Pirelli cinturato cn54: A new vintage tire for fiat 500 collectors- fiat club america

Pirelli launched a new tire for the iconic Fiat 500: the car that symbolized mass motoring in Italy. This new tire is part of the Pirelli Collezione range: tires dedicated to cars from 1950 to 1980, which combine a classic look with modern technology. A HIGH TECHNOLOGY TIRE For all the different versions of the Fiat 500 that were made since 1957, Pirelli has recreated the Cinturato CN54 in 125 R 12 size, which was originally launched in 1972. This is a radial tire with a tread pattern design and sidewall that are similar to the original, but made with modern technology. Pirelli Collezione tires use contemporary compounds to offer increased grip and improved road holding on wet surfaces, guaranteeing reliability and high safety standards without compromising the original style. Throughout the tire’s research and development program, Pirelli’s engineers used the same parameters that the original vehicle designers used, in order to perfectly complement the suspension and chassis settings of the car. To achieve this goal, they referred to original materials and designs housed in the Pirelli Foundation archives in Milan. PART OF THE FIAT 500 STORY FROM THE START The Fiat 500 was born in 1957. The tire size was a conventional 125 12, featuring either the Cisa tread pattern, the tried-and-trusted Stelvio, or the Rolle design that was also available for the larger Fiat 600. The Fiat 500 range would expand over the years, from the original N version to the D that was presented in 1960. This version was the first car to adopt Pirelli’s Sempione “Safety Shoulder,” featuring more rounded sidewalls for better road holding through corners. The Fiat 500F came out in 1965, followed by the L in 1968, both with Pirelli 12-inch tires. When the R version was launched in 1972, the Pirelli Cinturato range was sufficiently wide that Fiat’s runabout could also have a radial CN54 tread pattern, in 125 R 12 size. This is the tire that Pirelli is recreating for owners of this classic Italian icon. The CN54 of the time was directly derived from rallying experience, maintaining the tread pattern design of the classic CA67 – which made the Cinturato name famous all over the world, thanks to a new belted structure that improved both comfort and tire life. PIRELLI COLLEZIONE, HISTORY ON THE ROAD The Pirelli Collezione family was born with the goal of preserving automotive history through tires that serve a dual purpose: maintaining the look and driving feel of the original versions, and improving efficiency and safety thanks to modern technology and production processes. The range started with the legendary Stella Bianca, first launched in 1927. Then, in 2018, Pirelli brought back to life the Stelvio to exclusively supply the Ferrari 250 GTO – the most expensive car in the world – together with the CA67 (1955), CN72 (1964), CN36 (1968), CN12 (1968), Cinturato P7 (1974), P5 (1977), P Zero (1984) and P700-Z (1988). Throughout the development process of these reborn tires, Pirelli’s engineers used the same vehicle parameters that the original designers would have relied upon at the time, but using all the know-how and experience when it comes to materials and production processes that have been built up in the meantime. The result is a compelling mix of performance, style, and authenticity. The images, plans, and other materials supplied by the Pirelli Foundation archive were a fundamental part of this process. The Foundation has kept all documents relating to the design, development and production of every Pirelli tire over the years: including homologation certificates, mould designs, tread pattern studies and testing results, as well as price lists and catalogues. For information on local availability of Pirelli Collezione tires please check on www.us.pirelli.com or contact Pirelli’s flagship P ZERO World store in Los Angeles by phone 310 203 3900 or via email pzeroworldLA@pirelli.com PIRELLI’S OFFER IN NORTH AMERICA. Pirelli's offer for the U.S. is wide and complete, with a range of products designed specifically for consumers in this market. The Plus product line, for example, was born out of the strategy to create a simple, yet comprehensive product portfolio for American needs: namely the popularity of vehicles such as SUV / CUVs, and the trend for more mileage per vehicle. The champions of this line are for sure the Scorpion Verde All Season Plus II (the eco-friendly tires for the Crossover and SUV segment) and the Cinturato P7 All Season Plus II (tires specifically designed for the North American touring market). Pirelli also has a dedicated product for off-road lovers: the Scorpion All Terrain Plus. And then, there is of course the hero of the Pirelli product range: the P Zero, chosen as original equipment for most performance-oriented and powerful models on the market.

Is there any input on wheel size. My 750 has 13" wheels, and Pirelli tires. I have 12 wheels available. Opinions please.

Wes not to hijack this thread you can look for more picture of this car in Image Section under 260452

Corsa debate will not be opened for awhile.

Thanks John. I love the tread pattern on the XZX. Would be great to see them once mounted.

Before on the right. Spare went a smaller size. Not sure if that was correct. Would love to hear from other posters.

Recently purchased 145/70R12 Michelin XZX from Coker Tire the price was 78.00 US each. I'm happy with

with ride and look. i will post some pictures.
