There was a gain in mpg switching to super singles over duels. (.5 mpg ish) Adding balancing beads did not show a measurable increase, but did noticeably reduce vibration. Less vibration will gove longer tire life and probably a small gain in mpg.
Super singles (yes or no)

Carry alot lot of salt with you in the winter. My company truck has great tread if im in the yard and there's ice on the ground I get stuck on flat ground.plus Getting under or out from a Trailer can be a nightmare. The ride is smoother and in a 2007 Columbia I'm getting around 8 mpg hauling water loads. They also are only a 100 dollars more and you buy 4 instead of eight which is biggest reason people buy them I would think.

Get a tire pressure monitor system for them. Good money spent to avoid problems.
Also if you run over 75 mph, I don`t recommend SSs. -
BUT, the op is talkign about use on trailers so all of this is irrelevant since he's not talking about drives. -
A pressure monitor system is a good idea for duels or singles....with singles though, its cheaper. -
When I was in school I did a huge research project on this subject. The real question you have to ask is, "Do I want Fuel Economy and Longevity, or Load dispersion in the event of a blow out. The truth of the matter is there is a larger contact patch and harder rubber used in SS tires and they do not (to my knowledge yet) retread them. When I worked at a truck stop (wrenching) The debate was back and forth. Most truckers liked the increase in fuel economy because on a truck hauling 100plus gallons of fuel they can see a huge difference, some up to 300miles further on a tank. Other truckers all freak out saying they wouldn't want to loose 25% of the load displacement in a blow out, but I always ask what typically causes blow outs. Retread tires, bald tires, and the number 1 is low air pressure. I have talked with all kinds of truckers, from multi-million mile drivers, to rookies. The mistake I have heard over and over again when I did road side calls was, "Darn, I knew I should've checked that pressure before I left!" The only time I changed a SS tire on the side of the road was because the driver drove on the wrong side of the construction cones and picked up a spike. I would say this is an all opinion topic. Kind of like talking religion or politics. To each his own. Your Rig is your home on wheels, treat it how you would your actual home, don't force something down someone's throat cause you feel you are right.

I had one blow on a Peterbilt tri-axle dump truck, right front going 60 plus, took the right side of the nose out, ruined the rim, ripped the mirror bracket off, put a hole in the door and damaged the fuel tank straps, had to lowboy that one to the dealer.
Driver quit after that and my insurance company went after Dunlop, the tire wasn't even a month old.
Never used them on a trailer but i did work for Old Castle in PA and their walking floor trailers had them and they were always getting stuck in the mud, Old Castle fazed them out.nofilter Thanks this. -
Yeah, retreading wide based rubber is big business now.
I have had wide based on my Columbia now for two winters. I never have any issues with snow and ice. I can get in and out of places just as well as when I was running dual. I have had these wide based on this truck from the factory, and now have about 231,00 on them. I took a tread depth gauge to them about 10,000 miles ago, and still had between 18/32 and 20/32 on all of them, with no abnormal wear, cupping, river wear, etc.
Now, It may have something to do with it, that I am using 0" offset wheels. Some have experienced bad wear using 2" off set wheels that have a wider stance. I have an intermediate length axle which is slightly wider than a standard drive axle, but I can still put duals on it if I had to. It more than makes up for any offset wheels. I am also running the balancing beads in each tire. And I generally keep the tire inflation i line with Michelin's recommended pressures. Usually between 95 and 100 psi. Haven't used a TPMS on them, but considering it here shortly, so I stick the tires quite frequently to check that the pressures are where they should be.
Overall, I like them. I will continue to use them.
