I can tell you for an absolute certainty (because I've just been out to my car and looked, with a torch) that if you look on the drivers side B pillar the data is there, clear as can be.

I assume you've got something like the 403M wheels. If you have a look at the sticker on the B pillar, it gives various sizes, depending on the wheel size. So just look at the sizes given for 19" rims.

Oh, and the sizes you've got on there are the standard tyre size (and yes, bifferent front and back) for that wheel size on an MSport 3 series touring.

Run flats are OEM - i.e. specified by the manufacturer.

If you want to run 'normal' tyres, you MUST inform your insurance company and get their consent.

I personally use run-flats, and HJ recommends that they are used. Changing a wheel on the hard shoulder of a motorway is a very quick way of getting killed.
