20×8.5 Inch Chrome Finishing Forged Aluminum Car Wheels

Although wheel replacement is often done at the behest of the car owner, for example, to dress up or to further enhance the performance of their car, there are also times when replacement is necessary for safety and security reasons. This is when there is a problem with the condition of the wheel.

First of all, the wheels deteriorate. Although they are long-lasting components, wheels are also wear and tear items. The main materials used are steel and aluminium alloys, which can bend and distort throughout driving. In addition, steel wheels can rust and aluminium wheels can corrode as the clear paint or paint that protects the surface peels off. Anti-icing agents (snow-melting agents), especially in snowy areas, can hurt the paint and lead to wheel deterioration. If these wheels deteriorate, replacement is recommended.

More urgent is damage to the wheel, such as heavy scratches or cracks. Tyre air can escape from the damaged area, so it should be checked if you hit a kerb vigorously in a parking lot or hit a stone or other object on a rough road. If significant damage is found, the wheel needs to be replaced.

Benefits of wheel replacement

Improved driving performance

When steel wheels are replaced with aluminium wheels, the unsprung weight, which is the combined weight of the tyres and wheels for the same size, is reduced, and you will experience improved dynamic performance, such as nimble, sharp manoeuvrability and agile vehicle movement. You can also expect improved acceleration performance and better fuel economy due to the reduced weight.

Dress-up effects

By replacing the wheels with wheels of your favourite design, you can achieve a highly satisfying dress-up effect. Wheels are 'large parts', so even if they are the same size, a different design can change the impression they give. In addition, changing to larger-diameter wheels will give you a powerful and high-impact image change.

Draw out the performance of the tyres

Lightweight aluminium wheels with excellent rigidity and strength enable the performance of the combined tyre to be fully demonstrated. High-quality wheels enable both high-grip sports radials and smooth and comfortable comfort tyres to perform to their full potential.

 

 

Advantages & disadvantages of inch-up and inch-down

Now, when replacing wheels, it is important to check carefully about the sizes mentioned above, but there are also cases where you may want to change the size from the original wheels. What is the purpose of choosing a different size? Here, we will introduce the advantages and disadvantages of the inch-up and inch-down options, which are to increase and decrease the diameter of the tyre by changing the flatness of the tyre without changing its outer diameter (outer size).

Inch-up

Inch-Up' is the process of changing to a wheel with a larger diameter than the factory one without the tyre protruding from the wing or interfering with the wheelhouse. It is one of the most popular car customisations, and many people first decide to inch up their car when they get it.

Inch-up requires new tyres because the outer diameter of the wheel changes, but the outer diameter of the tyre cannot be changed. Therefore, tyres with a lower flatness ratio (cross-sectional height (H) / cross-sectional width (W) x 100) are used. The outer diameter of the tyre is kept the same by reducing the thickness of the tyre to compensate for the increased wheel size.

Advantages of inch-up

Larger diameter wheels increase the power of the exterior and give a more stylish look. This should be taken into account when choosing a wheel with an inch-up design. Changing to tyres with a low flatness ratio also makes the tyre sidewalls thinner and reduces tyre deflection. This results in improved handling response, cornering performance, braking performance and high-speed stability.

Disadvantages of inch-up

While it improves driving performance and handling stability, the reduced deflection of the tyre may result in a firmer (worse) ride. A wider ground contact surface may also increase driving noise. In addition, larger diameter wheels and tyres generally lead to an increase in weight, which in turn reduces acceleration performance and fuel economy.

 

Inch Down

Replacing a wheel that can be fitted where conditions permit with a type that is smaller in diameter than the previously stock wheel is called 'inch-down'. To match the change in wheel outer diameter, tyres with a higher flatness must be used. Contrary to 'inch-up', the smaller wheel diameter results in a thicker tyre.

Reducing the wheel size (inches) basically lowers the price of the tyre, so many people tend to 'inch down' when fitting studless tyres.

Advantages of inch reduction

Highly flat tyres provide a more comfortable ride due to the increased cushioning provided by the increased tyre thickness. The increased cushioning of the tyre also makes it more receptive to road conditions, which reduces the load on the tyre and wheel, especially on rough surfaces and when riding over bumps, making them less susceptible to damage. The narrower road contact surface tends to make them less slippery, especially on wet or snow-covered roads.

Disadvantages of inching down

Although the volume of the tyre with a greater presence is sometimes preferred, generally speaking, if the wheels look smaller, they lose balance with the car and don't feel as smart. Also, tyres with a high flatness ratio will deflect more, so you may easily feel a loss of stability when cornering.
