I have been debating going to Moab this year, and if I do go I would like to bring some 912's and have some help doing a ball joint flip and lift if someone wanted to help. I have already done about 5 turns on the torsion bolts to level out the VX and already have 285/60-18's on the factory wheels, but my question is,

-After lifting would you prefer going to 285/65-18 or 325/60-18?

Here are the specs from Nitto's website on the Terra Grapplers I am debating on:

285/65-18 Inflated Dia.= 32.52 Width= 11.22
325/60-18 Inflated Dia.= 32.99 Width= 12.83

The tires I currently have on the VX are listed as:
285/60-18 Inflated Dia.= 31.50 Width= 11.50

So what do you guys think? Any suggestions or recomendations or thoughts? Thanks.
