Correct answer
B. 1.6 mm.
Explanation
In the photo there is the rear wheel of a moped with a tyre, a disc brake and a shock absorber. The minimum tread depth of a tyre without a wear indicator is 1.6 mm - answer B.
The rules on the technical conditions of motor vehicles forbid the use of tyres whose indicators show the tread wear limit, and, for tyres without such indicators, tyres with a tread depth of less than 1.6 mm. The Regulation on the technical conditions of vehicles does not give a separate value for a moped, so the same limit is used when assessing its tyres. The value of 2.6 mm (answer A) is a safety margin, not the minimum required by law, and 1.1 mm (answer C) is already a worn tyre. The tread clears water from under the tyre - with a shallow tread on a wet roadway the wheel easily loses grip, which on a two-wheeler ends in a fall. Also check that the tyre has no cracks and that the pressure matches the manufacturer's recommendations.
Legal basis: § 11 para. 7 point 4 of the Regulation on the technical conditions of vehicles and the scope of their necessary equipment (a rule for motor vehicles, applied to mopeds as a minimum); Art. 66 para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym)
