Now, let us go over its performance rating under various aspects. These performance ratings can be conducted by several auto tire dealers and car shops. This information will give you a better understanding of its abilities and limitations.

Off-Road Performance

The overall off-road performance of this tire is around 98 percent efficiency which is strongly linked to its features and tread compound. First, its staggered alternate tread ribs contribute greatly to its stability, handling, traction on deep mud and harsh off-road surface. Its enlarged depth side tread blocks add more biting grip for muddy conditions and inclined surfaces to avoid slippage. It also has stone tread ejectors which push sharp protruding rocks on the way. Moreover, its flex groove feature helps promote a smooth ride on uneven surfaces.

Dry Traction

Dry traction performance covers dry traction, cornering, handling, and responsive steering. Under this category, this tire exhibited around 90 percent efficiency. This is attributed to the staggering alternate tread ribs which improve stability and handling abilities. Its wider shoulder block and reinforced sidewall promote effective cornering skills. Likewise, these tread designs also promote a good braking system.

Wet Traction

The wet traction performance covers hydroplaning resistance and wet traction abilities. For this tire, it showed around 90 percent efficient overall wet traction rating. The deep voids and micro-siping tread patterns contribute much to its excellent performance. It enables a quick redirection of water particles from the tire surface so that there will still be enough contact between the tire and the road surface. The micro-sipings and silica compound improves hydroplaning resistance to prevent slippage.

Snow Traction

Surprisingly, this tire can do well on light to deep snow conditions. The rugged tread patterns and silica compound of this tire provide sufficient biting edge and grip on snow surfaces.

Noise Level and Comfort

Most people have prejudices about off-road tires as being too noisy on on-road surfaces. For this one, its staggered alternate inner tread ribs provide decent noise reduction and great handling and stability for highway driving. Likewise, its flex groove feature provides a smooth ride on uneven surfaces.

Tread Life

This tire has the new tread compound Armor Tek3 Carcass construction. It is a patented technology by Cooper Tires which uses 3-ply construction in its main tread and sidewall blocks. This feature gives a longer tread life for the tire in extreme off-road surfaces and 50 percent increased protection against chips and cuts.
