That's correct. The car is, however, a German import if it matters.

Yes, they are "Borbet" brand aftermarket alloy wheels. I just went to
look at them. They are 15x7, ET35.

So that's where my wheels should go, then :-)

I just got the crazy idea to look in the user manual. It actually does
specify wheel sizes. It states ET45 for all rims except the 7 inch,
which is specified at ET42 (not identical to the North American
recommendations, it seems) This means that my 7x15 rims should have an
offset of 42 mm, which means mine are 7 mm too wide on each side. Is
this enough to cause a noticeable handling problem?

The only tire size listed for 15 inch rims (either 6 or 7 inch width)
is 205 wide. My tires are 195 wide. Could this cause the problem?

What should I do to solve the problem?

In Norway, most roads have deep ruts. These are what cause the
problem: The car wants to pull out of the rut, so I have to hold
steering pressure to keep it into the rut. If the wheel goes over to
the other side of the rut, the car pulls the other way, which is the
same way I am holding steering pressure. The car suddenly moves in
that direction, and I have to sharply steer the other way to keep in
lane.
