This tyre is dimensioned more like one would call a dual marked 650/700x19. Dual marking is a more "recent" invention as one cannot have 2 tyre sizes with one tyre, and it has come about when a manufacturer uses the larger size mould and re engraves it with the smaller dimension. In our case because we were starting from scratch we designed this tyre to be a 650x19 tyre with a very generous tread width. There were not many cars in Europe fitted this larger size, but many cars such as 20/25 Rolls Royce owners like fitting this tyre over the smaller width and diameter 600x19's they left the factory with.
All Blockley Cross (Bias)ply tyres are made to fit the original rim widths, something other manufacturers have forgotten about over time. In addition they are genuine tyres for road use, with a robust sidewall and covering, capable of being 'curbed' as you would expect from a tyre suitable for road use. The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded. We liked the period look of the triple stud tyre, so we re-designed all features of this pattern to make it work correctly without wearing out in no time. The compounding of all our cross (Bias) ply tyres conform to FIA Appendix K which uses Dunlop 204 compound as its reference hardness. This same Blockley tyre, surprisingly, has no equal having won many thousands of races and other competitions as well as Concours d'Elegance events, including class wins and overall best of show at Pebble Beach!.
This is why we coined the term Road Race for tyres when we started. Which has been copied (as have many of our tyres) by the classic tyre wholesalers who we do not sell through. So beware of imitations!
All Blockley tyres are made with new moulds and tooling and a high level of quality control, resulting in a product of unsurpassed quality, roundness and conformity.
