A drive tire with open shoulders would stand a better chance, but not by much. You did the right thing by scouting out the area first, I've done that the odd time. As long as you can keep moving you have a chance but as soon as you stop on loose sand, you're screwed. You need a really wide low inflation tire to run on sand for an extended trip. Letting the air out of the drives down to about 35 psi can help, as long as you can fill them back up. http://www.tirepressurecontrol.com/oilfield.php
This was behind the chevron in Coachella CA exit 146 I-10. To those saying trucks with highway tires should stay on asphalt not everyone goes from grocery wharehouse to grocery wharehouse. Go pull a skateboard for awhile and you'll find yourself in plenty of places that were never designed for a truck.
Ok. Hhmmmm sand. Since I have alot where I live in NEVADA Unless you have this And this, don't go into sand I have these and don't play in sand to many times I
I don't think it's actually truck parking but at midnight on I-10 you put it where you can. I still had 30 mins on my clocks if it wasn't feasible but I checked it out and knew I'd been in a lot worse in the oilfield so I took it. Plus it was close to del taco so I had to make it work.
