Another thought and some clarifications...
While I'm all for keeping and repairing the rims, work is keeping me busy at 60 to 80 hours/week, not including commuting time. If I land this next job, that should keep me rolling at that pace through Christmas. Meanwhile, fall is here, snow is coming - maybe?. At the rate I'm going, I'll probably be paying someone to mount/un-mount the tires and pump the calcium. If so, that will give me a short window to do the rim repairs. If I go that route and get new/slightly used rims, I could save the old and repair them in my spare time then sell them (or keep them as I have a hard time getting rid of something I "might" need later).
As for the calcium... I'm going to price out what that is running on the pump out/refill, as I did hear of a set of axle weights not far from one of my jobs.
How do axle weights compare with loaded tires? I'm not familiar with them. Do they slide around on the axles? Fall off easy on hills/bumps?
Also, I like the idea of the truck bed liner on the rims - great idea. Will probably do that either way.
