The General RD tire is a regional drive tire that has low rolling resistance for better fuel economy and long tread life for low operating costs. It features an enhanced closed shoulder but high void tread pattern that is proven to deliver excellent mileage, while balancing optimal traction and fuel economy. The tread blocks are reinforced and have grooves that are designed to reduce stone retension. These features make for a longer lasting tire and higher retread acceptance rates for the used casing.
