Re: \"tirelock\" internal beadlocks
I looked into these extensively, and would go that route if/when I go to beadlocks if I could afford it. I run my SXs at 5psi without beadlocks and have never blown a bead, but I'm not doing an ARCA competition!
locks BOTH beads. Most beadlocks only lock the outside bead, although losing an inside bead is rare.
shouldn't leak. Many beadlocks leak air, making them harder to live with for something that DOES see some road action.
takes up some volume in the tire (this is my favorite). Ever try bleading/filling a large swamper? Takes a long time. I remove the core to get the air out and have a power tank to get the air in. The tire loks take up a considerable amount of the internal volume of the tire, so as a result it takes considerably less time to air down and up. If your rig is trailered everywhere all the time this is not a big consideration, but for me it is.
can run like a run flat system. This is either good or bad depending on your point of view (there is no sensor, so potentially you could be running flat without knowing it. Of course, with swampers this is pretty much true anyway!)
transferable - change rims? if the rims are the same width and diameter you can just move the system to the new set of rims.
expensive. This is the big disadvantage for most people. It is NOT actually more expensive than dual bead locks (that lock both inner and outer beads), but dual beadlocks are rarely used. Compared to the regular outer lock only, they are considerably more expensive.
mounting. Mounting is more difficult because you have to take special care to not pinch the inner tube. In addition, regular bead locks generally make mounting a tire on the trail a lot easier because you don't have to get the tire lip over the rim, whereas tire loks don't have that advantage.
balancing? I have no idea if these things would make balancing the tire easier or more difficult, but for me personally this is a moot point - trying to balance swampers is a joke to begin with.
availability/support. Not too many distributors, who knows what kind of tech support (if any) that you get.
That's all I can think of off the top of my head, hope this helps.
