[Tjalle]

This was discussed at X4 thread about a year ago - but then even more serious - bad corrossion already after 1 year - my rims are 30 month - no warranty left.

I was lucky that tyre hotel was charging me twice what I thought for storage. "Season" meant only 6 month!. Hence I have my 310:s in my heated garage - also luckily my bad rim was at top of stack - had not discovered it previously.

Creep corrosion comes from cracks in clear coat, where water can enter and corrode aluminium- especially polished aluminium.

As in most cases starts at center of rim. Mine is only 3 by 4 mm, which is why I had not previously noted it.

I showed the rim to dealer, who took pictures and today I got the message that I am welcome to have my rim exchanged.
