Firstly, I wouldn't be keen on mixing run-flats on one axle with conventional tyres on the other. I'm not saying it would be dangerous but the construction of the tyres are different and therefore I'd have thought it's quite possible you could compromise the handling by mixing the two. I wouldn't say it's as extreme as (say) having winter tyres on one axle and summer tyres on the other but in principle it's similar and something I just wouldn't do.
My mate had a 135i. It was 2014 era I think. You know the 6 cylinder turbo. It was a 3 door hatchback with go flat tyres. As the weather got bad he experienced a serious loss of grip. I know now this was because he had the Pilot Super Sports and they are really rubbish in colder temps. Anyway I have been a winter tyres fan for years. My constant ear bashing persuaded him to try a set. He found someone selling a used BMW wheel and tyre package for his exact car so decided to buy this. Used obviously. The wheels were all matching as were the tyres. So same size front and back. These were genuine BMW run flats. He put them on his car and wasn't very impressed. The car still had poor grip. I started on at him about how rubbish run flats were. He didn't seem convinced. So I offered to lend him a pair of go flat winters in the correct size for him to try. He had these fitted and unsurprisingly they were a lot lot better and he was suitably impressed. This fit and testing was all in the matter of 2 or 3 hours - can't remember exactly. The point is later that day he happened to be travelling on the motorway in traffic at around 55mph. He said the car became unstable. The best way I can explain it is that video clip from Top Gear where they are testing different machinery at the airport. There is a clip where a tow vehicle is driving down the runway pulling several trolleys with suitcases on. This all starts to see saw. And it gets worse and worse. As he explained it to me this is what happened to his car if travelling at around 50 or 55 - I can't remember. He fixed it by driving slower. And obviously swapped the run flat winters to go flats immediately. So it's not very scientific but I know it happened. Car was fine with 4 run flats and 4 go flats. But with a mix it started to exhibit some form of harmonic disruption. Not sure how else to describe it.Hi everyone, I'm new to the forum and thinking to buy my first BMW. I've seen and reserved a 2019 M340i that has everything I was looking for in terms of spec: dravit gray, black merino, comfort, shadowline and technology packs, but also has lots of miles on the clock (~75k). I'm very tempted but the mileage seems quite high. Found an almost identical vehicle at £4k more, same year and spec, swap merino for vernasca and less than half the mileage, both are BMW approved. It'd be great to know what you guys think about this.

20-25k miles a year suggests it's probably seen a relatively motorway focused life. I would have no issues buying in the higher mileage ranges as long as servicing etc was all above board. The B58 is pretty bulletproof and you should get at least a year of BMW warranty. How had the interior withstood the miles?
Thanks for your reply 
I haven't seen the car in person yet, but haven't noticed any obvious marks/creases from the photos and video in the listing, apart from one of the back seats which shows some sign of usage. Interior seems to be in a good condition as far as I can tell. Re: past services, the description mentions 'a service record in line with the high standards set by BMW' which I'm interpreting as a full BMW service history. MOT history shows it passed 2 different MOT tests in 1 month, which seems odd to me, but I'm not sure if it should be considered a red flag.

Had you said M440i I wouldn't have commented. The 440i (previous generation) didn't have xDrive. steve_n said:

My F31 335d came on Bridgestone run-flats and I didn't really like them; the wear wasn't bad (over 20k miles for the set) but for me the big drawback was the level of road noise - admittedly that was a weak point on the F31 anyway but it was definitely worse with the Bridgestones IMO. I swapped to non run-flat Goodyear AS 2's - which improved things significantly - and I think there might be a run-flat version of those for anyone wanting the additional piece of mind of not being stranded by a puncture.
However, come replacement time I'll be going the conventional tyre route again and ditching the run-flats; mine came with Pirellis - which are actually quite decent - but I still think there are better non run-flats out there that probably cost less as well. Still got a few thousand miles to go before they'll need changing but when the time comes I'll be having a look at the Tyre Reviews website to see what they're recommending for 19" wheels. I might even be tempted to a set of CrossClimate 2's as I think they're now available in the correct sizes to fit the M340i...
I plan on non run flat eagle f1’s or pilot sport 4’s when the time comes to change. Will stick a can of tyre weld in the boot beside the air compressor already there. Plus have breakdown cover if all else fails.

There seems to be a lot of new BMWs in stock lately, including a number of these. Some deals can’t be far off
,I made an enquiry on a new car in stock at BMW Park Lane. They called to get details of my current car (2020, 340i, 21K miles). Then never called again which is extraordinary as they still have car in stock.
ETA I just checked and the car I enquired about is still showing in stock. Extraordinary.

I've just ordered for fitment Saturday a pair of Continental Sport Contact 7 for the rears which are needing replaced.
They'll replace ps4s which I've had on for past 16k ish miles. Fronts still OK so will keep them as is and put the Continental when needing replaced.
Went back and forth on whether to stick with ps4s but this swayed my decision with the C7 out performing all other premium tyres https://youtu.be/t10y-87oiD4 and as it happens saved circa £100 per tyre!
Keep us updated, be interested to hear how the Conti's are, I've no longer got my BMW, but my XFS needs new tyres and the Conti's are on my list as well. And as I've gone back to RWD only, I no longer have any xDrive tyre decision issues.They'll replace ps4s which I've had on for past 16k ish miles.
