What does the 4x108 bolt pattern mean?

The 4x108 bolt pattern indicates that the wheel has 4 bolt holes, and the diameter of the circle on which these holes are centered is 108 millimeters. This is a critical measurement for ensuring the wheel bolts correctly to your vehicle's hub.

What is the purpose of the offset (ET) measurement?

The offset, denoted as ET, is the distance from the wheel's mounting surface to the centerline of the wheel. A 42mm offset means the mounting surface is 42mm outward from the wheel's centerline, which affects how the wheel sits in the wheel well and can influence tire clearance and vehicle stance.

What is the center bore (CB) and why is it important?

The center bore is the hole in the center of the wheel that fits over your vehicle's hub. This wheel has a 63.4mm center bore, which should match or be larger than your vehicle's hub diameter for a proper, centered fit. Hub-centric rings can be used if the wheel's center bore is larger than the hub.
