Odd sight on a semi cab: super-singles all round?

[Espeefan]

I see these a lot, but it really depends on the trucking company. I was just talking to a driver today at work, for Long Haul Trucking. The Pete he was driving had super singles on the drive axles, and on the curtain side trailer. Seems when some companies go this route, they really do embrace the tires for everything, not just the trucks. I'm starting to see these pop up more and more in my area. I think it's cool. Something different and unique. From the side, you really can't tell if they are singles or duals.
