Winter Tyres
In Latvia, cars and vans up to 3.5 t must be fitted with winter tyres from 1 December to 1 March, and they must then carry the 3PMSF symbol and have at least 4 mm of tread. This section covers studded and friction tyres – the choice depends on how often you drive on ice and uncleared roads. Read the guide
What the rules say
- Period. Under paragraph 219 of the Road Traffic Regulations, cars, vans and buses with a gross weight of up to 3.5 t must have tyres designed for winter conditions from 1 December to 1 March.
- Marking. Cabinet Regulation No. 295 on roadworthiness inspections requires winter tyres in this period to carry the mountain-and-snowflake symbol (3PMSF). A tyre marked only M+S does not meet the requirement.
- Tread. During the mandatory winter period, winter tyres must have at least 4 mm of tread; the rest of the year the minimum is 1.6 mm.
- Studs. Driving on studded tyres is prohibited from 1 May to 1 October, and studded and non-studded tyres must not be mixed on one vehicle.

Studded or friction
The choice comes down to where you drive most. If your daily route includes rural roads that are not cleared every morning and ice is the main risk, choose studded tyres. If you mostly drive on cleared streets and main roads, friction tyres are quieter and not tied to the stud season.
Checking your set before the season
- Sidewall symbol – look for the mountain with a snowflake (3PMSF), not just M+S. The difference is explained in our article on the 3PMSF marking.
- Tread – measure the depth in several places across the tyre: if it will be below 4 mm by 1 December, replace the set now.
- Matching tyres – tyres on the same axle must be the same size and make, with the same tread pattern.
When to fit them
The mandatory period is shorter than the real winter: the first frosts and icy mornings can arrive in October, and cold snaps often return after 1 March. Plan the change around the forecast and your own driving rather than the calendar alone. For a seasonal calendar and practical tips, see when to change tyres in Latvia.
