Mongolia 2026-27: Winter Tyres From October to April

Mongolia’s winter tyre mandate covers October through April — seven months, one of the longest windows anywhere — and all-season tyres do not satisfy it: the requirement is dedicated winter rubber. Studded tyres are allowed, which is the sensible trade here rather than an indulgence.

The reason the rule is strict is the geography behind it. Beyond Ulaanbaatar much of the network is unsealed, distances between settlements are long, and a recovery can be hours away in temperatures that punish waiting. Tyre condition is a safety question here long before it is a compliance one.

Tyre Law Summary for Mongolia

Winter Tyre Requirements in Mongolia

Mongolia has a mandatory winter tyre requirement covering the period October - April.

During this period, all passenger vehicles on Mongolia’s roads must have tyres that meet the winter standard. Driving without them risks fines and insurance complications in an accident.

Practical advice for Mongolia:

• Fit winter tyres before the mandate starts — garages in Mongolia get fully booked in the final weeks
• Minimum tread depth of 1.6 mm applies, but 3.0 mm is the practical minimum for winter grip
• Snow chains may be required on specific mountain routes regardless of tyre type

Minimum Tread Depth in Mongolia

Mongolia 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 Mongolia replace tyres at 3.0 mm rather than running them down to the legal limit. The difference in wet braking at 80 km/h:

How to check in Mongolia: use a tread depth gauge from any automotive shop, or look for the built-in tread wear indicators (TWI) — small raised bars in the grooves that become flush with the surface at 1.6 mm.

Studded Tyres in Mongolia

Studded tyres are allowed in Mongolia. If you drive in areas of Mongolia where ice is common, studded tyres offer the best traction available. On dry roads, however, they increase braking distance and wear faster. Many drivers in Mongolia use friction winter tyres as a compromise.

All-Season Tyres in Mongolia

Mongolia does not accept all-season tyres during the winter tyre period. Dedicated winter tyres meeting the required marking standard are mandatory. All-season tyres may be used outside the regulated period.

Penalties for Tyre Violations in Mongolia

Driving with illegal tyres in Mongolia 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 Choice for Mongolia’s Climate

Mongolia has a sharply continental climate: hot, dry summers and a long, severe winter. Tyres are asked to do two completely different jobs seven months apart.

• Summer (roughly May to September): heat raises pressures and accelerates wear, and unsealed roads chew sidewalls. Check pressures cold each month and inspect for cuts, cracks and bulges
• October to April: dedicated winter tyres are compulsory, studs optional, and an all-season set does not substitute. Below 4 mm a winter tyre gives up most of its ice advantage
• Two sets, not one: the swap is not a preference here, it is how the year is structured

Road Conditions and Tyre Wear in Mongolia

Sealed road is the exception once you leave the main corridors. Ulaanbaatar and the routes between the larger centres are paved; much of the rest is gravel, sand or simply a set of tracks across the steppe, and that is where tyres are lost — to cuts and sidewall damage rather than to gradual wear.

Carry a full-size spare, a compressor and a repair kit; drop pressure slightly on soft sand and reinflate on hard surface; rotate every 8,000–10,000 km to keep wear even on the sealed sections.

How Mongolia’s Tyre Laws Compare to Neighbours

Planning a cross-border trip from Mongolia? Here is how neighbouring countries differ:

• North Korea: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• Taiwan: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• South Korea: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• China: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.

North Korea and Taiwan do not require winter tyres, so if you are leaving Mongolia you may be carrying winter tyres unnecessarily — but they still improve safety in cold weather.
