I currently have Centerline wheels all around on my '69 Custom S:

Front: 14x7 or 8 with BFG 245-60-R14
Rear: 15x8 with BFG 275-60-R15
Slicks: Rally II with MT ET Street 255-60-R15

I want bring the car back to a more original look and have managed to find four 15x7 Rally IIs at a local junkyard from a '73 Grand Prix. I've restored previous junkyard Rally IIs which I use for my slicks and they came out nice. In a separate post people shared that a 275 will fit in the rear with 15x7 Rally IIs, so I should be good there.

I'd like to use the 15x7s up front as well to help fill in the wheel well and make the car look a bit lower. I'm wondering what the maximum tire size is that I can fit up front using a 15x7 Rally II? All four rims should have 4.00" backspacing.

I'd like to use new 15" 245s (like I have now on the 14x8s), but I doubt they will fit? Will a 235 or even a 225 15x7 fit without clearance issues? If not, would going down to a 50 series tire be an option and still have a somewhat wider tire? Then I'm wondering how the car will look with 50 series up front and 60 series in the rear? Does anyone have any side view examples of that you can share?

Thanks for any advice!
