Chad's Only Fixed Tyre Rule Is a 1.6 mm Tread, 2026-27

Chad holds every tyre, on every car, to the same 1.6 mm minimum tread depth — that is essentially the whole rulebook. There is no winter tyre mandate and no studded tyre category to worry about. All-season tyres are accepted without any seasonal swap required.

Whether you are driving your own vehicle or renting one in Chad, knowing what a checkpoint looks at turns a stop into a formality.

Tyre Law Summary for Chad

Tyre Choice in Chad

Chad has no winter tyre regulation and no season that could call for one. The country runs from Sahara in the north, through Sahel around N’Djamena and Lake Chad, to a wetter savannah in the south with a single rainy season in the northern summer. Pick tyres for the surface: reinforced sidewalls for gravel and laterite, deep grooves for the southern mud, and a compound that tolerates hot pavement everywhere.

Minimum Tread Depth in Chad

The tread floor applied for Chad is 1.6 mm, measured across the central three-quarters of the tread width around the full circumference. That is the figure the EU’s tyre directive set in 1989 and the one most of the world’s traffic codes adopted; no separate Chadian number is published in English.

Change at 3.0 mm or earlier. A shallow tread carries less rubber to absorb stone strikes and overheats sooner on hot asphalt.

Tread inspection in Chad: look for the wear-indicator bars moulded into the grooves. When these are flush with the tread surface you are at the floor and the tyre is overdue.

All-Season Tyres in Chad

All-season tyres are accepted in Chad, and no marking is required. For drivers who prefer not to think about seasons they are a practical choice, though an all-terrain tyre suits the unpaved network better.

Penalties for Tyre Violations in Chad

Worn tyres can be picked up at police and gendarmerie checkpoints, which are frequent on the roads out of N’Djamena. The larger risk is insurance: after a collision, a tyre below the floor gives an insurer a reason to reduce or refuse the claim.

Tyre Choice for Chad’s Climate

• Heat: high road temperatures raise pressures and age rubber. Check pressure when tyres are cold and inspect for cracking or bulges
• Rainy season in the south: laterite turns to mud and water pools on the tarmac; tread depth matters most then
• Desert north: lower pressures help on soft sand but must be restored before speed on tarmac
• Age: replace tyres at about six years whatever the tread

Road Conditions and Tyre Wear in Chad

Roads in Chad range from the surfaced routes out of N’Djamena to rough, unpaved tracks across most of the country. That 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 the capital
• Carry a repair kit and compressor alongside a full-size spare
