I decided to measure the ground clearance of my new 2016 Land Cruiser. I made 3 sets of measurements: after I bought it (factory), after I mounted larger tires, and after I had the lift kit installed. The measurements were made with no cargo in the car, on a flat hard surface, and with very little tire wear. These are not high precision measurements, or even highly accurate. I simply used my Stanley tape measure.
The results are not surprising. The larger tires raised everything as expected. The OEM tires are 285/60R18 (31.5" diam) and I mounted 275/70R18 (33.2" diam), so that should raise everything 0.85 inches. For anybody without a favorite, I use the site tiresize.com. The 2 inch lift kit raised a few areas but did nothing for the rear differential (duh).
