As many as three models have arrived on the market SportContact 7 tires society Continental with different specifications: the design of the profile adapts to dry and wet roads, the design of the profile, adjusted to the size, provides driving pleasure with each vehicle, rubber compound Black Chili however, with its composition it enables precise adhesion of the asymmetrical profile.
Continental has thus developed a sports tire that sets new standards for tire performance and creates a high level of confidence in the driving characteristics of a new tire. "In our development, we have focused on creating the best sporty summer tire on the market, suitable for all vehicle classes," he said prof. dr. Burkhard Wies, Head of Research and Development of Passenger Car Tires in the Company 's Global Tire Replacement Market Continental .
"Thus, we wanted to achieve significantly better driving characteristics on dry and wet roads and on the racetrack, and we also wanted to ensure a higher number of kilometers, which is 17% better than its predecessor. "We also contribute to the sustainability aspect with very good fuel efficiency with the EU label" C "."
With an asymmetrical, flexible tread design, a new tire can be made SportContact 7 adapts to dry and wet roads. Thus, its driving characteristics remain at a consistently high, safe level - even at higher speeds. "You can also load the tire by exposing it to more difficult conditions," he says Wies.
"The new, flexible profile ensures safety and confident driving in such situations, together with very precise cornering stability on wet and dry roads." This is made possible by the design of the profile: when driving straight "Tire print" finishes at the site of the highest water outflow in the profile for excellent grip when braking, accelerating and cornering on wet roads. When turning on dry asphalt "Imprint" moves to the outer shoulder, which is designed to transmit the highest forces for stable conductivity. New ones provide additional stability "Blocking elements" in the outer shoulder, which allow only limited movement of the profile and thus high driving stability.
Conventional sports tires respond differently to different concepts and vehicle weights - depending on the weight, size and engine of the car. "Our new SportContact 7 is therefore the first product in the high-performance tire segment to suit every vehicle type." explains Wies. Heavy vehicles require different tire solutions than light passenger cars. Therefore, the specifications SportContact 7 tires adapted to each class of vehicle.
“To this end, we have developed new technologies, including for races that are used according to the size of the tires, so that the driving characteristics typical of the SportContact line are maintained in each vehicle. This means that we have a customized design for different classes of vehicles. We can also adapt the stability of the sidewall, grip in certain load situations, as well as high-speed performance, handling and carcass design to each class of vehicle. ” he added.
The third technological component of the new tire SportContact 7 is a rubber compound Black Chili, which is precisely adapted to the design of the profile. This soft compound fits the very hard, low-profile design of the tires and provides extremely good driving characteristics while significantly increasing mileage.
That’s why engineers and tire chemists at the company had to Continental reconcile different conflicting goals. The result of their collaboration is an unusual compound technology that, together with the profile design, allows for a significant improvement in driving characteristics. Compared to its popular predecessor Continental's internal tests show amazing results: mileage has increased by 17 percent, performance on the racetrack increased by 10 percent, braking distance on wet roads decreased by 8 percent, and when braking on dry roads, there is a new tire SportContact 6 percent better. The novelty also affects better handling on wet and dry roads and traction (245/30 R 20 tire size test).
