Choosing the right tread

Multi-Lug / Zig-Zag — best traction in mud, snow, and mixed terrain; great for landscaping and utility work.

C-Block / Block — thicker lugs resist cuts and abrasion; built for demolition, hardscape, and rock.

Common applications

  • Forestry & land clearing: High-impact terrain demanding continuous steel cords and drop-forged links.
  • Landscaping & turf: Lower-disturbance work on finished ground — pair with a multi-bar or turf tread.
  • General construction & site prep: Daily dirt work, grading, and loading where balanced traction and wear life matter.
  • Mud & snow: Loose, wet, or frozen ground where an aggressive multi-lug tread clears and grips.
