I went with the White Walls to hide the P4000 .......................Just kidding. Yes the big P4000 is not great. Funny the new P4 has a very small P4. But that is not a V rated tire and more for a mini van. I would be happy to look your car over before the judging and give you some input. the nice thing is that we really aren't judged against one another so much as against the 'points'. As many as deserve a pltinum can get it. Of course they only give one gold and one silver. Can be cars that are 94.75 and 94.5. the next car at 92.25 is left out in the cold. And yes start a thread so we know who is going and who aint.

Hi Mark,

I may be a little late to chime in but I run Michelins XVS. I really like the ride and the vintage look.

BTW, I did have the XWX on my car before. The tires were rock hard. They were installed before I bought my car so I know they were getting old. So I doubt it would be a good representation of the tires.

Good luck at FCA event. sorry I won't be able to make it.

Hope to see you at Cavallino this year.

I know the feeling. As a matter of coincidence, I have two black
leather Natuzzi couches from Italy. When lifting up on the cushions
I noticed the black rubber straps supporting them. I was amazed
when upon close inspection, the straps yielded the word "Pirelli"
on them. At that point, I felt as if a hand had reached down
from the heavens providing solace and comfort. It was a grateful
moment...

I just got an email to the 330 GT Registry from Longstone Tyres in the UK. Never dealt with them, but I thought that some members might be interested:

I’m contacting you from Longstone Tyres. We are at present in cahoots with Pirelli. They are reproducing for us the original equipment tyre for your car [330 GT]. The 205VR15 Pirelli Cinturato CN72. Presently we encouraging your members to fit the Michelin XWX tyre which we offer free carriage on. Could we arrange a link with your web site? Do you run a club magazine?

For what it's worth, I got caught in a rainstorm 2 years ago (the joke locally is that farmers hope I take my car out for a spin). I was riding on wires and XWX's with almost new tread. Running about 70MPH, the car started aquaplaning with significant losss of direction, I almost wound up in a spin, and spent the next 1/2 hour under a bridge abutment waiting for the rain to subside. I regularly charge around corners in the dry with this set-up and no problem....but hit water and all hell breaks loose. Take a look at the tread pattern. I am no expert, but there is not much on an XWX for sluicing away water. I just bought a set of used Cromodoras (easy cleaning saves fingers) for track and general use and mounted P4000's. Naturally, I picked up the car and bingo, it rained. No issues at all, stayed hard and fast to the chosen driving line at speeds approaching 85MPH. For me, XWX's for show, P4000 for driving.

I just installed Vredestein Sprint Classic 205/70VR15 tires on my 365 GT 2+2. They have the right profile and seem to ride softer than the long-in-the-tooth XWXs that I took off. I don't know from squat about handling but they don't seem to "squirm" in the corners like the XWXs did. I'll know more after I've driven them to and from Elkhart Lake in July (4,000 km round trip).

As an update I do like the ride and capabilities of the P4000. I was not happy with the look though and mounted a set of Vredesteins (or however you spell it) to another set of wheels. They run and handle nice and have the right look. Two sets now oh well.

Has any one who posted on this subject considered tire size,diameter, when considering which tires to purchase,or is this not an issue of concern?

Yes. I can't find my notes at the moment, but if I remember correctly, the Vredestein 205/70VR15 rolling radius is about 1/4 inch less than the 215/70VR15 XWX, meaning the car will sit about 1/4 inch lower with the Vredesteins. I can't see the difference with them on the car.

How you would describe the handling compared to the Pirelli P4000's?

Has anyone been able to try the newly minted Pirelli Cinturato tires mentioned in the thread? I foudn this link for a source for them:http://www.longstonetyres.co.uk/prod...-Cinturato.php No mention of price, but a dozen donuts says they will not be cheap.

Thanks.

I am concerned that the new CN72, about to be produced thru Longstone, will be the wrong period size and done so to compete with Vredestein and XWX which are also the wrong period size for pre 1969, but fine on cars produced after 1969. This wrong size has to do with the series ratio sizes like 78 series, 75 series, 70 series, and the like. To my research, the CN72 was a very specific 78 or 75 series tire, i actually dont remember right now. I will be very impressed if Pirelli and Longstone actually get this 205VR15 CN72 correct.
I am sure you have seen this data before from the March 1970 Pirelli Cinturato Pocket Guide (Tenth Edition) but it is worth posting to this thread.

The last page of the Pocket guide gives dimensional data for the CN72 series. The dimension page only addresses the all CN72 as HR rated tires, but i am confident everyone has already measured enough period 205VR15 CN72 to realize they are the same size as 205HR15.

A tire that is 27.67" in diameter is quite large, but being a tall skinny tire, it is not overly heavy looking. The entire design of the wheel wells/wheel openings on these 60's era Ferrari cars (and Lamborghini cars) are based on this Pirelli CN72 tire series diameter. It would be so pleasing to have the wheel wells filled with the correct CN72's.

Just for the record, here is the cover on the 100 page Pocket Guide.
The size of the folded, red booklet is 73mm x 120mm.
I bought it off Ebay years ago.
It came with a white plastic, telescoping, Pirelli tread depth gage.
Anyone have further documentation or period advertising for CN72 Pirelli?
