XC70 experts

Hello everyone and a good new year! I’m now driving my third V70 (from 2007 2.4D Edition Sport) and have been considering for a few weeks whether I could be happy with an XC70. My approximate driving profile is 30 Tkm/year 50% AB dien other half city and country mixed. In my eye I have a young demonstration car D5 model year 2011 Summum/Xenium etc. in saphirblack with 18 inch Merac. The following is especially interesting to me before I try to get a test ride. 1) On what differences in driving behaviour/driving comfort do I have to agree? 2) Is the Four C especially for the XC70 absolute duty to get the higher center of gravity under control? 3) Which driving differences do the “SUV” tyres in particular cause compared to the V70 ? 4) Does someone with the 18/19 inch wheels (Merac, Erakir) drive possibly quite normal summer tyres, so k e i n e special SUV tyres ??? In the Sufu I’m not quite fündig mich sehr fünd mehr möfrei sehr sehr Vorsuch sehr Besuch ich seine ich seine ersteilen, wieder.
