The Hankook Smart Flex DH51 is a drive axle tyre delivering premium performance in all regional haul conditions during the whole tyre life. A wider tread block than the previous product increases the tyre footprint and grip, leading to an improved mileage performance and rolling resistance. The Hankook Smart Flex DH51 tyre features directional v-shaped sipes to enhance grip and regenerate as the tyre wears to give maximum performance even when the tyre is worn.
