Replacement tyres

Hi
I am looking at changing the tyres on my ‘97 XK8 which has the 18x8/9 rims. The tyres are not particularly worn but they are 7-8 years old (the car was stored for 4 years before I brought it).
The current tyres are as per the Jaguar recommendation of 245/50 Pirelli PZero directional front and 255/45 PZero Asymmetric rear
So I was wondering why they had different tread patterns front and rear, as Pirelli don’t make 2 different PZero tread patterns any more (and I don’t think other companies do either)??
I was also wondering why the fronts were 245/50 (dia 702mm), and not 235/50 (dia 692mm)? As the rim diameter of the 235/50 matches the diameter of the rear (687mm) better? Also the recommend ideal with for 8” rims is 225-235, and the max is 245. Was it just that 235/50 was not a common size back in 97, or is that max width or 245 is needed??

245/45R18 in front and 255/45R18's in back would be the best setup for a staggered set of 18-8/18-9 wheels with lots of tire options.
The wheel offset of an XK8 makes even 245's visually look too small. I would not want to go narrower.
On my lowered '97 coupe, I would love a square set of 9" 18's all around with 255/40's.
