Tunisia Tyre Rules 2026: No Winter Law, 1.6 mm Floor

Tunisia has no winter tyre law. No date window, no marking requirement, no stud season. The only tyre number that carries legal weight here is tread depth, and the figure to work to is 1.6 mm — the European benchmark set by Council Directive 89/459/EEC, measured in the main grooves across the central three-quarters of the tread.

Worth knowing: the common line that Tunisia never gets cold is wrong. Ain Draham, in the Kroumirie highlands behind Tabarka, sits at around 800 m and records snow most winters. There is still no tyre mandate there — the authorities close or grit the road instead.

Tyre Law Summary for Tunisia

Where the 1.6 mm figure comes from

Tunisia does not publish a tyre-specific tread table of its own in the way Austria or Czechia do. The 1.6 mm used throughout this page is the European figure, and it is worth reading the directive’s own wording: tyres must “have a tread depth in the main grooves of the tread surface of at least 1,6 mm”, with main grooves defined as the broad grooves covering “about three-quarters of the width of the tread surface”.

That matters practically. A tyre with 4 mm on the shoulders and 1.4 mm down the centre is not legal anywhere that applies this standard, and centre wear is exactly what over-inflation on hot Tunisian motorway runs produces.

Heat, not cold, is what kills tyres here

Sfax and Tozeur see summer air temperatures in the forties; road surface temperature runs far higher. Two things follow:

• Rubber hardens with age, not just use. UV and heat oxidise the compound. A five-year-old tyre with 5 mm of tread can have measurably less wet grip than a two-year-old at 3 mm. The DOT code on the sidewall is the only honest way to check.
• Pressure readings drift. Set cold pressures in the morning. A tyre checked after two hours on the A1 will read high, and bleeding air down to the door-sticker figure leaves you under-inflated once it cools.

When the rain arrives

Tunisia’s wet season is short and concentrated, roughly October to February in the north. Wadis cross roads, drainage is limited, and standing water on the P1 and the coastal roads builds fast. Tread depth is the whole story for aquaplaning resistance: the grooves have to move the water, and at 1.6 mm there is very little groove volume left to do it with. Three millimetres before the autumn is the sensible target.

Away from the tarmac

South and west of the coastal strip, secondary roads degrade into gravel, broken edges and drifted sand. What actually strands people is sidewall damage, not tread wear.

• Carry a full-size spare. Space-savers are speed-limited and useless on a long desert leg.
• Drop 0.2–0.3 bar for soft sand, then reinflate before returning to tarmac. Running low pressures at speed destroys a sidewall.
• Inspect both walls after every rough section, including the inner face, which is where flint cuts hide.

Crossing out of Tunisia

Tunisia has exactly two land neighbours:

• Algeria: no winter tyre season, 1.6 mm tread, studs not used.
• Libya: no winter tyre season, 1.6 mm tread, studs not used.

The bigger change happens on the ferry. Sailings from Tunis–La Goulette land at Genoa, Civitavecchia, Palermo and Marseille, and from that point European winter rules apply: Italy runs signed seasonal obligations on many routes, and France enforces the Loi Montagne in its mountain departments from 1 November to 31 March. Shipping a Tunisian-registered car north in winter means checking the destination’s rules, not Tunisia’s.
