Another tire pressure question
Hey guys, sorry to ask another tire pressure question, but nobody addressed it.
I have a 2005 2wd F150, but I have 265/60/18 wheels on it. I noticed when I got my oil changed today that they had the tire pressure at 35psi, and noted that was the correct pressure. I saw that most of the discussions here said that a good pressure was around 40ish. Am I running to low?

on the drivers door jam, tire inflation is posted for oem tires.
all tire's have the max inflation on the side wall, more plys in the tire ( load range ) meens more PSI you can put in the tire, your tire size seems odd to me, also on the tire number of plys ( load range ) is indicated...IF you have a LT tire, 40 PSI ios fine, If you have a P rated tire, 35 over will blow out the side walls..

You don't say which tire you have, so I can't tell if they are Load range C or D. If C 38-40 would be fine. If D I would bump them to about 44-46. As these are aftermarket tires, probably with a different load range, you can no longer go by the door sticker. Start about where I said and adjust as needed for wear.

These arent actually after market.. These are the tires & rims that come stock on the 4wd Lariat. They are BFGoodrich Radial Long Trail TA's. I just transplanted them to my truck. I just wondered if the weight difference of the trucks would matter. Also, right now i'm sitting at like 33.5 psi. Is that about normal for cold weather? Because when it gets hot, I assume the air will expand ? and be about right?

Forget what I said earlier. Now that I know exactly what load range of tires these are, 35 would be about right. These are P series tires, basically large passenger car tires. If what was on your vehicle before were P series, you could start at what was on the door sticker for them. Size may make some difference, but not that much.
Also use the same pressure, winter or summer. The outside temp will make a little difference, but not a drastic one.
Edit - Looked again at the specs for the tire. 35 is max, you probably don't need it that high. I would try 32 - 33.
