The SST Pro and Maxx are two of Cooper’s best-performing all-season all-terrain tires. But it’s crucial to remember that they all excel in various ways.
Cooper’s ST Maxx is more appropriate for the more light off-roading activities. It makes no compromises while traveling and still has the grit and stamina to go camping in the mountains.
Conversely, the STT Pro is considered to be Cooper’s most innovative AT tire. It offers the dark roads nothing, just like its counterpart. Choose the STT Pro if you want something that will handle challenging off-road activities.

1. Off-Road Traction
Mud
AST Maxx is an adequate all-terrain tire that can handle practically any surface it comes across. Mud falls under this. However, the tire excels more in loose materials like gravel and dirt.
On the other hand, the STT Pro is particularly well adapted to thick, viscous terrain like deep mud.
Winner
STT Pro is the winner in deep, wet mud. You can count on it to rescue you from a sticky situation and maintain good traction.
2.Sand
ST Maxx is created to offer the best traction on sand. The tire is also suitable in places with high levels of heat.
On the other hand, the STT Pro can be counted on to manage the dunes despite being heavier and designed for larger cars; nevertheless, that is not where its expertise lies.
Winner
The ST Maxx, which made its debut on the sand, continues to dazzle as a tire that rules the powder.
3.Rock
The ST Maxx features stone ejector tread tech, which increases its resilience against rock shrapnel and harsh, uneven conditions. Nobody has any complaints about traction or performance.
The STT Pro, on the other hand, has deep treads and rock climber sidewall technology that provide you the traction you need to manage rocks of various sizes.
Winner
The STT Pro is the category winner since it is designed explicitly for rocks.
On-Road Characteristics
- noise.
The ST Maxx can tolerate noise levels on the road comparable to HT tire levels thanks to its hard compound material, robust sidewalls, and considerably shallower treads.
The STT Pro, on the other hand, has deep treads and softer materials that make them ideal for tough mud. The STT Pro is a noisy tire as a result.
Winner
As you can see, the ST Maxx is relatively quiet for an all-terrain tire. Superior to the STT Pro.
- Ride Quality
The ST Maxx tire from Cooper handles well. It will inevitably lose some of its handling and gain more positive steering as it accelerates to higher speeds.
Cooper’s STT Pro, on the other hand, experiences significant handling losses at higher speeds due to its enormous weight than the ST Maxx.
Winner
Driving on the ST Maxx is slightly more pleasant than the STT Pro.
Wet Performance
ST Maxx maintains excellent wet performance thanks to a rubber compound strengthened by silica. To minimize loss of grip, it rapidly dewaters as it rotates.
The STT Pro, on the other hand, has directional tread like many other tires, which is intended to offer the most excellent traction possible in wet conditions.
Winner
While both tires perform admirably on wet surfaces, the ST Maxx has somewhat superior handling.

Winter Performance
Powder and loose stuff are where the ST Maxx shines. The ST Maxx continues to excel as a winter tire in light or powdery snow. On ice, it will keep a decent grip as well.
On the other hand, the STT Pro excels in deep mud and firm terrain. The Cooper STT Pro performs better on packed snow than on powder when it comes to snow. The ST Pro has no notable advantages or disadvantages on the ice, much as the ST Maxx.
Winner
Generally, both tires will offer you exceptional performance in the winter.
Tire Inflation
There are 47 distinct sizes of the ST Maxx available, with tire pressures ranging from 35 to 80 psi.
On the other hand, the STT Pro is available in 48 different sizes and has tire pressures ranging from 35 to 80 psi.
Winner
There is no winner in this division because both tires can withstand the same range of pressures.
Fuel economy
ST Maxx tires will let you travel two to three miles per gallon of fuel. On the hand, SST Pro will knock off 1.5 miles per gallon
Winner
When talking about fuel economy, the ST Max tire carries the day.
