Across China's Climate Extremes, One Tyre Rule, 2026-27

Across China’s climate extremes — subtropical south, sub-zero north — the traffic law still sets no nationwide winter tyre mandate. The tread floor enforced everywhere is 1.6mm, with 3mm recommended for wet-weather safety. Studded tyres sit in a middle category — restricted, not banned — so check regional rules before fitting a set.

Driving in China on a foreign or international permit is complicated enough without a tyre fine on top — get the basics right first.

Tyre Law Summary for China

Winter Tyre Rules in China

China 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 China

The minimum tread depth enforced in China is 1.6 mm. This is measured across the central three-quarters of the tread, all the way around the tyre.

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

At China’s motorway speeds of 120 km/h, tyre condition is not just a legal issue — it is a survival issue. The energy a tyre must dissipate during emergency braking increases with the square of speed, so worn treads at motorway speed are far more dangerous than in town.

Studded Tyres in China

Studded tyres are restricted in China. There may be seasonal windows, regional rules, or maximum stud specifications. Check local regulations before fitting studded tyres, especially if you are driving across regional borders.

All-Season Tyres in China

All-season tyres with the M+S marking are accepted in China. For drivers who prefer not to switch tyres seasonally, they offer a practical middle ground — adequate in mild winters and acceptable in summer heat, though not optimal in either extreme.

Penalties for Tyre Violations in China

Tyre violations in China carry fines and may affect your licence. For context on enforcement severity: a seatbelt violation costs CNY 50-200 (approx. EUR 6-25) + 2 points, so expect tyre offences to be taken at least as seriously.

Tyre Considerations for China’s Conditions

With seasonal climate with monsoons, China 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 China

Road surfaces in China are generally good quality, with well-surfaced motorways and maintained secondary roads. Sustained motorway driving at 120 km/h increases centre-tread wear. Rotate tyres every 8,000–10,000 km for even wear across all four positions.

How China’s Tyre Laws Compare to Neighbours

If you are driving across borders from China, tyre regulations may change at each crossing:

• Japan: Winter tyres situational (Prefectural regulations; Hokkaido, Tohoku require winter tyres in winter). Tread: 1.6 mm. Studded: restricted.
• South Korea: Winter tyres not required. Tread: 1.6 mm. Studded: restricted.
• Vietnam: Winter tyres not required. Tread: 1.6 mm. Studded: not applicable.
• Thailand: Winter tyres not required. Tread: 1.6 mm. Studded: not applicable.
