Hub centering and offset
Hub centering is the first thing to settle with a wheel that has a larger center bore. Hub-centric rings fill the gap between the bore and the hub so the load sits on the hub rather than the lug studs, which keeps vibration down and protects the studs over time.
Offset and backspacing decide where the wheel sits in the fender and how much room the brake caliper and control arms get. Off-road tires run wider than the stock setup, so measure clearance at full steering lock and at full suspension travel before the first trail run.
- Measure caliper clearance with the wheel mounted
- Check spring and shock height after a lift
- Torque lug nuts in a star pattern and recheck after the first drive

Installation notes
Compare the 108 center bore with your hub. A bore larger than the hub needs hub-centric rings to center the wheel, and the offset and backspacing determine how close the wheel sits to suspension and brake parts.
