Bolivia sets no winter tyre season. The tread minimum is 1.6 mm at any altitude, but the Altiplano freezes overnight from June to August and the Yungas descents load tyres and brakes hard.

Tyre details
- How the EU tyre label grades wet braking and rolling resistance — What each letter and pictogram on the sticker actually measures.
- What the speed letter on the sidewall allows — H, V, W and Y decoded, plus the sticker rule for lower-rated winter sets.
- Reading the load index before you buy replacements — The two- or three-digit number that caps weight per tyre.
- Tyre noise ratings in decibels — What the dB figure and the A, B or C class on the label mean inside the car.
- Calculate tyre pressure from your tyre size and load — A starting figure in bar and psi, then the door placard has the final word.

See how Bolivia differs from your home country
Bolivia has no winter tyre season in its rules. That is a legislative fact, not a climatic one — because this is a landlocked country whose western half sits on an Altiplano above 3,600 metres, where the dry winter of June to August brings hard overnight frost and daytime sun in the same twenty-four hours.
The tread figure is 1.6 mm in the main grooves, and it applies identically at 4,000 metres and in the lowlands at 400.
Tyre Law Summary for Bolivia
| Regulation | Status |
|---|---|
| Winter tyres | No rule, no season |
| Required period | No set period |
| Minimum tread depth | 1.6 mm |
| Practical change point | 3.0 mm |
| Studded tyres | Restricted |
| All-season accepted | Yes |
Altitude, not season, is the organising fact
Bolivia asks more of a set of tyres in a single day than most countries ask in a year. A drive from El Alto, above 4,000 metres, down into the Yungas passes through several climates in a few hours.
Three consequences worth planning for:
- Pressures move. Both altitude and the Altiplano’s enormous day-to-night temperature range shift the reading. Set pressures cold, to the door-sticker figure, and re-check after a major altitude change rather than trusting a number taken two days and two kilometres of elevation ago.
- Descents cook brakes and tyres together. Long continuous braking is how people get into trouble on the Yungas and the drops towards Santa Cruz. Use a low gear and plan cooling stops.
- Dawn ice is real on the Altiplano. Between June and August the surface can be frozen at first light and completely dry by mid-morning. Nothing obliges you to fit anything different; the answer is to start later or drive to the conditions.
Surfaces that cut rather than wear
Much of the network away from the main corridors is gravel or graded volcanic material. It removes rubber slowly but cuts shoulders quickly. Inspect both sidewalls after each unsealed section — a cut sidewall is not repairable, however much tread remains.
If your route includes the Salar de Uyuni, the tyres are the least of it: brine finds every crevice and corrodes wheels, brake hardware and the underbody. Wash the vehicle thoroughly the same day.
Bolivia’s neighbours
Five countries share a land border, and two of them do have seasonal rules that Bolivia lacks:
- Brazil: no winter tyre season, 1.6 mm, no studs.
- Peru: no winter tyre season, 1.6 mm, no studs. Similar Andean terrain on the far side.
- Chile: a seasonal rule applies in the southern regions from June to September, and studs are permitted in season. The Tambo Quemado crossing tops 4,600 m.
- Argentina: a seasonal rule applies in Patagonia and the Andean provinces from June to September, with studs permitted in season.
- Paraguay: no winter tyre season, 1.6 mm. The Chaco road is long, hot and remote.

Frequently Asked Questions
No. There is no seasonal tyre obligation in Bolivian rules, even on the Altiplano where night temperatures fall below freezing through the dry winter months of June, July and August.
1.6 mm in the main grooves, applied the same on the Altiplano and in the lowlands. Given how much of the network is unsealed, changing nearer 3 mm is the practical rule.
Pressure readings shift with both altitude and the large day-to-night temperature swing on the Altiplano. Set pressures cold to the door-sticker figure, and re-check when you have gained or lost a kilometre of altitude.
Heat. Dropping from around 4,000 m to under 1,500 m in a short distance puts continuous load into brakes and tyres. Use a low gear, stop to let things cool, and never brake hard on a wet, unsealed hairpin.
The salt crust itself is not hard on tyres, but brine is highly corrosive to wheels, brake hardware and the underside. Wash the vehicle thoroughly, including the wheel wells, as soon as you are off the salt.
Five: Brazil, Peru, Chile, Argentina and Paraguay. Bolivia is landlocked. Chile and Argentina both have seasonal winter tyre rules in their southern and Andean regions, unlike Bolivia.
