Are truck/trailer rims a weak link?

After reading a lot of information in regard to weights and towing on this forum I was crawling around my F350 srw looking at weight ratings for the various components on my truck. I have 3750 per tire, and 3640 per rim (both aftermarket). My heaviest scale ticket shows 6120 on my drive axle, which is under the 7280 weight rating of my rims: when you think about the pounding that happens driving down the road, how often does the weight exceed the rating of the rims?

I have broken several rear rims and 1 front rim over my lifetime, but I have chalked them up to when I de-bead tires, or rock strikes doing stupid stuff driving to places probably above the trucks paygrade.

Now wondering if highway travel and heavy trailers could be part of the problem. How frequently do rims fail?

RV folks don't travel much vs those that make a living on the road so they see/have little experience with wheel issues.
This question is a fairly common issue on haulers forums I frequent. Some haulers may put 80k-100k miles a year on their trucks and trailers so they see more and are subjected to more issues with wheels (steel or aluminum).
When I hauled I ran only steel wheels on my trucks and trailers. I've had busted out centers/cracked valleys and split bead seats from over wheel pressure ratings.

JMO but most rv folks carry weight inside their trucks GVWR numbers....other rv folks seem to understand how to safely carry weight determined by their trucks rawr numbers. So overloading a wheel isn't a big issue on rv websites.
