My Buying Guides on Gladiator X Comp 35X12.50R20
When I decided to upgrade my vehicle’s tires, I came across the Gladiator X Comp 35X12.50R20. After researching and testing, here’s what I learned and what I think you should consider before buying these tires.
Understanding the Size: 35X12.50R20
The size 35X12.50R20 tells you a lot about the tire. The “35” means the tire is 35 inches in diameter, which gives me a taller profile perfect for off-road clearance. The “12.50” refers to the width in inches, so these are quite wide tires that provide better traction and stability. Finally, “R20” means the tire fits 20-inch rims, which are common on trucks and SUVs. Make sure your vehicle can accommodate this size or you might run into fitment issues.
Performance and Traction
From my experience, the Gladiator X Comp tires excel in off-road conditions thanks to their aggressive tread pattern. They grip well on mud, rocks, and loose gravel, which makes them ideal for off-roading adventures. On the highway, they’re reasonably quiet, though not as smooth as all-season tires. If you spend a lot of time off-road but still want decent on-road manners, these strike a good balance.
Durability and Construction
One thing I appreciate about the Gladiator X Comp is their robust construction. They have reinforced sidewalls that resist punctures and cuts, which is crucial when driving on rough terrain. Over the months I’ve used them, they’ve held up well without noticeable wear or damage. If you’re tough on your tires, these might be a reliable choice.
Load and Speed Ratings
Before buying, I checked the load index and speed rating to ensure they meet my vehicle’s requirements. These tires typically support heavy loads suitable for trucks and SUVs, and their speed rating matches my usual driving speeds. Always verify these specs against your vehicle’s manufacturer recommendations.
Price and Value
The Gladiator X Comp tires are reasonably priced compared to other tires in the same category. While they aren’t the cheapest option, the durability and performance you get make them worth the investment in my opinion. I recommend comparing prices across retailers and looking for deals to get the best value.
Fitment and Installation Tips
Since these tires are large and wide, I made sure my truck’s suspension and wheel wells could handle them without rubbing. Sometimes a lift or leveling kit is necessary. Also, balancing and alignment after installation are important to avoid uneven wear and vibration. Consult a professional installer if you’re unsure.
Final Thoughts
Overall, the Gladiator X Comp 35X12.50R20 tires have been a solid upgrade for my vehicle. They offer great off-road capability without sacrificing too much on-road comfort. If you’re looking for aggressive, durable tires for your truck or SUV and are okay with a slightly rougher highway ride, these are worth considering. Just be sure to check fitment and specs for your specific vehicle before purchasing.
