| -2- Hs{Lord Ernest Hives - Chair}/AJL.1/AJ.7.10.30.Contd. improvement in road adhesion is that has resulted from the modification, because we have not had the opportunity of testing them under the bad conditions that occur on some of the London roads, (wood blocks, etc); from the nature of the modification there is an improvement. One set of these tyres have run on a London Trials Car for 4,700 miles, they report that the wear appears to be less than the standard silent tread. We propose standardising these tyres.
