| contd :- -2- it aims at. As we have not previously had a 7" tyre in the Works for 21" rims we can only tell you from those which have been received on production that they are out of the question for our present cars as they will not fit existing spare wheel carriers. The only 7" tyre which we think likely to interest us is one on a 20" rim which we are at present testing. As we are not satisfied with the present silent tread tyres, we feel sure you will do your best to co-operate with us in getting what we require to our mutual satisfaction. Yours faithfully, | ||
