S637 ST

Regional All-Position

The S637 is a versatile regional all-position tire, featuring five extra-wide ribs for exceptional stability at all speeds. An extra-wide solid shoulder resists damage caused by high-scrub applications, while a mirrored tread design ensures even wear. Wide grooves are designed for hydroplaning resistance, while a long-life rubber compound is engineered for extended tread life. ST sizes featuring all steel construction are specifically designed for use in specialty trailer applications.

Features & Benefits
