No lift kit on mine, but I did do the 2.5" leveling spacer on the front. 305/70's fit with no rubbing.
My first set was 305/70R17 Goodyear Wrangler MTR's. Very cool looking. Great off road traction. Downside was its a mud tire, so its noisy... and only D rated. Lasted 25k miles.
2nd set was a 305/70R17 Nitto Terra Grappler. All terrain, so its really quiet. Great looking for an all terrain. I rotated them every oil change and they wore better than any truck tire I've had before. 35k miles... just replaced them with another set of the same tires last week because I was so happy with the first set. These are E rated... so if you tow heavy loads, or think you might tow, you can now have your big tire and your weight rating too.
