Built initially for the 8 litre Bentley and Rolls Royce Phantom 1.  The first set of these tyres was put on the 8 litre Bentley now owned by Bentley Motors. This superlative handling tyre has also been used on the 24 litre Napier-Railton which is used regularly by the Brooklands Museum, which we were complimented on after it was driven for the first time on them. 

All Blockley Cross (Bias) ply tyres are made to fit the original rim widths, something other manufacturers have forgotten about over time. In addition these 700x21 tyres for genuine 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 The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded.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.
