Who's running the same size tires front and rear

67 Barracuda. 215/70-14 on 14x5.5 rally wheels.

Considering that this size won't fit in the spare well (I have a 185/70-14 in there), and that I have an SG rear axle that can't handle mismatched sizes, it's critical that I have the ability to swap tires front and rear in an emergency. I'm not one of those people that calls for a tow every time there's a problem. I like to be self-reliant, and I often drive in areas with no cell service.
