Question 629 of 1002

Which statement about studded tyres is correct?
Justification

Studies show that studded tyres generate about 5-20 grams of dust per km driven per tyre. This is about 100 times that of cars fitted with non-studded tyres.

You therefore risk raising up to 1 kg of road dust by driving 10 km with studded tyres.
Options
Tread depth must be at least 1.6 mm
Studded tyres harm the environment with dust, noise and wear
Tread depth must be at least 6 mm
It is always mandatory to use studded tyres in winter
