185. Tyres
Tyres are the rubber components fitted around a vehicle's wheels that provide contact with the road. They transmit braking, acceleration and steering forces and play an important role in vehicle stability and road holding.
Tyres should have sufficient tread depth, correct pressure and no serious damage or excessive wear. Drivers should use tyres that are suitable for the vehicle and regularly check their condition, particularly before long journeys or driving in difficult weather.

What is the minimum tyre tread depth in Belgium?
For cars, the principal tread grooves must be at least 1.6 mm deep. The principal grooves are the broad grooves in the central part of the tread covering approximately three quarters of its width.
Are tyres checked during Belgian technical inspection?
Yes. Tyres are checked as part of the vehicle's wheels, tyres and suspension inspection. Checks include tread wear, damage and whether the tyres meet the applicable technical requirements.
Must tyres on the same axle match in Belgium?
During technical inspection, tyres on the same axle must have the same dimensions and the same construction type, such as radial or diagonal. Using matching tyres on the same axle is also recommended for predictable handling.
