Wheel size V70 III 16-17-18

Hello dear moose drivers, in line with the beginning of the winter tire period I have a completely inappropriate question 😉 I will now have new winter tires (225/55 R16) mounted on the original 16 inch Volvo rim, on which they should stay. For optical reasons I would like to mount new rims in 17 or 18 inch for the summer tires in spring. My tyre dealer advised me against the 18 inch tires, because they wear off probably faster and I or the moose very many kilometers fr How are your experiences with 17 or 18 inch tyres than 225/50 R 17 or 225/45 R 18 ? Is a higher wear noticeable ? How much harder will the V70 be due to the low cross-sections ? Of course this is very subjective, but a feedback would still not be uninteresting.
