I was looking at getting my new set for the F350 from Sam's. Priced them and they beat everyone around me with an out-the-door price. Tires is tires and as long as one gets a set with a current DOT date they should be OK. (I always specify that I will only accept tires with DOT build dates within the last 30-60 days.) My only concern is the quality of the balancing, etc. As far as lugnut torque and tire pressures, I always check them anyway before leaving a tire place.
