I have exactly 64.5 miles on this tire, which makes me angry. Today, out of nowhere, thumpthumpthump - the back tire goes flat. It's a Maxxis Detonator 700x25, which is supposed to be pretty durable. So I change out tubes, ride maybe 50yards, thumpthumpthump. Another flat. I inspected the tire, and saw nothing looking like a cause. I did end up finding a puncture in the tire.

Is this tire shot? Can it be used(by putting a patch or something on the inside. From the outside it looks bad, only if I squeeze it (like in the picture). The inside doesn't look all that bad. Is it trash?
