INSTALLING COYOTE BOLTLESS BEADLOCKS VIDEO

The Coyote Dual, Internal, Pneumatic, Boltless Bead Lock is a tire within a tire. It divides the tire’s air chamber into two separate compartments and thus has two valve stems. One is for the tire and the other for the beadlock. Think of the beadlock Case as a mini-tire and hence its parts are named the same. There is a Tread, two Sidewalls and two Beads. A heavy duty inner tube within the beadlock Case forces the Case to take shape and do its job. The inner tube is inflated up to 50 PSI and forces/pinches both tire beads against the wheel. On a 15 inch wheel, we calculate that there is over 4,500 pounds of force holding the beads against the wheel! This is in addition to the force required to pop the beads over the wheel’s bead bumps. Through a standard valve stem fitted with an Air Channel, the balance of the tire can be inflated or deflated to any pressure less than 45 PSI. Watch the video to see exactly how.

DEFLATOR COMPARISON TEST

Automatic tire deflators are popping up all around the world. They vary in size and shape, and some look virtually identical to the original Staunies (front and center). My objective was to see how they worked compared to the Original Staun® Tyre Deflators. And since I was not in on the other manufacturers’ design, I cannot say what their design objectives were or if the test units were working properly. All I could do was report how they worked for me. The videos present that information.

DEFLATOR FAQs

You simply screw all four Coyote deflators on to your standard tire valve stems and either drive off (Coyote’s only) or wait for them to stop deflating, remove and then move out. We do, however, recommend that you remove the deflator at the first opportunity to avoid damaging either the tires’ valve stems or the deflators. Drive off with the original Stauns, manufactured in Australia, and you void the warranty.
