Full-year tires on XC90 II during summer vacation Spain

Hello together, someone has gained experience of how all-year long tyres like the Goodyear Vector 4 Seasons behave as 275/45 R20 for a stay in Spain? Some people tell me that you can throw the tyres away afterwards. Is that true? Or is that just fearmaking? I have had problems with the same tyres on my polo for 3 years and neither in the very hot summer nor in the winter with snow in Germany. Ok, it weighs a lot less than the thickness. I would be grateful about lively experiences or assessments. Oh yes, I am a very leisurely driver. Neither extreme acceleration, nor hard braking maneuvers.
