Pirelli Scorpion Trail S

The Pirelli Scorpion Trail S is the soft terrain specialist of the Scorpion Trail range, built for aggressive trail riding when conditions turn loose. Its tall profile and widely spaced tread pattern cut into and hook up on any kind of loose or soft terrain, from dry loam to sticky mud, delivering the grip and reliability that soft conditions demand. Equally at home on trail bikes and downcountry setups, the Scorpion Trail S is the right call when grip is the priority and the trail is anything but firm.

At 930g in ProWALL configuration, it sits significantly lighter than the HardWALL Enduro S while sharing the same soft-terrain tread design, making it a strong choice for riders who want aggressive grip without the added weight of a full enduro casing. The SmartGRIP Compound delivers consistent grip across dry and wet conditions alike, backed by Pirelli's motocross and rally compounding heritage.

Decades of victories in Motocross and Rally competitions around the world led our engineers to the development of a new innovative rubber formulation: the SmartGRIP Compound for the Scorpion™ MTB which blends together opposite features:
- Tear resistance for the maximum mechanical grip on dry and wet surfaces together with the maximum resistance against punctures;
- Chemical grip on wet terrain for unconditional riding in any kind of weather;
The SmartGRIP Compound is the result of an extensive process of research and development that led us to absolute performances in either dry and wet conditions. We chose a single compound formulation in order to achieve the most consistent performances throughout the entire lifespan of the tyre even when the knobs start to wear off.

The ProWALL features a sidewall protection that enhances the puncture resistance and the handling at low inflation pressure. The sidewall is reinforced with an extra layer of nylon that increases the resistance against penetration and cuts while stabilizing the tyre at low inflation pressure for a confident ride over any kind of terrain. The ProWALL is a solid option for XC racing, trail riding and enduro when paired with different carcass constructions, namely of 120 and 60tpi.

Our thoughts:
The Trail S punches well above its weight for a soft terrain tire. The ProWALL casing keeps things light and lively, while the soft terrain tread does genuine work in loam and mud without dragging on hardpack the way a heavier, taller tread would. The downcountry compatibility note from Pirelli is worth taking seriously: this is a tire that works for riders who want aggressive traction without locking themselves into a heavy enduro setup. If your local trails are soft and your bike is on the lighter, more pedalling-oriented end of the spectrum, the Trail S is a smart choice.
