§ Sir G. Nabarroasked the Secretary of State for the Environment whether he will publish particulars of the costings which have prompted his decision to reject the proposition from the hon. Member for Worcestershire, South to increase the minimum tread of all tyres in use on motor vehicles in the United Kingdom from 1 millimetre to 1.59 millimetres in consonance with the minimum tread in the United States of America; what technical considerations are inherent in his rejection of the proposition; and whether he will make a statement.
§ Mr. PeytonVery broad estimates suggest that the extra cost would be at least £10 million a year for no certain benefit.
