This listing is for new Cooper Discoverer Rugged Trek 37X12.50R20 E/10PLY Tires. Manufacturer part number: 170214007. The Cooper Discoverer Rugged Trek is an all season truck and SUV tire for off road explorers who also want a tire with excellent on road manners too. With its aggressive, deep tread pattern to handle the off road conditions easily, the Rugged Trek is built for long milage and comfort on road trips. It comes equipped with Cooper Whisper Grooves to reduce high speed noise that is common in more aggressive truck tires. It has excellent grip and the Stable Trac Technology optimizes stability and control, while the omni-directional sipes further promote traction on roads and varied off road surfaces. The alternating angle tread blocks have biting edges for enhanced grip and wide grooves to quickly evacuate water, slush or loose materials. Customize your sidewall by picking from one of the two different patterns on the tire. Both patterns have long, deep clears for off road traction and bold black, raised lettering. The Discoverer Rugged Trek has it all, aggressive traction and stability while still providing smooth, quiet on road manners.
