those stock goodyears that come on our 20" rims call 44 max I run at 40 cus it feels spongy an wears faster at manf. specs I got 55k out of orignals bought same to replace only three though used spare as new to cheapin the blow was in wy an they were expnsv (250 ea) wanted some nittos or smthng better but no money for that at the time.

 

Ummm, yeah, I CAN read, especially where it says "maximum whatever PSI". That gives you a good guideline, as long as you stay a little under the max as set by the manufacturer, and match all 4 to that pressure, then you get even wear all around (especially with regular tire rotation). Only the "hello" part was sarcastic. I trust those door stickers about as far as I can throw the truck, as mine lists only the stock 17" size, and not what is on the window sticker/option list that shows the 20" stuff mine came with.

 

I have found that the truck drives best when using the pressure recommended in the door jam. Same as with other vehicles. Running more in the front usually tends to make the vehicle wander around on the road a bit.
My OEM Good Years are wearing fine. They have 21K on them and have a lot of tread left. Always run @ 36psi.

 

Doesn't matter for me (as some others I'm sure). I don't have stock tires.
