Rear Control Arm Question

Hey guys,

Not many people are left on this forum but I'm hoping those that are left can help me out a bit.

I noticed I'll be needing new tires soon. I just took a look at them and noticed it looks like something is scraping on the inside wall on (both) my rear tires. This is the rear control arm, right? If so, is it supposed to be this close to the tire? I can't even fit my finger between the arm and tire so I suspect this may scraping my tire when going over rough roads.

What do you guys think?
