Overview
The Pro Comp Series 75 Trilogy Race Beadlock in 17×9 inches is a satin black aluminum wheel, part number PXA5175-798337M, drilled for a 6 on 5.5 bolt pattern with a 108 center bore. It belongs to the 75 Series, a beadlock design for trucks and SUVs used in demanding off-road conditions.
The wheel has a -30 offset, which places the mounting face behind the centerline and moves the wheel outward from the hub. The 3.75 backspacing is the distance from the mounting face to the back edge of the rim, which sets the room needed behind the brake and axle parts. The offset is -30mm, so compare that figure with your vehicle.
A beadlock wheel holds the tire bead against the rim with a locking ring, which differs from a standard alloy wheel. Confirm the locking hardware and bead seating needs for your tire before ordering.

Beadlock tire setup
Beadlock wheels are used when the tire needs to stay seated at low pressure. The locking ring grips the bead, so the tire does not roll off the rim during hard articulation. Pressure, tire choice and ring fit all affect that outcome, so set them up together rather than one at a time.
Inspect the bead seat, ring and mounting bolts after trail sessions. Look for scoring on the bead surface, cracks in the ring and any looseness. Replace worn parts before returning to trail use, since a failed ring can release the tire.
The -30 offset and 3.75 backspacing set how the wheel sits against the brake caliper and axle components, so check clearance with the suspension compressed and at full steering lock.
- Check the locking ring after each trail run
- Verify bead seat before airing down
- Confirm caliper clearance with suspension compressed

Vehicle fitment
Confirm fit for your vehicle’s year, model and trim before ordering. The 6 on 5.5 pattern and 108 center bore must match the hub. The -30 offset governs how the wheel sits relative to the fender and suspension. Beadlock wheels are often used for low-pressure trail running, so confirm that the tire and locking hardware fit before ordering.
