Tyre width?????

[miniblob]

Off the back of spotting the 225/50/15's for sale, I'm wondering what width tyres are ok to use on standard BBS alloys??

And also, how wide can you go without any rubbing on a lowered E30???

I know, obviously, very difficult to say without knowing the car, how low, etc, but anyone got any experience with wider rubbers???

Will the 225/50/15's be ok?
I've also seen 235/50/15???

Be nice to know and open up my options a bit more!!!

And the standard BBS are 7J??? So anything above a 205 width wouldn't be safe/advisable on a track car???

Anyone got any experience of using different width tyres on the 15" BBS???
