I just got a new set of Pirelli Scorpions for my 99 RAM2500 CTD. From Discount Tire. Previous set of same tires performed well until tread wore out. Excellent tires. A little softer rubber than Michelin, which I like because it smooths out the ride a bit. Don't last quite as long as Michelins (because Michelin uses _very_ hard rubber), but they cost a LOT less. These have two nylon "cap" plies on top of the steel belts, to reduce danger of tread separation. I strongly recommend NEVER buying a truck tire without cap plies. Learned that lesson the hard way when a Goodyear Wranger ripped apart on the highway and caused a lot of damage. Good luck!
