Rode on a flat tire - how do I check for possible damage?
The wheel is unlikely to have suffered any damage, unless you experienced a really hard bump (for example from going over a big stone at full speed). Just to be safe, check the rim for damage (such as dents) and make sure the wheel is still true.
The tire itself is most likely to have suffered. By running on a flat tire, the tire is subject to much more flexing than when inflated - in the long run, this will damage the tire. If the tire has deep creases or is torn, especially on the flanks, you will have to replace it. Otherwise it is probably ok to use.
Finally, make sure the inner tube did not suffer a puncture, and replace it if it did.


With these precautions, you should be ok.
