15 x 7s, what size would you run on a 68 four door dart ?

I used the 15x7 cop car wheels to check the fitment of 225 60 15s on my 68 dart. I then bought Centerline aluminum wheels with the same offset.
I have green bearings on the 8 3/4 with 4.5" axles and 73 up disk brakes up front. All cleared fine. Front fenders being the closest point. The dana 35 can't be much wider than an 8 3/4 with big bolt pattern axles though or tires will rub on outer wheel lip.
My experience mimics what was previously stated. I do not see the cooper cobras in the 225 60 size on the link?
