I run 245-50x 15" tires on 8" Campys in front with no spring spacers and a lowered front end. (295-50x 15" in back on 10" Campys & the car's balance is exceptional). The contact areas- all show up only in full lock turns- are very minimal and I was able to correct them all with a ball peen hammer in less than an hr. This was in 2002. You may find the left side tire has issues while the right side does not (except for the wiper motor shield).

A 245 is about the max width tire a narrow body Pantera can run, regardless of 15, 16, 17 etc wheel. IMHO, the larger footprint of a 245 and resulting traction & braking improvement is worth an hour's fiddling.

rs1, Jack and Garth, thank you.  I currently have little-used, but over-aged P225/50R-15 and P295/50R-15 Dunlops mounted on 8" and 10" aftermarket BBS-style wheels on my 1974 GTS that fit well, but Avon does not make a P225/50R-15 (or a P245/50R-15) CR6ZZ tire, and the diameter of their P225/60R-15 is 25.7" vs the approximately 23.9" diameter of P225/R50-15's.  I am planning to buy a set of 15-8" and 15-10" Campagnola reproduction wheels and would like to buy a new set of tires from a single manufacturer to fit them, but as rs1 indicates, my primary concern is what interference or other problems the taller tires may create.

It appears that a number of owners like me who want to keep their OEM wheels are having to install front and rear tires from different manufacturers.  I have read that other than aesthetics, as long as they're all radials and you don't mix them on the same axle, this doesn't create a significant problem with handling or premature wear of suspension components.

Comments?  Has anyone else tried the Avon CR6ZZ's in these sizes?

Here's a pic of my car with 205-60x15 tires on the front and 305-50x15 on the rear.  The 205-60x15 tires have a diameter of 24.7", so only 0.8" larger than the 225-50x15 tires, which is negligible.  And FWIW, I had no rubbing issues with the 205-60x15 tires on 7" Campys up front.


ADDITIONAL NOTE: This pic was taken with the original spring spacers still installed on the car.

there has been a development.


i know i said it would take a long time to get these 285/50 -15 P7's made, but i didn't plan on Covid19! I have had this coment from Pirelli

"285/50R15 (104Y) P7          Building proto at the moment. Final product expected towards the end of the year"

Can i just say, that i am not by any means garunteeing that they will be ready at the end of the year. There are all sorts of things that can get in the way of having them by then. Basically all the production of our tyres is very difficult at present because so many tyre factories got shut down to isolate, and you can imagine, the little piffling batches i ask them to make are not as high priority of the Likes of Porsche or Ford asking for production space. However i will still keep on fighting for production.

Incidentally i am out of the 345/35-15 P7 for now, but i beleive there will be some in the States at Lucas classic Tyres


We have just had a new delivery of the 345/35R15 P7 tyres.

Date code 3820. doesn't get much  better than that.

We still have the 285/40-15 P7 in stock

i am still chasing the 285/50R15 P7. I have been told we should have them by the end of the year. I do give them a regualr nag just to keep the ball rolling. i must admit to being a little bit skeptical about them, because there have been several factory shut downs etc. However all being well we should have them soonish


I now beleive the 285/50R15 P7 has actually been produced. I also beleive they are currently in a lorry on their way to Longstone Tyres! which is great news.

They will be on here soon

Of course i will post on here again when they get here. How exciting, but blimey iot has taken some time, but the Pandemic has cost us an extra 2 years, and i do have other projects in with Pirelli that have just been put on the back burner so it will be great to get these.

i am relatively confident i will be able to keep the price sensible.


Ok we do have the first delivery.

These tyres are now being shipped out to the various intenational distriutors of the Pirelli Collezione range who can be found on here

(you may also like the very cool period marketing film for the Cinturato. When did you last see a truck driver drinking red wine out of a magnum and smoking fag all while driving in an advert. I think i would have liked the 1960s with all those mini skirts)

285-50-15 P7 first delivery 1622 

Back to business.

Many of these international dealers will not have received these tyres quite yet, however they are on their way. I would ask you to respect the dealer network, it will save us money and it is a far greener way of distributing these tyres than for us flying them all over the world.

I truly hope you guy are as happy about these tyres as the Lamborghini Countach fraternity were when we got the 345/35R15 P7 made again. I'm not for a minute denying i am in this to make a living, but it is great when our customer are really happy, like a truly hope you guys will be.

Hi Team.

Might i suggest anyone who is thinking of doing some tyre shopping in the near future, get stuck in and do it now.

The Pirelli P7 range for your cars are incredibley good value. I was amazed when i managed to ge them to market at such a good price. yes i know it amounts to a large credit card bill but for such rare weird obsolete tyres that don't fit anything else the prices are amazingly good. for instance go and look what you will pay for a P-Zero 345/35R15

When you go looking for a comparison for the 285/50R15 P7, you can't find one, because nobody else makes it, because no cars fit 285/50-15. The closest you will get is only an Avon Race tyre. which are similarly priced. What they aren't is a incredibly high performance bespoke road tyre made by one of the worlds best tyre manufacturers specially for you!

Anyway. i can wobble on about what good value these tyres are and how incredible it is that i managed to get this tyre made specially for you guy; by Pirelli no less. The fact of the matter is the reason behind this post is to let you know that the price will be going up early next year or before, so grab them while they are such good value.

I'm afraid price rises are something we are going to have to become accustomed to.

The garage is too narrow for a good side shot, but I took the car outside briefly yesterday and took some winter pics. My other set of tires are 335/35zr17 and they have the exact diameter as the 285s, so I didn´t have to change anything in regards to ride height. The color is Monza Rosso, the mobile phone seems to pick up all kinds of colors though - sometimes it looks pink or towards orange. It´s really more of a typical Ferrari red (see 2nd pic). 20221203_144825306160299_618249079750055_3424116221583771160_n

They look great. What i am really looking forward to is the influx of people posting how much nicer the car is to drive now it on proper tyres.

I bet particularly you guys who have taken off tall wheels with modern tyres are in fro a real treat.

I dont suppose there is a chance of getting hold of a period picture of the side wall of one of these tyres. I would like to see what was written on the side wall (yes i am a nerd)

I also beleive in the States you guys had to have a sticker in  the window telling what the tyre size was and the tyre pressures. i love stuff like that for this web page.

One option for our cars may soon disappear, Avon Motorsport (now owned by Cooper tires brand) is closing their factory in Melksham, UK at end of 2023 which I believe manufactures the CR6ZZ tires, no confirmation if any of the tires produced in Melksham will be shifted to an alternate site.

Historic racers are already hoarding slick tires to try and counteract the impact.

I recently bought two Pirelli P7 tires for the front in 225 50 15 and I'm surprised to see two speed ratings written on the tires.

A first in large letter 205/50 VR15

and another inscription, smaller 225/50 ZR15 (91Y).

My supplier tells me that these are "Y" but is unable to tell me why there are two contradictory inscriptions.

What do you think about that?
Did Pirelli keep the large lettering for the original look?

@rene4406 "Did Pirelli keep the large lettering for the original look?"

Yes - here´s a quote from the Longstone website:

"The tyres were originally named 285/50VR15 P7 however they are actually homologated as a 285/50 R15 104Y, as they do actually qualify for the higher Y speed rating. This detail is written on the side wall in less conspicuous smaller writing to keep the tyres looking as they did back in the day."


It is a bit complex, because to make it more complicated, throughout the original production of the tyre the script on the sidewall would have changed, as wopuld the speed rating. the V speed rating means the tyre is capable of speeds above 149 mph. but since then they have develoiped more speed ratings (including the Y in this case)

the small script on the side needs to be there to make sure these tyres cover the current tyre regulations.

have you fitted them yet? is the handling improved compared to what you had on before?
