Since June of this year, the Porsche Cayenne has been supplied with Hankook’s Ventus S1 evo 3 SUV tires in size 285/40 ZR 21 (109Y) XL at the front and 315/35 ZR 21 (111Y) XL at the rear, as well as in a few other sizes. The version fitted to the sportscar has been tweaked bespoke for this application.
“Porsche develops particularly powerful sportscars with a high utility value. This makes tire development very complex,” said Han-Jun Kim, president of Hankook Tire Europe. “We are therefore very pleased with this original equipment fitment as it demonstrates the performance of our products.”
“Due to the vehicle load in combination with sporty driveability, low rolling resistance and high load capacity, it was very challenging to develop the tire design for the Porsche Cayenne,” explained Klaus Krause, head of the European Research and Development Centre at Hankook Tire. “The new Ventus S1 evo 3 SUV meets these requirements closely in both wet and dry conditions.”
Based on motorsport-tested tire technology from DTM, the new ultra-high performance tire is said to offer high steering precision and ‘sporty’ handling.
The tread features a new generation of materials based on high-performance natural resins. This not only increases the grip level in the peak of the power output, but the tire also continues to deliver this high level of grip over a much wider temperature range, giving it a very wide limit. Special nylon materials applied in the so-called ‘bead-packing’ process in the sidewall ensure very high driving stability, even under load. The cap ply hybrid aramid material over the steel cord belts, in combination with the two-layer rayon carcass construction, ensure good resistance and durability.
