Re: Why Do Original Equipt Tires Rate So Low?
I would characterize my approach to inflation pressure as "slightly over is better than slightly under", but surveyors would classify my cars as "properly inflated".
And the impression I am getting is that since the advent of TPMS, the percent of cars with underinflated tires is around 25% - and perhaps less. Of course that depends on what "underinflated" means - and I use 10% as that value.
