So I've got this clicking noise I cant figure out...

A couple weeks ago I had to slam on my brakes going 90 km/hr to try to avoid hitting a deer, but I ended up hitting it at around 30 km/hr on the right side of my bumper. I got a dent in the hood, but everything seemed fine.

The next week, I had my winter tires put on, and ever since that, when I lightly-moderately press my brakes, I hear a clicking/grinding from the right rear. It slows down and gets louder the closer I come to a stop.

Does anyone have an idea of what could cause this, and if the deer or tire changing could have affected it?

Thanks!
