Just put 4 new Michelin LTX MS tires on my 2000 Explorer XLS (2WD). What should
the tire pressure be? The tires say "consult owner's manual / max. pressure 35
PSI". The owner's manual says to follow recomendations on side of tires, so I'm
unsure what is best. The tire dealer put 37 PSI in the fronts and 33 PSI rears.
I run 100% on the highway, and occasionally tow a 2700 pound trailer.
I have seen stickers inside the cover of the center console. The sticker
MUST be there somewhere. I run my 94 with Cross Terrains at 3 pounds over
what the sticker says for non-high-speed pressure.

If the tire sizes are the same, and the same load range, as a rule the
pressures will remain the same.
It should be remembered that the pressures the mfgr gives is a
*recommendation*. The user can vary to suit particular loads or
desired ride characteristics.
I am not positive of this but am 75% sure....Ford told owners to use 30 psi
on all 4 tires regardless of the stickers on the vehicle. That was after the
Firestone fiasco. I had a '99 Explorer and always ran 30 psi.
My sister's `97 Sport has had Michelin LTX M/S, P235/75R15, for a few
years. Her tires say max pressure 35 PSI, same as yours. They also say
max load 2028 lbs, and treadwear 440.
My dad just got the *same* tires for his `98 XLT, but... I noticed that
his say max load 2183 lbs @ 41 PSI, and treadwear 500.
I just assumed the tires were improved sometime between the two
purchases. Did you get "old stock" tires? Anybody else got the higher
numbers on their LTX M/S?
If the tires are the same size and type, they will have the
same maximum load rating. Make sure they are exactly the
same size and type. For the P235/75R15 LTX M/S tries
Michelin offers both a regular load and an "extra load" P
P235/75R15 105S: Max load = 1844 lb @ 35 psi*
P235/75R15/XL 108S: Max load = 1985 lb @ 41 psi*
* - The maximum load rating listed here has been derated
because the tires are used in a light truck application. The
tire's sidewall shows a higher maximum load rating (based on
the industry wide P metric standard).
I believe if you scrutinize the two tires in your original
post you will see they differ in load rating (105S vs 108S).
My 96 says 26 psi. After the Firestone press, reading the new
recomendations, and switching to LTX M/S, I've ran 30 psi (using
recomendation from Tire salesperson) without incident. Decided to forgo
rotating tires, and have exteremely even wear of tires at 30 psi, from start
to end of tire life. By contrast, tire wear was diabolical at 26 psi,
despite following recommended rotations. Go 30psi for sure (at least).
My Firestones ('93 Explorer) were as hard as a rock. I got 95,000 when I
finally decided to replace them. They had plenty of tread left, in fact,
they just passed the state safety inspection, but I no longer felt safe,
since they were slick as all get-out on rainy roads. I think they put rocks
in the rubber compound in the batch I got.
At least lately, I have not worn any tires down to the tread
wear bars. The tread seems to last forever, but the tires
get noisy or bumpy or whatever long before the tread is
gone. I just replaced the OE Continentals on my Expedition
with Michelins. The tread on the Continentals looked great
even though the tires had 50,000 miles. However they bumped
(despite repeated balancings) and were very noisy. Changing
to the Michelins was like buying a new truck. Smooth ride,
no bumping, no noise. The tread might last forever but the
internal structure of the tire does not.
Those pressures are wrong (or you reversed the readings) front and rear. I
would run them at 30-32 lbs front and rear except when towing. When towing,
increase the rear pressure to the max load rating of the tire (35 lbs).
Note - all pressures are measured stone cold. Once the tires have been
driven on at all (or even sat in the direct sun) they will measure higher by
an unknown amount. Use an accurate gauge.
