I just picked up a full set of 4 1956 chevy 15x5 steel rims because unless you want to run trailer tires, there just isn't anything in a 14" that is very tall. UNLESS you want to go to a BIAS LOOKING radial tire they make now. Pricy! You can get just about any size you can dream up with a 15inch rim.
Had to look it up, because I didn't remember exactly how to describe it...
The two-digit number that usually follows the tire's section width tells us the aspect ratio, or tire profile measurement. In this example, the 45 indicates that the sidewall distance, from the wheel rim to the outside of the tread, is 45% of the section width.
I'm running 215/70R14 Mastercraft ASIV with 3/4" WSW on 7" repro Wheel Vintique Ralley wheels, so my 62 SS wheel cover still fits. I wish I could find same tire again for my next tire change but Cooper don't make them any more.
