Not unless there was some unusual circumstance- like the lugs were so loose that the entire wheel was loose too.
The important thing to remember is that lug nuts DO
have to be tightened in a particular sequence (pattern) and, naturally, that sequence differs depending on whether your wheels have 4, 5 or 6 lug nuts.
