Plenty of other expert advise in this thread and on this topic.

I'll just say that I run 205/55-16, "standard" offset 7x16 Fuchs, on my '87 front. Mine is lowered to "Euro" spec, has a street alignment, and is otherwise mostly stock.
My fender lips are rolled, 180-deg up, but not to the point they touch the fender inside, so I don't see them trapping water.
Since rolling the fender lips, I have never had tire contact.

I suppose there's a chance fender/tire clearance may differ between cars. Maybe my fenders are pulled out more? No damage history, just hand-made car differences?
Anyway, just offering up a data point.
