I know another tire question, I plan on buying wheels and tires for my 1999 Silverado Z71 Ext. cab. I will be staying with the factory 16 inch wheel size will a 285/75/R16 tire fit without rubbing with the stock ride height and no torsion bar adjustment?

 

That's what I have on my 2001 Z71 ext cab with no suspension mods. I think the '99 is the same.
