DBP (David)--- Happy to help, and glad to know you're quite wise with a variety of automotive issues and experienced in racing. Sometimes I don't know what level of expertise a new inquirer might have, so I often try to write in very simple terms to communicate effectively-- I meant no offense on my part, and I know you didn't take it in a negative way.
You can count on us meeting someday, and I will make it a personal mission with anxious anticipation. I am in touch with fellow member ROWHARD (Olympia, WA) on a daily basis, so we already have a little PNW grouping. There are quite a few members from the Oregon area as well, and member DON MOORE is one of our most active. If he see's this posting, I'm sure he'll chime in with some sarcastic comment (in true D.M. form).
My VX is 100% Stock "non-lifted" (no TB cranks, with OEM-RS) and I'm running the famous General - Grabber AT2 in P275/65R18 (32" O.D./44 lbs) mounted on the OEM 18x7 Stock Rims. They are absolutely bolt-on perfect due to the OEM rims without any further modifications; although the fitting is extremely tight, and just had to trim a little tiny triangle corner of front inner cladding (very common).
With a little bit more trimming of cladding and a couple of whacks with a BFH, a 100% Stock "non-lifted" VX can still handle a 275/70R18 (33" O.D.) without any lifting and remain at the stock height (no TB cranks, with OEM-RS). It will be extremely tight, but the 275/70R18 (33" O.D.) will still fit without any lifting (only creative trimming & BFH required). I had once considered the BFG - Rugged Trail in P275/70R18 (33" O.D./46 lbs) due to its extreme lightweight, but instead chose the much more aggressive Grabber AT2 for its incredible specifications in every tire catagory while still being lightweight.
Any tire "OVER" the height of 33" O.D., will require some sort of VX "lifting". Perhaps only front TB cranks; depending upon tire/wheel set-up, and then perhaps the addition of taller RS for even taller tires. You'll just have to play with it as you go.
If you decide to go with the OEM 18x7 Stock Rims with LT285/75R18 (35" O.D.); please take copious notes and pictures during the installation, as you will clearly set the new benchmark/standard for the rest who may be considering membership in the exclusive VX 35" O.D. Club (which there are very few current members). I predict success on your part, and would imagine your lead will be emulated many times in the future by other VX members following in your footsteps.
