Dunlop’s signature quality, crossply tyre of the 1930s, the F4 was the fitment of choice for the most luxurious cars of the period. As such it remained in production for the classic-car market until Fort Dunlop finally closed in the 21^st Century! It’s sculptured sidewall and shoulder are extremely recognisable, and a symbol of quality. Vintage Tyres have developed a replacement F4 pattern tyre via its historical relationship with Dunlop, and using original moulds. The result is manufactured in the UK as the Ensign F4, and is available in various sizes to fit 17 to 21 inch wheels.

This 525/550/600-20 size Ensign F4 is the ideal tyre for: Rolls Royce 20hp; Alvis Speed 20; Bugatti Type 46 and 50; Daimler Double Six; Itala 65 Sports; and Voisin C14 and C23.

This is a tube-type crossply car tyre.
