    I'm thinking of fitting 9" rims on the rear of the Daytona, for aesthetic reasons. One question though is what tyre size and brand to go for?

    The car has Pirelli P4000's 215/70's all round. Has anyone fitted these (with I assume a different size) on a 9" rim, and did they rub on the arches?

    There is the obvious Michelin XWX choice as well but are there any other brands to consider?

    This is purely for road use.

    Thanks in advance.

    My C4 had P4000 all round when I bought it, I only realised how terrible they were after I fitted XWXs (sourced from Longstone). The ride and road holding even at moderate speeds was so much better and they just look right. On a similar note, I recently fitted 9' wheels to the rear, the appropriate tyre size is 225/70 and I love the new look ;)

    More pic's:-
    Eurospares specials for the winter.
    Manged to get the price down a bit after a bit of haggling!
    No issues with rubbing Matt, although fitting the tyres was a bit more difficult, being such narrow tyres for wide wheels.
    They needed to use a tyre bead blaster, normally used on tractors, to get it on the beads, it needs to be blasted from the rear of the wheel!

    The Blaster looked like this :- BEAD SEATER 10 Gallon Tire Seating Blaster Inflator ATV Tractor Truck 145 PSI : Amazon.com : Automotive
    Also try Vintage tyres, they where cheaper than Longstone, but ask when the tyres were made, as they may have been on the shelf a long time.

    Problem with the Eurospares repros is that the tyre valve is in the wrong spot, wonder why they did that?? Perhaps this made the fitment more difficult (my 9" wheels are factory and had no problems fitting the tyres)

    Hi Greg.
    I don't think that was a problem, it was that new tyres are about 4inch narrower than the wheels, once the tyres have been fitted, if they need to be refitted then there is no problem as they have stretched to the right width.
    Matt. Love the blue C4,[ do you know the colour]?
    Are the pepper pots 9" and did your Dad need to have the rear arch's modified to fit them as i believe is necessary for the 9" alloys to fit a C4?

    Hi, the tyres I had fitted to the 9" wheels were brand new out of the box and went on without any fuss or any need for stretching and this was at a local non specialist tyre place, so not sure why it was a problem in your case. I haven't had my rear arches modified to fit the 9" wheels. It's a close fit, but no rubbing....Yet :)

    Hi Grant,

    No they are a standard 7.5" Queen Mary wheel and fitted straight on with no mods.

    As to the colour I'm not sure, the advert from DK where Dad brought it said azurro Metallicazzo (sp?) but don't see that colour in and of Ferrari's colour charts.

    That's not the only problem I noticed, when I looked at the picture.

    Never use any kind of rubber valves on a car that can do speeds above 250 km/h!
    This is dangerous at high speed and not original.

    I have 9" rims on the rear of my 365 Boxer and had problems with tires until I found Avons. I use 215/70R15 for the front and 275/55R15 in the rear. Of course, the Avons clearly don't look the same as original spec tires, and you will need another set of wheels and tires if you want to do judged shows, but if your principal concern is driving, I can tell you that the Boxer drives wonderfully with the Avons and vastly better than with the Michelins that were on the car (although they were 10 years old and hard). The Avons are street legal, quite sticky, and are priced very reasonably.

    Interesting are your tyres Avon CR6ZZ's what sort of life expectancy do you get in respect of mileage with those?

    Hi

    Comparing anything to a tyre that was 10 years old isn't going to be fair. when a tyre is 10 years old it is knackered. specially if you are in a hot country. i still think the Michelin is the most suitable set up https://www.longstonetyres.co.uk/classic-car-tyres/ferrari/512bb.html

    the other option would be Pirelli Cinturato CN12 https://www.longstonetyres.co.uk/pirelli-collezione/cinturato-cn12.html these are a period road tyre, so a more suitable long term set up than the racing rubber of the CR6ZZ. the CN12 was what the Lamborghini Muira fitted when they moved onto the SV model. https://www.longstonetyres.co.uk/classic-car-tyres/lamborghini/miura.html . However i guess it is fair to say that the later 512BBi did go for fatter tyres 240/55R415 TRX https://www.longstonetyres.co.uk/catalog/product/view/id/5522/category/6434 so maybe that wider CN12 would work.

    Don't get me wrong i am a big fan of the CR6ZZ https://www.longstonetyres.co.uk/vintage-tyres/avon-cr6zz.html they are great. And if you take of 10 year old tyres and fit new racing rubber i would imagine the contrast would be staggering. But racing rubber is not developed to be used the way you want to use it on a road car. the compound will deteriorate quicker. A race tyre like that is only really built with the expectations of going through a few heat cycles on a race track then be replaced.

    Hi Timo.
    They were bought from Ferrari UK who still sell them, as far as I know.

    I fitted them with some ply wood with the correct size hole in and them a box spanner/ socket that fits an emersion tank element that goes over the centre perfectly and hit that with a lump hammer used on its side so you can hit both sides of the socket at once

    Have a great Christmas

    Grant, Great Christmas & Happy Holidays to you too and everyone else here in Vintage section.

    Sorry, but my question was about the material of the circular (shiny) trim rings that cover wheel hub mounting hardware (behind the knock-off nut in your picture).
    Are they those readily available reproductions made of polished Stainless Steel or are they chrome plated mild steel (like OEM) ?
    Just wondering because their appearance (in photos) seem to suggest Stainless.

    Yes they are stainless which is all that is available now as far as I know, they are fine for concours as they are a genuine replacement part from Ferrari.

    They are also available here http://www.superformance.co.uk/v12/wheels.html

    I thought they looked Stainless in your photos, thanks for confirming.
    I ordered couple of sets few years ago, but returned all after seeing the material used being Stainless with somewhat questionable quality of prep & polish, which would’ve taken nearly same effort to refinish than re-chroming original mild steel ones.
