LT E tires from factory PSI

[BuschLatte420]

Just seeing if anyone here had a ram 1500 come from the factory with a E rated tire ( was a build option) and if so what the PSI recommendation is on the door jam sticker. Thanks!

The door sticker will still show the same psi rating as a non load range E tire. I believe it's 44 psi cold.

My '18 rebel came with AT2's, not sure off hand the rating, but it's 55 front, and 45 back. But like nlambert said, they likely don't "re-rate" the tire pressure for alternative tire styles.

My truck that came with P rated tires 265/70r17s said 40 front and back.

When I purchased my ko2’s bf Goodrich said to put 47 all around so I am rocking that currently. Truck is going to dealer for a few things including a steering issue so don’t want them blaming my tires that are still stock size but E rated and a higher tire pressure.

Dealer will probably just drop the PSI. Especially this time of year, tire PSI can swing 5+ PSI. I adjust my tires 2-3 times a year (avg), and check with the TPMS in the truck, and I have seen it start at 50/40, and by end of day driving around doing ****, plus the temp swings we get here, they can be almost 60/50.

I would just set it to what the sticker on the door says if you're concerned with what the dealer might say. But.... 47 psi isn't really a big deal. Now, if you had 80psi in there, that might be a different story.

If they fix my issue they can do whatever they want I can just fill them back up. Steering wheel has always been a hair to the left but truck drives and tracks good, but now in some left turns seems like the eps or something forces my truck to stay in the turn and I really have to manually correct it. Or like the eps moves the wheel when I put no input in to. Not good.

Don't guess, do the chalk test. Go to YouTube and search "Tire Chalk Test". That will set your tires at the correct pressure.
