Correct answer
1.6 millimetres
It is 1.6 mm under Annex VII.2 of the General Vehicle Regulations. The question specifies an M1 car: this is not a universal minimum for every vehicle. Check main grooves and wear indicators, alongside damage, pressure and overall condition. Meeting that minimum does not guarantee grip or replace adapting driving, particularly on wet roads. Recommendations for earlier replacement do not change the legal minimum. This case excludes the limited Annex VII.2 exception for certain historic vehicles.
