S637+

Steer Tyre

The S637+ is a versatile all-position tyre for regional use featuring five extra-wide ribs for exceptional stability. An extra-wide solid shoulder resists damage during high-scrub applications, while a mirrored tread design ensures even tread wear. Wide grooves effectively improve wet performance while the special tread compound improves tread life.

 

Features & Benefits:

  • Tread sipes improve traction in wet conditions and allow the tyre to
    run cool to extend tread life.
  • Shallow tread design reduces rolling resistance for better fuel
    economy.
  • Unique tread wall grooves and sipes help reduce irregular wear.
