CINTURATO CA67

1953

In the mid-50’s a radial casing structure and a textile belt were introduced in tyres. The increased stability brought by the belt prevented any unwanted tyre deformation in all conditions. The adherence was greatly increased and the smooth rolling allowed tread wear to be reduced by more than one half in comparison to a cross-ply tyre. Moreover, the use of the belt favored the design of new profiles and tread patterns providing greater grip. Patented in 1951 and regularly put on the market in the mid ‘50s the Pirelli CINTURATO™ has kept the classic tread pattern “367” that made it famous throughout the world for over a decade: in 1966 this pattern was codified with the acronyms CF67/CA67. This name came from the 67 manufacturing licences issued by Pirelli to the most important tyre manufacturers in 25 countries. CA67™ was the first textile radial tyre whose speed code was SR, up to 180 Kmh. Its tread pattern was made of ribbed elements separated by four longitudinal grooves “a greca”, very cut shoulder and wide siping. The tread compound was very resistant to high temperatures and to tearing. In the mid‘60s, Pirelli CINTURATO™ was the reference tyre for the greater part of the automotive industry in the world.
