Just a quick FYI.
After a bit of research, I ordered a

what good is an air compressor going to do if you blow out a run flat tire? Im not being a smart a@@, I just have never owned run flat tires so this is all new to me.

From what I have read, though, they can have simple punctures in the tread just like any other tire. If such a puncture is repaired quickly, you don't have to replace the whole tire. On the other hand, if the run-flat tire as allowed to go completely flat, and then you drive on it, you end up destroying the side-wall, and the tire must be replaced. The run-flat tire's sidewall "sacrifices" itself, so you can drive for 50 miles without any air pressure.

I also bought an air compressor for the car. If you have a slow leak, you can re-inflate on the spot rather than running on the flat. I think you can only get about 50 miles on these while flat before the side walls degenerate. I agree that the compressor won't do you a bit of good with a real blowout. I haven't had a blowout in 15 years, but I've had 3 or 4 slow leaks in that time period. |

I guess we need some advise from previous run flat owners that have had flats with them.

Go ahead and shoot me now , but I have had runflats since '07 on my E90, and I love them. They have come in quite handy over the past 5 years. There are arguments both ways on the RFT subject and many threads created about it, so I'm not going to argue that one way or another and let this thread get hijacked by people who despise RFTs.
As someone already said, yes you can drive up to 50 miles (varies depending on the manufacturer), but if you take advantage of that, there is hardly anything left of the sidewall on the tire. The sidewalls on RFTs are full of steel wires, thats how they can support the load of the car without squishing like normal tires. However, if its a slow leak, it is no different than normal tires, as long as you keep putting air in it until you can get to a tire shop for them to plug or patch the tire, no harm is done to the tire.

Had them for a few years and they're really good and brings some peace of mind, ride quality is enhance in F30. All I can say is when there's a puncture you get a warning and depending on how big it you can keep putting air in and driving for a few days while you shop around (like I do).
Of course if the tire is destroyed like hitting a pothole then it doesn't matter it's gone. You get to drive around without the extra weight of pump and tools which is good too. You can get air for free at any gas station. Worse case you call BMW assist and they send a flatbead tow truck (done that twice too)

I have runflats. 3 weeks ago had a nail in the tread of the front right tyre.
Tyre pressure had dropped to 26 psi. After 50 strokes of the foot pump pressure was 24 psi! Got home and 'phoned around but could not find anyone that would do a repair job in SE London/N Kent. Tread depth fronts were 4mm. Did'nt want to drive around with a new tyre at 7mm on one side only. So that meant two new fronts. Checked the rear thread depths and they were down to 3mm. So I decided on 4 new same again runflat tyres, which is quite an expensive bis on an M-Sport. Well it is in the UK! All due to a nail in one tyre! But I must say the road holding and directional control has quite noticably improved! |
