Trailer wheels and truck wheels have very different wheel offset requirements.
Trailer wheels require a zero offset as the load is carried between the inner and outer bearing. Using a truck wheel with lots of offset can whip a trailers wheel bearing out quick
They also have a different center hole size.

Having the ability to interchange trailer and truck wheels is nice. But the big gotcha is that most truck wheels have enough offset to de-rate your axle capacity. As mentioned, traile wheels are 0" offset for most applications except dual wheel. Dexter axle actual has offset specifications in their available literature online. Typical late model GM 8 on 6.5 2500 HD OEM wheel has 29 mm + offset. I actually had forged OEM GM PYO Aluminum wheels on my Rage'n toyhauler for a while. It road better with 0" offset wheels.
4 complete drums added +- $400 parts plus labor. For me that is more than a couple a nickels.
