wheel size for 67 catalina

[catalina67]

I'm trying to put wheels on my 67 Pontiac Catalina and I was wandering how wide I can go in the rear without hiting my fender skirts if I have airbags on my car and want to b able to pancake it at car shows...it would really help out thanks

with fender skirts you will have to measure your clearance to determine how much wider you can go.
