Thanks sprkplug.
I imagine I could take a little air out of the tire but would have to be careful in how I did that (not sure how much room is left in the tire for air after all the beet juice was installed) and would have to be sure valve stem is at 12 oclock position. But that is something I did not try.

The HDAP are not ag tread or bar tires and the chains do settle down in between the knobby rubber parts. I agree, the tension on the 'circle' is pretty tight, the horizontals not so much, but the tensioner system used in the picture above may help me.

I guess if there is slack, as long as the chains aren't spinning independently of the tire we should be good.

Dwight, the decking on that dock looks great. I clicked the picture to make it bigger and found your pics that are online.

You should start a thread on the awesome modification to the boat trailer that involved adding extra rollers. Never saw that before, that is brilliant! I'd love to know how you make the 'channels' that the rollers bolted to?
