Help with my first lift/wheel/tire setup

[Country Suburban 4x4]

Hey guys I've got a 2000 Silverado 1500 that I'm planning on lifting within the next month, and getting tires and wheels sometime in the spring. I'm looking at the 2.5" Rough country level lift with some 18x9 Worx 808 wheels that would have -12mm offset and 4.5" backspacing on some 285/65r18's. Anyone else use this lift on their trucks? If so what are your thoughts? I'm also not an expert at offset and back spacing. (just went by what Rough Country recommends) Any pictures of a similar setup would be appreciated as well. Thanks
