My front passenger wheel seemed to roll back quite a lot

When changing to the spare wheel, the drivers front wheel did not do this. Do I have a problem?

When changing my wheel due to a puncture, I noticed as I was tightening the wheel bolts to secure on the spare wheel that the wheel seemed to move back without much effort. I tried this with my hands, again the same happened. I tried my other wheels and all the wheels on my other car and this did not happen. Has the pot hole I hit the other day caused more damage that I dont know about?
