Not rims, hubs and bearings. That may help if there is excessive runout, but not sure if that's where I'd start. First off, do you have the tires balanced? That helps a lot because they run down the road smoother. Not having the tires balanced can also accelerate wear on the bearings.
I would weigh the trailer as accurately as you can, get weights on both sides. Also check your equalizer links, if they are rusty or seized they won't allow both tires on one side to share the weight and one may be overloaded.
Next would be an alignment. You can take it to a shop or check it yourself with a tape measure if you are so inclined, there's a How2 write up on the forum from JBarca. Mis-aligned axles that cause the tires to scrub will heat them up and invite a blowout.
Also check the temp alarm settings on the TPMS, tires that are subjected to any/all of these conditions usually blow from overheating, and the TPMS should be alerting you of a hot tire.
You can also have a spotter run next to you on the highway and look for excessive wobbling, bouncing, etc., or mount a GoPro and grab some video of what's happening when you're underway.
