I'm a new jeep owner, I have 2010 Jk Sport and I took it to the sand dunes yesterday. I looked like such the newbie. Other then airing down the tires and putting it in 4wd is there anything else I was supposed to do? Also when I aired my tires back up to 35 psi my low tire light is still on. Anyone else have this problem? Anything I need to do today to get it back to normal driving condition other then spraying out the bottom where sand might still be?
