Why are so many trucking companies switching to single rear wheel on class 8's?
Some do it for the weight saving. The super single is lighter than 2 regular wheels & tires. Less truck weight equals more billable payload. There is also a slight reduction in rolling resistance. And if you run enough miles you save fuel. But I do know of some companies who switched back because of the costs of wheels and tires do to flats. If you have a flat a speed, you can't stop fast enough to not ruin the wheel also.
