lift level 2009 double cab long bed

here is my dilemma I need tires I want to run 33x10.5x17 tires I understand that some trimming will have to take place. Problem is I need tires like yesterday. don't have the funds for a new suspension at the moment.
So to I'm thinking of getting the low range off road kit for the time being then I can get tires I want. I'm unsure of what to run for suspension though. I dd the truck an I use it for my rental properties hauling tools lumber etc. I want to do some more traveling/overlanding so i want it to be capable off road. Do I need a stage 3 icon lift? For what i intend to do I don't know that I need a 5000 suspension. I'm not saying that suspention kits of that caliber are over priced just unsure I will see the benefits of something like that.
I'm open to all suggestions an what's has or hasn't worked for your rigs.

 

did you ever find this tire size anywhere?

 

I went with 255/75/r17. Going to run 255/80/17 on the next set.

 

What does the 9n part mean? Mayb e im losing it lol
