Hankook will be launching the Ventus S1 evo 3, an Ultra-High Performance tyre for passenger cars and SUVs, on Europe’s roads in early 2019.
A completely new development, Hankook says the Ventus S1 evo 3 has been produced using a new generation of innovative materials with the company’s compounding experts optimising the driving characteristics of the Ventus S1 evo 3 on wet and dry roads by using high-performance natural resins in the tread compound. This, Hankook says, not only increases the grip level at the peak of performance output, but means the tyre also remains at this grip level across a significantly larger range of temperatures.
A high-grip full-silica tread compound and a special mixing technology for a better distribution of polymers and filler material are used in the tread compound resulting in a clear improvement in brake performance in the wet as well as in reducing rolling resistance. A new type of compound for the tyre’s side wall also contributes to this reduction, further lowering the rolling resistance of the Ventus S1 evo 3.
The companys says a new 0-degree cap ply made from aramid composite reduces the unwanted growth in rolling circumference at high and very high (300 km/h and more) speeds by up to 60 per cent compared with traditional nylon-based fabrics, giving the Ventus S1 evo 3 better driving stability and a longer life thanks to lower heat generation.
The cap ply also contributes to an improvement in cornering forces. So-called ‘hyper slants’ in the centre tread bar ribs also help to increase the cornering force by enlarging the contact surface under load. The blocks of highly rigid and wide outer ribs of the asymmetric tread have been reinforced with additional connecting bridges.
The development for the Ventus S1 evo 3 was undertaken in the tyre maker’s European development centre in Hanover, which is part of the global Hankook Tire research network. Production will take place primarily in the company’s production facility in Rácalmás, Hungary. The S1 evo 3 will also be available at market launch in an adapted version for SUVs with a two-ply rayon carcass.
Hankook says a number of versions have already received original equipment approval from German car makers for their latest models. The new Hankook flagship will initially be launched across the entire European market from early 2019. The initial line-up will include over 72 dimensions ranging in size from 17 to 22 inches in the 50 to 25 series, with tread widths ranging from 205 to 315 mm.
