Matter of truing the rim or replacing it

[tulip]

What does truing the wheel mean? I have also noticed that my back wheel is slightly crooked so the rear brake has been rubbing on the wheel. My bike is only a few weeks old. Does riding on uneven pavement and going over bumps cause the wheel to get out of alignment?

If you bike is new, the bike shop should do adjustments as part of the purchase---most bike shops do.

Make sure there is no play in the hub also.
