Old 15x6 Cragars, Tire Size?

I'm going 215/70.
Found a post on fbbo, guy put 225s on a 7" wheel with 4.25 bs on a 62 Dodge and the tire is close to the leading fender edge.

My wheels are 6" with a 3.75 bs.
The cop wheels fit with 215s, and I'm sure those are 7".

A real rough estimate, measuring from the front of the cop wheel, where the lug nut sits (wheels on another car now) it's 3" to the edge of the wheel.
Same measurement on the Cragars is 2.5".

So, the Cragar won't stick out as far as the cop rim, so the same size tire should clear the fender.
