§ VISCOUNT HANWORTH
asked Her Majesty's Government:
In view of the danger of mixing radial and cross-ply tyres on a car and of the regulations relating to this, they will make the marking of all new tyres as radial or cross-ply compulsory.
§ BARONESS YOUNG
No. In practice manufacturers both in the United Kingdom and elsewhere mark all radial tyres with the letter "R". A more comprehensive system of tyre marking is likely to be agreed shortly under the aegis of the Economic Commission for Europe and to be implemented subsequently by Her Majesty's Government.
