Could someone please explain to me why the 14" vendetta tires swim better then the 16" vendetta tires on some machines.
I would think with the higher bouyancy and wider paddeling tread on the 16's would win. What am I not getting?

hi keith , hope your doing well. looking forward to april mud. not sure on the answer to the tire question. maybe the 14 '' sit lower in the water which gives more tire area for paddling . we ' ll see . later , j.b.
There are several factors that come into play: buoyancy, water resistance, hydrodynamic drag from both the tires and the body, and probably some other factors as well. It's a lot to take in, I just assume that every machine performs differently in the water and in the mud. You can tweak something here and there to maximize performance, but it can be hit or miss such as the 14" and 16" Vendettas.
Several owners of a Max IV seem to say the 14" are faster in the water then the 16" which is why I brought up the question. I always thought that more tire above the waterline due to better bouyancy would be an asset. With the body style and drag the same there has to be something about the larger tire that makes it slightly slower
I have a theory but lets leave that to the engineers, i do belive it has to do with cavitation from the water being thrown in front of the machine and exiting propelled water.
My new beer holder spilled some on the trails - in it's hair and down it's throat.
Joe Camel never does that.
Advice is free, it's the application that costs.
That might bring us back to the thread started by a fellow member (sorry I can't find the post to give credit) about using wipers to help direct the water that gets kicked back up and around the tire to a more useful direction that would help propulsion.

What do the vendetta's run?
My vision is the water needs to move forward to actually (aid in momentum) push the body some ( which is why Argo and Max IV seem to be fastest in water from wheel well design) the excess needs to drop between body and tires and escape, now with 4" more rubber it may be causing flow issues along with throwing disturbed water in front of the machine from the outer sides causing cavitation. Like swimming in a jucuzzi, no races are won when you are grabbing air bubbles.

I've long considered adding some kind of detachable bladder to buoyancy system to the front of a machine to direct water away from the hull and add some freeboard to the front.
This is an extreme example of what I'm speaking about, but if you look at the added floatation to the front of the Amphibious Assault Vehicle, I think you will understand the concept. The key for one of our machines, is to add just enough to redirect water flow, and still keep mudding capacity.
