cracked alloys
Discussion
I need to replace my alloys on my 335i as they need a refurb due to scuffing and a couple of cracks, they are I believe the more basic ones for that car, although I couldn't tell you what they are apart from being 19" Now I fancy some different ones any way and seen some good deals on ebay and need to keep to 19" as I just spent £400 quid on Michelin pilots on the rears, the ones I was thinking of replacing them with are MV4's but found out from an old thread on here believe it or not that these were prone to cracking too.
Now the question is, are wheels prone to cracking because most people have run flats on them which I assume don't absorb the pot holes etc so much, or would they crack for a pass time any way? I got rid of run flats and the ride is so much better, they don't crash over the bumps and pot holes so much so could this help or would the wheels still crack? I also assume that wheels could crack more because of the lower profile tyres rather than the style of wheel which 19's would have but would like to think that softer walls may help the problem. Thanks

If the MV4s are the stock wheel for the pre LCI 335i , I only had issues when the RFTs were on , causing from full refurb a slight bucking in just 6 months.
No issues at all once the Michelin’s were on for the same amount of time.
RFTs were deemed the sole cause of the problem in the opinion of my tire retailer and alloy wheel refurbisher.

No idea what the stock wheels the MV4's were for, there were just a set of refurbed ones going on ebay for 600 quid and I thought they looked nice, mine is a pre LCI car and hoped that the run flats may have not helped any cracking issues, as the cracks on mine happened with run flats (before I owned the car). I just really liked those wheels, but if they were prone to cracking regardless of tyre, I may need to think twice, but a positive response so far

RFT was the majority of the problem for the cracking wheels, yes, but even with go-flat tyres, sooner or later you’d have no choice but to hit a bump/pothole and crack a rear with the (style 225) MV4’s. IMO they’re simply not up to the job on British roads.
My most helpful hint would be to avoid trying to straddle the little ‘square’ speed bumps & go over them (slowly)with one side only, as that avoids putting all the stress on the inside rear rims, right where the camber exacerbates the issue & so all the load is in a very narrow section. Rears were much worse than fronts for cracking (although fronts do crack too), as the wider rears & their separation distance is near-as-dammit the same as these speed bumps.
As I understand it, the later version of the wheel (no idea how to tell by looking, but made by Chromodora, I know that) is a bit better/stronger.
They’re still one of the best wheel designs for the e9x though, and don’t half look good. I still have a ‘perfect’ set in the shed on the off-chance of ever getting another e92.
If you can find a set, style 269 are much the same design, and meant to be a lot stronger (anecdotal, no proof).

Low profiles are also an issue in a similar way to RFTs but it’s still mainly down to road conditions. IMO,
Sounds like with 19" wheels, therefore lower profile than 18's it may always be an issue then, I generally am careful over those square speed bumps, the ones around my way are quite shallow so I just prefer to go over them square on as the roads I use, there are 2 side by side so I just ride them without bothering to swerve around the road so one goes down the middle of the car. My route is generally the same day in day out so can avoid pot holes as I know where they are. I do very low miles any way, so hope wheels shouldn't be too much of an issue then as I am not on run flats,

The wife ran an e93 335 with mv4s for about 7 years.
Ended up getting 4 alloys replaced in 2 years when running Bridgestone RFTs.
Swapped them for normal tyres, no more knackered alloys for the next 5 years.

I ran a 530d for 4 years, 14-18. Not a puncture or cracked or damaged rim. 18” 45 series tyres.

I would imagine that was as much due to a learnt change in driving style after the previous experiences.Ended up getting 4 alloys replaced in 2 years when running Bridgestone RFTs.
