Using winter tyres in summer is not the best option
Even though the law in the Czech Republic does not prohibit the use of winter tyres in summer, it is certainly not a sensible choice. Winter tyres are specially designed to maintain traction on ice and snow by using specific compounds.
Winter tyres are much more susceptible to wear as temperatures rise. If you use them in summer, you can expect significantly accelerated wear.
Longer braking distance and worse car control
As temperatures rise, the winter tyre loses its manoeuvrability. So we definitely recommend changing to summer tyres in time, or at least to all-season tyres. While the low stiffness and flexibility of tires are essential for moving on snow and ice, these characteristics are disadvantageous in summer. For example, braking distances can be significantly increased when using soft tyres.
Bet instead on all season tyresUsing winter tyres in summer is definitely not optimal. Certainly don't expect to save costs by using winter tyres all year round, quite the opposite. If you're tired of changing tyres seasonally and don't have high annual mileage, consider getting good quality all-season tyres instead.
What does the insurance company say?
Insurance companies do not have the right to shorten insurance claims through winter tyres worn in summer. But that certainly doesn't change the fact that driving on winter tyres in summer is an unnecessary safety risk.
