26 PSI Could that be right?
markmd
The tag inside the drivers door on my Explorer states the tire pressure
should be 26 PSI. For some reason I think thats low and the tires would
look flat. The dealer had them at 34 PSI. Any comments? Also it's my
understanding is that every tire should be graded as far as speed (A,B,C) ,
traction (A,B,C) and treadware (100-400). However I must be going blind
because I can't find the ratings on the Firestone Wilderness AT tires. Any
help here?
Thanks in advance.

light truck and larger tires are not required to have to dot ratings on the
tires

Iposted this same question and many say 26 is correct but most run 28-32
depending on the ride comfort . Most seem to prefer 28psi

I ran the 26psi for a bit, found excessive wear on the shoulders of the
tires in the first 5000 miles. I've been running 30psi since with better
results albeit a somewhat harsher ride.

Then how about this scenario....
I've got a 92 with Pirelli P300s (yea, I know...<G>>>>). The tires are NOT
exactly the best in the world, but I'd like to get some mileage out of them.
The problem is that after sitting overnight, they develop flat spots and
ride very rough until warm. Well, at least that's what it feels like.
Would going to a higher pressure keep this from happening?

Well, I have the same tires and they were at 26psi when received from the
dealer and still are at 26psi and they do not look flat. Are you checking your
tire pressure cold or hot? The 26psi is based on cold tires, I believe you add
4psi if checking the tires hot. Hope this helps.
