I own a 2018 buick regal tourx essence that is outfitted with continental pro contact tx p235/50r18 tires. on 11/6/2019, i found that the front right (passenger) side tire had literally blown out after sitting overnight the garage. it looked like tire had exploded. mileage was 7357 at the time. i am 85 years old and i am thankful that this did not occur while driving at a high speed. car was picked up and repaired by the original dealer.
