Why 2 different tire pressure stickers?

Chalk line test. The trucks OEM set those pressures with the truck set at THEIR parameters. You have added stuff (even just a little bit matters) and you know your driving style and the local conditions. Find ideal with a chalk line and adjust from there.

Don't assume that the OEM is automatically correct, even more so if you swap to tires other than what the truck came with.

 

Want to add something.

Toyota sent a letter (at least I received one) saying that if your tacoma have trd wheels and LT tires then you have a wrong tire pressure decal and should take it to a dealer to put the correct decal on it.

Mine came with the Rugged Trail tires, which I don't remember if they are "P" or "LT".

Now I put BFG "Mud Terrain" which are LT, and if I put 29/32 it will vibrate a lot. Put in higher pressure, don't remember how much at a tire shop and the vibration goes away. Also the "Mud Terrain" max pressure is 80 psi.

I have a 2013 TRD Off-Road 4x4

 

Factory put the extra sticker on by mistake...you think? The lower pressure would be for P rated tires, the higher pressure would be for LT's like the Baja and Pro. LT tires usually have a higher load capacity rating, but if inflated to the P rated pressure actually have a lower load carrying capacity...hence the sticker for a higher psi. You have two sets of stickers covering several sizes & ratings of tires...read your tire size and type and use the factory recommended setting for that tire.

 

The OP's vehicle description lists a TX Baja. He should verify that he has the LT tires, then follow the 46 PSI recommendation. Or do the chalk test.

Sorry ... ^^^^ what he said.
