Hello, I have a MS on the way that has the standard 19in wheels. I really wanted the 21s but didn't want to pay that crazy price for them so I found some used ones. The used turbines are from a 2015 model S and wanted to make the swap educating myself on what needs to be done. Since these are older, does it make a difference if the cars computer rejects them? Does the computer have to be adjusted for the larger size?? Any insight from going to brand new 19s to older 21s would help. Thanks
