what rim/tire for spare in 71 rr w/ 15" rallyes

what is the correct rim and tire for a 71 roadrunner with 15" rallyes? thanks in advance!

It would be a plain black 15x7 steel wheel with the same tire as on the rallyes.

black "450" wheel with F60 or G60-15 Polyglas GT

Would the spare wheel color be black or body color for a car that came with body color rims and dog dish hubcaps?

thanks guys, I figured it might be somthing like that, but you just never know. whats a good alternative to the 450 wheel? I dont want to spend that type of money for a spare, but yet be as close to correct. thanks!
