It's probably a misguided attempt to decrease their liability.
I would say that is a true statement.

From the great State of California:

California has passed a new law requiring most auto servicing sites to check tire pressure at each visit and add air when necessary. The law will affect 40,000 businesses in the state, although the mandate does not effect body shops, car washes, glass repair shops, or parts stores. The state's government will let the service stations, smog-check stations, oil change places, and so on determine how much to charge for the check, and they must have a high-accuracy pressure gauge on hand. The tire pressure monitoring law will go into effect in July 1, 2010.


I'm tired of the government trying to manage every aspect of my life.

The recommended pressures on stickers are typically too high.

For 35" (315xx70x17 Mickey Thompson) I use 28~29 psi.

In the hot season, when I go through the desert, I drive for a while until the tires have warmed. Then, I lower back to 28 psi. (That's for roads. For wheeling it's obviously lower)

Last year (pretty sure last year) in one of the Magazine's was a great formula for calculating tire pressure. I would be happy to post it, except my sister spilled her coffee all over it and thus my copy is no more. So if anyone can find a copy and post it that would be great, or if anyone from Petersen's or one of the other's is on the forum maybe they can post it. Most of the magazine's are all owned by the same company, so help us out guys.

It worked out on my 35" km2's to be 32 lbs. and with all kinds of testing found that was the best pressure. The formula calculated the factory spec on the b pillar with information on the tire sidewall and bam, you had your number.

Even at 36 years old, little sisters are still the same.
