1. BFGoodrich Mud-Terrain T/A KM3: Best Overall
In our evaluation, the BFGoodrich Mud-Terrain T/A KM3 stands out for its exceptional off-road performance and durability. Based on owner feedback and the spec sheets, the KM3 offers a 5% improvement in mud traction over its predecessor, thanks to a new tread compound and mud-phobic bars that eject debris. The 3-ply sidewall with CoreGard technology provides outstanding resistance against punctures and abrasions, making it a favorite for rock crawling and trail running. On the road, the tire is M+S rated and handles reasonably well, though some highway drone is expected.
However, the KM3 is not ideal for those who prioritize a quiet, comfortable highway ride. The aggressive tread pattern generates noticeable noise at speeds above 55 mph, and the tire’s weight can affect fuel economy. If you spend most of your time on pavement, consider a more road-friendly all-terrain. But if you demand maximum off-road capability and durability, the KM3 is a top choice.
- Mud-Terrain design with advanced tread compound for extreme off-road traction
- Reinforced sidewall with CoreGard technology resists punctures and cuts
- M+S rated with decent on-road manners for a mud tire
Pros: Excellent traction in mud and rock; Very durable sidewall
Cons: On-road noise is noticeable at highway speeds
2. Nitto Ridge Grappler: Best Hybrid
The Nitto Ridge Grappler is a hybrid tire that we researched and compared for its balance of on-road comfort and off-road capability. Based on owner feedback and the spec sheets, it features a unique tread pattern with alternating lug and groove elements that provide solid traction on trails while maintaining a quiet, smooth ride on pavement. The variable pitch tread blocks help cancel out noise, and the dual sidewall design adds protection against cuts. With a tread depth of 18/32 inches, it offers long tread life for a 37 inch tire.
That said, the Ridge Grappler is not a pure mud tire. In deep, sticky mud, it may struggle compared to more aggressive options like the KM3. Owners report that it performs best on gravel, dirt, and light trails. If you frequently encounter severe mud or rock crawling, this tire might not be the best fit. But for daily drivers who want occasional off-road fun without sacrificing highway comfort, it is an excellent choice.
- Hybrid tread pattern blends all-terrain and mud-terrain features
- Variable pitch tread blocks reduce road noise for a comfortable ride
- Dual sidewall design offers protection and style
Pros: Quiet on-road for a hybrid tire; Good off-road traction in most conditions
Cons: Not as aggressive in deep mud as dedicated mud tires
3. Toyo Open Country M/T: Best for Durability
In our evaluation, the Toyo Open Country M/T is a standout for durability and longevity. Based on manufacturer specifications and owner feedback, it features a deep 19/32 inch tread depth and a robust 3-ply sidewall that resists punctures and cuts. The tread compound is formulated to resist chipping and tearing, and many owners report getting 40,000 miles or more from a set. It also performs well in off-road conditions with good self-cleaning in mud and snow.
However, the Toyo M/T is one of the heavier tires in its class, which can negatively affect acceleration, braking, and fuel economy. It also generates more road noise than some competitors. If you prioritize a lightweight tire or a quiet cabin, you may want to look elsewhere. But for those who need a tire that can withstand harsh terrain and last a long time, the Toyo Open Country M/T is a solid investment.
- Deep tread depth and tough compound for long tread life
- 3-ply sidewall with reinforced shoulder resists impacts
- Excellent self-cleaning in mud and snow
Pros: Exceptional tread life for a mud tire; Very tough construction
Cons: Heavy and can impact fuel economy
4. Goodyear Wrangler Duratrac: Best for Snow
The Goodyear Wrangler Duratrac is a favorite among owners who face harsh winters. Based on our research, it is one of the few 37 inch tires with the Three-Peak Mountain Snowflake (3PMSF) rating, indicating superior snow traction. The Tractive Groove technology and multi-angle sipes provide grip on snow and ice, while the Durawall reinforced sidewall offers decent protection. On dry pavement, the tire rides smoothly with moderate noise levels for an all-terrain.
However, the Duratrac’s sidewall is not as tough as 3-ply options like the Toyo M/T or BFGoodrich KM3. In rocky terrain, owners report a higher risk of sidewall cuts. If you frequently wheel in sharp rocks, you may want a more robust tire. But for those who prioritize snow performance and balanced on-road manners, the Duratrac is a top contender.
- Severe snow service rated with 3PMSF symbol for winter traction
- Tractive Groove technology provides grip in snow and slush
- Reinforced sidewall with Durawall technology resists punctures
Pros: Excellent snow and ice traction; Good on-road comfort
Cons: Sidewall is less durable than 3-ply competitors
5. Cooper Discoverer STT Pro: Best Value
The Cooper Discoverer STT Pro offers a compelling value proposition for budget-conscious off-roaders. In our comparison, it provides a 3-ply sidewall and deep 19/32 inch tread depth at a lower price point than many rivals. Owner feedback highlights its strong traction in mud and rocks, and the Armor-Tek3 construction gives confidence in tough conditions. The stone and mud ejectors help maintain performance by clearing debris from the tread.
On the downside, the STT Pro is noticeably louder on the highway than hybrid tires like the Nitto Ridge Grappler. Also, some owners report uneven wear if not rotated regularly. If you can tolerate some noise and are diligent about maintenance, this tire delivers excellent capability for the money. But if a quiet ride is a priority, consider a less aggressive option.
- Armor-Tek3 construction with 3-ply sidewall for durability
- Stone and mud ejectors keep tread clean
- Deep tread depth for long wear
Pros: Competitive price for a 3-ply tire; Good off-road traction
Cons: On-road noise is higher than some competitors
6. Mickey Thompson Baja Boss M/T: Best for Rock Crawling
The Mickey Thompson Baja Boss M/T is engineered for serious rock crawling. Based on our research, its PowerPly XD sidewall technology provides outstanding cut and abrasion resistance, and the tread pattern is designed to grip rocks and eject mud efficiently. Owners who wheel in extreme terrain praise its ability to climb slick rock and maintain traction at low air pressures. The reinforced bead area helps prevent de-beading during aggressive maneuvers.
However, the Baja Boss M/T comes at a premium price, and its on-road performance is compromised. The tire is heavy, noisy, and not as comfortable on pavement. If you do not regularly tackle hardcore trails, you may not need this level of capability. But for dedicated rock crawlers, it is a top-tier choice that justifies its cost with specialized performance.
- PowerPly XD sidewall technology for extreme cut resistance
- Optimized tread pattern for rock traction and self-cleaning
- Reinforced bead area for low-pressure crawling
Pros: Exceptional rock crawling traction; Very tough sidewall
Cons: Expensive for the performance
7. Falken Wildpeak M/T: Good All-Rounder
The Falken Wildpeak M/T is a budget-friendly mud-terrain tire that offers reasonable off-road performance for occasional trail use. In our evaluation, it features 3D Canyon sipes that enhance wet traction, and the heat diffuser technology helps prevent heat-related damage during extended highway driving. Owner feedback indicates that it performs adequately in mud and gravel, though not as well as premium options. The tread pattern includes stone ejectors to keep debris from packing.
However, the Wildpeak M/T has a 2-ply sidewall, which is less resistant to cuts and punctures than 3-ply competitors. Several owners report sidewall damage in rocky terrain. If you frequently wheel in sharp rocks, this tire may not be reliable. It is best suited for light off-road use and budget-conscious buyers who want a 37 inch tire without breaking the bank.
- 3D Canyon sipe technology for improved traction on wet roads
- Heat diffuser technology reduces heat buildup
- Stone ejector ribs prevent stone retention
Pros: Good value for the price; Decent wet road traction
Cons: Sidewall durability is below average for the class

Do I need a lift to fit 37 inch tires?
Most vehicles require a suspension lift of at least 3-4 inches to clear 37 inch tires without rubbing. Wheel offset and backspacing also matter. Always check your vehicle’s fitment specifications and consider trimming or aftermarket fenders if needed.
Are 37 inch tires safe for highway driving?
Yes, when properly inflated and maintained. Tires like the Goodyear Wrangler Duratrac and Nitto Ridge Grappler are designed for highway use with stable handling. However, aggressive mud tires may have reduced wet traction and longer stopping distances. Always drive within the tire’s speed rating and load capacity.
What is the difference between load range E and load range D in 37 inch tires?
Load range E tires have a higher load capacity (typically 3,190 lbs per tire) and stiffer sidewalls than load range D (around 2,830 lbs). For heavy trucks and frequent off-road use, load range E offers better support and puncture resistance. Load range D may provide a slightly softer ride but is less durable.
