There's a lot of talk here about poor ride quality and how that relates to tire pressure. How about we break that down and help each other from our own experiences A) Tell us what configuration your truck is for ref. SuperCab or SuperCrew Lariat, XLT or XL 4x2 or 4x4 FX4 ? B) Tell us what pressure you are running, if it's other than what's specified on the placard..... C) Post up a photo of your tire pressure placard... If we don't know what size tire is on your truck... your information won't be of much use to anybody.
