Gladiator X Comp M/T Review: I Tested This Budget Mud Tire Hard

If you’ve been shopping for mud terrain tires lately, you already know the sticker shock is real. Big-name brands like BFGoodrich and Nitto will run you well over $300 per tire in most popular sizes, and that’s before mounting and balancing.

So when Gladiator — a brand that flies under the radar for a lot of drivers — offers a mud terrain tire at nearly half the price, it’s natural to wonder: is it actually any good, or are you just throwing money away?

I spent an extended period testing the Gladiator X Comp M/T on a 2019 RAM 1500 across a variety of conditions — highway cruising, rain-soaked backroads, rocky trails, and genuine mud pits — to find out exactly where this tire delivers and where it falls short. Here’s my complete, unfiltered review.

Who Makes the Gladiator X Comp M/T?

Before I get into performance, let’s address the elephant in the room: most people have never heard of Gladiator Tires. That’s fair. They’re not sitting next to Goodyear and Michelin at your local Discount Tire.

Gladiator is a brand under the Trailer King / Greenball umbrella, which is a US-based tire distributor headquartered in New Jersey. They’ve been in the tire business for decades, primarily known for trailer tires and budget off-road options. The X Comp M/T is their flagship mud terrain offering and represents their push into the more serious off-road market.

I’ll be honest — I was skeptical going in. Budget tire brands have burned me before, and I wasn’t sure what to expect from a company better known for trailer tires. But I believe in judging a tire by its performance, not its marketing budget, so I approached this test with an open mind.

First Impressions and Build Quality

The Gladiator X Comp M/T arrived and immediately looked the part. The tread design is aggressive — deep, wide voids between chunky tread blocks with stone ejector ribs running through the grooves. The sidewall features a prominent, raised design that’s both functional (added sidewall protection) and aesthetic.

I ran the 35×12.50R20 size on my RAM 1500, and the tire had a satisfying heft to it. The rubber compound felt firm but not overly stiff, which I took as a good sign for a balance between off-road durability and on-road comfort.

One thing I noticed right away: the bead area looked clean and well-constructed. I’ve seen budget tires with sloppy bead construction that leads to slow leaks and mounting headaches. The X Comp M/T didn’t give my local shop any trouble during installation, and I had zero bead-related issues throughout my entire test period.

The 3-ply sidewall construction (in LT sizes) gives it a solid feel without being excessively heavy. For comparison, some premium mud terrains in this size push 70+ pounds per tire. The Gladiator comes in slightly lighter, which I appreciated for daily driving fuel economy.

On-Road Performance: The Daily Drive Test

Let’s be real — most people buying mud terrain tires still spend 80% or more of their time on pavement. So on-road performance matters, even if it’s not the primary selling point. I commuted with these tires, ran errands, and took several highway trips during my testing period.

Highway Comfort and Noise

This is where every mud terrain tire faces its biggest challenge, and the Gladiator X Comp M/T is no exception. It’s loud. Not “screaming at you” loud, but definitely a noticeable hum that becomes your constant companion at highway speeds.

At around 40–50 mph, there’s a distinct drone that settles in. By 65–70 mph on the interstate, it’s a consistent low-frequency hum that I’d describe as moderate. I could still carry a conversation without raising my voice, and my truck’s audio system easily drowned it out. But if you’re coming from a set of all-terrain tires or highway tires, the difference is immediately obvious.

For context, I’ve driven on BFGoodrich KM3s and Toyo Open Country M/Ts, and the Gladiator sits roughly in the same noise ballpark as the Toyo — maybe a touch louder. The BFG KM3 is noticeably quieter on-road, but it also costs significantly more.

Ride comfort on smooth pavement was surprisingly decent. The tires absorbed small imperfections without transmitting harsh vibrations into the cabin. On rougher highways — the kind of crumbling asphalt you find all over the Midwest and South — I did feel more feedback through the steering wheel than I would with an all-terrain tire.

Dry Pavement Handling

On dry roads, the Gladiator X Comp M/T performed about as well as I’d expect from any mud terrain tire. Braking distances felt normal, and the truck tracked straight at highway speeds without any wandering.

Cornering grip on dry pavement was adequate. These aren’t performance tires, and you’ll feel the tread blocks flex if you push it through a tight turn. But for normal driving — lane changes, highway ramps, parking lot maneuvers — they felt stable and predictable.

I did notice a slight looseness in the steering feel compared to the all-terrain tires I had on previously. This is typical of mud terrains due to the wider tread voids and more flexible tread blocks. It’s nothing dangerous, just something to be aware of if you’re transitioning from a less aggressive tire.

Wet Road Performance

Here’s where I have mixed feelings. In light to moderate rain, the X Comp M/T performed fine. Water evacuation seemed adequate at normal speeds, and I didn’t experience any unexpected sliding or loss of traction during my daily driving in wet conditions.

However, during a particularly heavy downpour on I-65, I felt the rear end get a little light at highway speeds. It wasn’t a full hydroplane event, but there was a noticeable reduction in confidence compared to all-terrain tires I’ve run in similar conditions. I slowed down and everything was fine.

This isn’t unique to the Gladiator — it’s a characteristic of mud terrain tires in general. The wide tread voids that make them excellent in mud can work against them on wet pavement at speed. Just something to keep in mind if you live in a region with frequent heavy rain.

Off-Road Performance: Where This Tire Earns Its Keep

Alright, this is what you really want to know about. I took the Gladiator X Comp M/T through a variety of off-road conditions over my testing period, and this is genuinely where the tire impressed me most.

Mud Performance

It’s right there in the name — M/T, mud terrain — so it better perform in the slop. And it does. Impressively.

I hit several muddy trails in southern Indiana after heavy rains, including some genuinely thick, clay-based mud that has swallowed tires whole. The X Comp M/T dug in, cleared mud from the tread voids effectively, and maintained forward momentum where I expected to get stuck.

The wide spacing between the tread blocks is the star of the show here. Mud clears quickly, and the aggressive shoulder lugs bite into the edges of ruts to help pull you through. I was running about 18 PSI during these mud runs (aired down from my usual 35 PSI highway pressure), and the tire’s footprint spread nicely for maximum traction.

I’ll say this: in pure mud performance, the Gladiator X Comp M/T held its own against mud terrains costing twice as much. I’ve had similar experiences on BFGoodrich KM3s in comparable conditions, and I’d rate them roughly equal in moderate mud. In extreme, deep mud bog situations, the BFG might edge it out due to its slightly more advanced tread compound, but for 90% of real-world mud situations, the Gladiator gets the job done.

Rock and Gravel Performance

On loose gravel roads and rocky trails, the X Comp M/T performed well. The stone ejector ribs in the tread grooves did their job — I pulled very few rocks from the tread after my trail sessions, which is a good sign for long-term puncture resistance.

Crawling over larger rocks at low speed, the 3-ply sidewall gave me enough confidence that I wasn’t going to gash a sidewall on a sharp edge. I wouldn’t compare it to a premium tire with reinforced sidewall armor, but for the price, the protection level felt appropriate.

Traction on steep, rocky inclines was solid. The tread blocks gripped individual rocks well, and the tire didn’t feel like it was skating across surfaces. I climbed a few moderately challenging rock sections without needing to air down below 20 PSI.

Sand Performance

I took a trip to the dunes in Michigan and ran the X Comp M/T in soft sand, aired down to about 15 PSI. The tire floated on top of the sand reasonably well once aired down, though it doesn’t match dedicated sand-oriented designs.

The aggressive tread pattern can dig in if you’re not careful with throttle input in deep sand. This is a characteristic of all aggressive mud terrain tires — the same lugs that claw through mud want to dig trenches in sand. Smooth throttle application and lower air pressure are your friends here.

Overall, sand performance was acceptable. Not exceptional, not terrible. If you’re primarily a beach/dune driver, there are better options. But for the occasional sand encounter, the X Comp M/T won’t leave you stranded.

Snow and Light Winter Use

I want to be clear: this is not a dedicated winter tire, and it does not carry the Three-Peak Mountain Snowflake (3PMSF) symbol. With that caveat, I did drive on it during a late-season snow event and can share my observations.

In a few inches of fresh, unpacked snow, the tire actually performed surprisingly well. The aggressive tread pattern bit into the snow and provided decent forward traction. It felt significantly better than a highway tire would in the same conditions.

On packed snow and ice, however, it was a different story. Traction was limited, and I had to be very deliberate with my inputs. The rubber compound isn’t formulated for cold temperatures, so it stiffens up and loses grip on hard, slick surfaces.

If you live in the Snow Belt and need genuine winter capability, I’d recommend a dedicated winter tire set or at least an all-terrain with the 3PMSF rating. The X Comp M/T is a fair-weather off-road tire that can handle an occasional snow surprise, but it shouldn’t be your planned winter solution.

Tread Life and Durability

Mud terrain tires are notorious for wearing faster than all-terrain or highway tires, so tread life is always a concern. During my extended test period, the Gladiator X Comp M/T showed encouraging signs.

After several weeks of mixed driving — highway commuting, back roads, and multiple off-road outings — the tread blocks showed minimal visible wear. The edges of the tread blocks stayed relatively sharp, and I didn’t see any signs of chunking or tearing, even after some aggressive rock crawling.

The tire doesn’t come with a treadwear warranty, which is typical for mud terrain tires in this price range (and even many premium ones). But based on my observations, the tread compound seems durable enough to deliver a reasonable service life if you rotate regularly and maintain proper inflation.

I’ll note that I rotated these tires after the first few weeks and plan to continue on a regular rotation schedule. Uneven wear is the enemy of any aggressive tire, and consistent rotation is your best defense.

How Does the Gladiator X Comp M/T Compare?

I think comparison is the most useful tool when evaluating a budget tire. Here’s how the Gladiator X Comp M/T stacks up against some popular competitors I’ve tested or have extensive experience with:

Gladiator X Comp M/T vs. BFGoodrich KM3

The KM3 is the gold standard in mud terrain tires, and the Gladiator can’t match it in every category. The BFG has a more refined on-road personality, better wet traction, and superior sidewall technology with its Krawl-TEK compound.

But here’s the thing — the KM3 costs nearly double. In terms of performance per dollar, the Gladiator X Comp M/T is the clear winner. If you’re on a budget and need serious mud capability, the Gladiator gets you about 85% of the KM3’s off-road performance at roughly 55% of the price. That math is hard to argue with.

Gladiator X Comp M/T vs. Federal Couragia M/T

The Federal Couragia M/T is probably the most direct competitor in terms of price. I’ve run Couragias in the past and found the Gladiator to be a step up in nearly every category. The X Comp M/T has better mud clearing, more refined on-road manners, and appears to be wearing more evenly. If you’re cross-shopping these two, I’d go Gladiator without hesitation.

Gladiator X Comp M/T vs. Nitto Trail Grappler

The Trail Grappler is a “hybrid” mud terrain that leans more toward on-road refinement. It’s quieter and more comfortable on the highway, but it doesn’t match the Gladiator’s pure mud performance. If you spend more time on-road, the Nitto is worth the premium. If you prioritize off-road capability on a budget, the Gladiator is the smarter buy.

Available Sizes and Pricing

The Gladiator X Comp M/T comes in a solid range of sizes that cover most popular truck and SUV applications:

• 15-inch: Starting from around $130 per tire
• 16-inch: Approximately $140–$170 per tire
• 17-inch: Approximately $150–$200 per tire
• 18-inch: Approximately $170–$220 per tire
• 20-inch: Approximately $180–$250 per tire
• 22-inch: Approximately $220–$280 per tire
• 24-inch and 26-inch: Available for lifted truck setups, pricing varies

One thing I appreciate about the X Comp M/T lineup is the availability of larger, more aggressive sizes (like 37s and 40s) that many budget brands don’t offer. If you’re running a lifted truck with oversized wheels, Gladiator has you covered.

Pricing is typically best through online retailers like Simple Tire, Tire Rack, or Priority Tire. I’ve also seen them available at some Discount Tire locations, though availability varies by region. It’s always worth calling your local installer to check if they can source them and what the mounted-and-balanced total would be.

Who Should Buy the Gladiator X Comp M/T?

After spending extensive time on these tires, I have a pretty clear picture of who they’re ideal for — and who should look elsewhere.

The Gladiator X Comp M/T Is Perfect For:

• Budget-conscious off-roaders: If you want genuine mud terrain performance without spending $1,400+ on a set of premium tires, this is one of the best values on the market right now.
• Weekend warriors: If you daily-drive your truck but hit trails on weekends, the X Comp M/T offers a good balance. You’ll deal with some highway noise, but the off-road payoff is worth it.
• Truck builders on a budget: If you just lifted your truck and spent your tire budget on suspension, these tires look great, perform well, and won’t break the bank.
• Hunters and outdoor enthusiasts: If you need to reach remote hunting spots or campsites via muddy, unimproved roads, these tires will get you there reliably.

You Might Want to Look Elsewhere If:

• Highway comfort is your top priority: If you do 90% highway driving and rarely go off-road, an all-terrain tire (like the Falken Wildpeak AT3W or Cooper Discoverer AT3 4S) will be a much better daily driver.
• You need serious winter capability: Without the 3PMSF rating and a cold-weather compound, these aren’t the tires for a Minnesota winter commute.
• You’re an extreme rock crawler: For dedicated rock crawling, the BFGoodrich KM3 or a specialty tire like the Maxxis Trepador is worth the investment for the enhanced sidewall protection and grip.
• You demand whisper-quiet highway driving: No mud terrain tire is quiet, but if noise is a dealbreaker, this category isn’t for you.

Installation Tips and Maintenance

Based on my experience, here are some practical tips if you decide to go with the Gladiator X Comp M/T:

Balance carefully: Like most mud terrain tires, these can require a bit more weight to balance than a standard tire. I recommend asking your installer to use a road-force balancer if available — it made a noticeable difference in eliminating vibration at highway speeds.

Break them in: During the first few days of driving, I noticed the tires felt a little slippery on dry pavement. This is normal — new tires have a mold-release compound on the surface that wears off after some initial driving. Take it easy for the first couple of days.

Rotate religiously: I cannot stress this enough. Mud terrain tires with aggressive tread patterns are prone to uneven wear if you neglect rotations. I recommend every 5,000 to 6,000 miles, or simply make it a habit every time you change your oil.

Check pressures weekly: I found these tires held air well, but the wide tread voids mean they’re more susceptible to picking up debris that can cause slow leaks. A quick weekly check takes two minutes and can save you from a flat.

Air down for off-road: These tires really come alive at lower pressures off-road. I typically ran 18–20 PSI on trails and felt a dramatic improvement in traction compared to street pressures. Just make sure to air back up before hitting the highway.

The Aesthetics Factor

Let’s talk about looks, because I know that matters to a lot of truck owners. The Gladiator X Comp M/T is a genuinely aggressive-looking tire. The tread pattern is bold and mean, the sidewall design features a prominent raised pattern, and the white lettering (on the alternate sidewall) looks clean if you choose to run it outward.

On my black RAM 1500, these tires transformed the truck’s appearance. I received multiple compliments at gas stations and trail meetups, and most people were surprised when I told them the brand and price. They simply look more expensive than they are.

The “Gladiator” branding on the sidewall is tasteful and not overly large. It doesn’t scream “budget tire” the way some cheaper brands do. If aesthetics are part of your buying decision — and for many of us, they absolutely are — the X Comp M/T delivers.

Potential Drawbacks and Honest Criticisms

No tire is perfect, and I want to be transparent about the areas where the Gladiator X Comp M/T falls short:

Road noise is real: I’ve mentioned it multiple times, but it bears repeating. If you’re sensitive to cabin noise, this tire will bother you on long highway drives. It’s not the loudest mud terrain I’ve tested, but it’s noticeably louder than any all-terrain tire.

Wet handling could be better: The tire handles light rain fine, but heavy downpours at highway speed revealed its limitations. I’d like to see Gladiator develop a slightly more optimized siping pattern for improved wet grip in future iterations.

Limited brand reputation: This isn’t a performance issue, but it’s worth mentioning. If you ever sell your truck, a set of BFGoodrich tires adds more perceived value than Gladiator tires. It’s an unfair bias, but it exists.

No UTQG rating published: Unlike many mainstream tires, the Gladiator X Comp M/T doesn’t prominently publish its UTQG (Uniform Tire Quality Grading) numbers, which makes objective tread life comparisons with competitors more difficult.

Availability can be spotty: While online availability is generally good, finding these tires at a local brick-and-mortar shop can be hit or miss depending on where you live. This means you may need to order online and have them shipped to an installer, which adds a step to the buying process.

My Final Verdict on the Gladiator X Comp M/T

After spending extensive time with the Gladiator X Comp M/T across every type of terrain and condition I could throw at it, I’m genuinely impressed with what this tire offers for the money. Is it the best mud terrain tire you can buy? No. But it might be the best value in mud terrain tires on the market right now.

The off-road performance — particularly in mud and loose terrain — rivals tires costing $150–$200 more per tire. The on-road behavior is livable for a daily driver who understands and accepts the inherent trade-offs of running a mud terrain tire. And the build quality, in my experience, has shown no red flags.

I’d rate the Gladiator X Comp M/T a solid 4.2 out of 5 stars. It loses points for highway noise and wet-weather confidence, but it earns them back with outstanding value and genuinely capable off-road performance.

If you’re a truck or SUV owner who wants to run a real mud terrain tire without emptying your bank account, the Gladiator X Comp M/T deserves serious consideration. It’s one of those rare budget products that actually delivers on its promises.
