Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for Jeep Wrangler JK. Your Jeep Wrangler JK may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
