In Ukrainian vehicle technical regulations, what is the statutory minimum tyre tread depth for passenger cars (Category M1)?

Answer and explanation

Correct answer: C. 1.6 millimetres across the principal tread grooves

  1. Step 1: Under Ukrainian Traffic Regulations (PDR) and vehicle safety standards, PDR paragraph 31.4.5 mandates at least 1.6 mm of tread depth for passenger motor cars. Answer: 1.6 millimetres across the principal tread grooves. Why not the others: 1.0 millimetre for summer tyres does not represent the statutory Ukrainian safety requirement.
