Winter TyresWinter Tyres in South Korea: No Law — but Gangwon Gets Buried
It depends on more factors than you might expect in South Korea. Marking changes, enforcement patterns and rental car implications all play a role. Full details below.
There is no legal obligation to use winter tyres in South Korea. However, a tread depth of at least 3.0 mm is recommended for safety.
No rule nationwide — but the north-east buries under snow
South Korea has no nationwide winter-tyre law, and around Seoul and the milder south all-season tyres cope with most of the winter. But the mountainous north-east — Gangwon Province, home to the ski resorts and the 2018 Winter Olympics sites — gets heavy, reliable snow, and there winter tyres or snow chains are strongly advised, with chains sometimes required on steep or mountain roads. Rental agencies in snowy regions fit winter tyres in season. So the honest answer depends on where you drive: staying in the cities you’ll be fine on normal tyres, but heading to Pyeongchang or the Gangwon ski country in deep winter, fit winter tyres or carry chains.

How Strictly Is This Enforced?
Enforcement varies by region. Mountain areas and busy transit corridors see the most checks. Rental agencies in South Korea usually handle tyre changes, but always verify before driving away.
All-Season Tyres: Good Enough?
South Korea accepts all-season tyres as a winter alternative, provided they carry the correct marking. They work well for mild winters and mixed driving.
However, dedicated winter tyres outperform all-seasons below 7 degrees Celsius. If your route includes mountain passes or areas with regular snowfall, a dedicated set is the safer choice.
Studded Tyres
Studded tyres are permitted in South Korea only during specific months and on certain road types. Check the local rules carefully before fitting studs, especially when crossing borders from a country where they are freely allowed.
Insurance Implications
Although winter tyres are not legally mandated in South Korea, some insurers reduce payouts if an accident occurs in winter conditions with summer tyres fitted. Check your policy wording.
Tread Depth Reality
The legal minimum in South Korea is 1.6 mm, but tyre performance drops sharply below 3.0 mm. Replacing tyres before they hit the legal limit gives you a meaningful safety margin on wet or icy roads.
