Combine that with the boat bouncing while going down the road and you are putting a bunch of down pressure on the axle. I had a Bear trailer under my G3 boat and was replacing tires every 6 months for wearing the same as yours are. A trailer manufacturer explained to me what was going on. I replaced my 1/2 ton axle with a 3/4 ton from Southwest Wheel. Problem solved!! I had the same set of tires for 2 years after that and they were still in great shape when I sold the boat.
I ve got a Bear Trailer with a G3 on it and I put new tires on it last spring and its been to sippi 3 times and to my trailer almost every weekend all summer and that would be around 5000 miles total and I cant even tell that they are worn. I think the key to it is keeping the max air pressure in them and also getting them balanced when you get them put on.

and those tires are past rotating
