I have a loadmaster aluminum trailer and I placed aluminum wheels on it and now it started floating , I took 60 lbs of lead and strapped to it and it still floats any suggestions.

Put the galvanized wheels back on it..

Yeah, Put a Mercury 2.5 EFI on the back, and see what the top end you can get out of it.....

Put a motor on it and use it to boat.................you know th old saying ....if it floats...take it from there

did you change to larger/wider tires along with the wheels.....this might help explain the added bouyancy.

Don't be afraid, why do you want to sink your trailer?
My 2 axle aluminium trailer floats.........and, that's with a 4500LB Pantera on top of it! That is the easy way to launch, it's called float on/off

Disconnect your transom straps before launching!

While you're improving your trailer with aluminum wheels, why not also install billet stainless steel bunks? That will solve two problems at once; no more floating and dried up wood...

You could try adding the liquid weights to the tires. This is the same stuff the farmers use in their tires. It's not cheap though.

My South Florida trailer does the same thing. I don't worry about it when launching unless there's a current at the ramp. Then, I just have someone pull it out of the water as soon as the boat is free. When retrieving, I back it in until just before it floats, load the boat partway on, then have someone back it down the rest of the way. Works very well.
