[concours] Introduction and question on tires

Hi,

I’ve received the Concour dig. for a while, and thought I’d introduce myself
although I’ve been with the Jag-lovers since the very start.

A member of the Norwegian Jaguar Club since 1991, and JEC since '93-ish, I
have been a concours judge since 1994, first for pre-68 saloons. After our
club decided to split post-68 saloons into Series I + II and Series
III/XJ40/X300, I’ve judged the latter (entering a 1972 Series I Jaguar
myself).

I am also a self-proclaimed spokesman for elevating the standards of our
club’s concours as such, and have therefore followed your discussions with
interest.

Question regarding tires: As for my own entry, our car (Series I Jaguar XJ6
4.2 litre SWB 1972) was originally equipped with the bespoke Dunlop SP Sport
E70VR15; the original tires that were actually designed in a joint effort by
Jaguar Cars and Dunlop. (The spare tire is still virtually unused, and
resides in the spare wheel well.)

The original tires were long gone when we bought the car so, wanting to
stick to Dunlop SPs because of the history, we first moved to Dunlop SP
Sport D7 (215/70/15), which was the nearest I could come to E70VR15 after
carefully measuring the spare wheel. We had some discussions on the tire
size, but managed ok. A couple of years back it was time to re-shoe again.
This time, Dunlop had replaced the D7s with ‘SP Sport D2000’ which, to
resemble the previous, were recommended in dim. 225/60/15. Now the judges
aren’t in the slightest doubt; I lose points every time.

What are the criteria for keeping your points on tires on the “International
Scene”?

Thank you!

Best regards,

Baard,
The tire judging rules published by Jaguar Clubs of North America leave
much to be desired. However, they contain one (slightly dated) statement
in Appendix B, Page 5, which may be of help.

“During 1972-1974 the tire industry experienced near-chaos as it changed
industry standards and nomenclature. The original equipment Dunlop
ER70x15VR used to be a “205” tire. After the industry standards changed
in the 1970s, the ER70x15VR became a “185” tire, and later went out of
production. So, if you you ask tire dealer to order an equivalent tire
to the OEWM ER70xVR15, his records will indicate a post-revision spec.
of “185” which is the WRONG SIZE for these model Jaguars. Correct
equivalent equipment today: Dunlop 205/70xVR15 SP Sport Super D7;
Pirelli 205xVR15 P5; Michelin 205/70xVR15 XWX.”

Michelin 205/70xVR15 XWXT is still available as are Dunlop “Elite”
215/70xVR15s.

Good luck,
Dick Cavicke

When I judge in the concours, I look for the correct size tire. The
rules don’t allow point deductions for the manufacture of the tires. If
you are a purist, Coker Tire here in the USA makes just about every tire
for vintage cars. The tires for my 59 Mk IX cost about $130.00 each.

Dear Dick:
My’70 OTS E-Type is in need of tires. I want to be as correct and original
as possible. Can you advise me on the correct size and mfg. to purchase. I
am also thinking of replacing the factory Turbo Disk wheels with correct wire
wheels. Any suggestions on tires/wheels would be much appreciated.
Regards, Tom
