why so hard to get sets of tyres 245/45/18 and 255/45/18
ive always gone for part worns in the past but theyre like gold dust.
also is there any way i can check to see if the engine has had the plastic timing chain bits changed, silly question i suppose... do they always give out also if the cars had a full main dealer service past would they have done this as matter of course as the mileage creeps over the 100k
thanks all

Hi 400,
Pirelli's for that size, which were the car's OE, have been in short supply for a while now. However there are more makes now available for this car - Continental, Dunlop and Toyo do them in the 18". A lot have reported an improvement in tramlining from the original Pirelli's when changing brands.
Regarding the secondary tensioners, the only way to check is to remove the top covers and have a physical look. Jaguar did not do this as a matter of course - that would be an addmission of a design fault ;-) If you have just got your car and plan to keep it, get them checked and have a back up plan to change them if they are found to be worn - plan to do the primary tensioners while you are at it, as they wore out too. That will need the front of the engine off so is quite a big job so plan for about £1000 at a independent specialist ... but a failure will cost you a new engine
Try and find out the service history from previous stamps. They wont give previous owners details but will usually tell you if any major work has been carried out.
Good luck and enjoy - these are lovely cars to be in

so i would say imperative you check them out,
thanks all.. the car is over the 150k and engine is quite from start up and when warm still quite so will look into as soon as poss shes a late 97 but runs and drives like a 07 really tidy too.. no rattles from under the bonnet, will try and get hold of the owners as on the v5 for a chat...cheers
Take the right bank cam cover off (easier than the left one) and see what secondary tensioners are fitted. If they are cream or brown plastic bodied ones then change them for the metal bodied type asap.
Whilst you have the cover off, have a really thorough look at the rest of the timing gear. Specifically you want to see and feel tight chains, no evidence of any bright spots or rough edges on the chains and sprockets and no signs of any heavy grooving on the slippers and guides. Shine a troch right down into the timing case and have a really good nose about. If all's OK and the engine internals are bright and clean, not gunged up with heavy brown or black tarry deposits chances are all you'll need to do is get the latest type of secondary tensioners fitted.
Even at a high mileage, providing the car has been maintained well and not overheated there's a good chance the chains themselves, along with the guides and primary tensioners will be OK. If you're not sure or think you may have a borderline wear problem then IMO get expert advice on your specific engine rather than my generalisations before you rush out and have the whole lot changed - it'll save you a fortune.
