Cindy and I got out to Moab just ahead of the 50th Annual Easter Jeep Safari and got a chance to test out the new Cooper Discoverer STT Pro tires that we recently installed on Rubicat, our Jeep JK Wrangler and out on the Behind the Rocks trail. Here's a short clip that shows just how well they hooked up and just how easy they made it for Rubicat to climb up an obstacle known as Upchuck. We hope you enjoy.
