These fall into the "More durable, with faster rolling characteristics" category. Pirelli is a rare find here, retailing from $89 to $118 with tax. If you are an aggressive rider with tire woes, these are considerably tougher than anything mainstream.

In my experience as well as standardized testing on the durable end of the tire spectrum, these get constant highest marks for speed and grip combination while remaining puncture free. For the more aggressive category of riding on desert technical which requires more protection than anything usually found at bike shops. Nobody hates trailside tire repair more than a tire tester. One indicator that these are different is that all of these tires will stand up and support their own weight freestanding, even the trail casings, all without the DH casing weight. I have not seen another 900g tire do this.
NOTE. An interesting difference with these tires is that they all have different SINGLE compound formulation, (or durometer). This is not advertised either, leaving the consumer to think that Pirelli uses one "Smartgrip" compound across the spectrum. A different approach than other manufacturers. Each has a custom formulation for its specific intended use, and they are all called Smartgrip. SIMPLE and smart, and singly responsible for what proves to be a tire that doesnt experience torn knobs or lose its grip after it is half worn.
-The Enduro R tire (rear specific) with hardwall casing fixes rear pinch flat problems without creating an anchor. I find that a Trail or XC casing up front is a good lighter tradeoff since the front tire is not subject to the same stresses.
-Trail (Prowall) H. H is for HARDPACK, Pirellis fastest tread and compound, a small block tread, most people will only use it on the rear, but can be used F-R for the fastest setup. 2.4 and 2.6
-Trail (Prowall) and Enduro (Hardwall) M. Pirellis most versatile tread designed for "MIXED" conditions. Popular up front with a Trail or Enduro R in the back. 2.4 and 2.6
-Trail (Prowall) and Enduro (Hardwall) R. A REAR specific tread that capitalizes on climbing and braking traction without excess rolling resistance. Can be used front and rear, but more common with M or S up front.
-Trail (Prowall) and Enduro (Hardwall) S. A tire suited for loose over hardpack as well as softer soils, the compound is a bit softer than the others, but still very tough. Can be used Front and rear, but commonly used on the front with the R in the back.
