I just put on a set of "E-rated" Carlisle tires on the Cruiser before the 1500 mile trip to minnesota. Discount Tire are some great people to work with...at least at my store. So far the tires have held up great, even with an emergency lock up due to some moron cutting in front of me in a lane shift area then realizing the traffic ahead had slowed and slammed on his brakes. Lucky the new superduty has an excellent braking and the intergrated system sensed the lockup and modulated the trailer brakes so I could still control almost 20K of truck and trailer. Based upon the vehicle and driving behavior it almost felt like one of those possible insurance scams.
