Riding on a flat. How long before rim is damaged. ?

The other day i was riding on some really rough road.. Not sure how long i rode on a flat or maybe - a squishy tire.. I think no more than a couple hundred feet... .. The road was so rough ( pock marked.) who'd know the difference in the ride.. The ride was stable at least. It was the back tire..... The tires are 35 mm in width..
. Now I can't seem to not have flats.. Taking off the tires, I can see no visual damage to the rim.. Might some shard of metal be producing flats.? I've changed the tire for a brand new one..

Where are the holes in the tube? Sometimes a piece of glass or wire can be stuck in the tire and if it is not found and remowed wil give you flat after flat after flat.

Also spokes can give you flats but then you should be able to see the holes are on the inner side of the tube. A damaged or low grade rim tape can allow spokes to penetrate the tube.

Bad.. I've changed both the many tubes I've used for new ones... Along with a brand new tire. The flats still seem to be a problem.

You haven't answered the key question- "where on the tube is the hole?". Put some air in it and hold it under water. Many flats occur on the rim side instead of the tread side.

Don't do it. I tried to ride on a flat for just enough feet to get out of the pack of cyclists. Bad idea -- I lost control and did a nice faceplant. (Yes, it was the front tire.)
