Hello cognoscenti,

I've searched the forums (and Google) extensively, but I still need some help, and would appreciate any anyone here could provide.

I have an 02 XJR, currently wearing its stock 18x8 "Asteroid" wheels, with 245/40 ZR 18 tires (stock was 255/40, I believe). My father has an 03 Super V8, with stock 17x7.5 "Solar" wheels and 235/50 ZR 17 tires, I believe.

The new wheels I'd like to put on one of these two cars are 18x8 (front) and 18x9 (rear) Jaguar OEM "Aris" wheels from an 05 XK8.

1) First of all, could someone please confirm for me that wheels from an 05 XK8 will even bolt onto these X308s? Per Peter Bock on the XK8 forum:

>the 1997-2003 XJ8/XJR has the same wheel fitment spec as the 1997-2006 XK8/XKR, namely:
>Bolt pattern: 5x120.65 mm
>Offset: MID
>Hub bore: 73.9 mm
>Lug bolt: 1/2" right

2) Also, will the 18x9 rears fit in our rear wheel wells, with the right size tires? Jaguar's OEM "Milan" wheels were available for X308s in 18x8.5 fronts and 18x9 rears.

3) Will these wheels fit over our brake calipers? We have stock brakes, not the Brembos, but we're both supercharged (unlike the XK8) and I want to be sure that the offset for these wheels (20) and the spoke design will fit. (I also have and Audi S6, and only certain Audi OEM wheels will fit over its brakes.)

4) If these wheels do fit, what tire size ranges would work, and which of these would be "best"? The wheels were originally shipped by Jaguar with 245/45ZR18 front and 255/45ZR18 rear, which would be my choice. But, the ratio of wheel widths (8" f / 9" r) seems to indicate a bigger staggering, eg 245 front and 275 rear.

5) Finally, could anyone recommend tire models? The OEM tires for the XJR and Super V8 were Pirelli P Zeros and P6000s, respectively, and for comparable staggered XK8s were P Zeros and Continental ContiSport Contacts.

Thanks to you all for all your previous posts, and any help you can provide here,
