Got a flat at 10am on Sunday, 75miles away from home. Called BMW RSA and spoke to 3 different reps. One of them was very inappropriate, like "no spare or run flats!! Really? how?"
Anywho, got the flat-bed to tow me 3 miles to the closest dealer which of course was closed. Filled an early bird form, dropped it with the key in the box, called a cab and paid $180 to go home. A friend drove me this morning to the dealer and they fixed my tire ($50) and back home. From the minute I stopped with a flat till I got in the cab was 3 hours. I was very lucky that the dealer was only 3 miles away (I'm in suburbs and dealer could be easily 60 miles away" and was very lucky to get a friend to drive me back today and save myself another $180 cab ride. That got me thinking fir a plan B. I'm wondering what is the best solution for a flat?
Keep a spare (255/35/19 to fit front or rear temporarily) and tools in trunk?
Keep them at home and get a ride home then back to the car to fix it?
