    A 17 in. x 8 in. N91 aluminum wheel for 5x4.75 in. bolt circle applications. The 72.60 mm center bore is sized for hub-centric mounting, so the hub carries the load instead of the studs, and the gunmetal finish with a machined face gives a two-tone look without paint. Good choice when you want a larger diameter for brake clearance and a modern face.
