Hankook Tire has been contracted to supply Ford with all-season tires for its Super Duty F-450 and F-550 Chassis Cab. The SmartFlex AH35 and DH35, which is the latest model to have been added to Hankook’s growing US TBR portfolio, will be factory fitted in size 225/70 R19.5.
“The Ford F-450 and F-550 deliver excellent handling performance so it was essential for us to find the optimized balance between the tire’s tread compound, patterns, block size alignment and dimension to enhance block stiffness to find that perfect handling performance,” explained Youngjong Kwon, head of R&D in the truck and bus development department.
The SmartFlex AH35 and DH35 feature specially designed treads that are said to deliver low rolling resistance and excellent driving performance.
In the case of the AH35, the multi-3D sipes anchored in the tread improve traction. The combination of straight and wave-shaped grooves improve water run-off and prevent aquaplaning. The stiffness of the tread blocks promotes more fuel-efficient operations while the special tread design also supports even wear.
The tread of the SmartFlex DH35 meanwhile covers a wide contact area and has four zig-zag groove lines across the whole tread surface, which gives more mileage and better driving performance in various road and traffic conditions.
“Ford has always been at the forefront of innovation with its heavy-duty trucks, and the F-Series is no exception. It has exceptional endurance and performance capabilities,” commented Hyunjun Cho, head of the Hankook OE tire division.
“We are thrilled to be able to continue our relationship with Ford and its top-rated 2020 Super Duty line of trucks. Being chosen as the original equipment tire to one of the best-selling auto makers will enable us to solidify Hankook as a leader in global tire making.”
