Rode on a flat tire - how do I check for possible damage? Took quite a fall today while riding, big divot in a gravel path right over the peak of a small hill. After replacing the chain and doing a quick inspection, I resumed the 10 mile trip to the car.  I did not press on the tires.

I noticed for the remainder of the trip that traction was suboptimal, which I thought was due to the fact they put down fresh, but finer than normal gravel. Anyway, towards the end of the trip I had a major traction issue while doing a slow turn which made me scratch my head, and turns out the rear tire pressure was 0. I have no idea how long or short it was like that.

What should I keep in mind to restore that wheel to safe, usable condition?
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.
