Proper Tire Pressure

you run the max pressure? that's not what you're supposed to do

i've been pretty bad wear on the outside edges of my front tires. Not sure if it's an alignment issue, a PSI issue, or a just a truck-thing.

 

So I just got some used (guessing %70 left) Michelin LT245/75/16 for about $250.
From reading the thread I think I'm going to go to the 29lbs recommendation on the badge.
07 Taco double cab 4l
Hard roll top, with a rack
I carry maybe #200 of tools regularly
My two girls and I are the common passengers.
I carry up to #300 on the rack occasionally with maybe an extra #100 in the bed once or twice a month.

Should I make any adjustments for the LT tires or for what I carry?

Also, I got new sensors on Amazon which work until I get on the highway, then I have to use the tire shop reset, so I think one is bad, can I register the TPMS myself, if I have a bad sensor and have to swap?

 

If your stock tire was a P245/75/16/109 @ 29 psi, your adjusted pressure for a LT245/75/16 is 41 psi.

 

The Max number on the tire has nothing to do with your Toyota, and the number inside the door jam has nothing to do with the tire (presuming your Tacoma didn't come with them from the factory). The ONE and only best way to find the ideal pressure for your daily driving is to do the CHALK TEST. https://www.tacomaworld.com/threads/chalk-test-dynapro-atm-at-16-000-miles.226635/
