Review summary

AI-generated from verified customer reviews.
The Cooper Discoverer STT Pro tires receive generally positive reviews for their performance and appearance, with some mixed feedback on specific aspects.
The Cooper Discoverer STT Pro tires are generally well-regarded for their off-road capabilities and aggressive styling. They perform well in various terrains, including mud, rocks, and wet conditions. Many users appreciate the relatively low road noise for a mud terrain tire, though some report increased noise over time. While most reviewers are satisfied with tread life, there are a few instances of premature wear. The tires' performance in snow and ice is mixed, and some users note a decrease in fuel efficiency. Despite these drawbacks, many customers find the Cooper Discoverer STT Pro to be a good balance of off-road performance and on-road manners for their needs.

Cooper STT Pro

Best all around mud/snow tire in my opinion. I run them year round on pavement, mud, rocks, dirt roads, and of course in the winter. They do great in all conditions and especially ice which is not common for a mud type tire. They do wear out quickly. I get around 18-20k on them. They are on a 2017 f250 with a gas motor and this is my 5th set on it.

Be careful with simple tire

So I ordered the coopers recently as I have always had pretty good experiences with them. I recently had a blowout so had to go ahead and put these tires on. The tire shop pointed out some damage to a sidewall but I had no other choice but to install them. I have about 100 miles on them now with no problems but not to say I won't have problems. Plus for the cost of these in a 35x12.50R20 is outrageous for what I recieved. So far so good but hope it doesn't cause a blowout. Simple tire is no help either nor do they care about their customers. Your just a number to them

Didn't last 9 months

Bought these in Feb 2023 and its now Nov 2023 and I have to replace them. Took a 5k mile road trip from MS to UT/CO and that trip destroyed these tires. 5k miles of pavement should not have worn them down so quick to the point of where they are at past the treadwear markings. I've put maybe 10k miles on them total. I've had cheap tires last longer than these and these were almost $400 a piece.

Get technical:

The Cooper Discoverer STT Pro is a mud-terrain tire that's designed for use on Jeeps, SUVs, and light trucks, and offers drivers increased durability, strong on- and off-road traction, and protection from debris and sharp rocks.



Features & Benefits

  • Mud-terrain tread
  • Raised White Letter or Black sidewall depending on the tire's size
  • Backed by Cooper's 45-Day Satisfaction Guarantee and Limited Warranty (restrictions and limitations apply)
  • Robust lugs and deep biters are responsible for great traction over muddy, sandy, and rocky surfaces as they work with Earth Diggers Technology to dig deep into dirt and mud

Not all drivers of vehicles with mud-terrain tires consider only off-road traction. Some drivers look for balanced tires that are also good on pavements and ensure a balanced performance both on- and off-road. Fortunately, the Cooper Discoverer STT Pro is designed for good on- and off-road traction, featuring a unique rubber compound and 3 prominent ribs of equal sizes. All 3 ribs of this mud-terrain tire feature ingroove notches, offset sides, and sawtooth edges for enhanced gripping ability in challenging conditions. The Rock Climber Sidewall Technology allows the tire to conquer difficult obstacles, while the Stone Armor Technology ensures protection from sharp rocks and debris. The Discoverer STT Pro is highly durable, featuring the Armor Tek3 Technology. Some of its compatible vehicles include the Chevrolet Silverado 1500, Toyota Tundra, Jeep Wrangler, and more.
