Does This Tire Fit?

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.

I mounted Cooper Discoverer A-T3 tires (33x12.50x15) to my full size 91 Blazer K5 on the 15x8 stock aluminum alloy wheels. The 33 inch A-T3 tires look amazing on the alloys and are the best SUV tires I've ever owned. The truck handles extremely well in cornering on blacktop, sand and gravel. In snow I've almost become overconfident with this tire and have on occasion driven a bit too fast for conditions with no problems. The A-T3s are also very quiet tires on blacktop over 55 mph where normally such larger tires howl like jet engines. I highly recommend the A-T3 and will buy them again/suggest to friends.
