Bad press on run flats?

Hi,

I have a 2015 428i where run flats came standard. Reading all the bad press, I was dreading the day I'd run over a nail. Well it happened last Friday, and I must say I'm very thankful I had run flats. I ended up driving the car for 4 days (which included at least an hour at 80mph on the freeway). I only realized I had a nail because I noticed a "thwap-thawp" sound coming from one of the tires at low speed.

The local tire store ended up finding out that I had actually 3 nails, and all had punctured all the way through! The repair was free too (America's Tire, not sure how much it costs at other places, I wouldn't think more than $50). Now I know run flats are noisier and hurt ride quality, but honestly after this experience that's definitely a trade-off I'd be willing to take. I'm pretty sure I got the nail around the airport where I flew in around midnight. If it wasn't for run flats, I could've been stranded on the side of the road in the middle of the night after a 12 hour flight in a seedy neighborhood. I'm sure those with families and young kids can appreciate this even more!

Sounds like you were not loosing air from your tires, so having run flats didn't make a difference. If you had lost air, your TPMS would have alerted you. The RFTs come into play after you have lost air. Non-RFTs go flat and you need to stop driving on them. RFTs go flat, but don't look like it because the side walls are stiffer and don't let the tire collapse and you can keep driving on them (with restrictions). Sounds like you would have had the same experience with or without RFT.

Maybe you "could have" been stranded, except for the fact that you don't indicate that you lost pressure in the tire, in which case, the run flats didn't actually do anything for you that a normal tire would have. The run flats provide a benefit when you lose pressure...no need to stop on the side of a freeway, in the dark, etc, etc, and change a tire or wait for roadside assist.

I have been told by many places that they will not repair run-flats.

Huh? You are telling me that America's Tire (e.g. Discount Tire) repaired three punctures on a single run flat tire? That goes against every tire manufacturer, U.S. Tire Manufacturers Association (USTMA), Rubber Manufacturers Association (RMA), and even America's Tire own policy and guidelines.


BFGoodrich: 1 repair
Bridgestone: 1 repair only if 15 psi maintained
Continental: does not recommend
Dunlop: 1 repair
Firestone: 1 repair only if 15 psi maintained
Goodyear: 1 repair
Kumho: 1 repair
Michelin: 1 repair
Pirelli: does not recommend
Yokohama: does not recommend

If you didn't have runflats you would have had something else to compensate would you not (e.g. spare, donut, sealing kit, AAA)?

As someone mentioned, if you did not experience pressure loss, your run flats did not perform any differently than a non-run flat tire.

I ran over a 3" by .25" metal rod on Thursday with my non-run flat summer tires. Didn't figure it out till I tried to go to work on Friday and it was totally flat. Got my slime kit out, slimed the tire, went to work, then got it plugged at Midas. Held air great with sealant. I kept the run flats so I could put them on at any time, but the performance sucks, worst case I was thinking I might have to put them back on while I find new performance tires for treadwear, but nope.

Except that if you drive on the run flat while it's flat, it'll get you somewhere, but you destroy the tire sidewall in the process and it has to be replaced, which if the treadwear is uneven can be a huge cost, especially for AWD.

Yeah, that's what the service tech told me (I asked him twice since I also didn't quite believe it), although I don't believe he was the actual one doing the repair, so he may not have been right. He did show me one of the nails and it definitely looked long enough to puncture all the way through.

Yeah, now thinking about it I realize you guys are right. I hadn't lost pressure (or a significant amount at least) because my low pressure indicators did not go off.

Although I was very happy that the run flats could be repaired so easily. This was not something I was expecting based on what I'd read online.

Just spoke with someone at Americs's Tires and they recently received "permission" from Pirelli to do a one time repair on their run-flats

whatever that means. Pirelli legal in black and white
"PIRELLI TIRE DOES NOT ENDORSE:
1) The use of tire sealants in Pirelli tires to repair, even temporarily, a puncture;
2) The repairing of V, W, Y or Z Speed Rated tires;
3) The repairing of Run Flat tires."

Sounds like goofy stuff going on at America's Tires.

it's not rocket science; however, if the shop repaired three nail holes on a runflat tire, I would not be happy at all. Again, if a manufacturer allows for a runflat repair it limited to one only. I would question what kind of repair that shop actually did or didn't do and if they did it properly or not.

Well, I just violated two of those last week on my P-zeros at Midas...

Does not "endorse"? What does that mean? It certainly isn't an outright prohibition. So it's in black and white, but it's clear as mud.

Let's hope they're right (and I believe they are) or else you're driving on a tire which likely suffered damage resulting from continued operation for four days and up to 80 MPH with a loss of air pressure.

IMO if the tread depth of the remaining tires is sufficiently low enough to be of concern I would replace all four tires anyway. While they technically may not be at the end of their service life they're sufficiently worn where I would consider replacing them anyway.

So the nails may or may not all have actually punctured the tire but either way the tire did not leak. Did they charge you just to pull a few short nails out of the tread.

Are you sure they are run flats.

There's further statements to refer to RMA and USTMA guidelines, as well as the tire shops referring to all three. It's a point the finger to whoever does the repair for liability. But I will say, that every tire shop I've gone to for national chains in my area have been extremely rigid on what they will or won't repair based on RMA, USTMA, and manufacturer recommendation. So, I'm pretty surprised that there are shops, local, regional, or national chain, which would assume the liability. Especially with run-flats, which should always, always, be removed and inspected at the very least if there was any air loss due to puncture.
