In April, a survey was conducted in Slovakia and the Czech Republic on the quality of automobile tires. A total of 1,635 vehicles were able to measure tread depth, of which 723 were in the Czech Republic and 912 in the Czech Republic.

The field survey was aimed at finding out about the depth of the tread. state of the tires of Slovak and Czech vehicles. The survey was conducted in April in five cities in Slovakia (Považská Bystrica, Bratislava, Banská Bystrica, Kosice, Prešov), where she was the expert guarantor of the BECEP – Department of Road Safety of the Ministry of Transport and the construction of the Slovak Republic. In the Czech Republic, it was carried out under the supervision of BESIP, the Ministry of Transport of the Czech Republic, in ten cities (Hradec Králové, Pardubice, Prague, Liberec, Ústí nad Labem, Plzeň, České Budějovice, Brno, Olomouc and Ostrava ).

According to the survey, Slovakia has obtained an unflattering bonus with regard to the number of tires having a tread depth of less than 1.6 millimeters (mm) for summer tires . An investigation in Slovakia revealed ten of these vehicles. Only two were registered in the Czech Republic.

"The depth of the tread is the basis of a safe ride, and on used tires at 1.6 mm or less, there are more and more risks, so we do not recommend to the driver to expect a minimum legal limit of 1.6 mm or less, "commented Juraj Ižvolt of the company Continental Barum sro

During the winter of this year, the most used tires in their vehicles were drivers in the Banskobystrický region.Most 10% of them ride with winter tires of a thickness of less than 3 mm, which corresponds to the depth of minimum sculpture for winter tires in RS.The least of these vehicles were measured in the Bratislava region, just over 1%

In total, 25 vehicles with a depth less than 3 mm were registered in Slovakia, accounting for 11% of all Slovak vehicles equipped with In the neighboring Czech Republic, the situation is similar. The value of 4 mm or less (which is the minimum tread depth for winter tires in the Czech Republic) was 15% of tires measured with winter tires.

The survey also shows that drivers are accustomed to winter tires less than 3 mm. but their characteristics are significantly different from the new summer tires. "The average braking distance of the winter tire with a dry run of 3 mm on the dry road is 39.3 meters and wet up to 87.9 meters. in wet conditions, the braking distance of worn-out winter tires is more than 20 meters compared to new tires and is about 10 meters longer than worn-out tires, "explains Ižvolt [19659010]increased consumption and noise, so drivers should take it seriously

tire wear rates of the front and rear axles were also examined, and the results showed that It tends to be about the same, but there was only a very small difference: in Slovakia and the Czech Republic, the sample used was 48% of the total. front axle, rear 52% The largest measured difference in depth d The sculpture between the front and rear tires was 9 mm in Slovakia. In the Czech Republic a little less, and less than 6 mm
