Hankook Tire’s Ventus S1 evo Z UUHP tires (Ultra-Ultra-High-Performance) was chosen as original equipment tire for the BMW X3 M and X4 M.

The brand new Hankook Ventus S1 evo Z, which is fitted ex works, was specially developed for the UUHP segment for use on particularly sporty high-performance vehicles. The Hankook Ventus S1 evo Z is available for both BMW M GmbH models in 255/40 ZR21 102Y tires on the front axle and 265/40 ZR21 105Y on the rear axle and has been adapted to the specific requirements of BMW M GmbH.

“Our company was founded 80 years ago,” says Sanghoon Lee, President of Hankook Tire Europe, “So it’s certainly a special gift that our latest product has been able to win over BMW M GmbH, a particularly prestigious customer from the sports car manufacturer segment.”

For this highly demanding vehicle segment, especially when it comes to tires, the Ventus S1 evo Z has been equipped with an aramid composite material in a double-layer carcass. This prevents deformations caused by possible heat development during extensive use. Deformations would otherwise lead to an undesired increase in the rolling circumference and less precise handling at high speeds. The new Hankook tread pattern gains additional stability from high-strength steels in the belt and bead areas, which, in combination with the reinforced sidewall, ensure straight-line stability and steering precision, as well as sporty, dynamic handling.

Another focus when developing the Ventus S1 evo Z was on high grip in different weather conditions. The tread compound used is borrowed from Hankook’s motorsport research and development. For an optimal interaction of fillers, silica and natural resins, the latest generation of functional polymers have been used in the mixture. This ensures a consistently high level of grip across a wide range of applications.

Often seen with particularly sporty treads, the Hankook Ventus S1 evo Z also uses an asymmetrically designed tread pattern. The arrangement of the individual tread blocks has been developed to ensure optimum block stiffness under various driving conditions. Three main drainage grooves positioned in the inner tread area ensure water is drained efficiently in wet conditions. In addition, special attention has been paid to the outer tread area of the tire, where a significantly increased proportion of tread takes into account the requirements for high-performance cornering and precise lateral guidance, particularly for very sporty driving in dry conditions.
