Blisters

Sir,

I have experienced, after 10,000 and 15,000 miles respectively, large blisters on the walls of two Dunlop Gold Seal C41 tyres on my M.G. 1100. My son had the same trouble with the same type of tyre on his Morris Mini-Minor.

Let us hope that Dunlop racing tyres and those used by Donald Campbell are not made in such a shoddy fashion. Surely one neck is as good as another?
