That's great, Dave. I consider the Diamondbacks to be the best tires I've ever had on my Coupe de Ville over the last 23 years (probably about 3 other sets of various Cokers before these)
Post some pictures of your truck with the new tires.
And thanks for the tip about Summit selling DBs with free shipping. A friend of mine out in California just ordered a set from Summit and saved $100 as a result.
