70 Chevelle rear wheel size help

[PPS]

I want to confirm the 15x10 with 5.5 rear spacing is the best 15x10 wheel configuration for a 1970 chevelle with a standard width diff?
thanks guys.

I have always ran 15x10 with a 4.5 backspace

All fit on my 68-72 chevelle and 68-69 GTO

30x12.5 15 ET street with rolling the lip

29x9 ET drag with no problem with original Q panels.
