Jaguar XF handling

I bought a used Jaguar XF (V6 3-litre diesel) a year ago to replace my ageing Saab 9-5 Aero (which I still have and can't part with). The XF has outstanding ride quality but on a recent longish cross country drive, I found the Jag was 'twitching' unpleasantly and needed a lot more concentration to keep it on the straight and narrow.

The car sits on 245x40/19 Dunlop SP Sport tyres.

Is their a better tyre or does the wheel size contribute to the problem? My Saab had a similar problem early on, but using Continental 'ContiSport' tyres cured the problem.

I've never had any handling or roadholding problems with XFs in any of the drive modes. 245/40 R19s are probably the best for the 3.0 V6 275. For the 240 you could go down to 18s.

I criticised the ride on 20-inch wheels. But not the handling.
