06 Sierra SLT

What size, if any, lift would i need to put 17" moto metals w/ -12mm offset on my 285/70-17 bfg AT's? The tires only have 4,000 mi on them but i'm looking to upgrade from stock rims.Torrsion bars are cranked all the way, just wondering if the tires will rub without a lift. Any help would be appreciated
