I purchased a 2015 BMW X1 M
I purchased a 2015 BMW X1 M back in January of 2015. It is now June 2016 and I'm having to replace all 4 tires. Is this a normal time frame? The current Pirelli P7's on it are apparently only good for 15k miles. I'm a female, there's no spare in the car, the tires are already at 4/32nd's. I'm leaning towards putting run flats back on it regardless of what has been mentioned in these comments here, although all very interesting points. I don't want to be replacing tires again in winter 2017. What gives? What's a better All Season run flat tire?
