Odd rear tire problem

[Rusty_Nail]

So today I was noticing that the tire itself still holds air pressure fine but when I sit on it its flat but tire is firm. So I'm sure the inner tube is fine(was replaced less than two months ago). I did a few months back accidentally hit a small pothole in the road at about 20mph approx. Replaced the inner tube but not tire. Could the tire alone be defective? It's had a lot of punishing miles on it.

I've always used double walled rims. I kept getting flats. I eventually discovered little shards of metal inside of the hollow part of the double walled rim. With some patience I got all the shards cleaned out.

What PSI are you running?

I'm also curious about the pressure... I run 35-40 PSI.
It's possible that the tire itself might be damaged; Sit on it & look for the sidewalls bulging out anywhere.

I've run some scetchy tires before lol. I had one with a whole worn through and the tube was literally coming out on the tread. I somehow rode that tire for a week before I got a new tire and it never blew lol
