Because of the staggered setup and wide tires (275 or greater) you're experiencing a physics phenomenon called the Akermanns effect. The staggered setup increases the effect. In simplest terms it's because each axel has different turning radius. Happens almost every time I back out of my driveway. My driveway is inclined so it enhances it even more....nothing to worry about.
