The Hankook Kinergy 4S2 is a directional-tread passenger car tire designed to improve driving safety at all seasons. Designed specifically for year-round use in European countries with mild winter weather conditions. 2018 model.
In the lineup, the Hankook Kinergy 4S2 will replace the Hankook Kinergy 4S H740 produced in 2014. Unlike its predecessor, it received asymmetrical directional design, which, by the way, is used for the first time for the all-season of the South Korean brand, despite the fact that this is already the fifth generation of tires for year-round use.
Optimization of the tread pattern not only improved the tire's handling on wet and dry surfaces but also significantly reduced its braking distance in various weather conditions.
The Kinergy 4s2 model is characterized by increased stiffness, precise steering response, as well as reliable traction, says a Shina.Guide technician. A high level of tire rigidity is ensured by a massive block structure and a special arrangement of tread blocks. Hankook's developers ensure that the braking performance of the tire is not affected by thermal conditions, and the shoulder blocks of the tire provide the necessary "grip" for improved handling.
The directional tread pattern of a tire is one of the main factors for safe driving on wet roads. The V-shaped design of the Hankook H750 Kinergy 4S 2, composed of alternating blocks directed towards the center, is a guarantee of excellent road holding of the tire, not only in dry conditions but also in rain.
Wide two-level lateral drainage grooves with two annular grooves quickly drain water from the contact patch, increase the tire's resistance to aquaplaning and increase slush passability.
The additional grip of the Hankook Kinergy 4S2 on wet road surfaces is provided by a rubber compound that contains highly dispersed silica and ingredients from natural renewable raw materials. It should be noted that the combination of natural and synthetic components in the rubber compound had a positive effect on the "dry" grip of the tire.
To optimize grip and increase the contact surface of the Hankook Kinergy 4S 2 with snow, three-dimensional sipes are designed to cut horizontally through the center blocks of the tread. The wavy sipes striving to meet each other shorten the braking distance on snow, and also, oddly enough, reduce wear at high temperatures and increased loads.
The model is equipped with winter tread wear indicators, called Winter Tread Wear Indicators, or WTWI for short. They are located in the grooves of the Kinergy 4s2 tread and allow the car owner to quickly assess the condition of the tire.
The reliability of the grip properties of all-season tires Hankook Kinergy 4S2 H750 on snowy roads is confirmed by the 3PMSF pictogram (snowflake against the background of a three-peaked mountain) on the sidewall.
Updated. In 2019, the manufacturer announced the launch of an SUV version of the H750. She was named Hankook Kinergy 4S2 X H750A.
It is noteworthy that at the moment the all-season tire segment has received serious development. The fact is that such rubber has become of better quality, so motorists began to trust it. Previously, all experts were inclined to believe that the "all-season" does not provide that grip on the snow, as winter tires. And that was true, but now everything has changed for the better.
State-of-the-art all-season tires such as the Hankook Kinergy 4S2 provide superior ride quality on all surfaces. Now motorists who use such tires do not need to change their cars twice a year, spending a lot of money on it.
The Hankook Kinergy 4S2 combines the benefits of summer tires - optimal wet and dry handling (also in high summer temperatures) and short braking distances - with winter tires, providing high traction and braking performance in cold and snowy conditions.
The new generation of Hankook all-season rubber has received an asymmetric tread pattern with a "summer" shoulder zone characterized by large blocks, between which there are step ties to improve ride characteristics on dry surfaces and high temperatures. The stability of movement is provided by five ribs of the tread, while the precision of control is achieved by special sipes on the outer area of the blocks.
A wide belt and a silica compound are used to improve the wear characteristics and strength of the tire. Kinergy 4S2 has excellent aquaplaning resistance and effectively removes water and sludge from the contact patch due to the tread, which is combined with four main grooves and side grooves that slope out of the main grooves.
The inner tread area has a large number of sipes and blocks, providing more effective braking in autumn and winter. The crisscross V-shaped grooves provide precise handling on snowy surfaces. In the tread grooves, there are wear indicators at equal distances, so that the owner can easily determine the conformity of the pattern depth to the winter period.
At the first stage of sales, the new Hankook Kinergy 4S2 tire will be available in 45 sizes (14-18 inches) in three-speed indexes - T, H, and V. The tires have been certified, received the M + S marking, and the snowflake symbol, and were also tested leading German premium car manufacturers.
