Ted , the tires are for the 2500, now that there are more replies to this, I think I'm more confused than anything else. I need a tire that will wear well, since we do tow a 30' trailer in the summer, and I want one that will be good in winter, this is my wifes truck, and she has to drive about 40 miles 1 way to work, I can't justify spending 600 - 700 on a set of tires that wont last 1 year, The LTX's have 35k on them and are worn out! I've heard of people getting great life from these tires, I wish I knew their secret
