Guys, different brand and even different model tires require different pressures. The door jamb sticker refers ONLY to the factory tires, and then thats Ford's recommendations. Read the fine print on the tires. It will either be 35 PSI or 44 PSI for most tires. Did alignments and front end work at dealerships for many years. We would get notices from tire mfgs all the time advising us to air up to max or close to it as called for on the particular tire. Remember the Explorer/ Firestone fiasco?

3 things happen when you run um low; cupping(noisy tires), accelerated wear, lower mileage. There is a bit of softer ride also, but mine ain't a caddi.
