5.50 x 15 cross(bias)ply tyre with the Blockley trademark 5 block tread pattern, made to Dunlop’s ‘L’ section dimensions. This Blockley Cross(Bias)ply tyre is made to fit the original rim widths early TR’s had in period and are manufactured 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 of the period is reproduced in this tyre suitably re-designed to remove an unfortunate wear characteristic of the original. The compound of this cross(Bias)ply tyre conforms to FIA Appendix K, using Dunlop 204 compound as its reference hardness. This type of Blockley tyre 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.

All Blockley tyres are made with new moulds and tooling with a high level of quality control, designed in house, resulting in a product of unsurpassed quality, roundness and conformity.
