does that mean that i can ignore it? or should i switch out the tire? i noticed it upon a coincidental manual inspection of the tires. i never received a warning from my navi. what should i do?

[a.l.e.x.]

get it patched up. dont rely on idrive

[StarrDlux]

remember to only patch the tire if the nail did not hit a belt. otherwise you may compromise the high speed structure of the tire. the bmw is awesome in terms of safety but i guarantee if you blowout at 100-150mph you will die

alex what angel eye color is that your pic is awesome it looks like fire blue flame/orange flame

take it to discount tire. i had the same thing happen to me, but after a couple of days tpms came on. took it to discount tire, they removed the nail and patched the tire, and after 8k miles still good as new.

tripDHL,

How did you convince discount tire to patch your RFT? The ones I've gone to have said they will not repair run flats because of liability.

it's actually pretty white. the picture is just pretty deceiving.

+1 on discount tire. they did mine for free.

Check out bridgestone or firestone shops- I had mine done at a local shop about a week ago.

The TPMS monitors the tire pressure by the speed of each wheel (at least that is how I understood it reading our E60 owners handbook). The nail in your tire will almost certainly cause a very very slow leak...it could be that the pressure in your tire is still relatively close to the proper pressure, but soon enough it will drop and your iDrive will alert you.

If you want to check this, just check the pressure manually...it will probably by 1 to 2 psi lower or more by now.

Have similar problem here. But I had no choice but to drive about 50 miles on my tire with little to no air in it. I am getting a plug kit today to try and fix it, as it is on the tread surface and does not appear to involve a belt, but was just wondering if anyone had repaired a tire after this much "run flat" time and still used it. I am going to get it replaced regardless, but I may have to put a few hundred miles on it until I can get the new tire on. What do you guys think? Anything to worry about, or should I have it towed?

I had a nail right in the center of one of my run flats. I got a can of fix a flat and it stopped the leak. I put air in it and I was able to drive my car for 6 weeks before I got new rims and tires. I don't recommend you driving on the tire without patching it up...but from my experience, fix a flat allowed me to drive on the tire for an extended amount of time.

not repairable after driving on it that long at 0 psi.

you're asking for a tread separation.

Are you guys kidding? I had a nail in one of my tires and replaced it with a new one recently. Cost me a lot of money. When I asked the BMW dealership about whether or not it can be repaired, they said "absolutely not"!! Is there a real risk driving on repaired run flats?

This is true for 3-series prior to MY2007 (afaik). From MY2007 onward, the 3-series has a direct TPMS system, which measures the actual air pressure using sensors mounted inside the tire.

Yeah, I just found a screw in my rear tire the other day. Brought it to Mavis Discount Tire and they would not repair it. I'm going to BMW today to see what they can do. I really rather not shell out $300+ for a new runflat...

Like other have said, make sure the wheel wasnt driven on at 0psi

Get it PATCHED as quickly as possible to ensure you dont run flat

and BMW actually patched my tire i had to sign for liability reasons and it only cost 5o bucks. I suggest you ask BMW first, the only reason i say that is because they arent going to patch your wheel if it shouldnt be done.

then if the dealership says no, take it to a discount tire and ask their opinion...ya never know, the dealership could be lookin to sell you a tire you didnt need.

I feel safer on my patched tire, knowing that BMW did it...based on that fact alone. they rather sell me a tire, and chances are...if a BMW technician would have come out and said, you CANT drive on this tire, in fact...we wont LET you. I would have taken their word for it.

Dude, truly... there is a risk that a meteor is going to come flying into the atmosphere from space and hit ya right in the noggin'

The people that most recommend that you REPLACE run flats, are the people that sell and BENEFIT to profit from run flats. Like mentioned previously, if the tire wasnt compromised at 0psi, some suggest that you make sure it never went below 2opsi, and you should be A-OK depending on where the puncture was.

if BMW said DONT DRIVE IT, then they probably werent fu@king around...but thats why i mentioned the second opinion above.

BUT, no joke...you can easily patch a RFT and get a full life outta the thing. in fact, one would think a run flat is easier to patch due to strength of the inside of the tire. not as much flex as a rubber tire.

And yet there's no way to see that PSI status from iDrive, sad. If all 4 tires are losing air slowly (as expected) & at the same rate, TPMS won't say a thing.

What is the PSI differential that will kick off an alarm?

You make a real good point actually, but what are the odds that all four tires are going to have slow leaks then again, ill go back to my meteor comment lol...it COULD happen.

It triggered around 5-7 in my case.

[mid-corner fun]

What are the odds of all 4 tires losing air slowly? Guaranteed 100%!!!

Under normal conditions you can expect to lose 1 PSI per month, on non-RFTs at least.

but thats not a slow leak... eventually the air is going to give a bit, and if lost that much air that it would come close to compromising your psi...youre being a putz by not routinely checking your air pressure, LoL.

...so its SHOULD be an unlikely scenario, but thanks for the correction
