Hot Rods Guess this Model A Wheel and Tire Combo?

I know this is a Hamb'r xadamx's car don't think he's been on in a good while...Anyone have a good guess on the wheel and tire combo here? Thank you! Best Pics I have sorry!

 

Reverser Wheels ? and looks to be a stock 32 Ish rear end

 

Wheels appear to be 49-51 Mercury based on the hubcaps nibs.

 

Wheels are Chinese, made in the past few years.
Merc wheels don't have safety rims ...

 

I guess I’m more interested in the tire size. I’m thinking they’re 5.60 15 upfront? Maybe L 78 15 in the back?

 

If he was going traditional build I'm going with 5.60 front, 8.20 rear

 

Really hard to tell With those photos but the back tires just don’t look as tall as a 750-16 would. Probably closer to a 650-16 don’t know how they translates to a 15” wheel but it’s something.

fronts look in the 5:25-550/16 range
