One of the well known European tuners, Franz Engstler, chooses his tyres from the recent Zeta series, released by the Italian manufacturer, Marangoni. Created in the middle of the 20th century this rubber company has learnt very rapidly how to break through the European, US and Latin America markets. Except from the traditional benefits that Marangoni tyres offer, they seem to also have some well kept secrets. In the Rovereto and Feltre factories, among the most modern and sophisticated in the world, the Italian engineers have quickly understood that the key to the future lies in the creation of ecological and highly recyclable tyres. Marangoni is indeed among the most respected pioneers on the international market, thanks to its technological achievements. The tyre is made of 75% recyclable raw material, played a turning point in this company's evolution that has always followed the "intelligent technology" concept.
