Muchas veces cuando se compra un coche se recibe una herencia involuntaria, muchas veces envenenada, o simplemente inutil; una rueda de repuesto por la que no ha pasado el tiempo, o mejor dicho, por la que SI ha pasado el tiempo, pero nadie lo ha mirado pasar esas dudosas reliquias que descubrimos al levantar la tapa del maletero a veces son anodinas, pero cuando hablamos de coches de 30, 40 o 50 años, pueden ser verdaderas curiosidades, modelos que ya no se fabrican y que revelan dibujos, perfiles, formas de lo mas curiosas. Quiza todos conocemos el Michelin XWX con forma de hojas de roble cruzadas, pero tuvo que haber muchos otros... si teneis por ahi alguna foto, se podrian compartir contando un poquito de historia, voy a empezar con esto.... la PIRELLI CINTURATO CN36 un dibujo muy llamativo que aparecio en 1968... The CN36 PIRELLI CINTURATO ™ was introduced in 1968 as PIRELLI's 70% profile, high performance range of tyres and is well known for it's fitment to Porsche 911 and Ford Escort Mexico. PIRELLI CINTURATO ™ CN36 Tyres PIRELLI's CN36 is the perfect low profile tyre to be fitted as a period upgrade to a full profile tyre without spoiling the handling of the light weight rear wheel drive sports cars of the 60's & 70's. The Cinturato's rounded shoulders have been developed to run in conjunction with the car technology of the day. So cars like MGB, Alfa Romeo Spider, Giulia & Alfetta that originally ran on a 165HR14 full profile tyre might want to increase their foot print by fitting the 185/70VR14 CN36 CINTURATO ™. la publicidad de la epoca muestra un neumatico muy curioso, alejado de la lineas longitudinales en el manual del usuario del Bavaria (conocido como E3), aparecia asi el uso del gato... el neumatico se parece mucho al CN36, aunque tampoco es exactamente igual, me pregunto si algun otro fabricante que no fuese pirelli intento seguir ese diseño en 2016 Autobild-klassic probo varias ruedas: en seco y mojado, y estos fueron los resultados
y esto, posiblemente lo mas raro que haya visto nunca: The Incredibly Strange Pirelli BS3 Tire Featured Removable Tread You Could Change Yourself By Thomas Hundal August 25, 2022 3:48 pm 19 Comments Normally, tread separating from a tire is a sign that something’s gone catastrophically wrong. Be it due to manufacturing defect, dry rot, or simply heavy wear, tread separation is typically marked by incessant thwapping followed by destroyed quarter panels. But what if tread separation was a feature rather than a defect? Meet the Pirelli BS3, a tire from which the tread was meant to separate for the sake of year-round driving. Wait a second, what about the BS1 and BS2? Well, they didn’t really exist. The letters in the BS3 alphanumeric stand for battistrada separata, or separate tread, and the 3 stood for the three tread bands. Here’s how the BS3 worked: Tread bands were available in both summer and winter tread patterns and could be slipped on simply by deflating the tire casing. Once the pressure was pumped back up, grooves and air pressure would work to hold the bands to the tire carcass. No adhesives, no bonding through vulcanization, no problem, right? Photo credit: Pirelli According to Fondazione Pirelli, this absolutely insane tire was the brainchild of two men: Giuseppe Lugli and Carlo Barassi. See, back when Lugli was in charge of the Pirelli Rubber Sector’s Physics Laboratory, he imagined a tire with separate tread and casing, an idea that never really got off the ground at first. Barassi then refined this concept, starting with a special tire carcass and separating the tread into three bands kept apart by precipitation-evacuating channels. The channels also served two extra purposes; to keep the tread bands in place and allow fitment of tungsten spikes for winter use. Barassi then pinched a summer tread pattern from the Pirelli Cinturato 367, whipped up a winter tread pattern, and unleashed the BS3 at the 1959 Turin Motor Show. Photo credit: Pirelli To showcase the effectiveness of the BS3 in slick conditions, Pirelli slapped a set of BS3s on an Alfa Romeo Giulietta and had skaters in really short dresses chase the car around an ice rink. I’m not sure if the skaters’ outfits were necessary for this publicity stunt, but it was Italy in the 1950s so I’ll just roll with it. While this was certainly a neat ad, the real marketing genius came by partnering with the Autogrill network of roadside restaurants and service stations to sell and install BS3 tread bands along the Autostrada del Sole running from Milan to Naples. Presumably, the idea was that owners of BS3 tires could get winter or summer treads swapped on while they had a light snack. Of course, the promotional displays for the BS3 would also alert other motorists of the tires’ presence. Not a bad plan if you ask me. ADVERTISEMENT Pirelli was immensely proud of its BS3 tire, so in addition to print ads, the Italian company took out some airtime to promote this tire innovation. Check out the BS3 spot some two minutes and 33 seconds into the above compilation of ads. While the ad likely provided decent exposure for the tire, I’m not sure what I learned from this advertisement other than to not use a giant flower as an umbrella during wintertime. In fact, it’s worth watching the entire video because it’s absolutely surreal. In addition to the strange visuals, the backing tracks consist almost entirely of slapstick sound effects, creating the ambiance of comedy collapsing in on itself. [Editor’s Note: Agreed; you should watch that. It’s out there. -DT] Photo credit: Pirelli So, did the Pirelli BS3 actually work? Well, yes and no. Motorsport Magazine had a less than stellar experience with BS3 tires during an outing at the Nurburgring. While testing an Auto Union 1000, a band detached from a rear tire, creating a little bit of a situation. The spontaneous mobile tread band evacuation likely caused a great deal of fuss in the Pirelli press office, as a comparison test between the BS3s and Pirelli Extraflex tires was quickly arranged. Not just some parking lot cone work, this comparison test consisted of a tour of Britain and circuit lapping at Oulton park. Bold stuff. While some rubber came detached, the tread bands stayed put, and Motorsport Magazine had some very kind words for the BS3 tires. […] but it is significant that each improved his lap times by approx. 5 sec. when using the BS3-shod Oxford. These tyres at first give a feeling of instability, due to their flexible casings, but their superior grip soon becomes evident and corners begin to be taken in impressive drifts. It was particularly noteworthy that whereas the Extraflex screamed loudly as tyres do when tortured in this fashion, the BS3s were uncannily quiet. This silent running is a valuable asset to those who like to hurry round corners and roundabouts without attracting unwelcome attention. Driving like a nutcase without raising suspicions sounds quite nice, although it sounds like BS3 tires had some very strange handling characteristics. In addition, Pirelli notes that 23 of the 26 BS3-equipped participants in the 1961 Monte Carlo rally finished — a fairly strong showing for the tire. Still, the remote possibility of tread detachment was one that lingered, and the tire’s patented nature meant that imitators didn’t really exist, preventing a wider audience from discovering the joyful weirdness of swappable treads.

However, the BS3 spawned a tire much closer to Giuseppe Lugli’s original concept, this time simply called the BS. It may have featured a name that didn’t translate well to English, but it soldiered on until advances in cars and tires consigned detachable treads to the dustbin of history. While we haven’t seen anything like the Pirelli BS3 in decades, it holds a very important place in tire history. Per Pirelli, lessons learned from the BS3 and the subsequent BS were put into practice with Pirelli’s first dedicated winter tire, the MS35. ADVERTISEMENT Not only did Sandro Munari win the 1972 Monte Carlo Rally with a Lancia Fulvia shod with Pirelli MS35 winter tires, Pirelli kept developing winter tires, pushing them to places they’d never been before. Today, Pirelli makes Ice Zero winter tires for icy conditions, Scorpion winter tires for SUVs, and Sottozero winter tires for really fast stuff like the Lamborghini Huracan and the Porsche 911. It’s strange to think that in a way, the very peculiar Pirelli BS3 is partially responsible for being able to truly enjoy Lamborghinis in the snow. That’s not a bad legacy if you ask me.
recreandome en los posters antiguos, y calendarios, que cosas... en los 50, y 60, parece pintado, irreal hay que reconocer que no consigo encontrar la relacion de la imagen con los neumaticos, parece un Avedon, por el estilo, rezuma lujo, sensualidad, quiza la yola disponga de proteccion perimetral a base de cubiertas pirelli, pero,...que mas da... el cn36, lo gordo es bello y si, he encontrado a continental con un perfil similar pero aplicado a nieve y este dunlop es el que luego ha copiado Blockley... precioso firestone... este anuncio no lo entiendo bien,...puede que la persona este revisando el manual de instrucciones para acometer alguna accion sobre la rueda ?
Hay que reconocer que los neumáticos antes tenían diseños de bandas mucho más artísticas, no sé si tan efectivas... pero eso ha pasado a mejor vida... Me encanta el dibujo de la BFGoodrich Radial T/A
Lo malo es que solo sirve como adorno en el garaje como tengo yo mis llantas con TRX colgaditas bien limpitas... , un collage industrial
