I came across this interesting semi-tubeless set up on ebay.
Looking at it I'm thinking that you could maybe fix a puncture in the tyre with a tubeless plug the hole type repair kit, so you wouldn't have to take the wheel & tyre off ?

they work great....
6/8psi the tyre just raps around what ever is under it
with a massive contact patch....unbeleavable traction
on any terrain...
i have not used a front one though...

i would not use them on the road...
