Reply to "Tire Pressure again"


@Michael McKelvey  Easy process:  get a piece of driveway chalk and draw a 1” wide line all the way across your tire tread, sidewalk to sidewall, on your tires.   Go out for a typical drive ( “don’t drive like my brother” ).   When you get home ( or home equivalent ), inspect your tires to see how much of the chalk is now gone.  
You should, ideally, see about 80% of the chalk width versus tread width gone, all across the tread width.   Less than that says your tire pressure is too high ( the tire is too hard ).  Wider than that, the pressure is too low, especially if the chalk towards the sidewalls is gone but the chalk in the center is still there, showing that the tread is “pooching” up in the center.
