BMW X5 X Drive 40D M Sport Best Tyre Size

[Bluepixel]

Hi,
I am considering buying a new X5 40D M Sport and wondered if anyone has any feedback or opinion on the best tyre size, 21” or 22”. I really like the all black 22” alloys, will these give me the best performance, road holding and comfort ?
I should probably add I will also be using this car to tow a caravan occasionally.
Any assistance or opinions welcomed

You can’t have it all. Smaller wheels offer greater comfort and generally less performance. Larger, the opposite.

I don’t think either of those sizes were offered on this chassis, so you’re kind of on your own.
