All of my impliment/flotation tires are tubeless and always will be. I spent more of my life patching tubes... time that I'll never get back... and time wasted. When you reach a certain load factor on an 11L15 they just eat the tube going down the road. Tubeless cures that problem. The downside is that you need to keep the wheels in good condition and painted... which is not really a big deal. Change the valve stems when you install a new tire, etc. As noted, a flat can be fixed with a plug. You also need a bead cheetah or get good with ether to mount/inflate the tires but that's not a big deal. Tubelss tire is a LOT quicker to change/repair. That's why tire shops don't want to see a tube type tire.
