When I decided to upgrade my vehicle’s tires, I focused on the Gladiator Xcomp Mt 35X12.50R20 tires because they promised durability and performance for off-road adventures. Here’s what I learned during my buying journey that might help you make an informed decision.
Understanding the Size: 35X12.50R20
The size 35X12.50R20 means the tire has a 35-inch overall diameter, 12.5-inch width, and fits a 20-inch rim. For me, this size was perfect to enhance ground clearance and provide a more aggressive stance for my truck. Make sure your vehicle can accommodate this size without modifications or check if you need a lift kit.
Tread Design and Performance
The Gladiator Xcomp Mt features a mud-terrain tread pattern, which was ideal for my off-road needs. The deep, aggressive lugs helped me tackle muddy trails, rocky paths, and loose dirt with confidence. I noticed excellent traction in challenging conditions, but keep in mind this type of tread might be noisier on highways.

On-Road Comfort and Handling
While these tires are primarily designed for off-road, I was curious about their on-road behavior. They provided a stable and controlled ride at highway speeds, although the tread noise was noticeable compared to all-terrain tires. If you mostly drive on pavement, consider how much noise you’re willing to accept.
