01 Step One

Tires should be mounted only according to good tire-mounting practices and on equipment designed for the tire industry.

02 Step Two

Before mounting the tires, lubricate the beadlock bolts with anti-seize.

03 Step Three

Seat the tire bead in the shoulder of the beadlock inner ring on the wheel.

04 Step Four

Install the outer ring. Tighten the bolts in a criss-cross pattern to ensure even pressure on the beadlocks.

Maximum torque should be: 20 ft/lbs 5/16” 12-point bolts

05 Step Five

The outer ring will flex to match the tire bead, and it should pull down to meet the inner ring.

06 Step 6

Re-torque the bolts after initial use.

07 Step Seven

Note that impact wrenches are not recommended for installing bolts due to the possibility of over or under tightening. All bolts should be started by hand to avoid cross threading.
