The standard sizes that are in the original owners manual, for both 5 1/2J x 14 steel wheels and 6J x 14 alloy wheels, are actually 185 R14 C or 205/70 R14, both with a 97R load rating. That said the 195 R14 C should also be fine on either type of wheel provided the correct load rating is met. It's just not one of the sizes that VW originally specified.
The big difference that you need to keep in mind between the two is that the 195 R14 has a diameter that is around 5% larger than the 205/70 R14 and so changing from one to the other at the rear will effect your gearing. The 185 R14 size sits between the two in terms of diameter. You can compare the various tyre sizes
