Find Tyres for You
When to change to winter tyres?
In this section we advise how to greet the new season on the road properly planning the replacement tyres. According to tyre manufacturers’ recommendations there is a principle of the minimum of seven degrees. If the temperature is lower during the day, you should install winter tyres as soon as you can. Some drivers believe that the principle of the seven degrees is a marketing ploy and winter tyres work best at temperatures close to zero. Therefore it would wait with their replacement until there will be a winter. Who is right?
Seven degrees is the contractual limit but not unfounded. Already the first frosts should be a warning to us. Once in the morning and the evening starts to make a cold, you might want to call the shop to make an appointment to fit winter tyres. In addition, we can panic when the road will be covered by the first surface of the snow. Winter tyres ensure greater mobility in all winter conditions because it is designed and dedicated differently than a summer tyre. It has good drainage in winter temperatures, and retain the grip on slippery surfaces and snowy. Do not wait for the first frost or snowfall, because then the vulcanization services will queue and driving on slippery roads less safe. It is worth thinking about winter tyres as a good investment because with proper use and storage can serve us for several seasons and in dicey situations on the road prove invaluable support.
Summer and winter tyres differ in tread patterns and have different configurations of mixtures. The tread of winter tyres is more nicked in relation to the summer one. Larger number of notches makes the rubber is more flexible, more susceptible to deflections as winter temperatures and tyre performance. The cuts on the tread is wider than in the case of summer tyres , create wide grooves, which are more prone to self-cleaning tread pattern. The composition of winter tyres is significantly different from summer tyres. Winter tyres with high silica content being flexible and does not harden in cold conditions . Soft tyre provides high grip and traction, tyre hardened does not provide anything beyond an uncontrolled skid. In many tests it has been shown that summer tyres are about 30 percent longer braking distance than winter ones. Braking distance determines the extent of our security. If we want to significantly raise, just use winter tyres.
