widest tire for 6" rim

I have the same or a similar question regarding my 1967 Barracuda Notchback.

I currently have 195 70-14 on 6" front and 225 60-14 on 7" rear.
I was thinking of moving the 225's to the 6" wheels up front and buying a set of 245 for the rear. Will this work?

According to this chart:

It looks possible, but the max width for both wheel sizes. Has anyone successfully done this? I also question how well the 225's will fit in the front.
Any insight would be great.
