My Buying Guides on Gladiator Xcomp Mt 35X12 50R20 Tires
When I was searching for the perfect tires for my truck, the Gladiator Xcomp Mt 35X12 50R20 caught my attention. Here’s what I learned and what helped me decide that these tires were right for me.
Understanding the Size: 35X12.50R20

I found the deep tread patterns and reinforced sidewalls gave me great traction and durability when I took my truck off the beaten path.
On-Road Comfort and Noise
Since I also use my truck daily on highways, I was concerned about road noise and ride comfort. These tires are a bit louder than all-terrain tires due to their aggressive tread, but I found the noise level manageable and the ride stable. If you prioritize a quiet ride over off-road capability, keep that in mind.
Durability and Build Quality
Durability was a big factor for me. The Gladiator Xcomp Mt tires have strong sidewalls and a tough rubber compound, which helps resist punctures and cuts. After some rough trails, my tires showed minimal wear, which reassured me that they can handle tough conditions over time.
Price and Value
These tires are competitively priced for their category. I compared them with other mud-terrain options and felt that the Gladiator Xcomp Mt offered a great balance between performance and cost. Keep in mind that investing in quality tires can save money in the long run by reducing replacement frequency.
Installation and Maintenance Tips
When I got my Gladiator Xcomp Mt tires, I had them professionally installed and balanced. Regular rotations every 5,000 to 7,000 miles helped me maintain even tread wear. Also, checking tire pressure frequently is important to maximize performance and tire life.
Final Thoughts
If you’re looking for aggressive off-road tires that still perform reasonably well on-road, the Gladiator Xcomp Mt 35X12 50R20 is a solid choice. Just make sure your vehicle can accommodate the size, and be prepared for a bit more road noise. Overall, these tires gave me confidence both on rugged trails and everyday driving.
