you risk OVER STEER
and handling problems
as well as changing the geometry of your alignment
max pressure is the max pressure that the tire can handle
ALWAYS follow the AUTO manufatures recommended pressure
anything other than that is DANGERIOUS
jeff get some certification
u advice KILLS
canada has the best tecks
You're correct. I misread the post.
He should look in his glove comparment. Often, there is a sticker there. If
not, there should be info in the owner's manual (you might be able to
download it at www.ford.com) or buy one from your dealer.
There is a caveate on using the door sticker. There are a lot of Explorers
out there with 26 psi front and rear marked on the sticker. IIRC, updated
pressure spec is 30 psi.... in the interest of reducing rolling resistance,
the operating (cold) pressure can be raised.... I ran my Ex (a 92) at 35 psi
for the entire time I had it with no drivability or handling concerns.

Auto Manufacturers recommended pressure is always a compromise between
ride, economy, handling, OEM tire dynamics and Safety. (Though
Firestone and Ford may disagree on that issue).
Inflation levels are based upon requirements. Fast driving in hot
climates require higher pressures than slow driving in cold climates.
Off road conditions require (in some circumstances) even lower
pressures. Add to that tire age, tire manufacturing specifications
and driving style & you've got an idea of how dynamic the whole
IF economy is key, higher pressure, if Ride? Lower pressure, if
handling specific to each tire & the road surface it's traveling on.
Manufacturers spec is a good starting point. Sidewall max is fine.
Years ago when the older tires would flat spot over the winter we'd
run them up to 60 PSI and run them for a few days (not idea but helped
them last another season).
Like with anything else, what do you need the tire to do? what's it
capable of? where are you going to use it? Based on that make your
Also.. Are you inflating with a Pure Nitrogen or a 78% mix with
who designed the car
ford or the tire guys
ford picked tires capible of certain specs
and what pressure does teck use to set alignment
what a tard
cars are built with UNDERSTEER in mind
next time you buy a van
some are not designed to be ambulances ETC
why is that
they are all f 450
what is the diffrence
also why do schoolbusses
police cars, ambulances
use RECOMMENDED SPECS as per FORD

Who designs the tires? We are talking about tires here right?
Did Ford 'OK' the pressure recommendations with Firestone before the
Disastrous results? Ford tried to use Tire noise & under steer to
accommodate a substandard chassis design.
The pressure the vehicle will be run at. Assuming that the "teck" or
"tech" has enough of a clue to ask the operator. Alignment is
designed to be able to be adjusted to accommodate a multitude of
conditions. (including tire pressure). Some vehicles even allow for
spring loading adjustments to really fine tune the suspension.
(read a book or two, you might learn something). Yes MANY
conventional passenger vehicles are designed with Under steer in mind.
Other vehicles are designed with a Neutral or even over steer profile
depending upon the expected driver competence level. Under steer and
over steer can be radically affected by tire pressure as well (hence
the importance of answering the OP accurately, instead of blindly
flailing at the keyboard. Also vehicular loading can affect vehicle
dynamics, this can be mitigated with differentials in tire pressure.
Renault, Mercedes, GMC & Bedford make F450's?
Could you provide me with your source. I've yet to see a F450 Bedford
Ambulance. In fact I also believe that the Transit has never had the
classification F450 Perhaps it's a prairie thing...............
what is the difference with "____________" Looks like you're starting
a sentence here but...........
You're making a HUGE assumption there kid.
Some municipal authorities may follow manufacturers "guidelines"
Many don't. Maine & Nevada are likely to use differing pressures to
adapt to their unique environments.
If you doubt my viewpoint (and it's quite likely you do). Ask a few
rally teams what pressure they set their tires at, Then ask a few Indy
teams, then ask a few Nascar teams.
Then call up Ford & ask them how they arrive at the recommended
pressure guidelines. You might find the answer goes something like
this: "it is a compromise designed to match ride/handling dynamics
with the "average" driver" for our street vehicles.
NOTE: when you're making 1 million plus vehicles you design it for the
"common" good, not the individual ideal. That's up to the driver.
In this case the OP wanted to know what was ideal for his situation,
not what would be good for a crown Vic parked outside a grow-op in
See, we in the outside world do sometimes hear what people in Alberta
do when they're not living in their parents basements surfing the NG"s
or digging in the Tar fields.
Remember this; Jesus loves you, even though
everyone else thinks you're an as shole
Yes... I check all four tire pressures before adjusting them..... some
prefer softer tires for ride (look for underinfaltion wear).... some
occasionally haul heavy loads and require hgher pressures (look for
overinflation wear).... equalize the pressures side to side to avoid tire
height induced changes and the alignment is good to go.
Making unilateral changes to a vehicles tire pressure for no other reason
than "they don't match the sticker" can induce the wrath of the customer.
