2018 Chevrolet Colorado Tires & Wheels Problems

At approximately 6:15am while driving at approx 45MPH on a surface street on the right lane, I noticed an alert on the dashboard regarding the PSI of the rear driver side tire had 0 PSI of pressure and simultaneously heard the thudding sounds of a flat tire. I neither heard, nor felt any impact and there were no potholes in that section of road. I pulled over and called for roadside assistance to replace the tire with my spare. I noticed a large tear from the tread nearly all the way down to the bead along the wall of the tire. Tire M+S 255/65 R17 110T. When the tech arrived he noted the tire was new (purchase and installed 42 days earlier). I asked if he's seen this before as I hadn't, and he said he'd only seen it when a driver hit a curb, which I had not. In the early evening I took the tire back to the shop where it was purchased and before even looking at the tire they informed me I "must have hit something" and will just need to purchase a replacement. After they inspected the tire at my insistence, they concluded I must've hit something but I believe it was a case of confirmation bias. I pointed out, and they did not refute, that there was no other damage to the tire, no damage to the rim, and no damage to the vehicle. The subject tire is still in my possession and available for inspection.
