HC Deb 15 February 1979 vol 962 cc594-5W
Mr.Moate

asked the Secretary of State for Transport (1) whether he has any plans to increase the minimum tread depth for the tyres of motor cars

(2) if he estimates that an increase in the current minimum tread depth of motor car tyres from 1 mm to 2mm would produce a significant reduction in the number of road accidents.

Mr.Horam

We do not propose to increase the current minimum tread depth for car tyres. Research by the Transport and Road Research Laboratory suggests that there would be no significant safety advantage in this.
