I'm looking at a 2015 XK Special Edition Coupe. The front and rear tires sizes are different. I have a vague recollection that this is correct, but want to be sure. I've tried Google for the actual Jaguar specs, but just get a bunch of tire and wheel sellers and I can't tell if I'm looking at the factory specs or current aftermarket buzz.

So, what are the correct sizes, front and rear?

 

I found this:

Tires, P255/35ZR20 Summer Front & P285/30ZR20 Summer Rear Std - Std

Wheels, 19" Caravela - C44M

Wheels, 19". NOTE: Rim Width: 8.5" ; Wheels, 19". NOTE: Rim Width: 9.5" ; Includes 19" Tires. N/C - N/C

Wheels, 20" Alloy

Rim Width: 9" Std - Std

Wheels, 20" Kalimnos - C44P

Wheels, 20" Alloy. NOTE: Rim Width: 8.5" ; Wheels, 20" Alloy. NOTE: Rim Width: 9.5" $850$1,000

Wheels, 20" Venom - C46A

Wheels, 20" Alloy. NOTE: Rim Width: 9" ; Wheels, 20" Alloy. NOTE: Rim Width: 10" $850 - $1,000

 

Thanks, Sparkly.
Are you saying all of these tires were OE options on the car? It does look like the basic difference is wider rears, right?

 

Yes, staggered fitment is normal for both the XK and XKR of all years.

 

CeeJay, when did you change your name to Sparkly?

From a Jaguar handbook, official sizes:

18": 245/45ZR18 100Z + 275/40ZR18 103Z
19": 245/40ZR19 94Y + 275/35ZR19 96Y
20": 255/35ZR20 97Y + 285/30ZR20 99Y

18" wheels probably dropped in the last years.

 

You have the answer to the wheel question.

I'd also be questioning the "Special Edition" designation. X150 production ended in 2014 (2015MY) with the XK Signature and XK Dynamic R and XKR-S models.

From the Jaguar Press Release, "the XK Signature comes with 20’’ Kalimnos wheels as standard, with 20” Takoba wheels available as an option, while the XK Dynamic R has 20” Vortex diamond turned wheels – with distinctive Red painted brake calipers – and the option of 20” Vulcan Gloss Black lightweight alloys".

Yes, my wheel question was answered. Many thanks.

And, yes, Graham, it's a '13 not a '15. Typo.
