Summary: At 48 PSI, your tires do not have bead problems! You
may have traction problems, but the tire, bead wise, is perfectly
happy with 48 PSI. Our tests proved it (see
tests).
How: As the BeadLock's inner tube inflates through its own
valve stem (not shown), it expands until it reaches the limits of
the polyester profiling Cap. This is like a mini-tire.
That's why we gave the parts tire names. The hefty
polyester Cap "tread" keeps the tube close to the rim thereby
dictating a very low profile. The Cap sidewalls, in turn, keep
it from touching the remaining portion of the tire. This
eliminates scuffing and rubbing, hence no BeadLock-to-tire heat or
wear is produced (details). The remainder of
the tire's air chamber is available to deflated to your desired pressure through the special valve stem
(details).
Tests: Our tests were run at
flat! In other words, the space above the bead lock accommodates low pressure
flex down to zero PSI . Our test tires, flat, both knowingly
and unknowingly, did not come off the rims. This gave us "low
pressure" peace of mind, because 1 1/2 or 2 PSI is
legitimately questionable for most folks. When properly
installed and
inflated to 48 PSI, our internal dual bead locks kept the tires on the rims
and prevented rim spin.
This was for all test cases so far (March-2-05), regardless of the pressure
in the main air chamber. You can personally flirt with your own
low
"pressure poison," but we recommend carefully, and we're anxious to
hear of your results!
Strap effect: The force arrows above
show how the tube securely "straps" both tire beads firmly against the rim.
Extra force: A conventional tubeless tire
secures the beads against the
rim in the same way - air pressure, but surprisingly enough, the
Staun BeadLock™ provides more holding force. The tube, in conjunction with the Cap, adds additional holding force
below the tire bead not
just at and above the bead. The air pressure in the
tube acts like/is a "strap." This puts additional bead holding force
against the rim that is beyond just the bead lock bumps. This is exactly why some tire
experts recommend that you run tubes in tubeless tires if you air
down. They can see that a tubeless
tire with no tube does not have this lower strap. The top part of
the strap is there by virtue of the tire, but there is nothing
beneath the bead to complete the strap effect. The Staun
BeadLock™ straps the tire to the rim better than a tubeless tire
alone.
Conclusion: The 48 PSI "strap" produces
a massive holding force that firmly secures both tire beads to the rim
bead seating area.
