Czech laws define the obligation of winter tires from November 1, but only under certain conditions. If summer has dragged on and November afternoons still bring temperatures around fifteen degrees, there is no point in changing shoes. You would actually damage your winter tires unnecessarily. On the other hand, it doesn’t pay to procrastinate, with the first snow the tire repair shops will be overcrowded and you will have a hard time looking for a free appointment. And why should you change your shoes regularly? There are many reasons, first and foremost safety.

When to switch to winter tires

Let’s start with a little recap. With us, the obligation of winter tires is defined as follows: According to §40a of Act 361/2000 Coll. drivers are required to use winter tires between November 1 and March 31 if:

  1. There is a continuous layer of snow, ice or frost on the road.
  2. Due to the weather conditions, it can be assumed that there may be a continuous layer of snow, ice or frost on the road during driving.

Why not drive on summer tires in winter

Summer coats are adapted to better weather and as a rule they work best at temperatures above 7°C. But mainly they are not designed for driving on a continuous layer of snow or ice, and thus do not provide the necessary grip. The driver does not have such support in the driving characteristics, the braking distance of the car increases and the safety of the entire crew is unnecessarily endangered.

Why not drive on winter tires in the summer

It might seem that nothing can happen if you keep your winter clothes even in the summer. But the opposite is true. On the other hand, the winter rubber compound is modified in such a way that it worked ideally in temperatures around zero. If you operate it on sunny days, there is a risk of loss of grip again and the braking distance increases by up to twenty percent. You are unnecessarily destroying your winter coats with such use, it is much better to put them on in time and store them for the next winter.

Let’s also not forget the proper storage of tires. In the off-season, they should remain dry and dark, ideally at a temperature below 15 degrees Celsius.

Minimum tread depth

It is a good idea to check your winter and summer footwear regularly. Above all, the depth of the pattern, i.e. the grooves, which guarantee optimal grip and driving characteristics. You should replace your winter tires before the tread depth drops below 4 millimeters (new ones are usually 7 to 8 mm). The recommended minimum groove depth for summer tires is 3 millimeters. The higher the depth, the better the driving characteristics.

When to buy new tires

In addition to the depth of the tread, it is recommended to monitor other aspects, especially the age of the tires. Generally speaking, you should use one set a maximum of four years. Later, the tire begins to lose its original properties and is also more susceptible to a possible defect.

You can find out the production date simply by using DOT code, which is located on the tire casing. The last four characters of this code indicate the date of manufacture. For example, if the numbers 1523 are there, it means that the tire was manufactured in the 15th week of 2023.

If you are looking for new tires right now, we definitely recommend using internet search engines and advisors. On the Zboží.cz server, you can filter individual sets according to price, but also by the popularity of customers who already have experience with the jackets in question. We wish you a happy hand when choosing!
