QP7, you are correct, the less of a difference in tire size you make, the less likely you are to have an issue.

 

OK, so as I am not AWD it comes down to two things 1) will 295 fit on my stock OE 10 inch X351 rear wheels... and 2) will 295 offer much less fuel economy vs other option of 285.. The tire I can out n in 295 is quite a bit more fuel efficient, but the slightly larger width may offset a little.
This indicates 295 is fine on a 10 inch wide rim: - https://tiresize.com/tires/Michelin/...-295-35R19.htm
But some say it causes tramlining?

Also does anyone have experience and / or feedback in the driving differences between P Zero vs P Zero Rosso vs P Zero PZ4.
All good choices to have... I was tempted by Continental DWS 06 but soft sidewalls are not a good match for where I a based... The new Extreme Contact 02 are very good but less availability / choices in tire sizes I could go for the legendary Michelin Pilot Sport 4S, but you give up a lot in ride comfort. The Pirelli UHP AS P zero AS 3 are great, but want to make the Jag this time feel more like a Sports car again so hence leaning more towards the Max performance Summer choices of the variety of Sports oriented P Zeros..... :-) Shame the new and very highly rated P Zero PZ5 does not come in 19"...

EDIT

295 on 10 inch wheels -

The majority seem to say 295 will work fine on 10" wide rear rims..?
