I just bought new tires on larger rims for my `87 King Cab.
The stock tires where P195/75/R14 and the tire pressure
on the sticker by the doorframe was 26 PSI (for those tires).
The new tires/wheels are P215/75/R15, but I don't know
what the correct tire pressure should be. The guy at
the tire dealer said just to keep them inflated at 35 PSI, which
is the maximum pressure for those tires, so I'm pretty
sure he has no idea what he's talking about. That is
I know from my factory manual that the 4X4 version
of the truck was available with this size tire (mine's just RWD).
Would someone be able to check on their truck and
see what the correct pressures are for 215/75/R15 tires?
Thanks for any help!
It says 35 PSI, but almost *all* tires say that. That's
the MAXIMUM inflation pressure for the tire, without
reference to the vehicle. It's a WARNING, not a
My old 14" tires said the same, 35 PSI, but the sticker
on the truck says the 14" tires need to be 26 PSI, generally.
Big difference. 35 PSI is definitely over-inflated.
What I need to know is what the correct inflation pressure
is for P215/75/R15 tires on a King Cab.
it depends... are you hauling heavy loads if so then 35psi is not
hell on my f250 it says inflate to 80psi i have them at 60
of cource the f250 is for heavy loads.... however its really user based
i would go with 30psi just because thats what i kept all my cars at actually
more like 32 - 33

Yes, 35 psi is the maximum rating, but you want that if you were carrying a half
ton. I agree that 26 psi is too low, and I wore out the P215/75R14 General
factory tires in 15K miles going by the placard 'recommended pressure'. I think
the low psi recommendation is for a smoother ride more than anything else.
I also have a Kingcab V6 2WD and now run 34 front, and 30 rear (unloaded) on
P225/60R16 tires. If you have a 4 cyl, then maybe 32/30 F/R would be a starting
point. Correct pressure depends on the tires, but generally too much pressure
wears out the tread in the center first, and too low wears off the edges too
fast. Also with too low of a pressure, the tire loses the ability to shed heat
efficiently, which leads to shorter tread life and could be dangerous.
Huh? Guessing is definitely not necessary. Frankly, I'm a little
surprised that nobody has come up with the answer yet. Does that
mean everyone is driving around on incorrectly inflated tires?
I'm beginning to wonder.
According to my factory service manual, in 1987 Nissan
sold the 4x4 regular and King Cab trucks, as well as the
Pathfinder in E and XE trim with P215/75R15 tires as standard.
Therefore, each of these vehicles would have a plate on the
driver's side door pillar, or a sticker in the glove box stating
SPECIFICALLY what the inflation pressure is for THAT tire
on THAT vehicle. No guessing involved.
I assume this would apply to later years for trucks with same
size tire, as well.
