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
- Mud & snow: Loose, wet, or frozen ground where an aggressive multi-lug tread clears and grips.
- Landscaping & turf: Lower-disturbance work on finished ground — pair with a multi-bar or turf tread.
- Demolition & abrasive surfaces: Concrete, rock, and rebar — a block / C-lug tread resists cuts and chunking.
- General construction & site prep: Daily dirt work, grading, and loading where balanced traction and wear life matter.
