A plug worked for me. Here is my post from an earlier thread:

http://forums.e60.net/index.php?showtopic=4296&hl=

I had a similar experience. I got a nail puncture in one of my runflats and my dealer told me they could not repair it per BMW policy. After a little prodding the service tech conceded that a plug might take care of the problem, but that he couldn't do it for me because of instructions from some higher authority. He kind of? while he said this - conveying the message that a simple plug would work for me. I'd tell you who the dealer was, but I like the guy because of his honesty and I wouldn't want to get him in trouble.

I went to the local Midas shop and got a $5 (US) plug and there have been no problems for about 4000 miles. The dealer was going to charge me $384 (US) for a new tire.

The official line from BMW and the tyre manufacturers is that you can't.

Indeed. A few hundred quid is worth it to be safe

Run Flats can be repaired just the same as any other tyre. A friend of mine is a manager at Dunlop UK and he assures me that provided the Repair company has the correct equipment for removing run flat from the rim and provided the technician has been on the relevant training course repair is not a problem. Most towns in UK have at least one authorised repairer.

From link: Speed ratings are not valid for repaired , re-treaded, under-inflated or overloaded, excessively worn, damaged or altered tires.

Sounds dodgy to me?

I received a FTM warning at 3500 miles and also thought it was a malfunction. It wouldn't reset so I brought it to the dealership and they found a nail in the middle of the tire, removed it, plugged it, charged me $40 and I haven't had an issue since...currently at 11,000 miles.

Repairs definitely void speed ratings, as you've now compromised the structural integrity of the tire itself. It seems clear that at 140 MPH, that little hole, with its little rubber plug glued in will be much more susceptible to failure than an unrepaired tire.

That said, if you drive at "normal" speeds, and the tire's been repaired properly, it shouldn't cause a problem other than potentially springing a leak.

My run-flat has now been unmounted and patched twice - it developed a slow leak the first time - and it's fine. I just don't treat it like a Y/Z speed rated tire. I'll replace it soon enough, but with only 6,000 miles on it, it seems a tad bit wasteful.

In Germany it doesn't void speed ratings, it's illegal.

I had a flat at a similar milage. I think they are getting nails and screw in the tires before we buy them. Either at the factory, port, or vpc.

Illegal to repair, right? Not illegal to void speed ratings.
