You could probably go even faster if you get into a good tuck and coast instead.
1. What’s the chances this’ll blow out?
I like everything in FBinNY's response.
If the tire doesn't show any signs of cut fabric, you may try cleaning the cut tread well, smearing some Shoe Goo in there (tire inflated to full pressure), wiping off the excess, and allowing it to dry for a day before riding again. I've done this a couple times when I wasn't ready to give up on a tire yet, and it seems to do a good job of making the tread whole and keeping other crap from getting in there. I'd keep that tire on the back and not venture far away from civilization without a spare tire.
2. What is a good replacement tire?
Bad stuff happens, so the cut may not be the fault of this particular tire brand or model. Tire recommendations are hard with so many good ones out there and so little information on your riding situation...
