Offset confusion

So I have about a 2.5 inch lift on my truck and I want to run 33 inch tires but dont want to do any trimming so will having an off set allow that and what size off set do I need. I will not run spacers so I want to know if any one can help me thanks!

 

When you say 33" does that mean 285/75-16 or 33/12.5/16?

I found that Tundra steels like the attached worked great when I had the 285/75 on them (265s in 2nd picture), they are 16x7 +15mm, nothing rubbed. Stock 2nd gen Tacoma wheels are 16x7 +30mm, tucked in more by 15mm, so 285s might rub on the frame rail.

the FJ Baja 'bead-lock' 16X7.5 +10 works best with a 285

 

Rim size?

P-metric or high flotation sizing?
