A popular tyre fitment on cars such as the Derby Bentley, SS Jaguar and Type 57 Bugatti's. This Blockley 550x18 is also the standard fitment on the Suffolk SS100 after these tyres were tested on the factory demonstrator and found to be far superior to anything they had experienced previously - prior to this Suffolk had been using Dunlop tyres for over a decade, and teh Blockley tyres transformed the handling. Like other Blockley tyres in our 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 a different tread pattern we call the A6C pattern, as an alternative choice.

To emphasise the quality of the Blockley 550x18, Roger Kraus Racing in the USA arranged a drum testing of this tyre ( in buffed condition) at 400 mph to see its suitability for high speed use at Bonneville, pretty good for our Blockley tyre which we made for road use - but it gives an indication of the quality of what Blockley produces.

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 The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded.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. There is nothing produced that is this good!
