As others have said, if it was a tube that followed the radius of the opening, would be a good looking product. Would like to see the gaps filled between the tube and the mounting so that you don't get mud through that gap.
I would imagine that getting 0 offset wheels, and these flare deletes, the angle you would have to be tipped sideways to hit a fender instead of the tire would be pretty extreme. If you have rock sliders that project past the body, I don't really see contact with these being common.
The plastic flares stick out to the tire edge so easy to hit them.
I'm all for the flare delete as both my fenders are creased from the OEM plastic flares rubbing against rocks or trees and were quickly deleted (not quick enough I guess).
I'm just not sure about the design on these. I'll have to see them installed to get a better idea. Ideally a flare delete should just fill the fender channel and not stick out past the fender at all.
