15” limited choices: Cooper Cobra vs Mastercraft Avenger vs BFG Radial T/A vs ?

1980 Diplomat coupe. I have 225/70/15 because that's the largest I can run on my wheels. 7 inch I think? I have 8 inch steels I'm going to run, but not sure if Uniroyal makes a 245 with a height I can use. I dont want to go much taller than the 225/70s on it. I think 245/65 is as big as I can go
I don’t know about Uniroyals, but If you’re looking at clearance issues there’s a decent selection of 225-255/60/15 tires out there for great prices and a 60 series would increase clearance a bit
