I have a 2022 BMW 223i M Sport Active Tourer which came with non-run flat tyres fitted on BMW alloys. We suffered a puncture in a remote part of Scotland on holiday last week & the tyre repair kit was useless. No spare wheel so we needed a recovery vehicle to transport the car for tyre replacement (took 4 days as it was over a weekend).

Don't wish to repeat the experience & no room for a spare/spacesaver wheel. Looking at having four run flat tyres fitted. The car has tyre pressure monitoring. Spoken to several different tyre depots, different BMW dealerships, BMW technical helpline and all give differing advice - from yes go ahead to no it's not advisable.

The M Sport suspension is already firm but run flats may compound the problem. Some mention that run flats can only be fitted if the wheels have a special rim so that in the event of a deflation, the run flat tyre will stay in situ on the wheel. Also some mention that run flats over potholes can crack the alloys.

I just want to know if I can fit run flats to wheels which were supplied without them and that they will safely get us to a garage in the event of a puncture. Would you advise me to go ahead? The alternative is to change to a car with a spare or spacesaver. They are a dying breed and will become even more scarce in electric and hybrid vehicles.
