Super Singles
We have tried super singles on 10 trailers, however, the biggest problem is finding a replacement tire on the road, and the price of it (not cheap, and often hard to find, and if you damage a rim too, it gets even steeper.) Seriously considering back to dual's for next round of trailers just because the cost benefit has not been seen thus far and we have had them for 2 years now. If you do get them, definitley go with auto-inflation system for the tires, it will at least get you to a place where you can get some repairs done if needed assuming the tire is not cut or beyond repair on the side of the road. Another thing we are still tweaking with is what PSI to run them at as it greatly affects the tire ware. We have had some O/O's convert their tractors and are very happy with them, just disappointingly expensive if there are any issues on the road.
