Dug the boat out, took the fenders off my Kokopelli trailer to make bleeding the brakes easier, and was surprised to see the inside of the front axle's tires worn, severely on the right side, shown. Obviously front axle is overloaded (makes axle bend down in a smile, resulting on increased wear on inside of tires). Reasons seem to be load is forward-heavy on axles or tongue is too low due to low hitch on tow vehicle. Anyway, wanted to post this here as a heads up to check your tires regularly, make sure the trailer is towing level, etc. The trailer tows like a dream, I've had no indication of anything wrong. And with the fenders on you have to make a special effort to inspect the tires which I had not done.
I can move the boat back on the trailer about 5" if I need to, but since my tongue weight is already just about 10%, I'm very inclined to think my tongue is just too low, forcing more weight on the front axle. We'll see.....bummer, I was all excited to get out crabbing!
