How far over MFR recommended for pressure is ok w/o destroying tires?

First, I am not a fan of using elevated inflation pressures, but I understand why some are.

Second, there isn't a solid answer to your question. Some folks have reported center wear on elevated inflation pressures below the max pressure - and some have reported even wear on considerably higher pressures. I think this means there is some additional factor driving the wear (in addition to the inflation pressure) .

I would urge caution. There have been reports of traction issues as well when using elevated inflation pressures.

Sidewall max in the winter 5-10psi over in the summer.
