heat dissipation and is lightweight. The rims made of aluminum alloy or magnesium alloy have better heat dissipation than iron rims. If they are matched with the special shape of rims, they can have a better cooling effect.

Compared with steel rims, aluminum alloy rims have the following advantages

Rims can be divided into aluminum alloy rims and steel rims according to different materials. In addition, there are plastic rims with a novel appearance (not popular, only used for minicars). The most popular rims are of course aluminum alloy rims, and magnesium aluminum alloy materials are also used in racing cars.

1. Good cooling effect. The aluminum alloy rims have large strength, narrow spokes, and a more free shape. They can leave more space for ventilation, and accommodate large brake calipers and brake discs, which can effectively cool down; Second, aluminum alloy is good at heat absorption and heat dissipation, which can absorb the heat from the brake disc and distribute it to the air.

2. Lightweight, fast acceleration. The rotation inertia of aluminum alloy rims is much smaller than that of steel heavy rims, so installing aluminum alloy rims can make the car's acceleration, turning, and braking more sensitive, and the light rims can make the car accelerate faster.

3. Good comfort. In addition to the performance of aluminum alloy rims on flat roads, lightweight rims can also improve the comfort of vehicles on bumpy roads.

4. Good rigidity. The high hardness of the aluminum alloy rim significantly reduces the inclination of the tire/rim when cornering.

5. Good grip. Aluminum rims reduce the unloaded weight and thus improve the grip. As the road vibration and steering forces are very sensitive to the non-load weight, the aluminum alloy rims also show better bending performance and more accurate steering action.

Maintenance of modified rims

1. The beauty of the rim has a great impact on the beauty of the car. Car rims are mostly made of aluminum alloy. To maintain the beauty of aluminum alloy rims for a long time, the rims must be thoroughly cleaned every 2 weeks to remove the dirt, salt, and residue of brake pads attached to the rims. Otherwise, once the stubborn dirt sticks to the rims, it is difficult to remove it.

2. The paint on the rim should be as meticulous as the paint film on the car body. After cleaning with neutral detergent, care with rim cleaner to remove asphalt, rust, oil stain, etc. on the rim surface. However, abrasives or paint brighteners shall not be used for rims. If the aluminum alloy protective paint on the rim is scratched by hard objects during driving, the aluminum alloy rim shall be repaired and repainted as soon as possible.
