TIRETEST By Bruce W. Smith COOPER STT A high-traction mud tire designed for those jobsites where traction and tough sidewalls take precedence T here are literally dozens of mud tires on the market from smaller regional brands to internationally known name brands. Among the latter is Cooper Tire, one of the top 12 tire manufacturers in the world. Cooper's Discoverer STT is their premium off-road light truck 24 PROPICKUP December 2013 traction tire – a tire that has been a proven performer from the deserts of Dakar to the muddy logging roads of Maine. If you are a fleet manager or contractor looking for a premium-grade mud tire to run on your pickups during the mud season in your area, the Cooper STT would be a good choice. The Cooper SST looks good under a pickup and delivers when it comes to off-pavement traction. The lugs are both open and deep, allowing them to dig down for traction while the large voids help them clean under acceleration. I saw this time and again when the LT285R17 Cooper STTs under my 2011 GMC Sierra 1500 4x4 rolled through the red clay of construction sites and other off-pavement conditions on the Mississippi Gulf Coast. The tire's carcass is made from Armor-Tek3, which combines the typical 2-ply sidewall construction with a third ply at an eightdegree angle over the others.
