All car tyres sold from 1st July 1997 must carry an ‘E’ marking. The ‘E’ or ‘e’ mark consists of an ‘E’ or ‘e’ followed by a number included in a circle of 12mm diameter or a rectangle. This symbol is followed by a further number.
The ‘E’ certifies that the tyre complies with the dimensional, performance and marking requirements of ECE Regulation 30.
The ‘e’ certifies that the tyre complies with the dimensional, performance and marking requirements of DIRECTIVE 92/23/EEC.
The number associated with the letter ‘E’ in the circle or ‘e’ in the rectangle is the code number of the government which granted the type approval (No. 11 for the British Government and a different identifying number for each of the other European countries involved).
The number outside the circle or rectangle is the number of the type approval certificate issued for that particular tyre size/type.
