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.

Variable Density Nylon Technology

Nylon is strategically positioned and applied in a manner to resist flat spotting for improved ride quality and a balanced, even tread wear for longer tread life.

Ventless Technology

The molds used to manufacture the A/T3 incorporate a venting technology that eliminates micro-vents in the tread area. This ventless technology provides a crisp, clean, premium appearance.
