Saving about 1,000 pounds of weight thus using less gas is one thing. Instead of having two steel wheels per position, you have only one aluminum wheel. There is also reduced friction with less sidewalls also increasing gas mileage. One more thing is that since they weigh less than dual tires, freight amount can be increased in the truck (since we have weight limitations we have to meet in each state).

There are pros and cons to almost everything. These tires haven't really been recommended for LTL as much as for regional or local hauling. Later, QD.
