I have a Toyota T100. I bought it used without a manual. According to
the sticker on the doorframe about the max load, the front tires should
be at 26 psi and the back tires at 35 psi. On the tires themselves, 50
psi is recommended. Which number should I go with?

Thanks,
Trevor

The one on the sticker. The pressure quoted on the tyres is the maximum they
can take and not related to the application (vehicle they are on).

The numbers on the door frame.

The numbers on the tires themselves are the max pressure for the tire when
it is at the max loading. The tire can carry more than the truck. If you add
the vehicle weight and the payload weight, you get the Gross Weight.
Assuming each tire will be loaded with 1/4 (not a perfectly accurate
assumption, but close enough for the purposes here), you will find that the
gross weight is far less than the max load that the tire can support.

Use the number on the door pillar, you will get a more comfortable ride and
longer tire life. Having said that, since tires are prone to leaking over
time, I generally fill mine a few pounds high because I don't bother to
check them again until they look low. By the time they look low, they have
been low for a while, and everything tends to even out.

If the tires wear more in the center than on the edges, you fill them with
too much air. If they wear more on the edges than in the center, you do not
have enough air (assuming the alignment is good).

What Jeff said. Also, you can run a simple test for yourself that will
take into consideration the load that the tire is carrying. If you take
chalk and make a heavy line across the tread on each tire and then run it
on pavement for a bit you can see how the chalk wears off. You want it to
wear off evenly across. If it is only worn in the center you have too
much air for the load; if it is worn on the edges you need more air.
Adjust the air pressure and try it again until you have an even wear
pattern on the chalk.

I do this periodically and get nice even wear until it is time to replace.
It can be especially helpful for those times that you overload the vehicle
and wonder about the tires.

50 psi is NOT recommended 50 psi, for those tires, is the MAXIMUM allowable
pressure.
