While this aspect might not sit well with some eco-conscious drivers, it’s essential to remember that the Discoverer STT Pro is purpose-built for off-road adventures, where fuel efficiency often takes a back seat to capability.
Tread Wear
Another consideration with mud-terrain tires is tread wear. Due to the aggressive tread design, these tires are prone to more rapid wear, especially when driven extensively on pavement. While Cooper has incorporated Armor Tek3® Technology to enhance sidewall strength and durability, the tread blocks are still exposed to significant wear from asphalt and concrete surfaces. Frequent rotations and proper tire maintenance can help prolong the life of the Discoverer STT Pro, but it’s crucial to be aware of the balance between off-road prowess and tread longevity.
Despite the relatively higher rolling resistance and accelerated tread wear, the Discoverer STT Pro is a tire designed for those who prioritize off-road performance above all else. The increased fuel consumption and tread wear are trade-offs that many enthusiasts willingly accept to experience the tire’s outstanding capabilities in challenging terrains.
Warranty
When it comes to warranty coverage, Cooper offers the Discoverer STT Pro with a Standard Limited Warranty. This warranty provides protection against manufacturing defects and workmanship issues for a specified period from the date of purchase. However, it’s essential to note that the Discoverer STT Pro does not come with a Treadwear Protection Warranty, which is quite common for most off-road and mud-terrain tires. The absence of a Treadwear Protection Warranty means that Cooper does not guarantee a specific mileage range for the tire’s tread life, as it can vary significantly based on driving habits, road conditions, and the intensity of off-road usage.
While the lack of a Treadwear Protection Warranty might seem like a drawback, it’s essential to understand that mud-terrain tires are designed for specialized off-road performance, and their tread life is often prioritized differently from standard highway tires. Off-road enthusiasts typically prioritize grip and performance over extended tread life, making treadwear warranties less critical in their decision-making process.
