How to choose winter tyres: EU label, the law and the price of a set

What the law says

Under § 40a of Act No. 361/2000 Coll., cars and other vehicles up to 3.5 t must have winter tyres on all wheels from 1 November to 31 March whenever the road has a continuous layer of snow, ice or frost, or the weather suggests it may have one during the trip.

Winter tyres must have a main tread depth of at least 4 mm, at least 6 mm on vehicles over 3.5 t. The only exception is a spare wheel used to reach a garage after a puncture.

What to look at

The tyre label under EU Regulation 2020/740 has applied since May 2021 and carries a QR code into the EU EPREL database with the data of every model and size.

• Rolling resistance (class A to E): affects fuel use or an EV's range; A is the most efficient.
• Wet grip (class A to E): braking distance on wet asphalt; A stops shortest. In winter this is the most important letter on the label.
• Noise (dB and class A to C): rolling noise outside the car; A is the quietest.
• Three-peak mountain snowflake (3PMSF): the tyre is approved for severe snow conditions.
• Ice symbol: a tyre for very cold, icy roads, typically Nordic; ordinary Czech roads do not need it.
• Size and indexes, e.g. 205/55 R16 91 H: width in mm, height-to-width ratio in %, rim diameter in inches, load and speed index. The right values for your car are in its registration papers.
• Production date: four digits on the sidewall (week and year), e.g. 3825 is week 38 of 2025.

Examples by size

Price history

Demand for winter tyres grows from October, most with the first snow; buying earlier gives a wider choice of sizes in stock.

Common mistakes

• Comparing the price of one tyre without shipping; tyre shipping is often charged per tyre or per set and varies.
• Buying another size or a lower load index than the registration papers state.
• Driving on winter tyres below 4 mm; the law then no longer counts them as winter equipment.
• Mixing different models or wear on one car.
• Buying 'new' tyres several years old; check the production date on the sidewall.
• Forgetting the cost of fitting and balancing.
