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.
for the universe of 205/55 x16 tires that I have in my dB the metric for the shoulder clearance ranges from .771 to .952, bigger means a blockier tire shoulder w/ less clearance at the lip
Pirelli P7 Cinturato is .771
Dunlop Direzza ZIII is .952

all 4 BS Potenza variants are clustered @ .833 to .845

there is some variance from car to car but I haven't run into an irreconcilable difference for that tire size on that wheel
