Installing TPMS sensors on my brand new F-450 truck

I think your getting good recommendations here Mitch. The tire pressure should be set to the pressure listed inside the door sill. Also there are long/reverse air knozzle that can be used to access the valve stem.

I must say I'm impressed with the factory TPMS and back in Sept. when driving home from a fishing trip my center display flashed a low tire pressure warning. So I pull over at my earliest opportunity and sure enough there's a screw in my front passenger tire and the air is literly blowing out.
