Cooper Discoverer AT3 4S
Technology
- Features adaptive technology that uses a silica-based tread compound for an all-terrain grip.
- Micro gauge zig-zag sipes for added biting edges which gives improved traction on slippery surfaces and for stability on a dry surface.
- Open, five-rib design for improved off-road performance on the wet and dry driving surface.
- Snow groove technology traps snow in its tread using tooth block edges and this gives snow to snow contact, thereby getting better snow traction.
- Presence of robust two-ply polyester casing in its internal construction.
- Circumferential aqua vac channels and wide lateral notches help evacuate water from the contact patch thereby reducing the risk of hydroplaning.
- Two high-strength steel belts with single nylon reinforcement for better handling, durability, and stability when driving especially at high speed.
