10 Best 37×12.50r20 All Terrain Tires in 2026

The 50,000-mile treadwear rating means you can expect long service life across varied conditions, from daily pavement to weekend trails. Its Three-Peak Mountain Snowflake certification provides legitimate all-weather capability, including winter driving, while the R speed rating supports highway use. This blend of durability, winter traction, and highway manners makes it a versatile choice for drivers who need one tire to handle a mix of road, weather, and light off-road use without frequent swapping.

The trade-off for that balanced performance is in ultimate load capacity. Its 126 load index is solid but falls short of the 128 or F-rated tires in the guide, like the Kenda Klever R/T. The whole set weighs 264 pounds, so mounting will need some muscle or professional help. If your primary need is maximum payload for heavy towing or gear, a higher-rated tire might be a better fit. For a do-it-all tire that won’t wear out quickly, the Terra Hunter X/T 2’s specifications are hard to beat.

A 128R load rating and three full carcass plies signal a tire built to handle heavy loads and resist punctures off-road. The Klever R/T is for drivers who face deep mud, packed snow, and icy roads regularly. Its interlocking tread blocks and high sipe density are engineered to bite into loose and slippery surfaces, while the ability to add studs provides a concrete option for extreme ice.

That focus on severe conditions comes with a trade-off. The 69-pound weight and aggressive design will likely translate to more hum on the highway compared to a less specialized all-terrain like the General Grabber A/TX. Choose this Kenda when winter and mud performance are non-negotiable, and you’re willing to accept some on-road refinement for that capability.

The 3-Peak Mountain Snowflake rating is the key spec here, meaning this tire is built for legitimate year-round use, including winter conditions. That makes the Delinte Centurion X/T a strong candidate for drivers who see varied weather but still want aggressive off-road capability. Its concave shoulder design and multi-directional grip pattern are engineered to bite into loose surfaces and handle quick steering inputs, which suits someone navigating a mix of pavement, gravel, and snowy trails.

Weighing 84.8 pounds, the Delinte Centurion X/T is a physically substantial tire. That mass translates to more rotating inertia, which can affect acceleration and fuel economy. This positions it as a heavy-duty, four-season workhorse rather than a lightweight efficiency play. You get a tire built for severe service and winter weather, but you’ll feel its presence in every rotation.

A 50,000-mile treadwear rating suggests the General Grabber A/TX is built for drivers covering substantial distances. This all-terrain tire is studdable for all-season traction, a concrete advantage in regions with severe winters where adding studs is a legal traction upgrade. Its 10-ply construction and load index of 126 support up to 3748 pounds per tire, meaning it’s built for the demands of light trucks, including towing and hauling.

This tire weighs 73 pounds, a substantial mass that demands a suitable vehicle and consideration for suspension components. Among similar 37-inch tires, weights vary; for example, the AMP Terrain Attack A/T is listed at 55 pounds, while the Delinte Centurion X/T is 84.8 pounds. The General tire’s specification places it in the middle of this range, representing a trade-off for the driver.

Weighing 55 pounds, the AMP Terrain Attack A/T is a notably lighter option in the 37-inch all-terrain class, which directly helps preserve your truck’s acceleration, braking, and fuel economy compared to many heavier competitors. This makes it a strong fit for drivers who want the aggressive look and capability of a 37-inch tire but are mindful of unsprung weight and daily driving manners. Its 10-ply E-load range construction and all-season rating suggest it’s built to handle towing and payloads reliably across three seasons.

When you compare it directly to a more engineered option like the General Grabber A/TX, the AMP leans more toward dependable, straightforward utility. This tire gets the core job done without adding excessive rotational mass, positioning it as a practical choice over a feature-rich one.

The Arisun Aresta A/T ZG06 offers a serious 10-ply construction and a 3,748-pound load capacity, which is essential for heavy light trucks and towing. This makes it a solid choice for someone who needs to reinforce just the drive axle of their vehicle with a durable, all-season tire. You get a capable core specification without the commitment of a full four-tire set, which is perfect for targeted upgrades or staggered replacements.

A set of two tires means these are not a complete solution for outfitting all four corners of a vehicle at once. The Arisun Aresta A/T ZG06 is built for light trucks with a 10-ply E load range, supporting up to 3,748 pounds per tire for heavy loads. Its Q speed rating is certified for 99 mph, which is sufficient for highway driving under ideal conditions.

The Predator New Mutant X-AT’s most defining feature is its aggressive tread pattern, engineered directly for superior off-road traction. This makes it a prime candidate for truck and SUV owners who prioritize capability in mud, rocks, and loose terrain over absolute pavement refinement. The 12-ply F load rating backs up that aggressive look with a construction tough enough for heavy loads and punishing trails. If your driving style leans more toward conquering obstacles than cruising highways, this tire’s design philosophy aligns perfectly.

Each Predator New Mutant X-AT tire weighs 84.8 pounds, a substantial figure that adds significant unsprung weight to your vehicle. This mass can affect acceleration and braking dynamics compared to lighter options. Its aggressive tread design and advanced all-terrain compound are engineered for improved traction both on and off-road, according to the manufacturer.

The dense siping and rigid block design of the Terrain King tread prioritize confident traction when the pavement is wet. This focus makes the Radar Renegade A/T a logical choice for drivers who face frequent rain and need an all-terrain that doesn’t compromise wet-road manners. Its temperature-adaptive compound and structural tie-bars aim to maintain that stability while resisting damage, suiting a daily-driven truck that sees occasional off-pavement use.

That capability comes with a tangible trade-off in weight and stiffness. The 12-ply construction and reinforced sidewalls deliver the cut resistance and load capacity for tough jobs, but they also mean you’ll feel more of the road. It’s a tire built for work and wet weather, not for a plush highway ride.

With a load index of 128, each Interco Super Swamper SSR supports up to 3968 pounds, a capacity matched by only one other tire in this group. This strength is derived from its 12-ply radial construction, which is designed for heavy-duty trucks, large SUVs with substantial payloads, or towing near maximum capacity. The tire suits a buyer whose primary concern is load security over just aggressive styling.

That capability comes with a tangible trade-off: at 82 pounds, it’s a notably heavy tire. This weight will place more demand on your vehicle’s suspension and can impact acceleration and braking compared to lighter options like the 69-pound Kenda Klever R/T. Choose the SSR when your needs are defined by brute strength and towing stability, and be prepared for the rotational mass that comes with it.

A 60,000-mile treadwear warranty is the standout feature here, signaling a tire built for longevity over pure off-road aggression. The Delinte Centurion A/T suits the driver who racks up highway miles but still wants the look and capability of a 37-inch all-terrain. Its 12-ply construction and 3PMSF snow rating mean it’s built to handle heavy loads and varied weather confidently, making it a solid choice for a daily-driven truck or SUV that sees occasional trail use.

The Delinte Centurion A/T carries a 60,000-mile treadwear rating, which means buyers can expect a long service life for daily driving and trips. Its 12-ply (F) radial construction and 128 load index support up to 3,968 pounds per tire, so it’s built to handle heavy loads from a light truck or SUV. With a Three-Peak Mountain Snowflake symbol, it is certified for use in severe snow conditions.
