tires for my new 15x4 rims

I picked up a 67 notchback that is getting the following;
front disk brake swap
s/s leaf springs relocated in to the frame
mini tubbed
8 3/4 with a sure grip and 3.91 gears
15x10 rims with 315/60/15 drag radials
15x4 rims with ???
and finally new paint

Should be complete in 2-3 weeks, and I'll post picture than.
