The reduced rolling resistance in the Firestone FT455 Plus tire offers fuel economy that satisfies the requirements for EPA SmartWay verification and CARB compliance. Body ply with special casing contour and steel belts ensures the longevity of casings and superior retread performance. The flow-through treads evacuate water for better wet traction and promote smooth rib wear patterns. Four full-width steel belts reduce tread squirm for improved durability of the casing.
