You may remember that I was inclined to be doubtful as to the wisdom of fitting India tyres on the Bentley. After having tried them, I am quite convinced that your decision to fit them was correct. The back tyres did 6,250 miles, which I think is about the highest mileage I have ever had on back tyres on any car that I have owned. For experimental purposes, I replaced the original India back tyres with two Dunlop standard covers; these have now done 2,000 miles, and are practically worn out. Given dry weather, they will probably do another 500 miles, but even now they are not safe on wet roads. There is another feature too, and that is that the car is not so stable with the Dunlops on the back as it was with the India. With regard to the front, these have done between 8,000 and 9,000 miles, and there is still quite a lot of tread left on them. I should imagine they will do between 12,000 and | ||
