I planned to add a tint band anyway, the visor was about 50/50 looks and light blocking. I do know that most of the Lund visors have a gap between the visor and body to allow air to pass.
The window visors on the other hand, those are more about the function. I've got wing windows on this truck, but sometimes I just prefer to roll down the main window. When it's raining this obviously allows water in. With the wing windows, I wouldn't be getting the full length visors, I'd be getting the shorter ones, like these.
Weighed the spare tire I have, and am adding that info to my original post.
