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 rolling resistance, while the aggressive tread design significantly improves off-road traction without sacrificing highway performance. All traction, all terrain, all the time!

  • 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.

These are amazing tires. Grip dry or wet. Haven’t had them in snow but I’m sure they will be great there too. I’ve got about 8k on the tires and they still look brand new.

amazing tire, snow traction was not perfect but for the way i drive im surprised they held up as well as they did. i put roughly 50,000 miles and was forced to replace them otherwise i would not pass inspection. treadwear was awesome for the way i drive. when im not goofing off racing around i use the truck on a farm and have driven through everything from pavement to cow muck to silage and gotten stuck ONCE in approximately 24" deep cow manure. overall recommend this tire.
