I picked up a chunk of glass... I was running tubes and didn't notice anything until well after the ride. Seems like a good reason to use the tires as tubeless, but is this hole too big? 25mm giant gavia tubeless tire.

Is the tire done? Can I seal it with superglue or something? I could put a tube in it, or is that hole too ugly?

The next difficulty is getting the tire seated with that hole in the tire. With the tube, I needed a lot of soapy water and letting the tire sit at 125psi before it could gradually slide its way into position. It's not fully seated right now, so it's lumpy, and I can only get it up to 60psi with my floor pump.
