A few weeks back, we got the chance to drive the all-new Polaris RZR XP 4 Turbo in the sand haven of Glamis. Knowing that not every UTV enthusiast can even get to Glamis, we decided to take it on another test voyage to see how it fares in harder grounds. With just 120 miles on the odometer, we bolted a set of new STI Chicane 32x10R15 tires to our otherwise stock unit, and headed for the vast, unforgiving California deserts of California City.
