Discoverer A/T3

Product Overview

Standard Limited Warranty
55,000 Mile Tread Wear Protection

The Discoverer A/T3 utilizes a balanced combination of technology, compounding and design to produce a tire that will perform well in nearly all types of terrains. The tread compound enhances wet traction and reduces rolling resistance, while the aggressive tread design significantly improves off-road traction without sacrificing highway performance. All traction...all terrain..all the time!

M + S Rated

Modern, Aggressive 5-Rib All-Terrain Design

The aggressive all-terrain design is engineered to provide outstanding performance in both on-road and off-road driving applications. The A/T3 tread pattern exploits a combination of features specifically suited to provide solid all-terrain performance, superior all-season traction, excellent stability, confident handling and reliable tread wear.

Silica Based Tread Compound

The tread compound is formulated with a chemically coupled silica and carbon black mixture that provides excellent wet traction and handling on the highway, while also improving cut and chip resistance in more harsh rocky and gravel terrain. The silica enriched tread compound has lower rolling resistance than traditional full carbon black tread compounds.

Dual Draft Tread Element Walls

The dual draft angles on the tread element walls aid in reducing stone retention, stone drilling and assist in cut and chip resistance.

Lateral Groove Protectors

Serrated steps in the lateral grooves of the intermediate tread rib reduces the chance of stone retention and stone drilling.
