Style 230s are the best wheels for a 335i, and they really do need an LSD
so I think you know what to do

I went a size up (255/35) on the rears when the time came to replace them and they were a bit more cushiony. You can give that a go even with part worns to see if you’d be happy before committing with a refurb. (Fronts would be 225/40)

Avoid reps, they look the same but they don’t have anywhere near the quality of oem wheels. They’ll crack, buckle and be a lot heavier, and a part of you will feel dirty for having reps on such a nice car

PS Quaife LSDs are excellent, they’re so much more sophisticated than a clutch type LSD and you never need to service them. They also have a lifetime guarantee. Some details here of when mine was fitted, followed by a review if you’re interested. http://www.bmwhaus.ie/vbulletin/show...E92-335i/page8
