Hello dear forum, I have on my BMW 330d from 2013 (F31) the original BMW rims styling M 400. First they were mounted 4 summers, then 4 winters. I admit that I don’t care for special light well or often clean (tuga aluminum devil green). But it can’t be normal that rims, which are marked as “winter suitable” after 4 winters are already so rotten and defective: varnish bursts large area, yellow and black discoloration, bubble formation,… -> Images s Is this “normal” for Aluflegen after 4 winters? Is the quality of the BMW rims bad? Is it the rare cleaning? (“Winter rims” have to cope with brake dust and salt?!?!?) The rims can no longer be saved. But I think about which rims I will drive in winter in the future. Thank you for your brief assessment.
