1998 Dodge Stratus - grinding noise from front tire

I have a 1998 Dodge Stratus, 77,000, 4 cylinder. I recently had the tires replaced on the front end, and when I got it back it eventually started making this grinding noise when I turn right (it also happens when I turn left but not as bad). A light turn at low speeds creates a light grind; a tight turn at high speed creates a grind that makes me wish I wasn't driving it. It seems the more the car leans when I turn the louder the grind. After taking off the wheel to inspect the problem, I noticed the bottom support(pivot point) for the front driver side rotor is digging into the tire rim. I assumed it was the rim and switched over to my full size spare. This helped as it doesn't grind as bad, but it still scares me to think that it could grind right trough the rim. All I need it to be driving down the highway and loose my front wheel @ 80 MPH. I thought it may be the shocks/struts, but I could be wrong. Also my assuption is the rotor is fixed to the rim and the support is fixed to the rotor; so why would the support grind into the rim? I do live in Hawaii and there is a thick layer of brake dust and road grim on the supports, could this be a factor? Any help would be appreciated.
