you are kidding right?
there are no electrics with or on/in the wheels/tyres, the tyre pressure monitor works by sencing a difference between the programed pressure and a change in ride hight/rolling circumfrance..ie it changes when your tyre is flat, because the rolling circumfrence is different
only hummers have the tyre pressure valve system ASFSIK.

thanks for correcting me, i was refering to my car 2005, i did not realise there was a change in the system, but i think the answer would be the same, changing tyres or using foam will not affect the TPS
good luck

Hi mike,
I have a 530d M sport with run flats.
My question is about the spare well in the boot, I bought an 18" rim complete with tyre and I tried it in the well, it did not fit due to a bulge in the well, also I had to remove the PDC box- which is surrounded by polystyrene. How do I fit this tyre in to the well?
How much is the jack from BMW?
Thanks
Lee

A full size spare should fit into the well as far as the diameter goes (the space saver sould have the same overall diameter or "rolling radius", as a standard wheel and tyre) - the restriction being the little slots for the divider in the liner. As you've taken out the polystyrene and PDC controller, I assume that you've got the liner out as well. As you've discovered, the full size spare intrudes into the boot a fair bit - the space saver is certainly a "chocolate button" tyre.
The fixing for the liner means that you have to pop out the BMW roundel in the centre of the full size wheel.
I understand that the wheel/jack kit is around ?150 GBP, but I'm unsure if you can get the jack separately.

That's not correct for TPMS, Dave. The sensors are indeed in the wheels. The FTM system, with the monitor located in the hub, is what you are describing, which was on e60s until early 2006, at least in the US.

For the first time, I'm in the position of needing to change all four tyres at the same time. I currently have Goodyear Eagle NCT 5 run-flats. I have no problems with these other than the fact it will cost me around ?800 to change all four 
My questions for UK owners (presuming we have different views on ride quality?):
If I buy normal tyres, will I find the ride too soft as I currently have a SE spec car. I have not noticed a firm ride so far, so I'm wondering if normal tyres will be too soft? Having driven a Sport spec car I can understand why some owners think run-flats are too firm.
If I but normal tyres, do I need to buy a BMW spare/jack (not cheap I believe) or are these cans of repair foam/glue legal i.e. you don't need to carry a spare?
Thanks.
Ian.

You may have already gone for the non run flats but I thought of doing the same and was advised by the main dealer that if i had any suspension issues whilst under warranty that bmw would not cover as the car has been set up with run flats!!! excuse the french but bollocks, they insist that this is bmw's standing on it!!!

Err, no it's not. Lots of cars don't have run flats or a spare wheel.
sorry mate its law in germany, where BMW get there type approval.
if a car manufactured new after 2005 does not have a spare wheel, then it must have run flats fitted.
a lot of japanese car manufactures use space saver wheels to suffice.
rover cars here in the UK got round this by type approving there cars in india and as such only needed a can of foam to be carried.

Made the change. Same model tyre just not in run flat form. Possibly a marginal change in ride, but hard to tell.
Anyway, saved a chunk of cash
