    I have the original wheels from the car (can't remember the model off the top of my head) in the shed with el-cheapo rubber on them - potentially, I could swap the Pirelli on to them and then whack them on ebay I suppose. Worth a few quid cash to whoever fits the new tyres to swap them over for me maybe?

    I'd be severely unhappy if I bought new rubber and it still did it though.

    Not sure - there is a guy just up the road with a diesel XJ, but I have never spoken with him (this being the SW edge of London, neighbourhoods are not like those I am used to up north!) so I think it is a bit of a stretch to ask to borrow his wheels

    I even wondered about chucking some cheap Chinese winter rubber on the spare set of wheels, but that would almost certainly be a waste.

    I’ve got 285/30 Dunlops (6mm, 32Psi) on a 9.5x20 and I spin the rears easily in damp conditions. Rarely happens in the dry but is possible.

    My apologies in advance if I upset anyone here.....

    I have an X350 XJR. I live in the country and the car gets Driven with a capital "D" if you get my meaning. I would say that in standard form, the car is way, way over-tyred and should never struggle for grip under any circumstances. Indeed, I use mine quite a bit for teaching new track-day drivers and it never struggles there, either - even when dispatching 911s or M3s.

    This morning was really icy and I'm down to about 2mm on my front tyres - but no traction issues either, except possible when I had all four wheels airborne (happens quite a bit where I am).

    So, that leaves two possible issues:-

    Driver re-calibration needed, or

    something wrong with the vehicle

    If I'm honest, I'd favour the first one, but for vehicle checks, you'd really need go no further than a proper 4-wheel alignment to tease out any issues

    Sorry

    In my case, it is me stamping on the throttle pedal, trying to leverage a gap at a roundabout, for example.

    So yes, the Driver is the cause - but still surprised how quick the tyres are to light up.

    Now't to be sorry for

    I can fully accept that it happens when I am being that bit more enthusiastic - no problems this morning when it was icy, but then I was being that little bit less enthusiastic - and thereby could be as much down to me as anything else. I was just a little surprised that it happened quite so readily given that I wasn't exactly chucking it about or doing a racing start. I need to get my tame mechanic to have a look at it for me, but I would be surprised if there was anything seriously amiss with the suspension as he only put a year's MOT on it for me five or six weeks ago. Whilst he isn't the sort to go finding loads of faults to generate work, he also doesn't muck about if there is something needing done.

    I will get it checked and go from there.

    I had Pirellis on my 3.0 many years ago, awful in the wet, granted they were the P6000 premium ditchfinders...

    The Rainsport 3 on my Super V8 seem perfectly fine in the current weather - no issues so far. Obviously, pulling out of junctions with to much throttle will result in wheelspin, but fine under normal driving.

    OK, there is definitely something not right this morning on this roundabout https://www.google.co.uk/maps/@51.43...2!8i6656?hl=en (8.30 or thereabouts in heavy traffic), I had the back end slide out on me; nothing horrendous, but enough and enough that it simply should not have happened. Whilst Mrs C is not a driver, she even commented that I hadn't pulled away onto the roundabout all that quickly (I couldn't even if I had wanted to, as there was traffic in front of me). Traction control light gave a few flicks on and off, so it had noticed the loss of traction, although I am not too sure just how much it intervened. So, I am going to have to be a extra careful until I can get it looked at, but to me it still feels like tyres.

    In other news, it seems that it is not only Pirelli's tyres that have turned a bit sh*t - https://www.dailymail.co.uk/tvshowbi...20-spread.html

    Does sound like the tyres have hardened/gone off, unusual if only a couple of years old. Is it just the rears or do the fronts let go early in the corners?
    Alternatively it could just be Pirellis' don't perform well when near freezing, it is warming up in the South East over the next few days it'll be interesting to see if they improve.
    '07 Sovereign X358 in Black with 20" wheels and cream interior. Couldn't resist the glorious V8 although a diesel would have made more sense
    Bought in Oct '18 as an everyday car needing a bit of TLC which it will get over the next few months.

    High days and holidays car is a TVR Tuscan which has had a recent chassis off refurb and rebuild and now drives better than ever with new bushes and springs throughout and rebuilt power steering, diff, gearbox and shocks.
