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

The knurled bead is a textured surface inside the wheel where the tire mounts. This texture helps to grip the tire bead, reducing the chance of the tire rotating on the wheel under hard acceleration or cornering.

What does the ET40 offset mean?

The ET40 offset refers to the wheel's position relative to the hub mounting surface. A positive offset like ET40 means the mounting surface is closer to the outside of the wheel, which can affect how the wheel sits in the fender well and clearance with suspension components.

Does this wheel come with a valve stem?

This product listing is for the wheel only. A valve stem is typically sold separately and is required for proper tire inflation.
