Higher tire pressure and winter handling?

[1stToyota]

Last year a guy here [can't remember which member] did his own private test on a parking lot. He hit the brakes with the proper amount of air, then pumped up the pressure and retested. His conclusion was that the extra distance he traveled with the extra pressure could have been the difference between wrecking or staying safe.

I've always heard that you let a few pounds out in winter to get maximum traction, so yeah, only makes sense to get double the psi in those tires! Might save a few cents at the next fillup.
