    theres a guy on here who's driving a 2004, i think, silverado with leveling keys on 35" all terains. he had to do soem bumper trimming though. I have 33's on and i just cranked my stock torsion bars up as far as they go and i ony have rub when i turn hard right, and even then its very little. i just need to grind down a bold about a quarter of an inch. so safe zone is 33's or less, and pushing it is 35's

    The 88-98 Silverado dont need to be cranked to get 33s or 285/75/16 (32.8) on them, they sit almost level from the factory, the 99 and on silverados have the front lower then the rear even on a 4x4.

    it looks like you will need to trim up the front bumper some. you will more than likley get some rubbage when you turn.

    I have 285/75/16 on my suburban and have planty of room at full turn, no trimming, so a 33" will be fine as long as its not super wide
