Dropped on 16" wheels?

[BoostedOne]

See a lot of guys with drops running 15" ralleys, others running big wheels like 20s.

Wondering what most of you that do about a 4/6 drop do for tires on a 16" rim. Thats about the drop I am looking to do, and trying to figure out what size tires I need to go with.

I am actually working on a dually, but most of the dually guys seem to leave the big 235/75's on there, which look like marsh mellows stuffed in the wheel well or they go 19.5s. I was thinking like 235-50's or 60's but concerned they might be too small on the OD and get lost in the wheel well.

Thanks!
