Calling all Runflat drivers.....buckled wheel?
Discussion
Hi folks,
Can you help? My daily drive is a 2010 plate 3-Series touring, fitted with 18" alloys & runflats (Photo below). I wanted to ask whether anyone else on PH has experienced a buckled wheel on runflats (aside from mullering it into a pothole that is). Here's the context....
The car is great. I hate the runflats. I vowed to be rid of them when they reached their natural cycle last year, but a nasty puncture when the rears were on the wear markers put paid to that strategy. I had a new set of rears fitted (just before Xmas) and noticed straightaway I had a mild vibration from the rear as I drove the car up the motorway. The symptoms were exactly the same as an out of balance wheel, so after returning the car to the tyre place (within the hour) they took both tyres off & confirmed I had a very mild buckle on the NSR, which was causing the vibration.
Now, I'm going to leave the name of the tyre company out of this discussion to avoid any finger pointing. All I can say is they are one of the best independent garages in the country and have supplied & fitted race wheels & tyres to a well known racing series for the last 8+ years or so, as well as race tyres to me in the process as well. Nett: I completely trust their technicians, I know the owner well, and defer to their expertise.
I was shown the buckled wheel rotating on the tyre balancing machine. Even to an untrained eye, I could see the buckle. The puzzling question was why I hadn't felt the vibration with the previous set of tyres. So, we fitted the old set on the car again, I took it out, and yes, I could feel the vibration. The chaps at the tyre garage said this was not an uncommon occurrence - particularly on BMW's - with runflat lower profile tyres. So, it's definitely the wheel.
A replacement wheel is in the post from BMW. I'm going to get it fitted this week and will post up a report. I'm just puzzled how on earth I could have hit something so hard as to buckle a wheel? I tend to obsess over details of any car I own. In particular I remember clearly any time I'd have clouted a speed hump / pothole / other in the car and...well, I just haven't. There is a series of those nasty synthetic / Polyurethane humps on a driveway into my kids school. I literally have to slow to about 2mph to go over them without the suspension crashing. Maybe it was one of those taken a little too quickly?
Has anyone experienced the same issue?

I thought the cracking issues were normally on the 19" wheels due to the lower-profile run-flats.
One of mine went (style 230) which manifested itself in a slow puncture. I took it to BMW, they performed a run-out test, and because it was outside of their permitted tolerances I got a new wheel for free under warranty.
There's a large thread on e90post.com which might be good reading for you OP.
