I've bought Mrs Brisel some winter rims & tyres from Fleabay. The winter rims are OEM but don't have tyre pressure monitoring. The factory fit rims for the rest of the year have TPM. Every time the car is started the computer chirps away about it.

Can I turn this off until I put the summer wheels back on? There's nothing in the handbook about it.

Unfortunately no you can't. You will get a bong when you start the car and a warning light on dash. You need the tpms sensors to stop this happening which can be retrofitted normally.

For BMW to supply 4 sensors is £280 and fit all four and balance (weight of sensors throws it out) is £50 - just done the same.

Is is possible to fit non oem valves though at half the price; still need the fit and balancing obviously. Some of the national tyre fitters will do it. Not a DIY job - the valves are fragile and over tightening will tear them in half.

Unfortunately it's a safety issue and therefore insurance and mot failure. No real option other than be glad you've got the tyres at a hefty discount and pay up for the valves. I did the same for my wife's 2014 f30. My 2012 X3 thankfully has the old system that uses the abs sensor rather than fancy valves so those winters bolted straight on. All in I paid less than 1500 for two sets of BMW alloys and sotto/ conti winters - new would be at least 4500 - wouldn't have bought new, too expensive, so pleased in the end.

As for winter tyres they're ace in cold, wet, slush and snow, marginally better if anything on black ice - don't expect miracles but they do work well and the extra grip is noticeable.

Edited to add some insurance cos want to be told you've fitted winters.

Thank you. The BMW dealer said they couldn't disable the TPM either.

Mrs B's insurance won't talk to me so I'll get her to clarify the insurance aspect - on her last car, an Audi, the same insurance company (NFU Mutual) didn't want to know about winters. They logged the fact that she had called it in but as the winter wheels & tyres were Audi approved and reduced the claim risk there was no premium increase.

MOT won't be for another 2 1/2 years yet but I'll check up on the insurance of the non TPM rims. Previously, if fitted, the TPM had to be working which applies here.

i'll be amazed if insurance agree to a tyre strategy ignoring TPM. The reason it exists is because it's very difficult to sense a punctured run-flat. Driving normally on a flat run-flat, at speed and/or distance risks a shaded tyre and the obvious safety risk. I accept that is a similar risk to normal tyres but at least low pressure on normal tyres is detectable.

Sorry that this has truned into a pain for the OP but it's a safety issue I guess.

Insurance co surely unlikey to refuse a claim on basis no TPM valves fitted - how would they know??

they will if they download the onboard fault code store after an accident - BMW can read them from the ignition key...

There's a recent thread on this with quite a few posts.

Summarising, TPMS has been a legal requirement for the last few years and disabling a legally required safety system isn't likely to be acceptable to the insurer.

That's an option but obviously requires the tyre beads to be broken and reseated twice a year. Probably a lot less time and effort to just fit some aftermarket sensors to the winter rims.

The other thread mentioned some reasonably priced ones.

The wheels would need rebalancing afterwards but that would be the cheapest option if they fit.

You might get away without balancing, if you just broke the bead at the valve, pushed it down and changed the valve, but it would be bad practice and there's still the risk of damaging the valves at every change.

At £140 for a set of aftermarket sensors it seems a no brainer to me.

seems to me the OP has a newish car, not cheap. He's bought some BMW alloys and winter tyres of eBay based on what I paid would be about 25% of what BMW would charge and he's thinking of disabling a safety device for the sake of less than £200 fitted. Makes no sense. I bougt two sets of winters off eBay, one for my X3 that didnt need valves changing and one set for the F30 325. I just bought the valves from a BMW MD and paid £50 for them to fit them and balance all four. Pukka parts, pukka job.
