talking head

Just purchased a new runner and I just dropped a fair amount on internal issues and now ready to upgrade my ride. Was recommended some Grabber AT2 285/75/16 and loved the look so I went ahead with that but now I've gotten pretty worried and feel like I should've down more research before listening to my buddy... BUT I know it will be more money but I'm already going down this path and just want to make it work.

I understand I will need to probably cut some fender or make some clearance for it so I also purchased some 1.5" All Pro-Spacers to give clearance. Also still running my 15" stock wheels so that's my main question, what wheels would be the best for my situation? Was looking at some very basic soft unique's or cragars but I'm curious before buying if everything will work out... For example, will I need 16x7 or 16x8? Will the offset play a huge factor?

Really looking forward to hearing back from you guys, can't wait to get my runner going
