15x12 rims on 33s?

[snj8198]

33-12.50's stretched on 12's are big in Hawaii for some reason. When i was there and asked the beach dudes they said it was for floatation when running on the sandy beaches. I smiled and nodded but that doesn't make any sense. Airing a tire down for floatation makes sense but the side wall needs to flex and 15x12's wont keep the bead easy with a 12.50 at single pressure digit.

So if useability, practicality and looks aren't there then there's no need for it i guess.
