What is highest PSI in tires you have used?

There is likely no specific data on over inflation, just like there is no specific data on under inflation...however, the lack of numbers should not alleviate one of the responsibility of using ones brain when determining a good idea vs. a bad one. There are no positives(outside of a race track) for running dangerously high tire pressure, and there is no published data available to back your claims that it's a good idea.

You're fighting physics and common sense, neither battle will end in victory.

NHTSA's current crash files do not contain any direct evidence that points to low tire pressure(or high pressure) as the cause of any particular crash. (19) However, this lack of data does not imply that low tire pressure(or high pressure) does not cause or contribute to any crashes. The agency believes that it simply reflects the fact that measurements of tire pressure are not among the vehicle information included in the crash reports received by the agency and placed in its crash data bases. (20)

The only tire-related data element in the agency's crash databases is "flat tire or blowout." However, even in crashes for which a flat tire or blowout is reported, crash investigators cannot tell whether low(or high) tire pressure contributed to the tire failure.

The agency examined its crash files to gather information on tire-related problems that resulted in crashes. The NASS-CDS has trained investigators who collect data on a sample of tow-away crashes around the United States. These data can be weighted to generate national estimates.

The NASS-CDS General Vehicle Form contains a value indicating vehicle loss of control due to a blowout or flat tire. This value is used only when a vehicle's tire went flat, causing a loss of control of the vehicle and a crash. The value is not used for cases in which one or more of a vehicle's tires were under-inflated, preventing the vehicle from performing as well as it could have in an emergency situation.

Somebody had to input common sense into this thread, so random people searching the net don't see this thread and thinks it's a good idea to copy you folks.

These studies were after the fact, thats why they couldn't directly relate to tire pressure. "Either low or high pressure" is a wide spectrum. I respect that you have experience in the subject, but R2, others, and I haven't exactly blindly upped our pressures. Not speaking for the others but I've read the various forums... I haven't read about any incidents related to overinflation. People have done this for at least 5 years now, of that population of people doing this, I have not heard of any incidences. It's not to say that it proves my stance, it's saying that without direct info/studies, that is what I have to go on.

I do understand basic physics, you're saying something will give. Of course something will give, but the picture most people think of in their mind about tires popping is like that of a overblown balloon. It's not going to pop like a balloon. I've had a few punctures...at the high psi (granted at low or no speed), they don't "pop", otherwise I would have been scared shitless. What a majority of us (those who do over inflate) are saying is that there is a higher limit than what's on the sidewall.

Then there are the many differences on the max psi for different tires. Manufacturers have come out with 50psi max tires in their "fuel economy" tires. Those manufactureres haven't exactly explained what is so different, or what they did to "provide safety" at the higher psi.

Someone please scientifically test this out for us!?! We are not unreasonable, we will take data.

There is a lot more damage out beyond YW for the brainless copy cats. For the most part if someone asks me, I tell them to do the max on the sidewall and only as high as they're comfortable with, and I'll find out later that they stopped at 5 under the max. Why do I do that? The folks who usually ask this question just want confirmation for what they already know and don't really want to be scared. Now if someone gave me a hint that they knew some basics about hypermiling, I would steer the conversation a different direction.
