Many tire manufacturers have limited 14" sizes which sucks.
You can also get chromed Rally II's which look pretty cool on early bird's, I have Cragar SS as well, the old school look is best for these cars, not a fan of restorod crap and 18" tires on muscle cars, looks stupid, also depending on where you live and the roads the 18' and other big dia wheels are crap, you end up with no sidewall tires and they ride like crap and have limited handling capabilities, basically for flat city streets. I've always been happy with BFG TA radials, they handle well and last a long time and have good traction.
