Not as much difference there.
Let's compare using one tire manufacturer; Michelin Energy MXV4 Plus:
Tire size Diameter
So using the above stats (pulled from the tirerack.com web site) the
difference between 195/60 and 195/65 is 3.3%.
The difference between your 185/65 and 195/60's is half that (1.7%).
The larger the difference is the more likely you are to get into trouble
with the ABS computer.
