I went from 14" rims to 15" about 1.5 years ago.  On the 14"
I had run Michelin Agilis and Hankooks--both 185R14.  Plus
another tire on the van when I bought it.  It is a Westy Syncro.
I never liked to go about about 60-65 in it.  It just didn't
feel good to me.

On the 15" rims I put Nokian Hakka Cs--205/65-15s.  This is the
single best change/upgrade I have made!  I was on I-10 in
west Texas last week--80 mph speed limit and a headwind.  I
was cruising at 80*, passing the semis, and it was rock solid.

I went with 205/65-15s because the diameter is exactly the
same at the 185R14s.  I didn't want to change my gearing or
speeds per rpm or the low range characteristics.

The tire is directional and I bought six.  It has been very
good to me on rough roads and sandy ones.  It seemed to gum
up some on the one very muddy road I drove but I got out.  In
general, on back/rough roads it is far superior to the narrow
185R14s.  It is about 1" wider, plus the agressive tread.  As
I recall, they cost $132 mounted and balanced here in Boulder.
