Came standard on my King Ranch - very familiar with Pirelli, we have Pirelli tires on 3 fine German automobiles, including their respective sets of winter tires. These are quiet and smooth, even at highway speeds. Handling is superb in the dry and still pretty good in the wet. Sure they spin now and again when you pull away from a standstill in the wet, but it's a truck, with a suspension that has to cover a pretty wide range of loads. They do a pretty good job of handling everything from dry pavement to ice and snow, winter tires would be better in ice and snow, performance tire better on dry pavement, but they're a pretty good compromise, performing well across the spectrum. I'm used to changing my P Zeros at 10 to 15,000 miles, so I'm delighted these are only partially worn at 38,000 miles. They're coming on for 4 years old, I might need to replace them before they wear much more, mainly because of the rubber aging and hardening. I'm a big believer in sticking with the brand that the OEM fitted, so I'll replace them with the same.
