Do you think it's possible that an edge on the cut in the tire caused the second (and maybe even the first) flat? I slapped a patch on the tire, in addition to the tube. I don't know if it will have any effect.
I know, I know, get Marathon Plus. I'm actually planning to order Marathon Supremes. I'm just wondering what happened.
It sounds like you still have something in the tire. Run your fingers around in there...carefully
...and feel for the pokey bit. Alternatively, run a cotton ball around in there and watch for strands to catch on something. This is safer.
You may want to use something to probe the hole of the cut and see if there is still an object buried in there. If the cut spans several cords in the tire, it may be large enough for the tube to sneak out and puncture. Boot the tire or replace it if the hole is that big.
