See any issues with an 820-15?

Currently have a 30x9.5 A/T that came on the 65 Belvedere II I just bought. Any idea if the height and width combined of the below Coker tire will be a fitment issue? I'm using a 15x7 steelie with 4" back space. I plan to have the back end as high as she'll sit and still look good.

Wheel Diameter 15 in.
Sidewall Style Blackwall

Section Width 10.70 in.

Did some more reading online and don't think these fit the bill. Wrong look for mid 60's.
