ReadyLift 1.5/2 lift (conbo of a 1.5" level and 3/2 lift since Timberline is factory leveled) with Falken Wildpeak 295/70R18s on factory rims. I had to remove the front WeatherTech mudflaps and there was a little trimming to the front of the rear fender fabric liners. I haven't heard of this being necessary for others that installed 295s, so I'm guessing Wildpeaks run large.

Front: 37.25"
Rear: 36.5"
Measurements after lift and tires from top of fender to ground:
