Okay, so let's just use the same rule-of-thumb for the tires.  1600lbs
per tire load rating.  I still cannot find out what the load rating for
the Audi 16" X 7"
4A0601025P alloy wheel is.  Even Audi of America replied with this
response, "Kevin, thank you for contacting Audi of America. We do not
have that information here; this address is designed for general current
vehicle information. Please contact your Audi dealer for the load
capacity; for any additional information you may need on the Vanagon,
Volkswagen of America would be the best source." -AudiTalk

There has to be a manufacturer's code or specification sheet for this
wheel out there somewhere...
