How do you tell if a wheel is worn?
There are still grooves on the braking surface but a straight edge shows that there is a very slight concave (1mm) to teh surface.

Is this a problem?

    some have wear indicators, like a dimple, when it's no longer visible it's time for a new rim

    but unless they were very thick rims to start with, 1mm is deep!

    if your's are worn concave that much i'd say don't ride them, the tyre could blow off or the rim could fracture

    Is your 1 mm measured or estimated? If it's 1 real mm it's time for a re-rim, if at all possible on your wheels, if it's only half a mm, then keep riding
