I got a coupon from the Les Schwab tire co (big in the great northwest) for a free tire rotation. After the rotation, started noticing my steering wheel was just a touch off center on a level road. Checked tire pressure: two left tires at 30 lbs (where I set them) and right two tires were at 40 lbs.
There are a few lessons to be learned here. Have never understood why people think more air is better.
Always check your tire pressure after a service!

I have 2 vehicles to go to my local Toyota dealer for regular service. They both always come back with air pressure at 35psi no matter what the door jamb sticker says. I know this and go out immediately and reduce the air pressure to the recommended #.

i always set mine to 35 for fuel economy.

i do keep an eye on tire wear, and after 5 years of 35 PSI, i have never had the center worn out on my tires.

My tech sets the tires at 35psi in the winter months and 32psi in the summer. The logic is that the temperature in the garage is typically around 30° warmer than the outside temp in the winter. (35psi @ 68°F inside = 32psi @ 38° outside)

Tires should be checked and adjusted regularly as conditions change. 1 psi is gained or lost for every 10° temperature change, whether using air or nitrogen.

Good read on nitrogen vs. air for those curious: http://www.tirerack.com/tires/tirete...jsp?techid=191
