Dart Rear Wheel Question

I'm sure you have all experienced the problems with getting the rear wheel off on '67 and later Darts. I currently have 225/60/14 mounted on stock 14" rally wheels, and they are a little bit of a challenge to get off the axle. I have to get the body of the car up, and hang the axle down.

I'd like to go with a little taller tire, 70 series, but I know that's REALLY gonna be an issue. Maybe if I go a size down on the width, then the wheel will go on and off? I don't know.

I'm wondering if anyone runs 215/70/14 and what issues they may have.

Looking for input. Thanks!
