    Original tyres

    Hi

    I hope this is of interest to you:

    this web page is about the Pirelli P5 tyres

    https://www.longstonetyres.co.uk/pir...ezione/p5.html

    Pirelli have just produced the P5 again that was fitted as OE to the series 3 XJ cars. They make the sizes 205/70WR15 P5 and 215/70Wr15 P5 again (the 225/65R15 P5 has been around for about a year now)

    In 1977 Jag asked Pirelli to make them a tyre specially for their Luxury saloons the XJ6 & Xj12 and in 1979 Pirelli came up with their P5 which is now actually homologated by Jag with the J designation.

    and the price is really good.

    Good post Dougal, the prices are certainly better this time around. They were expensive the last time they were manufactured.

    Hi

    I note you are also a Jensen Interceptor fan. I recently discovered that the Interceptor also fitted Pirelli, but the earlier Cinturato CN12 https://www.longstonetyres.co.uk/pir...rato-cn12.html

    It’s funny, because Pirelli have spent so much time away from the classic car market that stuff gets forgotten. the perception has been that it was always Dunlop, which is not correct.

    And sadly now Dunlop don’t make any historic road tyres anymore. Which is a real shame.

    Hi,

    Thanks for sharing the info.

    I found this article from KWE cars very informative https://www.kwecars.com/jaguar-tech-...nd-xj-saloons/
    I bought the Falken tyres they recommend and then had them fitted to my "pepperpots", and they are working very well.

    Hmm i'm not so impressed by that. I don't like this bit "KWE takes the view that with the excellent suspension of the XJ it can easily tolerate a lower profile tyre to improve lateral stability in cornering without losing significant comfort"

    It seems driven by a desire to recomend a tyre that is relatively cheap and for sale from every tyre depot,instead of what is actually the best tyre. It was also probably written without them knowing that better tyres are available.

    60% of 225mm is somewhat less than 70% of 205mm, and lot less than 70% of 215mm

    The last thing i want to do with an XJ jag is have a smaller diamer tyre so it revs more at cruising speed, and why buy a luxury saloon and then compromise the comfort with a lower tyre.

    do you really need to "improve lateral stability in cornering" on your XJ. I certainly didn't. And it is not necessarily right either, a wider rim would be more likely to do that. They will not handle as well as a tyre that Jaguar themselves have tested for the car and stuck a J on the side wall.

    When this article was written they should really have recomended Pirelli CN12 or Michelin XWX.

    Do you want to save money on tyres compromising the ride, to then spend that money on petrol and servicing?
