In reply to your Hs{Lord Ernest Hives - Chair}/Rml/MJ.3.6.30. how are we going to form an adequate opinion as to these tyres with only two?. Can you arrange please to have four tyres here in order that the full deceleration and extent of silence may be gauged over the whole car relatively to previous effects with the ordinary treads.
