Sorry, but you don't understand tires or the tire industry. There are
standards for a given size and type of tire. The pressure on the sidewall is
the maximum inflation pressure for the tire, but not necessarily the correct
inflatin pressure for any given application. There are industry standard
load vs inflation pressure tables for any given type (p series, lt, etc.),
size (P195/70R15, P335/65R16, etc.), and load rating (98, 105, etc.).

Sorry, but you are the one who is wrong. Your basic mistake is thinking
that it is a "44 psi" tire. The 44 psi pressure is not the correct inflation
pressure, it is the maximum inflation pressure. Ford doesn't recommend
buying a 44 psi tire or a 35 psi tire. They recommended a certain size and
load rating for the tires and a pressure appropriate for tires of that size
and load rating. For a 2004 Taurus, the standard tire was a P215/60R16 94T.
The P215/60R is the tire size. the "94" is the load rating. The "T" is the
speed rating. The Ford pressure recommendation is appropriate for any P
series tires of the correct size (215/60R16) and load rating (94 = 1477 lb).
The Harmony tire in the OP happens to have a maximum pressure rating of 44
psi. The maximum load rating for this tire is 1477 lb (and it actually can
support this weight with only 35 psi, the 44 psi maximum is to allow higher
pressure recommendations for substained high speed operation). A 2004 Taurus
has a curb weight of around 3400 lb and a maximumloaded weight of less than
4000 lbs, or less than 1000 lb per tire. I don't don't have a copy of the
load inflation table fore this tire size with me today, but I am sure that
the tries are rated to carry far more than 1000 lb each when inflated to 30
psi. One thing I did notice - the Haromony tires in the P215/60R16 size are
only "S" rated tires (112 mph). The OE tires were T rated (118 mph).
Please study the situation before giving out more bad advice. Start
educating yourself by reading the following references (I have copied
information from the major US tire manufacturers):
http://tires.michelin-us.com/care/tip1.html
"Recommended Pressure
"Always inflate your tires to the recommended pressure listed by your
vehicle's manufacturer. This information can be found in the owner's manual
and often on a placard located in the vehicle's door jamb, inside the fuel
hatch, or on the glove compartment door."
http://www.conti-online.com/generato...rt_rma_en.html
"Use the correct inflation pressure recommended by the vehicle manufacturer,
not the pressure listed on the tire sidewall....."
"....More than half of drivers -- 55 percent -- incorrectly believe that the
correct inflation pressure is printed on the tire sidewall." - clearly they
added this line for people like you!
http://www.goodyeartires.com/faqs/Inflation.html#1
"How much air should I put in my tires?
"Proper inflation is the single most important part of tire care. The
inflation pressure on the side of the tire is the MAXIMUM operating
pressure. It is not necessarily the right inflation for your vehicle. Always
use the inflation recommended by the vehicle manufacturer. You can find it
in your owner's manual, posted on the edge of the driver's door, on a door
post or on the inside of the glovebox door."
http://www.tiresafety.com/maint/maint_ipressure.asp - this is Firestones /
Bridgestones site:
"Vehicle manufacturers list recommended tire pressures for original vehicle
tires in the owner's manual or on a placard on the end of the driver's side
door or in the glove box."
http://www.coopertires.com/us/en/safety/TireSafety2.asp
"The Proper Pressure
......
"There is no universal "right" pressure for all tires. The proper
inflation level will depend on what tires you have, and it may even be
different for your front and back tires. To find the correct pressure for
your tires, look at the tire information placard that's mounted inside the
frame of the driver's door, in the glove box or inside the fuel door. You
can also get that information in your vehicle owner's manual and from your
tire dealer."
