  My Jetta had 205/60R-13 on it when I got it.  I swapped those 
for the 155/80R-13 on my Rabbit.  A little higher pressure rating, 
than the skinny ones, didn't handle better, didn't make noticeable 
difference in mileage.  Last 165/80R-13 we put on Dad's pickup 
had a 44 psi rating.  An older same tire, was 36 psi.  ONE order 
older is all.
