Andorra Asks Only One Thing of Tyres: 1.6mm Tread, 2026-27

Andorra keeps tyre rules straightforward. Winter tyres are not legally required, but minimum tread depth of 1.6 mm applies all year. Most rental companies expect M+S marking or dedicated winter tyres in colder months, so check your booking terms. Using summer tyres below 7°C risks both safety and insurance claims.

Whether you are driving to Andorra on a cross-border trip or renting a car locally, compliance takes minutes; contesting a fine abroad takes weeks.

Tyre Law Summary for Andorra

Winter Tyre Rules in Andorra

Winter tyres are not mandated in Andorra, but they are still a smart choice if temperatures regularly drop below 7°C. At that point summer tyre rubber becomes too hard for effective braking, and the stopping distance increases dramatically.

Minimum Tread Depth in Andorra

Andorra sets the legal tread depth minimum at 1.6 mm. Inspectors measure across the central three-quarters of the tread surface.

Safety organisations recommend that drivers in Andorra replace tyres at 3.0 mm rather than running them down to the legal limit. The difference in wet braking at 80 km/h:

Checking tread depth: most tyres sold in Andorra have wear indicators (TWI) moulded into the grooves. When the tread surface is level with these bars, you have reached 1.6 mm and the tyre must be replaced.

Studded Tyres in Andorra

Studded tyre regulations in Andorra are not clearly defined. Check with local authorities or your rental company before fitting studded tyres.

All-Season Tyres in Andorra

All-season tyres are a legal option in Andorra provided they carry the M+S marking. They are a popular choice for drivers who want year-round convenience without maintaining two sets of tyres.

Penalties for Tyre Violations in Andorra

Driving with illegal tyres in Andorra risks fines and, more critically, insurance problems. If you have an accident and your tyres do not meet the legal standard, your insurer may reduce or refuse your claim entirely.

Tyre Considerations for Andorra’s Conditions

With Mediterranean climate with hot summers, Andorra presents moderate tyre challenges:

• Wet autumn and winter roads demand good tread — do not push tyres to the 1.6 mm legal limit before replacing them
• Summer heat increases pressure; winter cold decreases it. Check monthly
• If you mainly drive in urban areas with mild winters, all-season tyres are practical. For mountain routes or frequent winter driving, dedicated seasonal tyres are the safer option

Road Conditions and Tyre Wear in Andorra

Andorra has a well-maintained road network. Tyre wear tends to be predictable and even on main roads. Urban stop-and-go traffic causes shoulder wear, while longer highway stretches wear the centre. Regular rotation (every 8,000–10,000 km) keeps wear even.
