Bigs and littles (tires) opinons

Not an A Body: I've got a 64 Dodge A100 pickup. It needs new tires. I will be reusing my 15" ProStar wheels. Since this thing is a cruiser/driver. Whats the general view on front to rear tire size?
When I bought this pickup it had 265/70/15 on the rear, and 215/60/15 on the front (about 4" difference in OD)
I was thinking of going to 235/70/15 & 205/70/15, if I were to used bigs&littles. But if I were to go with 4 the same size they might be 225/70/15. These trucks have a straight axle , and could ride better. By using a taller tire in the front may help somewhat.
So whats you opinion on bigs&littles over 4 the same size ,for a driver (with low power)
