05 Mustang

I just replaced my 20x8.5's with new 20x10's and I'm now getting an aweful squeaking noise from the drivers side rear area....I did some digging around and hada few things turn up, but nothing that really helped...

I've checked the back of the rim & the wheel/tire clearance...nothing??

I am going to put a set of 17" stock wheels & tires on the rear of the car tomorrow in hopes in pin-pointing what is going on...if it squeaks with the stock set, it's the car...if it doesn't, it's the wheels/tires.....I just don't know....just very aggravated at this point.

Any help would very appreciated....hopefully I will have an update as to what the problem is tomorrow for anyone else finding themselves in this position.
