I am thinking about putting a set of all position tires on my drive axles for a increase in fuel mileage. My question is has anyone out there done this, if so what brand / model would you or did you go with and what kind of life did you get out of them? I want to try to figure out if it will be worth it and what kind of savings I will be looking at. I don't run that much in the winter so traction shouldn't be to big of a issue. Thanks for the info. Or should I just bite the bullet and go to the super singles?
