Typhoons, Not Snow, Test Tyres in Taiwan for 2026-27

Taiwan’s tyre concerns run to typhoon season, not winter — there’s no seasonal tyre mandate on the books at all. Studded tyres are restricted rather than freely permitted. The legal tread minimum is 1.6mm, the same figure used across most tropical entries in this guide.

Taiwan’s typhoon-season downpours make tread depth a real safety issue, not a formality — keep an eye on it.

Tyre Law Summary for Taiwan

Winter Tyre Rules in Taiwan

Taiwan has no legal requirement for winter tyres. However, if you drive in areas that experience cold temperatures (below 7°C), winter or all-season tyres provide measurably better grip than summer tyres. Summer rubber hardens in cold weather and loses traction significantly.

Minimum Tread Depth in Taiwan

In Taiwan, the legal minimum tyre tread depth is 1.6 mm, measured across the central three-quarters of the tread width around the full circumference.

For Taiwan’s roads, the practical replacement threshold is 3.0 mm — well above the legal minimum. The difference in wet braking at 80 km/h:

How to check in Taiwan: 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 Taiwan

Studded tyres are restricted in Taiwan. Restrictions typically cover the period when studs may be used, the number and size of studs, and sometimes specific road types where they are banned. Verify the current rules for your route.

All-Season Tyres in Taiwan

All-season tyres are a legal option in Taiwan 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 Taiwan

Non-compliant tyres in Taiwan can result in fines during police checks. The financial risk extends beyond the fine itself — if you are involved in a collision with illegal tyres, you may be found at fault regardless of other circumstances.

Tyre Considerations for Taiwan’s Conditions

With seasonal climate with monsoons, Taiwan 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 Taiwan

Taiwan 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.

How Taiwan’s Tyre Laws Compare to Neighbours

Tyre requirements change at borders. Here is what to expect near Taiwan:

• North Korea: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• Mongolia: Winter tyres mandatory (October - April). Tread: 1.6 mm. Studded: allowed.
• South Korea: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• China: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.

Note that Mongolia has stricter winter tyre rules than Taiwan. If you are crossing the border in winter, you may need to fit winter tyres even though they are not required at your starting point.
