Welcome to the forum.

If money is tight, forget about new wheels and work on the wheels you have. Find a tire place you can trust and pay to have all 4 wheels and tires taken off and sanded smooth around the area that the tires seal. It would be a small pain, but if you have a hose anywhere around where you park, try giving each wheel a quick rinse after you've been out in any kind of roads that they might have thrown salt on. Even a bucket with a sponge and clean water will do the trick of getting the salt off the edges of the wheel. The thing is to start with a clean sanded non leaking wheel.
