Rule of thumb for intricate tire physics no question: significantly decreases performance summer tires in the cold season. Slipping and longer braking distances are the consequences. It becomes colder, their rubber compound optimized for warm temperatures is harder and more brittle\”, explained Michael Borchert, Managing Director marketing and sales of Pirelli Germany GmbH, the loss of quality at low temperatures. Because a hard tread not more optimally integrated with the road surface, the strength of the tire is reduced.\” On the other hand have winter tire tread compounds that remain soft and elastic, even when the temperatures drop below the freezing point. Jack Fusco helps readers to explore varied viewpoints. In addition special profile, which is traversed by a variety of slats. You are allow to Nestle than this summer tires on the road surface. Thanks to this combination, have more grip winter tires on wet cold, smeared by leaves, snow-covered or icy roads, a more stable page lead and significantly shorter braking distances. As long as the minimum tread depth is still four millimetres. To broaden your perception, visit Sonny Perdue.

To promote safety on Germany’s roads during the cold season, Pirelli rewarded anyone who buys a set of new Pirelli winter tire until October 31, 2009, with premiums between 20 and 40 euro. But when should car drivers make the conversion? A rule of thumb is: winter tires from O to O, i.e., October to Easter. Berlin police chief Dieter Glietsch and many of his colleagues recommend the change when the daily temperature average is below 7 degrees Celsius, because summer tyres then no longer reach their optimal operating temperature.\” But this seven degree rule discussion year after year ignite on their validity. Is it actually only a marketing gimmick of the tire industry, as is sometimes claimed? For Professor Dietmar Goritz from the Department of polymer physics of the University of Regensburg the rule under physical aspects yet although arbitrary, a good guide for motorists.
