What is the benefit of a knurled bead on a wheel?

A knurled bead is a textured surface inside the wheel rim where the tire bead sits. This texture helps to increase friction, making it more difficult for the tire to slip on the rim, especially under high torque conditions.

How does the flow forming process affect the wheel's performance?

Flow forming creates a stronger and lighter wheel by stretching and compressing the aluminum alloy. This process results in a more uniform grain structure, which improves the wheel's durability and reduces unsprung weight, benefiting handling and acceleration.

What does the ET40 offset mean for my vehicle?

The ET40 offset indicates the distance from the wheel's mounting surface to the centerline of the wheel. A positive offset like ET40 generally means the wheel will sit further inward compared to a zero or negative offset, which can affect clearance with fenders and suspension components.

Product Details

The knurled bead on this Konig Ultragram wheel is a notable design choice, helping to keep your tire seated firmly, especially under hard acceleration or braking. This 17x9 inch wheel features a 5x114.3 bolt pattern and a +40mm offset, making it a solid option for many vehicles looking for a wider stance and improved grip.

Constructed using Konig's advanced flow forming process, these wheels are both strong and lightweight. This method results in a more uniform grain structure in the aluminum, creating a wheel that can handle the demands of spirited driving without adding unnecessary unsprung weight. The Carbon Bronze Metallic finish offers a unique look that stands out from typical silver or black wheels, and the knurled bead adds a functional detail that serious drivers will appreciate.

When considering a wheel upgrade like this, it's important to check compatibility with your specific vehicle's suspension and brake components to ensure proper fitment and clearance. The 17x9 size and ET40 offset are common for many performance-oriented cars and trucks, but always verify before installation.
