Actually once the air is under pressure, it weighs more as it's taking up the same volume therefore displacing the same amount of water. The tires, though minimally, are flexible. The higher the air pressure, the more water they displace and are more buoyant. Right? Yes, but I expect it's minimal once you get to the 50-60 psi range recommended for tires. More pressure is just more air per unit volume, so though volume might increase very slightly, there's got to be more air in that volume. I'd say don't run underinflated regardless. Mine is on the ramp, but any current could take it. I just go down as little as I need and it's ok except for the steepest ramps. It wouldn't take 20# on the back of the trailer to hold it if I fished solo. |

You have uprights ? I have mine set so there is positive pressure on the rub rails when the boat is on the trailer where I like it. When the bow is clipped in and snug the uprights keep the boat centered , till it settles in when trailer is pulled out of the water. I added two bunks just on either side of the keel again helping line up when driving on. a Y bracket would do the same without adding floatation to your trailer. I removed mine and added bunks , but if you go to page two of the following post for a visual. seaproforum.proboards.com/thread/5023/upgrading-dual-axle-trailer |
