Yes but they will rub. The biggest tire I was able to run at stock height was a 285/75/16. They are both 33in tires but the 305/70/16's and about an inch wider and will rub when turning.

Im pretty sure they will fit it you crank them all the way up. If not you might have to go with a leveling kit. I had 285/75/16 on my truck and they didnt rub at all until I put a ranch hand replacement bumper on my truck and the front end droped about 2in and then they rubbed.:damnit I had to crank mine all the way up to get it to turn with out rubbing. It was fine after I did that.:woot:

The chevys seem to have more room than the GMC's due to a lower valance the GMC has that really limits going to a bigger tire.

I'd like to go to a 285 BFG A/T's when my stock skins get thin.

on my gmc i just put 265/75 16 bfg mud and there is about half a inch between the tire and the front bumper. It looks close. lvling kitt sounds nice what do they run?

edit: when i turn the wheels there is about half a inch between bumper and tire
double edit: Its stock if that helps any, you prob will need to crak the bars.

Yep, 265's do fit. They came stock on my 3500. I think 285's will rub on a GMC, but might fit on a Chevy.

Will they rub if I crank the torsion bars?

Be careful when "cranking" the torsion bars, You need to make sure there is at minimum 1/2" between the bump-stop on the upper control arm and the frame. I cranked mine and had issues hitting the bump-stops quite often driving around town, made for a harsh ride. Finally broke down and bought cognito's leveling kit (new upper control arms and shock mounts).

Before you consider getting a ready lift or something of that sort get a price for new green keys and extended lower shock mounts, should be about 1/2 the price for the same equipment.

285's should fit, you might have to trim the plastic valance under the bumper a little. I've seen people that run 305's and 315's on the stock 6.5" wheels and I wouldn't reccommend it but it has been done.
