Anyone else had cracked alloys ?.tried a weld repair but waste of time / money now going for a new wheel?

Yes! Bought my E89 with gloss black 296 alloys and run-flats last November. It was before I had discovered this forum, so I hadn't heard of the 296 alloy problem, so it wasn't something I checked - in hindsight wish I had! 6 months after I bought it, it went in for a brake fluid change, and the "complimentary health check" indicated a cracked rear alloy. Further investigation has shown that it had previously been welded a couple of times in the past.

I have now replaced the 296's with a set of 18" alloys on non-rft's (Uniroyal RS3's). Loving the difference in the ride & handling

Sold the rft's through Gumtree, and currently trying to sell the 296's on here.

Unfortunately it’s a common problem for all 19” BMWs when using runflat tyres - ebay and the like is littered with cracked wheels from all models, especially 313 and MV4s used on E9x 3 series.

There are a couple of theses for sale on EBay at £150 each.

Must have been a very good weld job as I've tried and no one can guarantee a weld repair some say it'll only get an m o t pass and that's exactly what mine did then cracked again

I would take it somewhere else to get it done, I thought I would get it done, thinking in the back of my mind, I would end up getting new alloys, so far so good

If it’s done properly I can’t see any reason why a weld shouldn’t hold. Mine only cracked again after I hit a pothole on the A1. I was fully expecting the TPM to show a loss of pressure after the impact, but it was fine. I had a quick look and couldn’t see anything obvious, it was only when the car was jacked up that I could actually see the new crack. Secretly I was quite pleased when it went - gave me a good excuse to get a new set of alloys past the missus

Yes one of our 19" 326's was found to be cracked and had to be replaced by the dealer before we picked it up.

By all accounts, you're right.

However, the next crack, if there is one, won't be the weld itself, but near or around it.

No. Just remembering other people's posts.

And the knowledge of a friend who's a eutectic welder.

I've made numerous enquiries and no one wants to take on a wheel where a weld has been done previously and cracked again.
Seemingly it's a common problem and very common that no one will want to take it on .

Have you got a picture of the weld ? Is it over or cut through the split ?
Completely pointless simply welding over but all too common

A well done weld then decent non runflat tyres with sensible pressures there is little reason why the welded wheel will split again before any of the others ( jmo of course )
