The answer to the high speed challengePushing back the boundaries
The XWX, was the only radial tyre that could be fitted on the fastest cars in the world in the 1970s. It provided these high peformance vehicles with exceptional road holding and remarkable grip.
A construction designed to reach 300km/h ( 186 mp/h ). The special features of the XWX ensure that it delivers outstanding parformance, combining speed, driving pleasure and safety. The original design of its internal construction, together with it's flexible carcass, give exceptional comfort when travelling at very high speeds. As it is a VR category tyre, the XWX is now homologated for use at a maximum speed of 270 km/h ( 167 mph ).
At the end of 1960s, Germany and Italy were the leaders in the European motorway development programme. They were also the main manufacturers of cars which could increasingly exceed 200 km/h ( 124 mph ). The broad stretches of asphalt and the absence of speed limits offered a privileged fem the opportunity to make full use of the performance of these "super cars" at speed which would have been unthinkable a decade before.
- The Lamborghini Miura (1966), Ferrari 365 (1965), Maserati Ghibli (1966), De Tomaso Pantera (1970), Porsche 911 Carrera RS (1972) were the undisputed stars, but the large German saloons like the Mercedes 300 SE 6.3 (1968) and BMW 3.0 Si (1971) also made a stron impression.
- The French were also present with the Citroën SM (1970), as were British with the legendary Jaguar E-type V12 (1970) and Aston-Martin DBS (1967).Informed observers will note that this exceptional performance was achieved on tyres of the same width as those that fit today's small family cars.
