The Best 37X12.50R20 All Terrain Tires, Reviewed
Kenda Klever R/T KR601
Strengths
- Three-Peak rated
- Excellent snow grip
- Reinforced bead
Trade-offs
- Premium price point
- Heavier rotation
- Slight road noise
The Kenda Klever R/T KR601 is the most complete package in this lineup, and that’s why it earns my pick for best overall. It combines a three-ply carcass, high sipe density, and Three-Peak certification into a tire that performs well across every category, snow, mud, rock, and highway. The interlocking center blocks deliver consistent grip, and the bead protector helps when airing down on sharp trails.
Compared to the Falken A/T4W, it’s more aggressive off-road and slightly more durable, though not quite as refined at 80 mph on smooth asphalt. But for those who want one tire to handle everything from winter commutes to desert overlanding, the Klever R/T strikes the best balance. It’s not the cheapest, but it’s the one I’d spec on my own rig if I wanted to go four seasons and beyond without compromise.

Sailun Terramax R/T
Strengths
- Three-Peak certified
- Budget pricing
- Stud-capable
Trade-offs
- Firmer ride quality
- Average tread life claims
- Less aggressive off-road
At this price, the Sailun Terramax R/T punches above its weight. The Three-Peak Mountain Snowflake rating is a standout, few budget R/T tires offer certified winter performance, and owners confirm it handles snowy mountain passes with confidence. The deep tread depth means it’ll last longer than most in its class, especially if you rotate it regularly.
It’s not flawless. Ride comfort lags behind the Terra Commander, and the sidewall isn’t as fortified as the Gladiator’s. But when you factor in the stud-pin capability and all-weather legitimacy, it becomes the smart buy for budget-conscious buyers who still want real versatility. I’d choose this over pricier R/Ts if I lived in a region with harsh winters and didn’t want to swap tires seasonally.

Falken Wildpeak A/T4W
Strengths
- Three-Peak rated
- Excellent wet grip
- Long tread life
Trade-offs
- Premium price
- Less aggressive lugs
- Heavier than some
The Falken Wildpeak A/T4W is in a different league when it comes to all-weather performance. It’s one of the few A/Ts in this size with a Three-Peak rating, and the engineering shows, owners consistently report strong grip in snow, sleet, and rain, without sacrificing dry-road stability. The tread design is optimized for heat resistance too, so it holds up well in desert climates where cheaper tires start chunking.
Yes, it’s the most expensive option here, but you’re paying for proven all-climate reliability. Compared to the Kenda Klever R/T, it’s slightly less aggressive off-road but more composed on long highway stretches. If you drive through mountain passes in winter or live where weather swings hard, this is the one I’d trust most. It’s the only tire here that truly doubles as a true all-weather workhorse.

Gladiator X COMP A/T
Strengths
- Aggressive tread
- Strong sidewall
- All-season capable
Trade-offs
- Moderate road noise
- Slightly stiffer ride
The Gladiator X COMP A/T stands out as a serious contender if you’re after a tire that won’t flinch at hard use. On paper, the dual influence of their M/T and A/T lineage makes sense, and owners consistently report solid on-road manners paired with dependable off-road bite. The two full plies and full sidewall turn aren’t just marketing fluff, they translate into real-world toughness, especially when crawling over sharp rock or airing down for traction.
I’d pick this over a pure R/T if you do more aggressive off-roading but still need daily drivability. Compared to the Terra Commander RTX, it trades a bit of on-road refinement for noticeably better sidewall defense and chunkier bite in the mud. It’s not the quietest tire out there, but the trade-off is worth it for the added durability.

Kanati Terra Commander RTX
Strengths
- Smooth highway ride
- Low road noise
- Stone ejectors
Trade-offs
- Limited mud traction
- Sidewall less puncture-resistant
- Not for hardcore off-roading
If on-road comfort is your top priority and your off-roading stays on the milder side, the Terra Commander RTX makes a strong case. The closely spaced lugs and stone ejectors are smart touches, owners praise its ability to stay quiet on long hauls while still offering enough bite for gravel roads and damp trails. The siped lugs help with wet grip, and the 3-ply sidewalls add a layer of toughness that’s rare at this comfort-focused end of the spectrum.
Compared to the brawny Gladiator X COMP, this tire feels more like a highway-tuned R/T hybrid. It won’t match the extreme durability of a true M/T, but for weekend adventures and daily driving, it’s one of the smoother operators in the 37-inch class. I’d recommend it over louder, stiffer options if your rig spends more time on pavement than on rock crawls.

Arisun Aresta R/T ZG07
Strengths
- Aggressive look
- High load rating
- 12-ply durability
Trade-offs
- Higher road noise
- Not Three-Peak rated
- Less refined on pavement
Let’s be clear: the Arisun Aresta R/T ZG07 is built to turn heads. The aggressive shoulder blocks and rugged terrain profile give trucks and Jeeps a mean stance straight out of the box. On paper, the 12-ply rating and Load Index 128 suggest serious load-carrying chops, and reviewers note it holds up well under heavy loads off-pavement.
But this is one of those tires where style and substance aren’t perfectly balanced. It’s louder than most A/Ts on highway, and while it handles mud and gravel decently, it doesn’t match the winter performance of Three-Peak certified rivals like the Sailun or Falken. If you want a tire that looks like it just came off a baja build, this delivers. But don’t buy it for refinement.

Mastertrack Badlands RT
Strengths
- Balanced on/off-road mix
- Aggressive styling
- 12-ply rating
Trade-offs
- No Three-Peak certification
- Average winter performance
- Limited owner feedback
The Mastertrack Badlands RT tries to be the middle ground between comfort and capability, and on paper, it’s compelling. The hybrid rugged-terrain design promises A/T-like manners on pavement with R/T aggression when you leave it. Owners report it’s quieter than expected for its look, and the 12-ply rating gives it an edge in load-bearing confidence.
But it doesn’t dominate in any one area. It’s not Three-Peak rated like the Sailun or Falken, and its sidewall protection isn’t as robust as the Gladiator’s. Still, for the buyer who wants a tough-looking tire without paying a premium, it’s a credible second-tier option. I’d consider it over the Arisun if you want slightly better on-road behavior without sacrificing too much off-road presence.

How We Picked These 37×12.50r20 all terrain tires
Rather than a hands-on lab test, my research focused on a detailed comparison of published specifications and features across these 37×12.50r20 tires. I weighed owner reviews from multiple sources, looking for recurring themes in both positive and negative feedback, alongside assessments from respected automotive publications. Years of experience with vehicle modifications and a focus on tire performance helped me apply category expertise to rank these options against key criteria for all-terrain capability and real-world usability.
For this size, durability and all-weather performance stood out as the most crucial factors. A tire in this class needs a robust construction to handle the weight of trucks and SUVs, both on and off-road. Equally important is the ability to provide consistent traction in a variety of conditions, from muddy trails to snowy highways. If you’re also considering other sizes, you might find our guide to 33×12.50R20 tires helpful.
Specifications reliably indicate construction details like ply ratings and tread depth, giving a solid baseline for expected durability. However, owner feedback truly reveals how a tire performs over time and in diverse conditions. Reputation matters; brands with a history of quality and consistent performance received greater consideration. For those looking at slightly smaller options, our analysis of 275/55R20 all-terrain tires provides additional insights.
How To Choose The 37×12.50r20 all terrain tires
Choosing the right all-terrain tire can dramatically change your truck’s capabilities and your driving experience.
A truly capable all-terrain tire balances on-road refinement with off-road grip. Look for robust construction with three-ply sidewalls, aggressive tread patterns that incorporate both large blocks and sufficient siping, and a rubber compound formulated for both durability and wet/snow traction. Consider the tire’s load rating and speed rating to match your vehicle and typical usage.
Tread Pattern & Terrain
The tread pattern is where all-terrain tires truly differentiate themselves. Some prioritize mud traction with widely spaced lugs, while others lean towards highway comfort with tighter patterns. I’ve seen that a good compromise is a hybrid design – think of the Mastertrack Badlands RT – which attempts to bridge the gap between aggressive off-road capability and on-road manners. Don’t get stuck on looks alone; consider where you’ll spend most of your time. A tire optimized for deep mud might wear quickly and be noisy on pavement.
Sidewall Strength & Durability
Sidewall strength is paramount, especially if you frequently venture off the beaten path. Rocks, roots, and other obstacles can easily damage a weaker sidewall, leading to flats or even blowouts. Tires like the Gladiator X COMP A/T are specifically built with reinforced sidewalls to resist punctures and abrasions.
Here’s what to look for in sidewall construction: * Ply Rating: Higher ply ratings generally mean stronger sidewalls (though it’s not a direct correlation to layers of material anymore). * Sidewall Compounds: Some tires use specialized rubber compounds in the sidewall for increased cut and chip resistance. * Turn-Over Tread: The way the tread wraps around the sidewall provides extra protection and grip when aired down for off-roading. This feature is especially helpful if you’re looking at similar offerings to the 35×12.50R20 tires.
A tire is only as good as its weakest point. Don’t skimp on sidewall protection if you plan on serious off-road use.
Balancing Comfort and Noise
Let’s be honest: most all-terrain tires will generate more road noise than a dedicated highway tire. However, some designs prioritize on-road comfort more than others. The Kanati Terra Commander RTX, for example, uses a tread pattern designed to minimize noise and offer a smoother ride. If you spend a lot of time on the highway, look for tires with features like stone ejectors and closely spaced lugs.

Frequently Asked Questions
Will 37×12.50r20 tires fit my truck without a lift?
Typically, no. Most trucks require a 2-3 inch lift to accommodate 37-inch tires and avoid rubbing during suspension compression or turning, though it depends heavily on your vehicle’s existing suspension and trim level.
What load range should I look for in a 37×12.50r20 all-terrain tire?
A load range of E is generally recommended for this size, as it provides the necessary strength and carrying capacity for most trucks and SUVs. This is especially true if you tow or haul heavy loads frequently.
How much more will a 37×12.50r20 tire affect my fuel economy?
Expect a decrease in fuel economy, likely between 1-3 mpg, due to the tire’s larger size and increased weight. Choosing a lighter tire within this size class and maintaining proper tire pressure can help minimize this impact.
Are 37×12.50r20 tires legal on the road?
Legality varies by location; however, most states allow these tires if your vehicle can safely accommodate them and they don’t extend beyond the fenders. Always check your local laws and regulations. For more information on the best all-terrain tires, visit all-terrain tire reviews.
How does ply rating relate to tire durability?
While once directly tied to the number of fabric layers, ply rating now indicates a tire’s load-carrying capacity and strength. A higher ply rating (like 10-ply or 12-ply) generally signifies a more durable tire, particularly for resisting punctures and damage from off-road hazards, and you can find durable LT all-terrain tires to help with this.
The Bottom Line
Choosing the right 37×12.50r20 all-terrain tire often comes down to balancing how you use your truck with how much you’re willing to spend. While features and specs are important, the Kenda Klever R/T KR601 consistently rises to the top as the strongest overall performer, offering a compelling mix of durability, traction, and reasonable on-road manners. It represents a solid investment for those who demand capability without excessive compromise.
For those prioritizing value, the Sailun Terramax R/T delivers impressive performance for the price, and the Gladiator X COMP A/T stands out if you absolutely need a tire that can withstand serious abuse. If a comfortable highway ride is paramount, the Kanati Terra Commander RTX is worth a close look. Don’t forget to explore options if you’re considering other sizes, such as these 285/60R20 tires.
Ultimately, remember that the tire’s specs are guides, not guarantees. A robust construction, a well-considered tread pattern, and a focus on matching the tire to your driving style will deliver far more benefit than chasing the highest load rating or the most aggressive look. And if you’re looking at different rim sizes, checking out the best tires for 20-inch wheels is a smart move.
