After our mediocre mid day meal, we decided to take a backroad cruise on the Hell’s Backbone Road. Before heading out of town, I stopped at the minimart at the north end of town to check the tire pressure. I was suspicious of the left front tire, it looked a little low and the Jeep was pulling to the left a bit. Sure enough, it was about 10 psi low. I checked the other tires as well, and they were all different… not uncommon for a rental. I should’ve checked them sooner in the trip as I usually do.
