Lug nuts won't stay tight

[fredtoast]

Had soem work done on a tire and a few days later started noticing a noise as I drove. Checked the tires and the lug nuts were looses on the tire that had been worked on. I was a little mad but figured it wa an easy fix. Just tightened down the lug nuts. Now a few days later I start hearing the same noise. Lug nuts loose again.

I think e problem might be that I am not jacking up my car to tighten the nuts, and that it is keeping me from getting them 100% tight.

Any other thoughts.
