Comoros' Whole Tyre Law: 1.6mm, No Season, 2026-27

The Comoros archipelago has no winter tyre requirement—the warm climate makes it unnecessary. A single rule applies year-round: maintain 1.6 mm minimum tread depth. Summer or all-season tyres handle the tropical weather, though the December-to-April monsoon season demands tyres with deep treads for standing water and torrential downpours.

For anyone driving in Comoros, from residents to tourists on safari, these rules are cheap to follow and expensive to ignore.

Tyre Law Summary for Comoros

Tyre Requirements in Comoros

Forget winter tyres — Comoros does not need them. Temperatures stay high enough year-round that summer tyre compounds perform well in all months.

The real tyre issue in Comoros is rain. When heavy downpours hit, worn tyres with minimal tread lose grip almost completely. Keep tread well above the 1.6 mm legal minimum, and choose tyres designed for wet grip over dry performance.

Minimum Tread Depth in Comoros

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

Heat accelerates tyre degradation in Comoros. UV exposure and high pavement temperatures cause rubber compounds to harden faster, so a tyre that looks fine may already have reduced grip. Check tyre manufacture date — replace tyres older than 5 years regardless of tread remaining.

Penalties for Tyre Violations in Comoros

Driving with illegal tyres in Comoros 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.

Choosing Tyres for Comoros

With diverse terrain from coastal to highland, Comoros does not require seasonal tyre changes. The focus should be:

• Wet traction: frequent rain and standing water in Comoros make hydroplaning the biggest tyre risk
• Heat resistance: road surface temperatures can exceed 60°C, softening rubber and increasing wear
• Age: UV exposure in Comoros degrades tyre compounds faster — replace at 4-5 years
• Pressure: check monthly; heat causes pressure to rise, affecting contact patch and wear pattern

Road Conditions and Tyre Wear in Comoros

Roads in Comoros range from well-surfaced highways near Moroni to rough, unpaved tracks in rural areas. This variety means tyre condition matters even more than in countries with uniformly smooth roads.

• Potholes and broken surfaces cause sidewall damage — inspect tyres after rough sections
• Consider tyres with reinforced sidewalls for extended travel outside Comoros’s main cities
• Carry a repair kit and compressor alongside your spare tyre
