Suspension and tire help

Decided I’m going to keep my truck instead of trading it in. I’ve been looking at suspension kits and wheel/tire combinations for a while and I want to be 100% positive what I’ve been looking at will be good to go before I buy anything. For suspension I’ve been looking at icon stage 3 and would upgrade to later stages in the future. For the wheels I love the look at the black rhino armory, the issue I have is the ones I’ve found online all have a negative offset and I’d like to have the positive offset wheels, Chances are I just suck at reading tire specs and the stock photo is incorrect. I’m going with ko2 and from what I read in the tire section a second gen tundra with a 3 inch life will fit LT305 /70 R18. The tire thread said that a body chop would be required to fit those tires so I’d have to find a shop that could do that along with the suspension instal. If anyone could help me verify this I’d really appreciate it!

 

For a 3 inch I would go 285/70/18 or 295/70/18's. I run 285/70's on an 18x9 0 offset.
