I just had new tires put on my 2004 F-250 and on the bill I had to sign that I would retorque the lug nuts after 30 miles. The bill states that they torque to 115 foot pounds. In my Haynes manual for the Ford Super Duty it recommends 155 foot pounds torque for 2003 and newer Super Dutys. What is the correct torque number? The mechanic that installed my wheels says 140 foot pounds max. and 115 to 120 foot pounds that they use.I have been using the 155 FP number when I rotate the tires once a year,never had any trouble.
