Continental strongly recommends using the appropriate tyre for each season. That means driving on summer tyres during the warmer months and on winter tyres during the colder seasons. Such tyres feature different rubber compounds, tread grooves and widths to suit different weather conditions. The marked differences between summer and winter tyres provide the best balance of safety and economy year-round.
All-season tyres cannot provide optimal performance year-round under all conditions.
The rule of thumb: summer tyres should be fitted to your car for the period between Easter and October.
