When I replaced my stock tires last year I glanced in the garage as they were doing the swap. They had the stock tires sitting to the side, and were mounting the 33x11.5s. I was surprised by how much bigger the new tires looked. Yet, they only measure 31-1/4" from the ground to the tire shoulder (a little higher to the bulged out center, but I didn't need that measurement for the Hypertech).
