Anyone Have Alloy Wheels On Their Class B+ or C Rig?

My wheels were stamped with 2450#. I bought them used, from an F-series, so it's possible they did change something at some point for the E-series. I should add that I'm routinely over 11,000# on my rear axle, and therefore was very much overweight on those wheels. Often on rough terrain. I've trashed many sets of steel inners as well. I'm now running 2012 Chevy 3500 HD steel inners, which are 17", but I had to get them machined to fir the larger E-series hub.
