I just took of the 215 x 75R x 14" tires and put on 215 x 70R x15" on 15 x 6" wheels on my 57 Ford.  The back wheels and tires were really tough to get on, but once on, there is plenty of clearance.  FYI, the tires I put on are BFG Radial TA Touring Pro's and are T speed rated with a narrow WSW.  This tire is only sold at Sam's Club I believe.  The car rides and drives much better, the steering response is vastly improved too...I have power steering.   I would be interested to hear if there is some little trick to get the rear tires on and off.  I have been considering adding a leaf to my rear springs to firm up handling and raise the rear a little bit.  I don't like reversing the shackles, although I think Karol Millers 56 Fairlane had them reversed.  I am concerned that if the springs were stiffer, it would not let the springs drop down as much, making tire changing even more difficult.  I think the new wheels and small hub caps give the car a high performance look, but probably looks better with 14" wheels and Turbine wheel covers, with or without fender skirts.  Any tips appreciated.

Thanks,
