Yep, you are right. I bought the tire off of Matt. They don't swim!

I think that is key. Take for example jpswift1 and Don's Hustler Bigfoots. They are both the same 6x6's with Vampire ASX's but they have two different lower tubs since they are different years with some changes made to the tubs. jpswift1's moves along nicely in the water but Don's is much slower. It just creeps along in the water. There are more factors at play than just the tires.
My guess is it depends on how far the tub is from the body. If its close it probably brushes water off the top of the tire and keeps it from spinning around with the tires. If the tub is further then I would assume the tires are spinning the water around the tires instead of propelling the aatv. Or pushing the water on top of the tires forward in front of you instead of moving the aatv forward. I read years ago before 6x6world about adding flaps on top of the tires to increase speed. Sort of like a mud flap but close or even dragging the top of the tire. I believe a manufacture actually did it factory? I think it was an odd ball manufacture like a penguin or something? I could be wrong though. But I do remember someones talking about adding the flaps. Be an easy cheap test. Cheaper then 6 or 8 tires anyways.
Yep I got them, but I can't part with them as they work too good! I have 9 rawhides but I used them in winter with the tracks.
The Penguin uses a scraper/flap at the bottom rear of the body to help keep water from churning in the wheel well. It is only 2 wheel drive and the wheel wells are fairly close to the tires. https://www.youtube.com/watch?v=5Me1Hk_Rj1M
