The Coyote Boltless Beadlock heavy duty inner tube, CET03, fits 14inch beadlocks. It is sized to fit tightly against the drop center of the rim so it is smaller than a normal tube for 14 inch rims.
Since your Coyote Boltless, Dual, Internal, Pneumatic Beadlock is a tubeless wheel, these specially made inner tubes have an all-thread valve stem with O-rings inside and out to prevent air from leaking at the valve stem.
It comes with all necessary mounting hardware including a packet of talcum power!
