A cast wheel is a wheel made from cast metal, typically an aluminum alloy. Unlike steel wheels, which are made from stamped sheets of metal, a cast wheel is more complex to manufacture and offers several advantages over steel wheels.
Cast wheels are usually lighter than steel wheels, which helps reduce the weight of the vehicle and improve fuel efficiency. They can also be available in a wider range of designs and sizes to enhance the appearance and performance of the vehicle.
In addition, cast wheels can provide better driving and handling characteristics due to their higher strength and stiffness. They are also generally more resistant to corrosion and damage from road conditions such as potholes.
A flow formed wheel is manufactured using a special production process in which an aluminum preform is spun under high pressure and high heat while being drawn through a specialized mold. This process creates a wheel with a very strong outer layer and a thinner inner layer, resulting in high strength and stiffness.
The process of manufacturing flow formed wheels is also known as "spin forming" and is a combination of casting and forging. By spinning the blank and drawing the material, the aluminum is compacted and reinforced, resulting in a wheel with high strength and low weight.
Compared to traditional cast or forged wheels, flow formed wheels have several advantages. They are usually lighter than cast wheels and more cost-effective than forged wheels, but offer similar benefits in terms of strength and performance.
Due to their high strength, stiffness, and durability, flow formed wheels are often used in the motorsport industry, but they are also a popular choice for street vehicles seeking improved performance and aesthetics.
A forged wheel is a wheel made from forged aluminum. Compared to conventional cast wheels, forged wheels are usually lighter and stronger. They are often used in racing cars and sports cars to reduce the overall weight of the vehicle and improve performance.
By using forged wheels, the braking performance of the vehicle can also be improved as they offer higher heat dissipation and greater stiffness. However, forged wheels are typically more expensive than conventional cast wheels.
Our symbols are intended to give you an idea of how the weight of the wheel affects fuel consumption. The ratio to the chosen wheel size is always taken into account.
The original alloy wheels are mostly very heavy and usually belong to the category of the highest fuel consumption.
The most obvious distinguishing feature is weight. Lightweight alloy wheels are, as the name suggests, lighter than their heavier counterparts. This can affect various aspects of your vehicle.
In summary, the choice between lightweight and heavyweight alloy wheels is a matter of compromise, depending on your priorities regarding fuel consumption, performance, and cost.
Rear spoke milling is a special machining process applied to the wheel, where material is milled from the backside (inside) of the spoke areas to reduce the weight of the wheel.
By removing material from the backside of the spokes, the weight of the wheel can be reduced without compromising its strength. This results in improved acceleration and better driving dynamics, particularly important for sporty vehicles and race cars.
The offset (ET) indicates, in millimeters, how far the mounting surface of the wheel is from the wheel's center. The larger the ET, the more the wheel sits inward in the wheel arch.
The wheel width is specified in inches. The letter J stands for the type of rim flange design.
Winter-capable wheels have a coating surface that is resistant to road salt and weather conditions, providing protection against corrosion.
The level of detail of a wheel refers to the number of fine details and the complexity of its design. It not only contributes to the aesthetic appearance of a vehicle but also influences its handling and performance.
The level of detail of a wheel is important as it can influence the appearance and perception of a vehicle. The higher the level of detail, the more sophisticated and eye-catching the wheel design appears. However, a higher level of detail and a more complex construction can also mean higher costs.
The lightweight construction allows for faster and dynamic acceleration, due to a lower unsprung mass.
Precise balancing and optimised weight distribution minimise the rim's oscillation behaviour, resulting in improved steering precision, lower rolling resistance and increased responsiveness. This contributes to improved road holding.
