Projects New guy tire size question

Hi.
I'm building a car from cast-offs. I have a good set of doors, a sport coupe shell, nice cowl, frame, drivetrain, and axles from a '30.
I've collected juice-brake parts, and 4 wide five wheels.
A pair of 16x4 for the rear, and a pair of v860 for the front.
I have (4) 6.00-16 bias tires.
Do i want (2) 7.50-16 for the rear,
or, (2) 5.50-16 for the front?

I know the typical setup is 7.50/5.50, but the budget only has room for two tires.
Thanks.

 

I’d do smaller on the front, but you will probably have some guys say they like 5.50 on a hot rod.

 

5.5 front

 

I wasn't sure about putting 7.50's on those 4" rims, so going with smaller fronts is okay by me.
