that's fine, but not what shadetree meant, based on his sidewall max observations.

I also don't put me running 35 psi tires at 45 in the hyper category, since the 35 psi figure is so conservative to start with.

so there is some grey area certainly, but I would put 90 psi on a ~3000 lb car in the hyper category. and ~50 psi in the higher pressure category.

Main issue IMHO is john Q will think of tires as perfect balloon analogies where more psi will be bad, and anything with the term hyper is reckless.
