Runflat keeps going flat!

[minischnauzer]

Ayn ideas? Just before Christmas my front passenger tyre went flat, had it replced with new tyre - 24 hours later flat as a pancake! the garage then closed for the xmas-new year break.
Mini recue put on a spare and took the tyre to BMW who cleaned the alloy put on the tyre again, kept it for a few days to check the pressure. They put the tyre back on my car, happy driving for 10 days then flat!!! I then took the tyre to my usual tyre bloke (great guy should have gone to him in the first place) He refurbed the alloy and put the wheel back on, this time I was sure that the problem was solved. It was for 5 days, then flat again yesterday!!!
Went to see tyrebloke who is completely baffled, he checked both the tyre and the alloy, couldn't find anything wrong. He seaprated the tyre from the wheel to try to isolate the problem and I have to check the presure everyday - Only 2 days so far but no loss in pressure, so hopefully thats the end of it.

Has anyone else had a similar problem?

I had a problem fairly simular to this over christmas.

Basically kwik fit put two new pirelli runflats on the front for me. 10 days later my tyre pressure warning light came on. I got the technical guys at work to check them for me and they couldn't find a puncture or anything so they put the pressure back up for me.
A few days later, same again- though this time one went completely flat. I took it back to kwik fit who couldn't find anything wrong with it and said the only explination really was that someone was probably letting my tyres down at night

4 days after that, it happened again so I just took it to the MINI dealership who discovered that the tyres hadn't been sealed, they were balanced static and clip on weights were used instead of stickys. So basically, Kwik fit in swindon don't know how to fit runflats.

Not exactly the same as yours but thought you may want to check those in case tyres have been put on wrong...

I am beginning to think that someone has been letting them down, so it's in the garage at night now. Thanks for the reply - I hope that's the end of it.

I had this problem when I replaced the rear runflats on my Cooper S. I was back & forth to the tyre fitters 4 times before they announced that one of my alloys was badly corroded in the inside therefore not creating a proper seal.

They suggested I get all my wheels powdercoated as "...this is a problem with Mini alloys..."

I had the same problem over xmas. Had a new pirelli run flat fitted just before xmas holidays and 2 days later the tyre was completely out of air. Had to drive around in my classic mini because all the tyre shops were closed (so much fun)!

I went back to tyre shop who checked the tyre out and said it wasn't sealed correctly-it's been fine since (fingers crossed).

One of my Pirelli's was loosing about 5 lbs of air every 3 days. The tireshop could not find a leak anywhere. So I had them remount the tire. It's been 3 weeks and the tire is fine. I think they paint a sealant around the bead when they mount the tire so that seemed to do the trick.

I've had this problem for nearly 2 years with my 53 plate cooper (had it from new). I've got the 17" S spokes and I've gone through tyres like there's no tomorrow. Every few months one of the tyres will start to lose pressure and, depending on if I'm close enough, I have to find a tyre shop quick smart that is willing to take off a runflat and refit it.
The shop takes it off, cleans the rim, paints on the bead sealant and puts it back on again. It's ok for a few months and then it happens again. Every shop I have been to has said that this is a problem with these wheels and that they've never seen any other wheels from any other manufacturer start to corrode so soon. The car is well out of warranty now, but has anyone had any luck complaining to BMW about this? It's just happened again to me today. I've only got 3 months left on the lease so I don't want to buy another tyre. The clutch is also a bit flaky!!! (65,000 miles).
