The tire pressures on your gas filler door recommend two tire pressures: one for minimum load, and one for maximum load. I don't know how many pounds constitute a minimum load or a maximum load.
Nevertheless, the "minimum load" tire rating is 27 psi front, 27 psi rear.
The "maximum load" tire rating is 28 psi front, 33 psi rear.
I'm willing to bet that your two little girls probably fall comfortably in the minimum load category.
I generally am in the car by myself with no passengers, but I still run 28 and 33 psi.
I clipped an article from an automotive trade magazine that discussed tire pressures.
It speaks to the confusion regarding what is the proper tire pressure - what is stamped on the sidewall of the tires, or what the decal inside of the door or on the 'B' pillar says. Following is an excerpt:
"The Rubber Manufacturers Association told federal regulators that those pressures stamped on the sidewalls of tires should be eliminated. They are, simply, the maximum inflation pressure for the tire but are a "source of misinformation and confusion" for consumers, the group said.
Donald Shea, RMA president, went on to explain that "the current listing (on the sidewall) of the maximum pressure on tires is not the recommended normal inflation pressure."
Rather, you should use the tire pressure recommendations found on your vehicle's decal - also in the owner's manual for your vehicle- to properly inflate your tires. These figures are determined specifically for your vehicle and take into account your vehicle's weight, handling characteristics, etc."
