Look carefully at the first image. The barrel split in two along its circumference, all along the bottom half (halfway between the front and back of the barrel).I'm confused... what do you mean by "wheel separated in half" ... did the runflat come off of the rim? ...did the wheel barrel crack in some way?
It is pretty clear that the runflat went flat and was running without inflation, based on the sidewall wear and tread condition.
Just a guess but I assume the low pressure tire monitor came on, was ignored (or the TPMS was faulty), and the tire was driven on in that state for a long period of time. The run flat offered enough rigidity that the condition wasn’t noticed until there was enough frequent day to day bumps and shocks that the barrel cracked which truthfully looks terrifying.It is pretty clear that the runflat went flat and was running without inflation, based on the sidewall wear and tread condition.
Lmao thank budYikes 😬. Firstly, happy to hear your missus was ok and this occurred at low speed.
I also have the turbines on mine. Hope it's not a fundamental flaw in the design...
If not (and let's go with that for now), that sort of damage could only occur by hitting a South African style pothole a.k.a. a donga. This is the sort of pothole where you disappear down a sudden and steep crevasse in the road (typically caused by poor maintenance of the road infrastructure) then, if your lucky, you reappear up the other side with all your wheels, tyres and bodywork in tact.
They grow like weeds in the suburban wilds here, particularly this time of year as it's our rainy season.
It's one of the reasons I absolutely swear by my run flats...at least I have half a chance of survival...
That is most likely the cause: impact. But that is a catastrophic failure. I would guess the desired outcome would have been for it to bend, not break.My guess would be a manufacturing defect to split like that. I'm not an expert though. I would hope Alfa would be more than willing to take care of that sort of thing unless it can be shown to be caused by some type of serious impact.
