65 Cuda wheels..which way to go?

Huh..I hope that will work. I really like the 215s..

But you're saying the 4.5's were safe for 215s? I only ask because the tire shop guys told me I had to go with wider 14" rims on 215s for safety reasons. I have the 14 x 4.5s ready to go on the 215s..but they said they wouldn't do it.

No such thing as 4.5's.
There are 14x4.5" and 14x5.5" small bolt steel wheels from the factory.
I would not put a 215 on a 4.5" wheel. Your tire guy was correct.

The green Dart has 215/70-14's on 14x5.5" wheels. Works fine on the 5.5" wheels.
