Hot gossip!

A lorry turned up at our gaff yesterday with a delivery of 175HR400 Pirelli Cinturato CA67. (and some 145R14 for the Lancia Fulvia)

175HR400 is a pretty bespoke tyre. There aren't many tyres we sell less of. For you early Ferrari guys some 1950s cars fitted 400mm wheels, because as much as anything radial tyres were much easier to get hold of in a 400mm size in the early 1950s becuase of the Michelin X, However the Pirelli Cinturato (of 1952) rocked the world of sports cars by making a radial tyre that was good for sports cars. yes like the Cinturato, the Michelin X gave better grip, but it didnt go round corners anywhere near as well as a Cinturato, becuase it wasn't Progressive. In those days rear wheel drive cars with out traction control, it wasn't all about grip, it was about predictable progressive handling, where you drove the car on the throttle pedal, this is where the step from Crossply to radial on cars originally built for crossply these Cinturato hold there own.

These are a couple of pages from a book about Pirelli's victories in 1954.

We do also have 600V16 Stella Bianca for earlier cars on 16" wheels. and that range has been expanded with a 550-16 and even now for the first time in years an actual performance crossply in the size 500/525-16 which loads of racing cars like 1950s Ferrari and the 250F fitted on the front.

and of course the 185VR15 Cinturato CA67 is on the shelf. we have new stock items and we still have some of the old date code available at only £ 200!

then 205VR15 CN72 for the post 1964 cars and hopefully a 14" version in the pipe line.

And of course loads of XWX
