HOW THEY WORK

The Coyote Dual, Boltless, Internal, Pneumatic 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's main air chamber and the other is 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 bead lock Case forces the Case to take shape and do its job. The inner tube is inflated up to 50 PSI (max) and forces/pinches both tire beads against the rim. On a 15 inch rim, we calculate that there is over 9,000 pounds of force holding both beads against the rim! This is in addition to the force required to pop the beads over the rim’s bead bumps. Through a standard valve stem fitted with an Air Channel, a "snorkel" of a sort, the balance of the tire can be inflated or deflated to any pressure less than 45 PSI (max).

THE ADVANTAGE

• Coyote Boltless Beadlocks have several advantages over conventional, mechanical beadlocks.
• You can use your existing rims, conventionally beadlocked or not.
• They lock both the outside and inside tire beads to the rim. So, contrary to what happens with conventional, mechanical beadlocks, this prevents the inside tire bead from burping air.
• They provide a 3 inch high, 50 PSI “bump stop” that reduces rim and tire damage in demanding applications like Baja 1000 and Hammer racing.
• There are no balance issues.
• There are no DOT issues. They are street legal.
• There are no bolt circle torque maintenance requirements.
• They give you a “limp flat” capability to get back to camp or off to the side of the trail for a safer setting to change to your spare.

How does the Coyote Internal Pneumatic Dual Bead Lock made by Coyote Enterprises work?

The Coyote Internal Pneumatic Dual 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's main air chamber 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 (max) and forces/pinches both tire beads against the rim. 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 (max).

What are the advantages of Coyote bead locks over mechanical bead locks?

There are several advantages over conventional, mechanical beadlocks. You can use your existing rims. They lock both the outside and inside tire beads to the rim. This prevents the inside tire bead from burping air. They provide a 3 inch high, 50 PSI "bump stop” that reduces rim and tire damage in demanding uses like Baja 1000 and Hammer racing. There are no balance issues. There are no DOT issues, hence they are street legal. There are no bolt circle torque maintenance requirements. They give you a “limp flat” capability to get back to camp or off to the side of the trail for a safer setting to change to your spare.

Can I use Coyote bead locks in my existing rims and tires?

Yes. They can be fitted to virtually any alloy or steel rim, conventional mechanical beadlock or not.

What size rim will the Coyote beadlocks fit?

Coyote Enterprises makes bead locks to fit rims 14, 15, 16, 16.5 and 17 inches in diameter and from 7 to 10 inches wide.

Are the Coyote bead locks tire specific?

The bead locks are rim size specific, but regarding the tires, no. If kept properly inflated, the beadlock will last you through many sets of tires. However, the inside of all tire beads must be rounded to prevent cutting the inner tube in the mounting process. See the installation manual or video.

Are Coyote beadlocks street legal?

California Highway Patrol Public Relations officer Chris Johnson found that there are no California Vehicle Codes prohibiting the use of Coyote bead locks in California. Federal government wise, he reports that there are no DOT, NITSA and NHTSB regulations or requirements prohibiting the use of Coyote bead locks either. The DOT looks at the Coyote beadlock as an inner tube. Check with your state's Department of Motor Vehicles regarding Coyote beadlock legality in your state.

How about wheel balance?

The Coyote bead lock is almost totally symmetrical from inside to outside and around the rim. Further, all of the weight is located within and near the center of the rim minimizing its affects on balance. The minor Tread overlap weight can be off set by placing it opposite the Air Channel and shown in the installation manual and installation video.

How much do Coyote beadlocks weigh?

Depending on size, each complete bead lock (case, tube and Air Channel) only weighs 6 to 7 pounds.

Can they be used with internal shot or powder balancers?

We conclude from several competitive test applications where lead and steel shot was added for traction that internal dynamic balance devices do not affect bead lock reliability or function. Customers report using powder and shot balancers with no issues, too. However, with these smaller, more mobile items, the issue is not bead lock function, but will they eventually clog the Air Channel or valve core with frequent airing up and down?

Are Coyote beadlocks run-flats?

Definitely not! They are designed to keep the tires on the rims, but not sacrifice your ability to air down. A run flat does not allow this. Run flats inflate up to within a fraction or an inch of the inside of the tire tread preventing airing down. The best Coyote Enterprises will give its beadlocks is a “limp flat” capability. You can limp off the trail or back to camp to make a safer change to your stare.

How far can I drive on a "limp flat"?

Obviously, it depends on the age and condition of your tire, the terrain you are driving over, the weight of your vehicle and how fast and hard you drive on the limp flat. We have several reports of limp flats holding up on the trails all day with unknown flats. There was another report from Australia where the 4X was driven on the freeway for 20 miles at 60 MPH with a flat. The beadlock and rim survived, but the tire was thrashed. We have other reports of failure within a mile or two. As best we can tell from analyzing the failures is that it depends on how much the weight of the vehicle collapses the tire’s sidewall.

How fast can you drive with a Coyote bead lock?

Internal bead locks are being used in drag race vehicles in excess of 150 MPH and have been on the Baja 1000 Jeep Speed class winner for five years in a row. They have also been on Paris to Dakar and Outback Challenge winning vehicles throughout the world.

How new are internal bead locks?

Internal beadlocks were invented in about 1994 for use by the Swedish military and these were introduced into the USA in about 1996. Staun introduced its first beadlock into the USA in 2005.

How easy are Coyote bead locks to install?

You are basically installing a tire within a tire and that is very unfamiliar to most. Although it is neither rocket science nor neurosurgery, there is a learning curve. Most experience tire installers will take about an hour on the first one and by the time they get to number four, it will only take about 20 minutes or so. The important thing to remember is to pay attention to all of the details and that just improves over time.

Can I use CO2 in my tires and Coyote bead locks?

Yes. CO2 is virtually completely inert, so it will not affect the inner tube or the beadlock Case. Although it's a common question, CO2 is what's in our soft drinks and it is actually put in bags of potato chips to keep them fresh and obviously, this has not created any "CO2 people" problems. If it does not affect our bodies, then it is certainly safe for rubber and the Case materials. It's interesting how they get the CO2 in the chip bag. They actually put a tiny pellet of dry ice (CO2) in the bag which turns to gas displacing the air and keeping them fresh, longer. Further, the inflated bag somewhat prevents crushing the chips.

How long do Coyote beadlocks last?

Since the product is completely contained within the tire, they never see deteriorating ultra violet radiation or ozone. These are the two principle contributors to the product’s material failure. They should last indefinitely and through many sets of tires.

Are Coyote bead locks guaranteed?

Yes. There is a 5 year limited warrantee on material and workmanship and 1 year on the inner tube. What Coyote does not cover are improper installation, pinched inner tubes or mis-drilled holes in rim.

On what kind of terrain have Coyote beadlocks been used?

Name it: rocks, sand, mud, snow, drag race tracks, oval race tracks, rally races and more. The bead lock is within the tire and really cannot tell what’s happening on the outside of the tire.

How do Coyote beadlocks affect air up and air down time?

If you use standard valve stems, you will most likely not see much affect and most likely, you will see a decrease in air down time. Consider this. The bead lock occupies approximately 7% (44" tires) to 30% (31" tires) of the tire’s total internal volume. This means you are inflating and deflating a smaller volume, but the Air Channel does slightly slow air movement, so draw your own conclusions.

How much do Coyote bead locks cost?

Coyote bead locks are about the same price as conventional, mechanical bead locks, but more than twice the product. In addition to the outer tire bead, they also lock the inner tire bead and provide a "limp flat" capability. They also offer a 50 PSI bump stop that reduces rim and tire impact damage. Further, since they are not tire specific, they can be used on many sets of tires or transferred from rim to rim.

Coyote bead locks look simply like some material and an inner tube. How come they cost so much?

At first glance, we agree, but there’s a lot more there than meets the eye. Due to the material waste in the Sidewall shape (you’re cutting a ring out of a square) and discarding the center of the "donut", the material accounts for about two-thirds of the manufacturing cost. And the nine times stronger yellow Tread webbing also contributes to high material costs. Look at it this way: It’s about the same price as a mechanical bead lock and more than twice the product as discussed above!
