205/55R16 tire(s) (Travelers Rest)

I am looking for at least one if not 4 tires size 205/55R16. I recently bought a used car and noticed rear end driving weird and front tire on one side having multiple issues with parts needing replaced that shouldn't be wore out and discovered that one tire was different size than all the rest. My teenage daughter drives this car from time to time and I have spent all my money on the other parts that have had to be replaced.
