I have a 97 3500 4wd dually and was wondering what's the biggest tire that will fit on stock height? My dad had an 02 a while back that he ran a set of 255/85-16s on and had no problem. But every retail tire place suggests the biggest I can run is a 225/85. Anyone know?

 

I think the 255 is it .. unless you go spacer ... 1" you can run 285/75/16's then .,..
