need help for new tires quick!!

Hey guys im due for a new set of shoes. found a great deal on nitto
terra grapplers. so i did some searching and want to verify what ive found beforei order..

I currently have the 5100 lift in the front of my 07 dblcb longbox 4x4. Its set to the
3rd notch from the bottom. i also have rear aals. right now i have 265/70/16 tires which dont seem to fill the void that great. I also have dick cepek dc-1's with -5 offset i believe. i just want a little taller tire. im looking at 265/75/16. From the research they should fit fine. just want to make sure?? The diameter will go from about 30" to close to 32". I can also raise the front another notch if need be.
Thx for the input greatly appreciated!!

 

Nevermind found a thread 3 posts down about putting 265/75/16 with no lift so i should be fine!
