Can I get better fuel mileage

[Fergie]

For us they're working. We first tried one in 2009 and saw an increase in mileage. I switched to them to when I saw the increase and the fact we weren't having flats with them like we were with duals. 4 trailers since 09 and we've had 6 flats. 3 needed service truck. I usually have 4-6 flats on the tractor a year. Farm places have lots of nails! I've had service calls on duals to. I've had damage done to equipment from a super single blow, but I've also had damage from a dual tire.
