    New rear tyre from Pirelli for RSR and later cars in the size 215/60VR15 CN36

    Hi

    For some time now we have had the 165HR15 Cinturato CA67 https://www.cinturato.net/165-15 as an original tyre for early cars. However, in this size, there has always been some good options of top quality tyres such as the Michelin XAS http://www.longstonetyres.co.uk/page...helin-xas.html which was also a period option from 1965

    Recently also Pirelli re made the 185/70VR15 CN36 https://www.cinturato.net/185-70-15 which as well as being an excellent tyre also looked fantastic.

    However the braking news it that they are also about to reproduce the 215/60VR15 tyres that were fitted to some cars after (i think) 1973. I don't have a date of production as yet but it is good news all the same. Currently there isn't actually a perfect set up in these sizes. Granted there is the P6000 http://www.longstonetyres.co.uk/page...-p6000-n2.html which is an excellent tyre for modern cars; but the carcass is not suited to cars of that period (and they look wrong). Avon make the CR6ZZ http://www.longstonetyres.co.uk/page...von-cr6zz.html which again offers a matching front and rear, again fantastic tyre and they will drive better because the caracase has the rounded shoulders that cars of this period suit, but they are a road race tyre really and again they don't look right. so a genuine period front and rear tyre made by Pirelli will be excellent Name:  IMG_2576.jpg

    Finally! Been hoping for these to put on the RS for a 'gazillion' years.

    Curious Doug, where do you see this announced? I don't see any news of the 216/60s coming on the Pirelli website. Thanks.

    I know about it because i sat in a meeting with Pirelli discussing the future production of the Cinturato historic range. They have already made the 185/70VR15 CN36 http://www.longstonetyres.co.uk/page...elli-cinturato for me that was fitted front and rear pre 73, and the 165HR15 CA67 http://www.longstonetyres.co.uk/page...rato-ca67.html that was fitted pre '68. I have a Lancia Aurelia tyre on the way, a low profile option for MGB and Alfa Giulia, a tyre for the Ferrari Dino and one for 70's Ferrari & XJV12 Jaguar. and one of the other tyres in for production in the near future is your rear.

    Any discussion about re-releasing the Cinturato P7?

    no, there website and sales staff do not know of these vintage tyres, when I was at the last porsche parade, I mentioned to the Pirelli staff that I had just fitted the Cinturato a67 in 165hr/15 they responded that I was lucky to find them.

    Michelin still makes their XWX --- + in the correct size . . . for my car, anyway

    But --- as good as the Michelins look? . . .


    . . . Pirelli is what's on my Kardex



    So, thank you for that bit o' news, Mr Cawley

    Hi

    Yes Michelin do make the 185/70VR15 XWX you can buy them here https://www.borrani.com/michelin-tyr...helin-xwx.html or http://www.longstonetyres.co.uk/page...helin-xwx.html there is no doubt that the Michelin is also an excellent tyre, and for that period of 911 where they were fitted front and year that is a great option, but sadly Michelin don't make a 215/60VR15, and that is where for now the Avon CR6ZZ though it has a carcass that is developed to go with cars like these it doesn't look quite right and it is a road race compound which diminishes it's longevity.

    My apologies for the gratuitous advertising, but this is an old advert we published which shows you some of the other Michelin Porsche tyres that we currently sell. these tyres could well be of interest to you https://www.borrani.com/michelin-tyres.html?cat=1224 they are 16" tyres for the 964, 993 & 930

    There is a slight discussion about P7. i don't want to get your hopes up, because it might not happen. i would say it definitely won't happen this year, there are other projects in progress. but:-
    what sizes would you be interested in?
    what cars are they for?
    can you give me rough numbers of how many of these cars are still around?

    Big tyre manufacturers find that dealing with old tyres themselves doesn't necessarily work out, and it is best dealt with by specialist Nerds like us at Longstone Tyres, where we understand more about your cars.

    Currently i am very involved with Pirelli developing a classic tyre range. I would suggest that if you contact a specialist tyre dealer for cars like this you are more likely to get the full information. When it comes to Michelin or Pirelli we generally have a reasonable hold on what is going on.

    Regarding the P7, it would be great to have it in 225/50 16. This is for the original 928s, that will be 40 years old next year. This was the original tyre for them, but any 928 from 1978 to 1985 model year could have it.

    205/55 R16
    225/50 R16

    911 Turbo 1977-mid-80's
    911SC 1978-mid-80s

    They switched to Dunlop in the mid-80's. I think the Lamborghini Countach used the 225/50 R16 on the front wheels.

    Don't know how many SC's are still out there but I'd say plenty with high production numbers and full rust prevention.

    Hi Dougal

    That is good news. We have met and spoken about this tyre.

    I'm the guy from the F1 team / Motorsport Industry Association who bent your (and other folks) ears at the Pirelli /Longstone stand at the Birmingham Autosport international Motorsport show a year or two ago -- lobbying to reintroduce this CN36 215 60 15 Pirelli tyre.

    IIRC the RS was the first to have different size front and rears and initially its supply to Porsche exclusive to Pirelli, so good move from a historic milestone perspective. Available on that model from Porsche model year 1973 so presumably available from late summer 1972.

    I actually still have a couple of old German-made 215 60 15 CN 36. An old version that require inner tubes like were fitted to the RS when new, as documented in excerpt from an early 1973 RS road-test article shown at bottom of this post.

    Altough old they're still visually excellent shape and have decent tread do I've kept this pair for "show", (not "go" obviously) because nothing else looks quite right on early RS with 6 and 7s.

    This is a Pirell advert photo from June 1973 in a UK magazine, the tyre is labelled Roadstar and refers only to 70 profile -- so not sure why advert call them that unless they are different from CN36? Sprinzel had a Porsche dealership (Denham) UK listed in the Porsche factory service directory maroon and silver book in 1973.

    Front CN36 have not been a problem to find and I have a number of period ones plus they are available but these rears in the 215 60 15 size proverbial hens teeth, so I'm told.

    It would be great to get some new -- correct and usable for an RS. The ones I have bear the old three digit date code and given they are old school tube type I've wondered if the 404 is week 40 of either 1974 or 1984. Maybe Dougal can tell me?

    There is no triangle signifying 90s, which I understand was used the decade before the move to 4 digit age code. Also I've owned car since before 94 so don't see how this pair here could be from week 40 1994 but it and IIRC they came with the car among the collection of spares but not actually on the car / wheels. It was a long time ago so not totally certain. Here and also at bottom are some pictures for anyone interested to see markings of these old 215 60 15 CN36 Pirellis:

    Be interesting where any new ones made and what side markings appear.

    Brian (Fryardds) once kindly sent some info about my car. He pointed out had handwritten "Dunlop" hand annotated by someone at factory ( Jurgen Barth maybe?) alongside my vin # entry, but the car's spare is an unused wheel and 185 70 15 CN36 (all pimples intact across full tread) on the 6 x15 12/72 dated Fuchs. We never solved that mystery as my car would have probaly pre dated Dunlops being option on RS unless it was some sort of trial? Series Fuchs and full size spare are original to the British market RS and Pirelli brand tallies with a factory confirmation letter that I trust more than the COA, despite the latter saying Pirelli too.

    I also have pair of 215 60 15 correct specificaton or RS Dunlops too, but much prefer the Pirelli CN 36 tread pattern which seem right for first series RS. I have heard they were better quality from people who remember the choice with less failures when new. Matters not for show only tyres of course. The Dunlops are tubeless and dated similarly week 42 of year 4 as shown in photo below.

    None of these old tyres are fitted to car or wheels, just stored carefully to preserve them.
