BMW run flat tires
Anyone ever had any issues with the run flats? Do you prefer them or have you changed yours out? Thinking of switching mine out

Oh the runflat discussion is well documented. They are shit tires that ride hard and fail easily. BMW is phasing them out if that is an indicator. I went through 9 of them in two years on my F10. The sidewall is all steel so they don't compress and can "run flat". Problem is they don't absorb hits and the impact is transferred to the sidewall resulting in an instant bubble, most of the time on the wheel seal which creates a flat.

What a big difference it makes in a smoother, more absorbent, and a quieter ride quality it provides over the standard 19” Runflats the 540i came with. Driven it on many local highways and back roads and no vibrations. I HIGHLY recommend this for those with a 2022/2023 Sport line 540i if you’re looking for that extra touch of refinement. Do it! You will love the difference. Rides soooooooo much better and honestly feels like it has more steering feel.

The runflats on my G31 have been fine since buying it with them already fitted just over a year ago, with 5mm tread all round, now @ 2mm less than 3,500 miles later.
I would have been fitting Michelin PS4S Zero Pressure but now that it’ll just be me driving it & no need to worry about Mrs Chappers having to deal with a flat. I am currently looking at Michelin PS5 or Goodyear F1 ASY6, both in go flats & either set of tyres is around £200 less than the Zero Pressures. Choices, choices

Some of the decision is for safety, too. I had a 440 with almost 50k miles. No issues at all. It was a convertible, so essentially, no trunk, no spare. I liked the idea I could limp home.

There are two types of thread to stir the pot around these forums. Tire threads and oil threads.
The least reliable tires I had on a car were go flats and the Run Flats on my G30 lasted countless potholes and were replaced due to wear at 40K miles. But not all run flats are identical just like not all go flats are identical. BMW isn't phasing them out though because they don't like them. They are phasing them out because of weight. That's a bit of a setback if you ask me though. As they are giving you a "Tire Mobility Kit" AKA Slime instead. So now you have to pull over on a highway with little or no shoulder with traffic zipping by you at 100MPH and hope that your tire damage isn't so bad that the slime can seal it. A setback IMHO. But tires are as personal as OCI so you'll get 100 different opinions from the 100 of us responding! |

I honestly don’t like the thought of having to replace a 375 dollar tire every time it get a nail. I just had a nail in my suv tire and I’d much rather have that repaired or purchase the 200 tire that comes on that. For the record my 530i came with Goodyear all season sport run flats and I would agree that the ride is bumpy and rough when you do run over something. Also the fact that my neighborhood has 10 speed bumps in and out. Goes over a lot more rough than our other vehicles. SUV and sedan. Just my opinion. Would never try to STIR THE POT asking about tires. LOL!!

Currently, I have a W&T Plan that's pretty smooth. But even if I didn't have one. Costco offers 5Y of free road hazard protection on their tire purchases. BMW offers 1Y. Tire Rack offers 2Y. All free. The Costco coverage is pretty solid as that's the lifespan of your tires under pretty much all conditions except pure garage queen. And 6Y from Date of Manufacture should see them replaced by government guidance anyway. But as ezaircon4jc noted, you can repair a RFT under the same repair limitations of a conventional tire. |

The failure rate of run flats is higher than go flats. The ride is significantly harsher and they don’t weigh that much more. A run flat tires weighs just 2lbs more than standard. So BMW is trying to save 8lbs? Rubbish. Lay off a few Big Macs and you’ve got that back and more. Run flats vs non Run Flat debates is not even close to oil debates as the overwhelming majority of owners hate run flats and when they switch it’s like riding on a magic carpet.

You can absolutely patch run flats. My M5250 came stock with the eagle F1 run flats. I’ve had at least two nails which were in the tread portion and they patched it. No problem.
I’ve also had countless bubbles in my sidewalk. In fact, I just started noticing my steering wheel, vibrating, and found another one. I got mine at America’s tire and paid for the certificate warranties and now basically every time I get a bubble I pay about $60 and I get a brand new tire. I’ve noticed much more bubbles on the front than the rear. I don’t think I’ll ever have to buy new tires again for the front at the rate I’m going by the time my tire gets to a years worth of usage I get a bubble and I get a new one. The rears have held up better I’m about to replace that on my own dime I’m also considering going to non-flats, but I jokingly think that the runflat sidewalk problem turns out to save me from buying tires, because I just keep getting replacements under warranty. You would think after six or seven new tires, which is about where I’m at. They would stop giving me a warranty on them!!

As noted, this is a question on whose answer many of us will agree to disagree. I for one am a big fan of run flats. When they first came out in the early 2000s or so, there were terrible. Prone to failure and they got rock hard after a year or so, so much so that I know even as late as 2007 BMW dealers were sometimes replacing them on a full or partial warranty basis. Today's runflats are much better. I have had all season runflats on all my BMWs at least since 2008 and they have always seemed to have a decent ride and they saved me a couple of times. One time I got a two inch gash that Slime would never have fixed and was able to drive on to a dinner, drive home after and on to the dealer for a new tire the next morning. My 2016 Corvette Z06 also came with high performance summer only Michelin runflats which have been fine. When they wore out I went to all season Michelin run flats, the Pilot Sport A/S3+ZPs, predecessor to the current A/S4s. The ride is good, better than the summer only ones (probably partly because they were newer) and they handle just fine although I don't track the car except for touring laps. I have replaced my wife's 328's tires with Michelin all season run flats and they are fine. When my OEM Goodyears wear out on the 2019 540xi, I will also replace them with Michelin Pilot Sport all season run flats. If I order another BMW, I will specify run flats and if they don't offer them, I will buy my own. Just my $.02.--Bob

I got rid of my run flats. Rougher ride, faster wear, and more prone to flats.
I got a flat on my run flats for no good reason when the tire was in very good shape. I figured I had run flats so let me finish my drive. By the time I got to my destination 30 miles or so later the tire fell apart. It basically got so hot it melted. After that i changed all 4 to non rft. The likelihood of getting a flat on a good tire with plenty of tread is small. It sucks if you get a flat yet but id rather take that risk. Just maintain your tires. |
