A big and robust, eight ply rated tyre used typically on cars such as Rolls Royce Phantom 2, Bugatti Type 50 and some Vintage Mercedes, resulting in truly impeccable road manners even at high speeds. We know this from personal experience of driving with 650/700x20 Michelin DR tyres previously, and realised the urgent need to make this size.  This 700x20 Blockley tyre is also suitable for many historic commercial vehicles and trucks. These tyres have also seen use on the 24 litre Napier-Bentley special.

Prior to Blockley making this tyre size, the only alternative was the weak handling Michelin, or a Dunlop offering made in the old truck moulds, which made the cars it fitted not only look terrible, but the tyres were virtually solid.

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 are genuine tyres for road use, with a good 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 The Dunlop triple stud pattern in period was a problematic one, which resulted in it being superseded, but we liked the period look of the triple stud tyre, so we re-designed all features of this pattern to make it work correctly, and to make sure it doesnt wear out in no time, in addition to the superb ride and handling characteristics.

This 7.00x20 tyre size was also known in period as 34x7.00 as well as 32x6.75

All Blockley tyres are made using newly manufactured tyre moulds and tooling to our specifications, based on researching the original details. Along with a high level of quality control this results in a product of unsurpassed quality, roundness and conformity.
