Madagascar Tyre Rules 2026: 1.6 mm, No Land Border

Madagascar is an island, which settles the border question before it is asked: there is no land crossing and no point at which the rules change under your wheels. There is also no winter tyre rule, no marking requirement and no stud category.

The tread floor is 1.6 mm in the main grooves, the international reference set out in Council Directive 89/459/EEC. What wears tyres out here is the state of the RN network and the season that wrecks it.

Tyre Law Summary for Madagascar

Cyclone season rewrites the map

From roughly November to April, and most intensely between January and March, tropical cyclones cross the island, usually making landfall on the east coast.

The effect on driving is categorical rather than incremental. Bridges fail, embankments collapse, and stretches of the RN network are not degraded but removed. A route that existed in October may not exist in February, and the authoritative source on any given day is local rather than cartographic.

For a driver that means two things: plan the season, and treat every long leg as one that may have to be abandoned halfway.

The highlands are genuinely cold

Antananarivo sits at about 1,280 metres, and the Ankaratra massif nearby rises above 2,600. In the southern winter — June and July — capital nights fall to single figures and the highest ground records frost.

This produces no rule and no requirement, and it should not. But it does mean tyre pressures drop noticeably on a cold highland morning, and that a driver who packed for the tropics has misjudged the range. Set pressures cold from the door sticker and check them again after a change of altitude.

Laterite is the everyday surface

Away from the sealed RN sections the network is red laterite and sand. Dry, it is fast and deceptively comfortable; wet, it is slick and deeply rutted.

The typical failure here is not worn tread but a sidewall cut from loose rock, and a sidewall cut cannot be repaired at the roadside. A full-size spare, a jack with something solid to stand on, and the habit of rinsing dried clay out of the grooves so cuts and stones are visible cover most of what goes wrong.

No borders, only sea routes

Madagascar shares no land border with anyone. The closest countries are Comoros to the north-west, Mauritius and Réunion to the east, and Mozambique across the channel — all of them by sea or air, and none of them applying a seasonal tyre rule.
