Sadly currently Dunlop do not make any historic road tyres. For the majority of cars that fitted this tyre originally we would currently recommend the 185VR15 PIRELLI CINTURATO ™ CA67 as the best alternative.
Dunlop 6.40H15 Dunlop RS5
This 6.40H15 Dunlop RS5 tyre will be best known for it's association with Jaguar, where it was fitted on the e-type series 1 and the series 2 XKE, not to mention the MK1, MK2, S-type & 420 saloon cars of the '50s & '60s, and of course their sister cars from Daimler V8 250. In period, if you wanted a radial alternative to a 640-15 tyre, for one of the cars, the best one Jaguar offered, and for that matter the only option that is still produced today was the 185VR15 CINTURATO ™. Also we would suggest that this still one of the best tyres for these cars. If not THE best.
The tyre description 640H15, could be written in a variety of different ways; 6.40H15 6.40 H15, 6.40 H 15, 640H15, 640 H15, 640 H 15, 6.40-15 6.40 -15, 6.40 - 15, 640-15, 640 -15, 640 - 15, 6.40X15 6.40 X15, 6.40 X 15, 640X15, 640 X15 or 640 X 15. However the correct way in period was 6.40H15.
This description means that the width and height of the tyre should be 6.4 inches. (It was in fact 174mm or 6.85 wide, and 6 inches or 151mm tall). The H is the speed rating & means 130mph. The fact there is not an "R" in the description means it is a Crossply tyre and 15 designates a 15" rim.
The overall diameter is 683, which is pretty much the same diameter as a 185VR15 tyre, though a 185VR15 will be slightly wider. So in the case of some cars where you might find the steering heavy the Michelin's 180HR15 XAS might be a useful slightly thinner alternative to a 6.40H15 Dunlop RS5.
The Overall Diameter of the 670 H 16 Dunlop RS5 is 683 mm and the width is 174 mm.
