Interestingly, I don't think you can get the space saver spare anymore in the UK. But I may be wrong.

21 inch is the worse and limited choices(if any) for 20 inch and a staggered 19 inch set-up as well.

My vote would go to Michelin tyres, I don't think you can go wrong with either of the ones mentioned

Yes, I've tried to look at all season, but the options are very very small, so I decided against it in the end.

If running go flats without the spare, recommend carrying the following with you:
1. Tire plug kit, like this one: https://www.amazon.com/gp/product/B002I52RG0
2. 12v Tire Inflator, like this one: https://www.amazon.com/AstroAI-Porta.../dp/B07QR4Q42L
3. And then some tire sealant as an option of last resort, like this one: https://www.amazon.com/Slime-10012-T.../dp/B000ET8CZC

Ideally you could use the plug kit and the inflator to get you home and to a tire shop to properly patch the tire. If its bad, you'd use the sealant, but lots of tire shops won't patch if sealant has been used. And of course, if you have a major tire failure, these won't help out.

Good point on tyre plug. When I moved to non run flats on a previous car, I went for the dynoplug.

Was expensive...but good for "just in case"!

The big tyre manufacturers need to be given a kick up the rear about the pitiful availability of sizes in 19 inch and above for of All Season tyres in the UK.

Totally agree! My winters are 19" (245/50/19). No all season options at all!

The Conti TS860 is available and I have heard that some people run this as an all season option.

My came as well with them from factory and after almost 25k they are still at 3-4mm and are great but I fancy some Pirelli P Zero if time will come for change.
Pirelli have better rim protection and looks better on rim.

Incorrect, you can install the space saving spare in the well under the trunk floor. Took me about 30 minutes to do it from this thread - https://x3.xbimmers.com/forums/showthread.php?t=1620456

I've found my Continental XtremeContacts DW06 all-seasons provide better handling and more comfortable ride than the Bridgestone runflats.

Those are not available in the UK unfortunately. I looked at what you did - excellent job, but I'm just not handy enough

Did a bit of tyre hunting again today, dam the tyre fitment options in the UK are frustrating for the M40i.
I have a set of 19 inch staggered winter 664 wheels from my recently sold 540i and was thinking that they might be an option to replace the 21 inch wheels since no All seasons are available for the 21 inch rims.
The 19's need 245/50R19 and 275/45R19 to mirror the 21 inch fitment.
I could not find a set of All Seasons, even summers were difficult. In many cases the same make/model that's available for the rear was not available for the fronts. Worse, the one's that did initially look to match, were mixed run flat and non run flats.
I might end up just selling off the winter 664's and find some 20 inch wheels that seem to have a few more options, so maybe a better chance of All Seasons coming in the future.
I really wonder if BMW chose the sizes knowing that tyre choices are very limited and get a commission on the few that are!

The other option is to look for different sizes that closely match OEM and realize that your speedo will be off by a little bit.
