yes - one of the p4000s needs to be replaced. only about 8k miles on the set - so tread wear is not great. but can't find a p4000. or many other options for this size.
did find 4 225/65r 15 p4000s but they are sold as used - never used - so dry rot is a concern. and they are almost full retails price.

there do not seem to be many tires out there with the appropriate load and speed rating in 15" rims.

so - what size and brand/model tires are folks using on their xjss?

is the more expensive p600 the only option?

If you have loads and loads of spare time (heh he...who does?) you probably *could* find a single P4000 somewhere. There's gotta be some tire store...somewhere....that has one sitting around collecting dust. The tire industry surely has some means of networking.....if you can find someone on the inside willing to work with you.

But on to easier, faster solutions.......

If you disregard speed ratings you'll be able to find many choices in either the 215/70 or 235/60 size with an adequate *load* rating. If you don't plan on 150 mph driving you'll be fine....although you'll almost certainly lose some crispness in the steering/cornering department. If your driving style can be described as "crusing along" you might not even notice or care if the steering/cornering isn't as sharp.

You can also consider using a 225/60 tire. There are more to choose from in this size. Last time I checked there were several manufacturers offering a V-rated 225/60x15. You could look at 215/65s as well.

Or....move up to 16" wheels. Jaguar used a variety of 16" wheels on the XJS and other models.

I'm not sure if I understand the question. Are you wanting to replace one tire? One of the P4000s ?

my 89 xjs convertible has Pirelli P4000 215/70R15s on honeycomb wheels.
tirerack.com lists both 235/60R15 and 215/70R15 as OEM.
my spare (probably original base on the aged look of the rubber) is 235/60R15.

i need to replace one - and of course the P4000 seems to be discontinued.

what to do....

Art why not move this to the general discussion forum--let's see if there is any interest or help?

Submitted by silver007@shaw.ca on Tue, 05/25/2010 - 21:04

The answer to one problem would be to simply list them the same way as class 16 got rubbed over and judge only on condition....... and score them out of ten, not hard to figure that out. me thinks. start knocking. ( please ).
Best Wishes. Art

Art glad they are--hope you did not mind me stealing one of your logos for them. As far as the Dart archives --who knows--I think you have an excellent proposal so why not make it formally--gather some data and contact the owners (I asume they have some sort of organization) and put it forth to the members. There will need to be some guides written and training for few have seen the guts of a Dart. I still think you expect me to open the door and I assure you that is many levels above me--if the door is to be opened someone must knock. Best wishes.

George, the manuals look fine, I am sure there must be archived info on the Dart. surely... I believe all Daimler cars should be allowed to join and sort out the other criteria later........ I am sure there are enthusiasts out there who have the entire history. open the door and let them in.....fresh blood is good......

Submitted by SE98-32482CJ on Mon, 05/24/2010 - 22:36

Well Art I will say this as if it is not obivious--JCNA is a federation--JCNA does not decide the issues you have brought up the CLUBS decide at the AGM. I do not remember a motion ever being brought-not by me or you. If you feel that strongly why not organize the DART guys and present it. As far as a general statement that "Daimlers" are not allowed that is not factual. Daimlers are allowed in classes C9,10,11,12,and13 as well as the respective driven classes. That, of course that is because they were made under Jaguar and share common bodies and such. The problem with the Dart is it shares no common parts and one of the main issues if I remember what discussion was had was there were no guides nor anyone willing to write any-in other words you would have another class with no one qualified to evaluate it. So why not start a movement--heck I will help in any way I can---in the mean time I will try to work other things as asked to help the club--such as this tire issue--which is being worked on now--not 10 years from now--by the way how were the manuals in your MGJP?

Submitted by silver007@shaw.ca on Mon, 05/24/2010 - 21:21

it is for some for sure. lets let the guy's with Daimler's into our club, especially the SP250 many were made with Jaguar in command. I really object to these people being discriminated against............why are they not being allowed in anyway..... there was a big write up in the Jag Jrnl and then nothing happened in a positive manner for these owners........... they are a part of Jaguars history and should be able to join. it's not like they are lorries or such........

Steve and AI think if you look you will find the changes requested--I have not had time to but if you are interested possibly you will. Art it is not a battle---there are folks here that want to do!

Well Steve I thank you for sending that and I will forward it. Last evening I wrote the rule book editor and received a reply that the error you pointed out would be fixed along with a new look at all the data in appendix E. I am sorry if your work was not taken to heart but it will be now. Steve I do not know if it is evident but there is a new attitude and energy in the functional areas of the JCNA. Have you looked at the publications in the Shoppe now offered and the prices? Have you seen the other updates and changes in the web? While it may not be enough yet the desire is to offer expanded services to members at reasonable response times. Thanks again and it will be addressed.

I sent the info below as part of an e-mail to Gary Hagopian 10 years ago...nothing ever came of it as far as I know. I haven't checked what I wrote back then against the latest tire guide, but I'm sending it to you any way.
-------------------------------------------------------------------------------

You should be aware that there are some errors. Such as
1. For the 85-88 XJS-C: Wheels should be 6.5x15 Starfish. Also the '(Non-US)' note should be deleted

2. For the 1986-1990 XJ-S: wheels should be 6.5x15

3. For 1988 XJR-S Le Mans: wheels should be 7.5x15 JaguarSport 'Speedline', and tires are Pirelli 235/60VR-15 at all 4 corners.

4. For XJR-S model years 1989 through 1991: the wheels are the same JaguarSport 'Speedline', but 8x16 instead, using Dunlop D40-M2 225/50ZR-16 in front and the 245/55ZR-16 in the back (as erroneously listed for MY88).

5. For the 1991 XJ-S Classic Coupe: wheels should be 6.5x15

6. For the 1992 XJ-S: Wheels should be 6.5x15, and 1993 model year should be added

7. For 1993 XJR-S: the tire sizes are correct, but are not NCT60s, but rather Goodyear Eagle ZR's (aka 'Gatorbacks'). Also should add model year 1992

8. For 1994 XJ-S: Add 7x16 size for 5-spoke wheels on 94/P600 line. Also, Pirelli P4000 in 225/60ZR-16 on 7x16 5-spoke wheels were used on the conv't

9. For 1994 and 1995 XJ-S: wheels should not be listed as 'starfish', these are not the same as the 'starfish' wheels introduced with the HE model. Maybe should be called '5-spoke sport'?

Steve you are correct--we will need to inform Jaguar that their data has been corrected. THe Appendix is incorrect and no one has seen that for years--How about going through it and let the JCRC (or me) know if you find any others. I think the wheels are wrong for that car also in the appendix/ thanks for your help. I think they reported the 88 size and mixed it with the 89---but you will read his car is an 1898 model! Sorry could not resist.

Ron, if you're interested in a performance tire....and I don't know that you are....you'll find your choices very limited in the 235/60x15 size.

Going to a 225/60 will give you more choices.

Cheers

Incorrect.

OEM for an 89 convertible is 235/60-15, Pirelli P600

A 70 series is much too tall (almost 2 inches too tall).

Submitted by SE98-32482CJ on Sun, 05/23/2010 - 18:13

Ron if you go to the concours page here and look in Appendix B (Tires and sizes) you should find your car had 235-70VR 15 Pirelli tires. The information is also in your handbook and probaply the spare is original (normally never see the road). Good luck hope this helps.
