Its a bead lock, not a run-flat. Are they advertising it as a run-flat?
That being said, you certainly can drive on it, you can also drive on a plain old flat tire if you want. The advantage here would be that it is less likely to spin or pop off while doing so.
Now you'll say that it will ruin the tire doing so. Yes, so will every other run-flat out there. I dont know of any production run-flat system that does not ruin the tire after running it flat. The metal/rubber ones in the HMMWV destroys the tire, the high-end ones on current imports also kills the $400+ tire.
Dual bead lock = good
Run-flats = not so
There are better/simpler ways to bead-lock, but they get kinda pricey. Whats the security worth to you?
