You couldn't be more wrong.

The tire pressure stamped on the sidewall of a tire only tells you what the maximum amount of pressure that tire will hold. It tells you absolutely nothing about what tire pressure is recommended for your car.

I clipped an article from an automotive trade magazine that discussed this issue.

It speaks to the confusion regarding what is the proper tire pressure - what is stamped on 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.

I think I should be offended at this comment because I am a "tire person" and I do know my "stuff" ... but the book you are referring to is called a tire guide and the rpessure recommendations in the tire guide is supplied by the vehicle manufacturers

Time to enlighten these people on your darkest secret.
Okay, I'll do it for you.

If you inflate your tires with Helium ( lighter than air ), your car will float down the highway, which will extend tire life by 200 %.
People that make & sell tires just don't want you to know this.

and in the fall you should let all of the air out of your tires and replace the used summer air with fresh winter becasue as science tells us cold / winter air is denser than hot / summer air

Luke,

My intent was not to offend you, because you are obviously dedicated to be well informed. You will note that my point was that many or most in your profession do not take the time to learn their job. I am a professional mechanic and pride myself in the fact that I not only served an apprenticeship many years ago, but that I also continue my education by constantly reading professional journals. I have a friend who is a scientist and works for Berlex. She reads journal publications constantly, so why should our professions be any different. My profession is also plagued by folks who get a box of tools together, fix on cars for awhile, and call themselves mechanics. If you look at any profession, the requirements to be good come from a balance of formal schooling and on the job training. That goes for everyone including physicians. Would you want someone who handed in all his or her homework and got an A on the test cutting on you? Unfortunately there is no testing and no standards in our industry so we must tolerate mediocraty.
