how big of a tire can be installed on stock suspension of a 2003 sierra 1500?
This is a question for a tire shop, I would think at least a 30x9.5 Light truck tire.
i have 285/70r 17 on my 01 chev they rub the back part of the fender a little bit when turning but seem to fit fine.
285/75/16 fits with no rubbing at all if torsion bars are cranked and gets aligned
