In the context of wheels, “concave” refers to the inward curvature or shape of the wheel face.
A concave wheel has a center area that is set deeper or lower than the outer edges, creating a visually recessed or “scooped” appearance.

This concave design adds depth and dimension to the wheel, giving it a more aggressive and sporty look.
The degree of concavity can vary, with some wheels having a subtle concave profile, while others feature a more pronounced or extreme concave shape.
The concavity of a wheel is typically measured by the depth or drop from the outer rim lip to the inner hub area.
