Hope I'm not to late to reply. Front tires 10 - 12 psi, rear 10 psi. The store on the same side as park entrance sells everything you need to mount a flag to your tow point on front bumper. I'm sure those young men at the store would be willing to help mount it. Also remember to turn off the ESP completely, not just the quick press of the button. Hold it in while in park until odometer says ESP OFF. Have fun and try different gears till you find what works for you, you should be able to climb all the hills with little problems.
