Hankook Kinergy 4S H740 Maximum performance for a balanced driving experience in all-season use. 10% reduction in braking distance and 6% improvement in wet and dry handling (compared to the previous model). The use of two different types of sipes (inner/outer), allows the tire to have high summer performance (inner) and at the same time very good winter performance (outer). Features Specified cross grooves (deciduous style)The wide cross grooves, in conjunction with the stepped cross bars, create optimal drainage channels. The reduced ground contact pressure allows for optimized displacement of water and snow. The wide cross grooves also ensure the very high traction performance on snow. Summer sipesThe use of two different sipes (inner/outer) allows the tire to combine high summer performance (outer side) and very good winter characteristics (inner side). A 3D sipe blocking system, progressively supports the tire even in bad road conditions, by increasing the block stiffness. Needle-shaped cross grooves (conifer style)Main cross grooves with a high overlap angle, provide max traction and braking performance. This has been significantly optimized again for use on different road conditions. Tire construction High grip silica compound Improved snow and wet traction, and significantly reduced rolling resistance. Seamless, reinforced belt cover Guarantees high tread strength 2 wide steel belt plies Guarantee, in conjunction with the stable sidewall, a long service life. Balanced polyester carcass line Improves sidewall stiffness and resistance. Use of special bead fillers Improved handling and steering response. Ultra strong bead core Improved uniformity and maximized fit on the rim.
