I'm unlikely to venture out again this season, so I jacked up the boat and trailer and put it on axle stands. My thinking is that the trailer is likely to be static for the next 4-5 months and it won't do the tyres any favours.
Better than that would be to remove the tires and store them under cover (garage, whatever.) But, yes, getting the weight off them is better than nothing. If you are leaving them outside, and you have some 303 Aerospace, the UV blocker wouldn't hurt.
