Ive looked but haven't found any rim weight specs steel or alum. no sense in puting on tires with a 3400-3600# if the wheel can only carry 2500#
You didn't provide a clue as to what vehicle you own or are inquiring about so it's pretty difficult to answer your question.
03' 3500 single wheel, 2wd, quad, 6 speed, 3. 73, blue, power pup, vanakin. junk factory alum wheels and factory steel wheels. no markings as to weight rating on any normally there would be. that should be enough info (this is still the 3g fourm right)
