All Blockley Cross (Bias) ply tyres are designed 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, as designed by us and 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 The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded.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!

The 450/500x18 Blockley tyres are made using new made moulds and tooling and a high level of quality control, resulting in a product of unsurpassed quality, roundness and conformity. And finally, don't forget we also produce a Blockley correctly sized thicker butyl inner tube that we made specially just for this tyre, with both rubber stems and as tubes were prewar, metal valve stems.
