Front tires for 72 Duster?

I have a '72 Duster that I have put new disk brakes and bought new 15"x7" Rallye wheels with 5 on 4-1/2" bolt pattern. I will be driving it on the street with occasional trips down the track. Could someone recommend a good looking tire size for my combination. I already have 255x60R15's BFG's in the rear. So, what looks good with them.

I know you guys will know the right choice.:notworth:
