| JOHN SUMMERS & SONS, LIMITED, SHOTTON, CONTINUANCE No. 1........ and 14,000, which would again be the highest mileage that I have ever obtained. There is one other comparatively unimportant feature that I have noticed, and that is that the India tubes do not appear to lose air as rapidly as the Dunlops. I feel pretty sure that other people will withdraw their criticisms on the India tyres when they have seen what service they will give. I shall do no more experimenting, but shall continue to use India tyres. Yours sincerely, Richard. RFS/HC. | ||
