New Tires
Hi Guys,
I put some Cooper Discoverer ATR's on my '06 F-350, 275-70/18E. The Coopers replaced the stock Conti's. Should I run the Coopers at the recommended tire air pressure per the door sticker or something different. Max air pressure on the Coopers are 80# cold.

I would stick with what the door stickers say. Unless you are going to do something specific like going on soft sand or dirt...etc... (need to drop the pressure) the door sticker pressure will be good. keeping it at the optimal pressure will give you the least rolling resistance for everyday driving.

Stick with the door sticker pressure unless you go to a different size.
Also, keep an eye on the wear. If you see the tires wearing in the middle, drop the pressure 5 pounds.
