what is considered an ideal lift & tire size is going to vary greatly from person to person.
personally, I'd consider an ideal tire size to be one that is acceptable for the type of terrain you intend to drive on. whether that's highway, mud, rocks, sand or whatever the case may be. I'd consider the ideal lift to be one that includes all facets of maintaining driveability & performance...that means addressing brakes, steering, bumpstops, suspension components, travel ratio, and more...including anti-squat & other suspension geometry properties.
Here's what I did to run 33s.
It may change drastically at some point, it may not. It's been a learning process, and the more I learn, the more stuff I find that is not "ideal".
