Dual Soprt Tire,Dual Sport Tyre 90/90-21
Features
The model is a perfect intermediate to hard terrain tire with a strong high-tech 6-ply carcass design.
This model utilizes Keystone DSC (Dual Stage Compound) technology, which is a harder rubber compound on center of tread for inline stability and extended tread life, and softer rubber compound on transition and side knobs for maximum cornering traction.
An aggressive, reversible tread pattern and symmetrical knob design provide excellent traction in both directions. Large center lugs provide great hook-up on concrete start pads and during straight-line acceleration and dimpled transition knobs add bite.
1. Dimpled transition knobs for added bite
2. Symmetrical tread pattern
3. 6 pr. Carcass construction
4. Dual compound tread offers best traction and wear
Yeh, the bitumen is really only there to join the dirt together! With ideal spacing between the tread, this is the REAL "go anywhere" deal!
