I have a 8 stud, 7 "arm", 16 inch, 110 psi rated Sendel brand wheel on my 2008 Bighorn. It is part of a 7,500 lb rated axle so the wheel load rating should be 3750 lbs. The Sendel TO2-66867T seems to fit this description, although all of the online images seem to be of a wheel with just 6 studs. 8 studs comes up on all of the descriptions of this wheel. I found it on E-Bay among other online sources. Here is a listing from the Sendel website:
