The Cooper Discoverer Rugged Trek All-Season 37X12.50R20LT 126Q Tire is an all-season pickup truck and SUV tire that looks tough because it is tough. It looks aggressive but it also has nice manners. The Rugged Trek has a unique Rough Terrain pattern, which is trail capable and provides extra grip and confidence when you venture off the highway. It also features Stone Blockades, which are ridges in the tire pattern to help keep pesky stones and rocks out of the tire and on the ground where they belong, helping protect the tire from damage when you're off the beaten path. Rugged Trek is built to provide enhanced grip on wet roads and features Whisper Grooves Technology that blocks the rush of air through the tire, helping to eliminate noise when on the highway. There are dual sidewall designs so you can pick between the Mountain Pass pattern or Knife-Edge pattern, which gives you double the options for your look. Our aggressive tread blocks are designed for quiet on-road performance and deep treads help grip in sticky mud and sand. While this is a tough-looking tire, it is also engineered for a quiet and comfortable drive.
