Roadtec Z8 Interact The innovative tire for the sport tourer and ideal companion at long distances; whether on country roads, on the highway or on ambitious mountain routes. The new Z8 touring sports tire offers unprecedented performance and safety from the first kilometer, fully loaded or in difficult weather conditions. Its tread grooves, inspired by the Greek Pi and Interact technology with 5-zone tension, are the result of numerous series of tests in which various tensions have been tested in the steel belt of the tire and finally optimally integrated. The result: maximum efficiency in all driving situations both in dry conditions (stability) and in wet conditions (drainage), at the same time increasing tire life. Therefore, the Z8 covers the profile of the requirements of ambitious cycle tourists, who also love to make it a little sportier and faster. Roadtec Z8 is the guarantee for maximum stability when driving on the straight, for high mileage and at the same time a loyal and manageable partner in curves.
