Suggestions for alternatives to BFG T/As

My 68 Cuda with stock suspension is running Rallye wheels with 215 70R14 (front) and 255 60R15 (rear). Aesthetically, I like the rake.

Apparently, I'm finding that these tires have probably been sitting for a while during the previous owner's build. Not a lot of grip (also noticed by my mechanic) so I may be looking at new rubber soon.

What are some options to BFG's have others tried on an A body? I've ran across the Nitto 555 Extreme's but I'm looking more for an all season tire.

Thanks in advance to any suggestions.
