The scenario as described involved the need to mount a specific set of 33's this weekend.
The wheel wells of the S and the OR, etc., are exactly the same, so it does not matter which he has.
Most 33's are less than 33", and 32.8" would be about average-ish for most 33's, or even larger....so the 285/75/16's are aready 33's for all intents and purposes.
It looks like this is a close enough fit that he can just get the damn tires now, and do the lift later when available, etc....
...Hence the recommendation to get the tires now, and enjoy them.
If they rub a little, so what? Plastic rub is no big deal, and tends to be self clearancing/easily trimmed if desired, etc.
Now, if the question is the width, the 285's vs the 305's = a difference of 20 mm, or sticking out roughly 10 mm per sidewall, depending upon which tire, maybe a range of 10-20 mm total, or around an inch or so more clearance needed than for the 285's (11.5's...)...
....a few twists of the turn stop bolts should address full lock related issues.
Has anyone run into other well related clearance restrictions, like coil or shock clearance, etc?
If so, an SL would not fix that under compression, only at ride height, and a BL would be needed for full articulation, etc.
