I just purchased a new 2021 XC40 R-Design, and mine includes the 20" 5-double spoke wheel option. But having driven the same exact car as a loaner for a week (2021 XC40 R-Design) but on the standard 19" R-Design 5 poke wheel - I felt as though I liked the ride quality slightly better on the 19's (plus I just like the visual look of them). Considering buying a set of the OEM 19" wheels/tires, and wanting to make sure I can simply swap them (they are shown as 'approved' tires on the Volvo website) - or does the car have to go back to dealer service for any sort of calibration?

And if anyone is interested in a set of barely used 20"s in the Boston area, let me know!

 

Have you taken delivery of the car yet? Most dealers will do a "delete option" if you wish to downgrade wheels. If you get OEM spec'd 19s and use the correct tire size, there shouldn't be any calibration. Check out wheel-size.com for the OEM rim/tire specs for the 19s vs 20s.
