I was going the same exercise. The 14" tires are only slightly better then the
13". 15 and 16's are better, I think 16's have a bit more selection these
days, but still limited depending on tire (all purpose vs track).
Has anyone
run 205x50x15's on the front and 225x50x15's on the rears with Panasports or
other wheels without flares?
One thing I did was get the sizes that I think
would work and go up to the tire rack and see what brands and styles of tires
are available. You can also see the specs of the tires which give a good
indication of width and circumfrence to allow comparison of the different
tires.
Not sure if the Tirerack has the calculator but a good one that works
is this one, simple standalone and nicely done

Rob, I have the 15 inch panasports,
with 195/50 15 Dunlops on the front and
205/55 15 in the back. I like the
combination, although 14 inch higher
aspect ratio would probably ride a bit
better with slightly less steering
effort.
I think you are correct about
tire availability being better for 15 than 14.
In addition, this combination
on the rear wheels gives about 8 percent
larger rear rolling diameter, and
therefore a slight overdrive effect
compared to the stock 13s, something nice
if you have a four speed.
America's Tire Company has a very handy plus size
calculator on their web
site which will give you the differences in rolling
diameter, speedo error
etc for various fitments. Try:

Good luck.
