Outstanding grip on mud, sand, and gravel
The SL366’s variable shoulder blocks are engineered to maintain optimal road contact, even on soft or uneven surfaces. Whether you’re driving through sandy trails, gravel roads, or muddy tracks, the tread design ensures superior grip and stability. This level of traction allows drivers to remain in control, even under extreme conditions. That makes the SL366 a perfect match for off-road enthusiasts and professionals who demand performance in rugged environments.

Unmatched traction across all types of terrain
The exclusive Multi-Step Tread Blocks technology delivers consistent traction on any surface. These multi-level tread blocks increase the contact area and enhance lateral stability, while promoting self-cleaning of the tire. Whether you're navigating through mud or climbing over rocky paths, the SL366 keeps performing. Its ability to adapt quickly to changing terrain makes it a powerful ally for both adventurers and everyday workers.

Significantly reduced risk of hydroplaning
Thanks to the Deep & Wide Grooves, the SL366 ensures quick and effective drainage of water, mud, and even slush. This feature dramatically reduces the risk of hydroplaning, especially in heavy rain or on wet pavement. Beyond improving safety, it also helps maintain excellent handling at highway speeds. This advanced drainage system is part of what makes the SL366 not just a durable off-road tire, but a smart and secure choice for mixed-use driving.
