NIC - Glad your tubeless tires are working for you.
From about March 1979 till the end of Dec. 1981 I was tire buyer/scheduler at FARMALL, we were making 140-150 large farm tractors a DAY. Biggest complaint our QA dept. got from dealers & customers was the fact we used tubeless frt tires, 15,16, 16.1, & 20" rim diameter, and four part numbers of tubeless rear tires, they were 15.5X38 6PR R1 & R2-0 tread, and 18.4X34 6PR R1 & R2-0 tread. Those 4 sizes of rear tires accounted for maybe 8-10% at most of our over-all tire usage, even less when the 686/H86 model was discontinued in 1980, and resulted in well over 60-70% of the tire rework we had to do on brand new tractors, new tires/wheels/rims. The tubeless frts were even worse. Tires were mounted about a half hour before the tractor rolled off the assembly line, and at least every day there were a couple tractors sitting in the yard on flat tubeless tires that had to be fixed before the tractor could ship. The guys mounting the tires mounted 200-300 tires in an EIGHT HOUR shift. They knew how to mount tires, no time for special sealants, wire brushing new rims, etc. On the tube-type rears which everything else used, I bought 2-3 dozen 18.4X38 and a dozen 20.8X38 inner tubes for tire repair a month, maybe a bit longer, they were ordered via the "Hollar System", the tire room forman Hollars, and I make the tubes appear the next day. So by percentage, tire repairs on tube types were REALLY Low.
So my scope of experience covers roughly TWO MILLION tractor tires. That's why only my cars, truck, and tandem axle dump cart have tubeless tires. I'm just atating MY reason for being so adamant about using inner tubes. You all go ahead and make your own decisions. I'll state my experience and YOU decide. I really don't care WHAT anybody else does.
I somewhat agree and also disagree with your other comments. Such as valve stem alignment, there's a right and wrong way to install a tube, the valve stem hole in the rim is off-set and so is the valve stem on the tube, it may not exactly line up but will be close enough to fit fine and work well. Slipping a tire bead on a rim does shear off inner tube valve stems, but a tubed tire is less prone to that than a tubeless tire, and if you do slip a tubed tire on a rim you're running way too low of PSI.
Putting fluid in a tubeless tire is just dumb. Yes, many do it and get by with it, but it gets REAL messy when it does fail for whatever reason. Even fluid in a tube is a PITA to work with, that's why ALL my tires are now dry, took the fluid out of the last two rear tires on the Super H with CaCl 2 yrs ago.
And a 10.00X20 truck tire tube on a real snowy steep hill trumps a tube on a river IMO.
