Fenton Gyro slot mag wheels for 68 fastback project

I just got these today, haven't cleaned them up yet.
Rears are 15" x 11"
Fronts are 15" x 6"
Both pair are 4 1/2" bolt pattern
Also got 4 N.O.S. Fenton caps
I wanted to get some opinions on what tires you guys would run with these wheels?
I don't have a preference yet radial or bias plys.
The car has the 73 up spindles and cordoba disc brakes.
Also has had the rear springs moved into the rails and inner wells widened.
Bodywork has not been started so fender trimming or stretching is not a problem
Truck Dana has not been cut yet. No gear selected yet.
The car has a 440 mechanical secondary six pack engine with solid .528 cam and a passion 18 spline 833.
I am building this car for street only. Air cond, console and full interior. Weight not a concern.
If this was the 70's I would just buy me a set of formula 1 super stock tires, all opinions welcome, what rubber would you put on them. I can't seem to make a choice on this car.
I will add a picture or two.
