Hello everybody ! Very newbie and must learn how to post in the forums etc. New owner of a 2003 Suburban Z71. Have 17 inch wheels and a 16 inch spare. Need to find someone that could answer my question as to the ability to hang a 17 inch spare under this vehicle. I don't want to buy 4 17's and one 16. I appologize for probaby being in the wrong forum, but any assistance would be greatly appreciated.
