The drums and axles are no longer made so replacement is not an option. Talked to a guy that has balanced many drums by welding on weights. He said about 10% crack when welding so that is not an option since they're not replaceable. Finally went to a machine shop and had them turn the outside. Removed about .100 at the worst spot (still 1/2" thick) at a cost of $50. Fixed now and the drum only weighs 64 lbs instead of 65 lbs! FYI: One post asked about what kind of tire problem - always separation at about 1/2 amount of tread (this will be the 4th tire on this axle). Axles are parallel and square on trailer and I keep it up on stands when not in use. I found a piece of steel 6" x 2" x 1/4" thick (about 16 oz or 1 lb)and strapped it to the drum and it needed a little more to get close to balance. Here's some things I heard about increasing tire longevity (comments welcome) 1) From the guy I bought tire pressure monitors from - "Never run LESS than the PSI noted on the tire to keep the running temperature down - a little more OK" 2) If a 80 psi tire, store at 40 PSI when not in use (on stands). 3) Always keep tires covered when not in use to reduce expansion/contraction of plies (as well as ozone deterioration). Thanks guys for the input - I'm keeping my fingers crossed.
