I have a new x1 with run-flat
I have a new x1 with run-flat tires with less than 1500 miles. Today my husband drove over a small screw while parallel parking on a street. I was standing on the curb and witnessed/heard the tire instantly deflate to point where it was very very visibly low. The screw is in the tread. It is Sunday and the nearby BMW dealership was open. We called to let them know we were bringing it in, and to ask the best way to get there via backroads. We explained what happened and he said we should not attempt to drive on the tire with it that visibly low as we risked damaging the rim or wheel well or whatever he said. So we called BMW assist and they sent a tow truck. The guy from the dealership called back and recommended we instead go to a local tire shop, such as a nearby firestone which he confirmed was open to see if they could repair it. He explained that not only was the BMW service center not open, they would not repair only replace.
While waiting for the tow truck we called firestone, who said our run flat tire would likely need to replaced. He said he would look at it, but it probably could not be repaired (again simple tread puncture). Further, he said that even if he thought it could be repaired, he would not work on it without BMW signing a liability waiver. He said they did not have these type of tires in stock so he would have to order it if needed. We could not take the chance of having the tow truck take us there and then being stranded for however long it took to order a tire, so we opted for a tow to BMW. My car sits there now until tomorrow when the service center opens and they can call me.
I am outraged that I have a simple puncture and my new car had to be towed to the dealership. They did give me a loaner car thankfully. This is apparently not supposed to happen to a run flat tire, but it did, and instantly. My question is am I missing something? Could this be a defective tire? Is this something that should be covered by any warranty? I find it outrageous that I had to have my car towed because of a simple puncture. I had no other reasonable options than to have it towed to BMW where I am guaranteed to need to buy a new tire. Even if the RFT had worked as advertised, it apparently would still need to be replaced. That seems absurd. Based on my brief research some places would patch/plug a RFT, but now it seems they want BMW to sign a liability waiver to do so. This was confirmed from what the Firestone guy said.
Any help is appreciated.
