35 is too much for me. I was always taught a default air pressure setting for cars is 32. But even this seems a bit rough for me, and 29 felt a bit soft and sloppy, so I've settled in at 31.
I wondered how these NASCAR drivers could tell a one pound difference in their tires, but you really can, if you get used to what your car feels like.
NEVER inflate to the sidewall # - read carefully, this is the maximum pressure. A violent blowout could occur.
