A popular tyre on cars such as Derby Bentley, SS Jaguar and Type 57 Bugatti's. Standard fitment on the Suffolk SS100 after they tested them and found them to be far superior to anything they had experienced previously with excellent longevity. Like other Blockleys in the range, the 550 x 18 is the best handling tyre on the market.

Please note we also make this 5.50 x 18 size with an alternative tread 'A6C' pattern.

To emphasise the quality Roger Kraus Racing in the USA arranged a drum testing of this tyre ( in buffed condition) at 400 mph for record use at Bonneville!

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 The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded.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.
