I just put a set of Firestone Destination A/T on my 2006 F150 Supercrew FX4 5.4L.

The door sticker says to keep tire pressure at 40 psi front and back. Firestone says tire pressure should be 35 psi.

Who should I listen to?

What's it say on the sidewall of the tire...max tire pressure cold ...the door sticker is for the tires that came with your truck...not the ones you just put on...unless they are the same tires.

 

The tires say max psi is 44.

 

I would go with 40 ...my max is 60psi and I run 50 in the summer and 40 in the winter

 

Thanks Mark, I'll put 40 in the tires.

your welcome steve...
