spare tire for f06?
So I've a '15 6er GC with the "run-flat" all-season tires.
After losing 2 tires this past month due to potholes and having to get towed to the nearest dealer. I've decided I want to carry a spare tire with me. I don't want a full sized tire with rim, I want one of those space saving donut tires. I see there are kits for lots of models but I don't see any for f06. Any one know of any kits or any other solution? |

Also the newer BMW computers will go bananas if one of the tire is smaller than the rest, especially since you have xDrive. You would need a full size... |

I asked the BMW roadside tow truck guy what's their policy during the night. He told me they'd tow the car to the dealership for service next day then they'd drive me to the nearest hotel. If you had a spare tire, you'd be back on the road within 10 minutes instead of calling your wife explaining why you'll be sleeping in a hotel that night instead of coming home. Even during the day, the first flat tire took 5 hours of my time, from waiting for the tow truck to pulling out of the dealership with a new tire. The second time took 3.5 hours. Thankfully I didn't have any urgent plans during those days but what if you're getting late for a flight or a meeting? All in all, IMO run-flats are an inferior alternative to an actual spare. |

Not entirely true - if you get a slow leak (from a nail for example) but keep adding air so the sidewall doesn't collapse, the tire can be repaired. Only if you are forced to drive on a tire that is truly flat will you "crack" the sidewall so the tire cannot be reused.
I speak from recent experience with a roofing nail. I did NOT remove the nail when I noticed the tire was soft but put about 45 lbs pressure in the tire before driving to the dealer, adding air every 50 kms or so. (It was a 125 km trip.) There was no evidence of sidewall damage because the tire pressure never got below about 20 lbs.

I had it mounted and drove about 15 miles on it to make sure it fit the GC and it was fine. Besides waiting the overnight if you get the flat far from home after service hours and on a Sunday / Holiday, there is always the risk that the dealer doesn't have the tire in the stock. IMHO for those in the northeast who do a lot of long distance driving rolling without a spare is not a very attractive option. |

What it the maximum you can drive on the RFT? I believe it is 50 miles, although I have heard conflicting numbers that imply it is higher. So if the closest dealer is > 50 miles away a flat bed is going to be needed.

HOWEVER, when my dealer couldn't get me an appointment for a few days and I said in that amount of time I'll put at least 150 miles on it they said " shouldn't be a problem. Keep it under 50 mph" Well I easily did 180 miles and the only time under 50 was on the way up or down to 65. No problem! Still love the idea, just hate the product!! |

RFTs are terrible (heavy, expensive, and noisy). On the plus side, they do work as designed, allowing you to drive without air for 50-100 miles. Plus, the side walls are stiffer than conventionally tires. |

Before I dumped my RFT Discount Tire wouldn't fix my Run Flat that had a screw in the tread and wasn't even leaking air. Neither would Goodyear when I went to them. AND don't even ever ask a BMW dealer to repair a RFT!!: bellyroll |

Isn't that the same mileage with the spare?

The reason most places will not fix run-flats is liability. The reality is, if you pick up a nail, screw, etc. (not on the shoulder) in a RFT, but it continues to hold air (just like a non-RFT), then it can be repaired like a non-RFT. That means a plug for regular tires and an inside patch for high performance tires. In this case, the RFT has not had to support the vehicle with its reinforced sidewall – so it remains intact.
The concern is, if a RFT loses significant pressure, and is rode on for any length of time with the sidewall as a support, the sidewall gets "used up" and becomes unreliable for another (low pressure) use, not to mention potentially distorted. This doesn't happen with regular tires, because if they don't have enough air to drive, you ain't going anywhere. And if you do, then a non-RFT sidewall gets completely crushed and unusable as well. As far as usable mileage, my guess is 50 miles is a significant understatement again due to liability. We unfortunately live in a very litigious society, at least here in the USA. |

Also, just had my 3rd flat tire! And this time it happened at night. Thankfully I was close enough to home that I could call for a ride. I tried driving a little on it but the car became borderline uncontrollable even at only 40 mph. I love this car. but wow. Run flat tires are terrible and its irresponsible for bmw to make us rely on them. |

Good idea.
Please keep us posted on the difference and how they hold up. So tempted but my Road Hazard Ins. won't cover them. |
