i would make sure you have a good spare and can get ti on and off,,,that is one rough road,,the one time i was there, another couple in a lexus suv, had a flat right at the track end,,, they tired to fix it, bit before they left there hometown, they had there tires rotated, etc. well they put the lugs on tooo tight, and the little keyed groove lug buster wouldnt let them take off the tire rim,,,had i not been there, they would have been stranded for an unknown period of time,,in 2004, there was NO cell service to call for help,,
i had to pack them in my PU truck, and all this large format stuff,, and my stuff,, haul them all the way back to the main fuel area, about 40-50 miles, then back to my campground backnear the start fo the trek to racetrack,,,they had to hire a tow truck to get them out, the next day,,,
point is,, make sure you have working back up, water, food, etc in the event you get stuck,,,
its a lonely place there,,
