2023 Volkswagen Tiguan Tires Problems

Was driving on highway at 74 mph when the vehicles loss of air warning light came on. Five seconds later, I heard a pop which caused me to lose slight control of suv. Managed to pull safely over to the right side of highway where I managed to put on the spare tire. Luckily there was no other car to our right when the tire blew if not we would have hit another car and the incident could have been much worse. The tire was taken to two Volkswagen dealerships and they found no signs of nails or glass. It is unknown what caused the tire to rupture in such a way that it left multiple holes and cracks on the tire. The tire size is 255/45 R19 100H M+S
