That's one of those answers that starts of with "Well, Kinda"
If you read the literature from the Lift kit mfgs the advise is to run a 4" lift for 33's but practical experience tells us that you can run 33's with stock suspension. However, if you do any 4wheeling that involves a lot of axle articulation they're gonna rub & maybe wrinkle some sheetmetal. Same sorta thing with the 4" lift & 35's just not quite as bad. A 4" lift will provide good clearance for 35's and will allow a fair degree of articulation but under some conditions it may still rub. A 6" lift will give you enough clearance for *any* condition and that's what the mfg's push. None of them wants people badmouthing them & saying "yeah, I ran their lift with X-size tires and it wrinkled my quarter so no my truck is f*cked up" so they go the safe route & recommend a lift that will give you clearance regardless of how high you jump the thing. An easy solution is to run the 4" lift, 35"/36" tires and then an extended bumpstop so that you never hit sheetmetal even at maximum compression.
****, I worked on a friends truck that had such badly rotted wheelwells that we trimed a good 6" off it, ran bushwacker cutout flares and he was able to run 38's with bone stock suspension & Rancho extended bumpstops. There are really very few hard & fast rules and if you're willing to make compromises then there's almost no limit to what you can run.
