10 Best 37 Inch Tires in 2026

The BFGoodrich Mud Terrain T/A KM3’s 5% improvement in mud traction over its predecessor is the core of its design, translating directly to forward momentum when you’re buried axle-deep. Its Krawl-TEK compound bites into rock surfaces for confident climbs, while the reinforced sidewalls are built to withstand sharp impacts. This tire is for the dedicated off-roader whose primary concern is conquering the most challenging, loose, and technical terrain, accepting that its capabilities are specialized. It prioritizes extreme performance over pavement manners.

Weighing 82.4 pounds, this tire’s mass contributes to overall vehicle unsprung weight. Its Terrain-Attack tread pattern with massive tread blocks is engineered for grip in muddy or soft soil conditions, a focus that differs from tires designed for more balanced all-terrain or highway use. For light trucks, SUVs, and crossovers used primarily off-road, the KM3’s enhancements target traction in extreme environments.

A severe winter snowflake rating means this tire provides legitimate all-season capability, not just fair-weather off-roading. That three-peak certification, combined with its interlocking tread design, makes the KO2 a prime candidate for drivers who need one set of tires to handle everything from daily commutes in snow to weekend trail explorations. It’s built for the 4×4, light truck, or SUV owner who values predictable handling and traction across a wide range of surfaces without needing to swap tires for winter.

The trade-off for its versatile all-terrain design and winter certification is weight and load capacity. Its 116S load and speed rating places it in a lighter-duty category compared to something like the Nitto Trail Grappler All-Terrain Tire, which carries a higher 124Q rating. For heavy hauling or high-speed desert running, that difference in construction and rating is significant. The KO2 prioritizes balanced, year-round performance over maximum brute strength.

Mickey Thompson backs the Baja Boss A/T with a 50K mile limited treadwear warranty, which points directly to its design for lasting use. The asymmetric tread pattern is optimized for reduced noise and on-road handling, while the T1 compound targets wet braking and cold weather traction. A Three-Peak Mountain Snowflake designation on this size confirms it meets severe snow service performance standards.

That durability comes with mass, as this tire weighs 77.2 pounds. For comparison, the listed BFGoodrich All-Terrain T/A KO2 in a similar size is 64.8 pounds. The Powerply XD construction adds heavier denier cord for puncture resistance and stability, and Extreme Sidebiters are included for off-road traction and sidewall protection.

Sidewall armor ensures the sidewall remains protected from impacts, which is critical when crawling over sharp rocks or through deep ruts where punctures are a constant threat. The GEO-SHIELD technology builds on that with a focus on superior durability, making this tire a solid choice for drivers who prioritize survival in punishing off-road conditions. Its optimized void ratio and sipes are designed to improve braking distance and traction, a welcome feature when navigating slick, muddy trails.

Weighing 74.3 pounds, the Yokohama Geolandar M/T G003 is a substantial piece of hardware for a 37-inch tire, a factor buyers should consider for their vehicle’s suspension and overall unsprung weight. This mud-terrain design is inherently more specialized for severe conditions than a general all-terrain tire. Its wide flat profile is engineered to distribute driving pressure evenly, which Yokohama states aims for longer tread wear in off-road use.

With a tread design that pairs mud-terrain shoulder blocks with an all-terrain center, the Atturo Trail Blade X/T is engineered for drivers who split their time evenly between pavement and trail. The linked center blocks reduce squirm on the highway for a composed ride, while the angled shoulder lugs dig in off-road. It backs this dual-purpose design with a substantial 45,000-mile warranty and up to 18/32nds of tread depth. This makes it a solid choice for someone who needs one tire to handle a weekly mix of commuting and weekend adventures without drastic compromises.

This balance is inherent to the hybrid category. While its shoulder blocks provide good loose-terrain bite, a dedicated mud-terrain like the Yokohama Geolandar M/T G003 will have more aggressive void space for extreme conditions. Conversely, the X/T’s highway manners are helped by its alternating sipes, but a pure all-terrain like the BFGoodrich All-Terrain T/A KO2 might offer a slightly quieter and more efficient on-road experience. You’re getting capable performance in both worlds, not dominance in one.

A 3527-pound load capacity per tire is the concrete reason to choose the Terra Hunter X/T. This 12-ply F-rated construction is built for trucks carrying serious weight or towing heavy trailers, where sidewall strength and puncture resistance are non-negotiable. It suits drivers who prioritize maximum payload and toughness above all else, backed by an all-season rating for year-round capability. The 50,000-mile treadwear expectation suggests a focus on longevity within the extreme-terrain category.

That capability comes with significant trade-offs.

Deep sipes cut into the tread blocks are the key feature here, actively channeling water away to maintain contact on rain-slicked roads. This design makes the Trail Grappler a strong choice for drivers who face unpredictable weather but still want an aggressive all-terrain look. It suits someone who needs dependable wet-weather manners without sacrificing the off-road appearance.

Weighing 83.8 pounds, the Nitto Trail Grappler carries more unsprung mass than several all-terrain rivals, which can influence ride comfort and fuel consumption. Its reinforced shoulder grooves and deep sipes are designed for all-season and wet-surface performance. The balanced void ratio aims to clear debris for consistent off-road traction.

With a load range F rating, this tire is designed to carry heavy loads, making it suitable for fully loaded trucks or those with significant modifications. Its 37-inch overall diameter gives it substantial ground clearance for navigating obstacles off-road. This mud-terrain pattern is a heavy-duty choice for drivers prioritizing capability over a quiet highway ride.

That load capacity comes with a weight penalty. At 82 pounds, each tire adds considerable rotating mass, which can impact vehicle acceleration, braking, and fuel efficiency. Among similarly sized tires, its weight is comparable to other mud-terrain options like the BFGoodrich KM3 and heavier than many all-terrain tires. It’s a purpose-built option for demanding off-road conditions.

A 55-pound weight for a 37-inch all-terrain tire is a tangible advantage, making it easier to handle during installation and reducing unsprung mass on your truck. This tire is built with a 10-ply E-rated structure, so it has the toughness for light-duty work and off-pavement exploration without the extreme heft of a dedicated mud-terrain. The all-season compound and tread design aim for a balanced mix of capability. For the driver who needs a functional 37-inch all-terrain tire that won’t break the bank or their back during mounting, this specification sheet presents a compelling case.

Tire load capacity is defined by its index, and the AMP Terrain Attack A/T carries a 126 rating. This rating is adequate for standard-duty towing and payloads on many half-ton trucks. For owners who frequently operate near a vehicle’s maximum capacity, other tires in the 37-inch category, such as the Falken Wildpeak R/T01, have a higher 128 load index.

It’s the right call if you’re aiming for maximum tire height without pushing your fenders out with a wider stance. The E-load rating means it’s built to handle the weight of a built-up truck or SUV reliably. This combination makes it a prime candidate for enthusiasts who prioritize a tall, aggressive look while navigating narrow trails or fitting within modified factory wheel wells.

That lean profile is a trade-off, though. Compared to a tire like the BFGoodrich KM3, which is over two inches wider, the Wildpeak R/T01 has less surface area. You gain precise fitment at the expense of some potential flotation.
