I needed a tire that could handle rough terrains—mud, rocks, and sand—without compromising durability or traction. This tire’s aggressive tread design gave me the confidence to tackle challenging trails that other tires simply couldn’t manage.
Another reason I found this tire necessary is its incredible toughness. I’ve taken it through harsh conditions, and it hasn’t shown signs of premature wear or damage.

My Buying Guides on Cooper Stt Pro 35X12 50R20
When I was searching for the perfect tire upgrade, the Cooper STT Pro 35X12.50R20 caught my eye for its rugged design and impressive off-road capabilities. Here’s what I learned and considered during my buying journey to help you make a confident choice.
Understanding the Tire Size: 35X12.50R20
First off, it’s important to decode the tire size. The “35” represents the overall diameter in inches, which means these tires are quite large and great for off-road clearance. The “12.50” is the tire width in inches, offering a wider footprint for better traction. Finally, “R20” indicates that the tires fit 20-inch wheels, which are common on many trucks and SUVs. I made sure my vehicle could accommodate this size without major modifications.
Why I Chose Cooper STT Pro
Cooper’s STT Pro tires have a strong reputation for durability and performance in tough terrains. I was drawn to the aggressive tread pattern designed to bite through mud, rocks, and loose surfaces. The reinforced sidewalls gave me confidence that these tires could handle rough trails without getting damaged easily.
Performance on and off the Road
One of my main priorities was having a tire that performs well both on highways and off-road. The Cooper STT Pro 35X12.50R20 offers a solid balance: on-road driving feels stable and quiet for such an aggressive tread, while off-road traction is exceptional. I noticed improved grip in mud and snow compared to my previous tires.
Durability and Longevity
I looked into the tire’s construction and user reviews to gauge durability. The STT Pro features a tough compound and sidewall armor that resists cuts and punctures. This meant fewer worries about tire damage during my off-road adventures. Plus, the tread life is commendable, offering good mileage before replacement.
Considerations Before Buying
- Vehicle Compatibility: Ensure your truck or SUV can fit 35-inch tires without rubbing or requiring suspension lifts.
- Fuel Economy: Larger, wider tires can slightly reduce fuel efficiency due to increased rolling resistance.
- Ride Comfort: Aggressive tread patterns may cause a bit more road noise compared to highway tires. I found this acceptable given the off-road benefits.
- Budget: These tires are a worthwhile investment, but prices can be higher than standard all-terrain tires.
My Final Thoughts
The Cooper STT Pro 35X12.50R20 is an excellent choice if you want a durable, high-performance tire for serious off-roading without sacrificing too much on-road comfort. After fitting these on my truck, I’ve felt more confident tackling challenging trails and adverse weather. Just be sure to verify fitment and consider your driving needs before making the purchase.
