wondering what is the biggest rear tire I can mount on my factory 1968 Dodge Dart rim ???

13"
14"
4.5" wide
5.5" wide
Steel
Rally

We need just a little more info.

The tire manufacturer will dictate the widest tire for a given wheel width.

Now as for will a tire width fit in the wheel well, that's another question
