Our Project Venture Toy was built to be a versatile truck capable of long-distance highway travel, backcountry camping trips, and wheeling sand to rocks. As such, we need a good all-around tire capable of meeting this wide range of applications. Granted, no tire will excel in all terrain, but a lot of 'wheelers have similar diverse needs and hope to do well overall with a single tire choice. We recently acquired a set of 37-inch Cooper Discoverer STT tires to mount on our Tacoma.
The Discoverer STT is Cooper's most aggressive light truck tire. The STT stands for Super Traction Tire. It offers a high-void tread area with wide spacing between tread lugs, and has scalloped shoulder lugs for further sidewall traction. Their Armor-Tek3 carcass consists of two radial polyester body plies and one angled polyester body ply to provide three full plies of protection. It's also a visually appealing tire.
We mounted a 37-inch set on our 17x9 OMF bead-locked wheels reusing our ceramic Dyna Beads for balancing. We found the overall height to be very close to a full 37 inches and the weight of the tires to be about 82 pounds each.
On the highway, the tires were well behaved. They tracked well with no hint of wander or hop. We were met with the usual hum associated with running a mud tire, but it was pleasantly quiet, and without any resonant drone. We tried the tires in dry dirt, snow, mud, and on rock. We found little to complain about, and were very pleased with the overall performance of the Discoverer STTs.
We think it's fair to say these tires are a great choice for someone looking for an aggressive radial tire that can comfortably handle the street and get you where you want to go off the street. The Super Traction Tire does the job well when it comes to tackling a variety of traction scenarios.
