No - Paint them. High heat paint on the hub and back of the wheel
will keep the rust away from the non-contact areas,and won't let the
rust get going on the contact faces.
And if the tires stick to the inside lips of steel rims, take the
tires off and sandblast & paint the insides of the rims too. This is
a good reason to find a second set of stock rims for your car, so you
can mess with this at your leisure before buying new tires - the paint
really needs to dry for a few days before mounting tires, or Powder
Coat them.
When you change a wheel, then you can either grab a spray can and a
wire brush and put a fresh coat of paint on the mating surfaces to
seal the rust out.
You could put a very thin coat of Anti-Seize or a Synthetic high-temp
grease on the contact areas where the paint rubbed off to keep the
rust out - but that can cause problems.
Luckily I'm in So Cal, and it doesn't get that rusty where they lock
up solid - just the 'keep them painted' trick will do.

Grease the studs and wheel nuts, never. A tiny dab of anti-seize (and
I stress tiny!) is allowed, just enough to get a thin coating on the
threads. Be sure to use a torque wrench and check them periodically.
They really need to come up with a protocol for that - say "with
anti-seize you torque to 90% of dry" but I've never heard of one.
