I am with TommyD . With my 68 Satellite I have 15x8 with 4.5"BS , fit fine with 275/60R15 . Though I now use 255/70R15 on the street . With 8" wide 4"BS and 275's with 4 guys in car I had to roll fender lip due to rubbing . I also have 15x8.5 with 3 7/8BS , with MT 28x10.5 pro bracket radials it gets a very slight rub up in the wheel well outside , this is racing .
10" need 5.5"BS , a couple friends have this on their Plymouths with 295/50R15 , but there is sometimes a slight rub mostly inner wheel well .
The Coronet does fit a 30" tyre easier .
