Count of Monte Crlo

I'm having some difficulty figuring out what some good tires would be that are made in both 215/55/18 and 265/50/20. I'm in Florida so a summer tire year round is fine and an aggressive look is preferred. Of course, the largest concern is always traction and I only want to run street tires, no drag radials (its not that fast...). These are for the 1957 Chevy 3100 pictured below that currently has older BFG KDW's on it, which are not made anymore to my knowledge. Changing to different size tires is not really an option since the 215's are the largest I can go in front and the 265's are pretty close to the fender lips in the rear. I could maybe go slightly larger in the rear, but I would have to measure the space available and the tire specs. Hoping some tire gurus can help me.
Opinions on tires personally used is preferred. Thanks for your help.
