Van Wyk came to the same conclusion with the super singles. They didn't last as long as they were supposed to, didn't get the advertised MPG increase, some late loads & costly roadside service when one would blow out 200 miles from the nearest shop that had a replacement (and an alloy rim) in stock. Uneven tread wear, drivers complaining they had no traction in snow, etc.
And that was with the auto-inflation systems on the trailers & cat eye monitors on the drives.
They ran that equipment out til trade but went back to duals on new orders.
They made a similar decision to dump either the tails or the skirts recently but I can't remember which one. I hope it was the tails because they're a pain in the ass in the winter when snow gets on them. And they look stupid too.
The only thing about the skirts I don't like is on some of them, to make room for the skirts they mounted the reefer tanks too far from the edge and it can be a pain in the ass to get the fuel nozzle in them.
So... what kind of tires and model were they using? Not all wide singles will deliver the performance increase.
