Winter TyresCzechia Winter Tyres 2026: 1 Nov-31 Mar, 4 mm Tread
Czechia requires winter tyres from 1 November to 31 March when snow, ice or frost lies on the road, or where the Zimní výbava sign stands. Minimum tread is 4 mm for cars up to 3.5 tonnes.
Czechia’s winter rule has dates and a condition. From 1 November to 31 March, winter tyres with at least 4 mm of tread are required once snow, ice or frost lies on the road — or wherever the winter-equipment sign stands.
Two triggers, one season
Section 40a of Act 361/2000 Sb. sets the window at “od 1. listopadu do 31. března” and then names what switches the obligation on inside it: the road carrying “souvislá vrstva sněhu, led nebo námraza” — a connected layer of snow, ice or frost — or weather that makes such a layer likely during your journey. A second trigger is simpler still: the blue “Zimní výbava” sign, which imposes the requirement regardless of what the surface looks like.
So on a clear, dry December afternoon on an unsigned road, summer tyres are legal. Cross a ridge into snow, or pass that blue panel, and they are not. The sign tends to appear exactly where you would expect trouble: the approaches to hills, the border passes, and the D-roads that climb.
The 4 mm Number Is the One That Catches People
The Czech tread requirement is not the familiar European 1.6 mm. Section 40a specifies “nejméně 4 mm” for vehicles with a maximum weight up to 3,500 kg, and “nejméně 6 mm” above that. A tyre that would pass a roadside check in France or Germany can therefore fail in Czechia while wearing exactly the same amount of rubber.
| Season | 1 November – 31 March |
| Trigger | Snow, ice or frost present or expected, or the Zimní výbava sign |
| Tread, up to 3.5 t | 4 mm minimum |
| Tread, over 3.5 t | 6 mm minimum |
| Accepted marking | M+S or 3PMSF |
| Studs | Prohibited |
| Fine | Up to CZK 1,500 on the spot; CZK 2,000–5,000 administrative |
Studded Tyres
Czechia prohibits studs outright. There is no seasonal exemption and none for foreign plates, so studded tyres fitted for a Baltic or Scandinavian leg have to come off before you enter.
All-Season Tyres
All-season tyres marked M+S or 3PMSF are accepted — but the 4 mm rule still applies to them, and an all-season set worn to 3 mm is non-compliant even though it looks serviceable.

Check Tyre RequirementsWhat Most Guides Don’t Tell You
“Or can be expected” is doing a lot of work
The wording covers conditions you might meet later in the drive, not only the surface under your wheels right now. Set off from a dry Prague in the morning towards the Krkonoše in a forecast snowfall and the obligation travels with you. Czech police read it that way, and it is the part of the rule most visitors never notice.
The sign outranks the weather
Where Zimní výbava is posted, there is no argument to have about whether the road was snowy. The sign is the trigger. Learn what it looks like — a blue square with a tyre and snowflake — because it is the cheapest piece of knowledge on this page.
Insurance follows compliance
Driving on summer tyres in the conditions section 40a describes gives an insurer a contributory-negligence argument after a crash, even when the other driver caused it. The on-the-spot fine is modest; the reduced payout is not.
Tread depth reality
At the 4 mm line a winter tyre still has usable sipe depth. Below it, snow traction falls away quickly, which is precisely why the Czech legislator set the bar higher than the general 1.6 mm. Measure before the trip rather than at the border.

At least 4 mm for vehicles up to 3,500 kg and at least 6 mm above that, under section 40a of Act 361/2000 Sb. The 1.6 mm figure is the year-round general minimum and is not enough in winter conditions.
