2007 dodge caliber

My wife has a 2007 caliber sxt. She drives just shy of 100 miles a day for work and it has 120,000 miles on it. Both rear tires are not standing straight up and down any more. The tops are tipped inward and the bottoms outward. They look like this \ .
What can I do to fix it?
Thanks Richie R

needs a 4 wheel alignment, but first make sure all the control arm bushings, etc., are in good condition.

I had to have every piece of rubber in my 2007 Caliber SXT supension changed. Thank God I had extended warranty.
