    I didn't mean for my quick post to be a review, I was just very disappointed and asking for opinions out there just to double check - maybe there are things that I can do on my end - like waiting for them to scrub in more, redo the alignment (even though it was fine before), rebalance the fronts for sure... just a bit frustrated after the $$$ spent and no positives other than looks - and even then I prefer the look of fatter rears honestly...

    Anyway I was running 31/33 as a "let's start there" pressure - not incredibly high... maybe it is too high for these ? I lowered to 28/31 and will experiment again... Mostly it's the front end that seems nervous but maybe the poor balancing contributed even before the vibration can be felt at 70+... All in all though I think I like 195/205 better on this car, feels a tad more planted.

    The gravel thing is amusing... My older tires used to drive over them without a fuss (little culvert at the end of the street), the CN36 must be very grippy or have the best tread to catch them, I'm spitting them out for 10 minutes literally, it's a cacophony of pings. I'm not a Pirelli hater but I've always had bad experiences with them on modern cars and prefer michelins, should have gone that road... They feel grippy - I'm puzzled - will play some more - I just wanted to be sure (if 5 of you have come out to say they sucked I'd know I screwed up...but nope).

    All softer tires pick up gravel. It's the trade off for grip.

    I run the CN36 on a RS with 215 in the back and on a 911t with 185 all around. I find them to be outstanding. I also run them with pressures at 28/30.
    I will buy these again when needed. Both cars track very well in windy conditions.

    Lars has the 185 x 70's CN36's all round on his 356 C sunroof coupe, his 73S .. and on his once owned '73 1/2T...

    None of these are particularly driven for performance but for comfort, roadability, smoothness, and quietness...

    I've driven all of these cars, but not with that new CN36 setup... But never heard any complaints from him...

    In fact he liked the feel so much on those cars that he then put'm on the '72 hot rod in the staggered size...

    Keep us posted bud...

    Interesting “original mounts” comment as starting assumption ... Weren’t other brand tyres like Michelin the original mounts on 6inch all round as fitted to TES?

    Were 185/7015 Pirelli cinturato CN36 ever fitted by the factory to 911TES on 6 inch rims all round during the long hood era? They were certainly factory fitted to 73 Carrera RS — in fact a small automotive historical first — RS having front / rear different width rims along with tyres of different width profiles on any road-car. Not aware of them being used by factory on TES before end of 73. Although owners may have done so as change of course ...

    Yes, some cars did come with Pirellis, and others (often Ts) came with Dunlops. From his car's thread, including a picture of the kardex.

    They looked cool but I found no confidents in them, and they got hard as rocks and unmanageable in a VERY short time.....

    So, I didn't know what to expect when I drove Lars' '72S hot rod pictured above with the 'new' CN36 setup...

    Well that was then... and now is now

    When I pushed them pretty hard up in our local hills I was VERY pleasantly surprised with their feel and dry weather traction … (no chance to try them in the wet)
    They only looked like the cool crappy tries 40 odd years ago... I LOVED THEM !!!

    I'm not sure whatsup with yours Greg.. But would, and have, recommended them to all who's thinking about it...

    Please keep us posted...

    Don’t know about Saab cn36 tyres or tyres on modified VW however the cn36 were tube type and of different construction as first used on Porsche 911. Several years layer the construction was changed (steel belt/nylon iirc ) and also cn36 went tubeless around 75 iirc. There is a thread on this somewhere which maybe worth noting attempting to draw any comparison of the reissued different tyres to the even then evolving “original fit” Pirelli produced back in the day (which several posts appear to be doing).

    Pirellii brand yes I don’t disagree ... But cn36 Cinturatos specifically though ? I am not a career tyre expert but I wasn’t convinced cn36 was used yet by factory in My 1970.

    Certainly would be interested to see hard evidence of cn36 (rather than other Pirelli) were on model year 70 TES or longhood ...as had always thought ( maybe incorrectly) cn36 was first used in RS even though it was first produced late sixties

    Coincidentally I had read longranger post with this Kardex today and that he seemed to assume Pirelli shown on his kardex was actually a cn36 om a 1970 model car ? I wondered since no designation beyond Pirelli if it was cn36 already from reading it earlier today hence I raise it here. Something to be queried because I noticed a similar assumption of cn36 original fit Had also kicked off this thread.

    Always open to learn from experts and specialists. Happy be corrected if I’m proven wrong with specific factory reference to cn36 being a factory fit during longhood.
