Last winter I seen a diesel pusher with super singles in the rear. A lot of over the road trucks are running them but there are very few on MH's. Just wondering why.:h
I failed to mention that the larger a tire surface is causes the tire to act like a ski. In rain, ice and snow you will have poor handling (more than the usual). Also with super singles if you have a flat your down (road service will be paying you a visit).
