will 285/70 R 16 bridgestone tires fit on a stock gmc sierra regular cab 4x4 without rubbing or modification?

Answer 1

What year Sierra? 2500 3500? On a 2000 K1500 the torsion bars had to be cranked up a little. No big deal, but should have an align done afterwards. The 00's and up sit a little low in the front anyhow, so it made it look even better when it was more level.
