  Hi  Glen,  Now you've done 
  it. You've got a very sharp can opener. Another can of worms I see here. I was 
  thinking along those lines for the larger 35 foot floating pontoon trailer I 
  was thinking about using to hold up my tow vehicle on the water, and tow the 
  sub with, so I don't have to leave any thing behind, and perhaps leave the 
  water from another location. Once the tow vehicle is lifted up between the 
  pontoons/amas, I would need to drive the whole works into the water, and later 
  also out of the water. This arrangement would also include retractable and 
  steerable front tires.    Since which ever end of the 
  floating trailer that is put into the water first, will start to float soon 
  after entering the water, the remaining end will need to have the powered 
  wheels near that end of the trailer, to come in and out, as well as keep the 
  trailer from scraping the ground.   Some time back I was working thru 
  some ideas for a submarine SUV and needed a way to deal with the compressible 
  and overly buoyant air in your standard pneumatic tires.  Then I came 
  across a new type of free flooding wheel, called the Tweel, by Michelin Tire 
  Company. But as far as I know they are not available as of 
  yet.     http://en.wikipedia.org/wiki/Tweel ese I consider to be 
  a possible option for fully submersible to depth submarine wheels, that could 
  be installed on a sub in many different configurations. Then you can just 
  drive your sub off it's trailer, and into the water. Among other 
  things.   http://www.setcosolidtire.com/   Even better for traction would be 
  to use a rubber track system like you see on small track hoes, and some Bobcat 
  earth mover units.   http://www.bobcat.com/loaders/models   http://www.mississippisuperads.com/Farm_Equipment_Classifieds/C511A482545P1/kubota_diesel_trackhoe.aspx   http://titantracks.com/?gclid=CLC229XKoZsCFUYA4wodxlO-Cg       I had not thought about water 
  filled wheels. Why not rum or the like?   arrg ;}  I'll have to 
  ponder that one for a bit.    As far as oil filled hubs go, the 
  first ones I've seen were on the fifth wheel trailer, that is being used to 
  haul the S101. Here's some pictures of that trailer.   http://cid-5085d10eb6afe47c.skydrive.live.com/self.aspx/Fifth%20Wheel%20Trailer%20for%20the%20S101/DSCN7388.JPG

  Hi Brent  
  Why not electrically or 
  hydraulically driven with optional 
  freewheeling retractable water filled wheels and oil filled hubs 
  fitted directly to sub with some draw bar arrangement....just a 
  thought

  Hey Frank and Brian,  My 
    relative that has build a good number of nice trailers, likes to use Torflex 
    rubber torsion suspension axles from Dexter Axles. They have a nice clean 
    look and they are lighter then your standard leaf spring axles with the same 
    load capacity. This also mean you can get away from rusty leaf springs if 
    you wish. There attachment means is simpler as well.

  Dexter 
    also carries a line of axleless wheel assemblies for those that want to be 
    able to lower a sub between the wheels with out the axles getting in the 
    way, and to be able to transport the sub with it having a lower CG when on 
    the trailer. These axleless wheels are much like the larger ones you see on 
    the semi truck trailers that pick up bins of freshly picked fruit, and then 
    transport them to the packing houses.
  I've toyed with a few ideas for 
    a floating sub trailer that you could let most of the air out of the 
    pontoons to launch the sub, like some ski boats are launched from a float 
    system that is attached to a dock with a air compressor to refill the float 
    system. But I think I would rather have the floating sub trailer with it's 
    small walk around deck to stay on the surface so the launch crew don't have 
    to get wet if the sub is being launched away from a dock or other support 
    boat.
  Here are some pictures of one of Aerocet's models of amphibious 
    floats. The retractable wheels with disc brakes are very nice.  I have 
    been thinking about a larger floating sub trailer with two sets of wheels 
    like this to be able to handle the weight of my tow vehicle, when it's is 
    being floated by the trailer after the sub has been launched. But that's 
    another story all together.  If I was making my own floats then I was 
    thinking of making attachment arms for electric thrusters, that are attached 
    to the retractable wheels assemblies, so that when the wheels where 
    retracted, that the thrusters would come down in there place to save on 
    actuators.
