Tire says inflate to 12 to 30 psi. He inflated it to 60 and said to leave it at 60 psi overnight. It wasn't deformed until the next day, but it deformed where the screw penetrated the tire. There's clearly damage to the casing. This bike shop would never attempt to repair a tire. I was hoping to repair it myself to save $100. My main question I guess would be if I didn't leave the tire at 60 psi, would it have still deformed? It wasn't initially deformed at 60 psi. It looked fine until the next day.
Here's a picture:
I'm used to my vintage Panaracer Smoke and Dart tires. The casings on those were a lot tougher. Tubeless is a new thing for me.
