C-5 wheel swap

[50th AEfan]

I'm looking at a bare set of wheels leftover from a 06 - they are chromed 5 spoke that could become a spare driver set for my 50th. Are there any mounting issues or speedo calibration issues to worry about. I'm told they are OEM and will look for GM logos and part numbers upon inspection. Newer tires of course are to follow. Another research exercise.

O6 is a C6 but I think its a fairly common exchange for the C5. 18 and 19's I think whereas, the C5 has 17 and 18's

Thanks. That’s what I learned but stay with standard sizing. Seen neat informative video on U tube
