What size is the spare for the 2004 XJR 18 or 19? My OEM regular tire size is 19, but spare is 18, is that normal?

Thanks,

Keith

 

Is it a space saver, or a full size? If full size it should be the same wheel/size as on the car, but it can be different and still function as a spare. If space saver (or full size, for that matter), the overall tire diameter must come close to the overall rolling diameter of the wheels on the car. The rim sizes can vary, yet still accomplish this.

Regardless of the rim sizes, if the rolling diameters are different by more than 15% the ABS will interpret that as wheel slip.

 

I should check to see if my xjr has a different sized spare. It should be the same size, only the 20" had the space saver, i thought

 

I should have said rolling circumference, not rolling diameter...Doh!! See kids, this is why you should not drop out of HS in your sophomore year!

Budsang1, yes, you'd be a good check for Kfishlock since I don't have a spare XJR in my garage at the moment!...but I surely wish I did!

 

My 04 has a full size spair. It's a fifth wheel and I have 19" on her.

 

yep, i checked this morning, full size 19" fifth wheel in the trunk as well

 

What about uni-directional tyres ? A full size wheel with one of these on can only be fitted on one side of the car. Can you get bi-directional in the large sized used by Jaguar. On my Rover 75 full size spare I specifically fitted a bi-directional, (also a mid-range tyre to save money !).

 

18 inch space saver with 20 inch wheels. I have the sepangs. I took out the space saver and put a full size sepang in boot. I dont want to drive on a orange space saver!!
(If i ever flat)

If your car has the CZC 17279 "custom" 19" wheels, I've got a near perfect one for sale. This wheel came standard on some 04 XJRs.
