2022 BMW 3 flying tires from the factory P zero R19 225/40 93Y RunFlat - front and 235/40 19 93Y RunFlat - rear. The pressure was set as recommended by the on-board computer 2.8 and 2.9. I accidentally noticed that the cord had burst and a hernia appeared at the beginning on the left front, 3 days had passed and it also burst on the right. Powerful quality, provided that I drove 13 thousand km of which 7 winter. Clearly a coincidence and marriage. Can anyone tell me if there is a guarantee for this miracle tire?
