Original tires would have been either 155SR13 in radials, or something
like 5.20-13 in bias ply. To maintain a similar rolling diameter, a
175/70R13 is very nearly the same as the 155. These will fit the 4.5
inch rims, with a nice increase in contact patch and very little
problem of fouling the body work. (only if your car sits really low).

Unfortunately, I don't have my shop manual here at work ;-) so I can't
help you with this one.
