1. BFGoodrich Mud-Terrain T/A KM3: Best Overall

The BFGoodrich Mud-Terrain T/A KM3 is a top contender in the 37×12.50R17 category. In our evaluation based on manufacturer specs and owner feedback, it delivers exceptional mud traction thanks to its Mud-Phobic bars that eject debris. The 3-ply sidewall provides excellent durability for rock crawling, and the tire maintains surprisingly composed road manners for a mud-terrain. Owners consistently report long tread life and strong resistance to chunking.
However, the KM3 commands a premium price, which may not suit budget-conscious buyers. Additionally, while on-road noise is lower than many competitors, it’s still noticeable at highway speeds. We recommend this tire for serious off-roaders who prioritize traction and durability over cost.
- Mud-Phobic bars self-clean to maintain traction in deep muck
- Sidewall armor with Terrain-Attack tread design for rock protection
- Excellent on-road manners with low road noise for a mud tire
Pros: Outstanding mud traction and self-cleaning; Durable sidewall resists cuts and punctures
Cons: Higher price point than many competitors
2. Nitto Trail Grappler M/T: Best for Heavy Trucks

The Nitto Trail Grappler M/T is a popular choice for heavy-duty trucks and SUVs. Based on our research of specifications and owner reviews, it offers a strong 3-ply sidewall and deep tread that performs well in mud and rocks. The dual sidewall design adds aesthetic versatility, and stone ejectors help prevent tread damage. On-road, the tire provides a relatively quiet ride for a mud-terrain, with stable handling at highway speeds.
However, some owners report that the tread can cup if rotations are neglected, which may shorten lifespan. The Trail Grappler also carries a higher price. We recommend it for full-size trucks and heavy rigs that need a robust tire capable of towing and off-road use, but it may be overkill for lighter vehicles.
- Dual sidewall design for protection and style
- Stone ejectors prevent stone drilling in tread
- Staggered shoulder lugs for enhanced traction in soft terrain
Pros: Excellent load capacity for heavy trucks; Good balance of off-road traction and on-road comfort
Cons: Tread can be prone to cupping if not rotated regularly
3. Toyo Open Country M/T: Best for Long Tread Life

The Toyo Open Country M/T is known for its durability and long tread life. In our analysis of owner feedback and spec sheets, the non-directional tread allows flexible rotation patterns, promoting even wear. The reinforced sidewall offers good protection against cuts, and the tire runs quieter than many competitors on pavement. Owners often report 40,000+ miles with proper maintenance, which is impressive for a mud-terrain.
However, in deep mud, the Open Country M/T doesn’t self-clean as aggressively as some rivals, which can reduce traction in extreme conditions. It’s best suited for drivers who spend a mix of highway and off-road time and want a tire that lasts, but hardcore mudders might want something more aggressive.
- Non-directional tread design allows tire rotation in any pattern
- Reinforced sidewall rubber for cut and chip resistance
- Excellent highway stability and even wear
Pros: Long tread life compared to many mud tires; Quiet on-road performance
Cons: Mud traction is good but not class-leading
4. Cooper Discoverer STT Pro: Best for Rock Crawling

The Cooper Discoverer STT Pro is engineered for extreme off-road conditions, particularly rock crawling. Based on manufacturer data and owner reports, its Armor-Tek3 construction provides outstanding resistance to cuts and punctures. The deep tread features mud scoops that help clear debris, and stone block technology reduces stone drilling. On the trail, the tire offers impressive grip on rocks and loose terrain.
However, the STT Pro is noticeably louder on the highway compared to more road-oriented mud tires. Additionally, tread life may be shorter if used predominantly on pavement. We recommend this tire for dedicated off-roaders who prioritize rock-crawling performance over on-road comfort.
- Armor-Tek3 construction for extreme cut and puncture resistance
- Deep tread with mud scoops for excellent traction
- Stone block technology to prevent stone retention
Pros: Exceptional rock-crawling grip; Very durable sidewall
Cons: Higher road noise than some competitors
5. Mickey Thompson Baja Boss M/T: Best for Mud Performance

The Mickey Thompson Baja Boss M/T is designed to excel in mud. Our research indicates that its aggressive tread pattern with large, scooped lugs clears mud effectively, providing strong forward traction. The PowerPly XD sidewall offers decent flexibility for off-road articulation, but it’s not as puncture-resistant as thicker sidewalls. On-road, the tire is reasonably quiet for a mud-terrain thanks to variable-pitch tread blocks.
However, some owners report sidewall damage in rocky terrain, so it may not be ideal for hardcore rock crawling. The tread life is also average. This tire is best for drivers who frequently encounter deep mud and want a tire that performs well there, but it may not hold up as well in abrasive conditions.
- PowerPly XD sidewall for strength and flexibility
- Tread pattern with large, scooped lugs for mud clearing
- Variable-pitch tread for reduced road noise
Pros: Excellent mud traction and self-cleaning; Good balance of off-road capability and on-road noise
Cons: Sidewall durability is not as high as some competitors
6. General Grabber X3: Best Value
The General Grabber X3 offers solid off-road performance at a more accessible price point. In our evaluation of specifications and owner feedback, it provides good mud and rock traction thanks to its deep tread and aggressive lugs. The Kindle Technology helps dissipate heat, potentially extending tire life. Many owners appreciate the value, noting that the tire performs admirably for its cost.
However, the ride quality on pavement is firmer and noisier than more expensive mud tires. Tread life is also shorter, especially with heavy vehicles. We recommend the Grabber X3 for budget-conscious off-roaders who don’t mind sacrificing some on-road comfort for capable trail performance.
- Kindle Technology for heat resistance and longevity
- Deep tread with aggressive shoulder lugs
- Stone bumpers to protect tread from stones
Pros: Great value for the price; Good off-road traction for the cost
Cons: On-road ride can be harsh; Tread wear faster than premium options
7. Falken Wildpeak M/T: Best for On-Road Manners

The Falken Wildpeak M/T prioritizes on-road comfort without completely sacrificing off-road capability. Based on owner reviews and spec analysis, it features 3D Canyon sipes that improve wet traction, and the tread pattern is optimized for low noise. Many drivers find it one of the quietest mud-terrain tires available, making it suitable for daily driving. The heat diffuser technology helps maintain consistent performance.
However, in deep mud, the Wildpeak M/T doesn’t clean out as well as more aggressive designs, limiting traction. The sidewall is also less rugged, which can be a drawback in rocky terrain. We recommend this tire for those who spend most of their time on pavement but want a mud tire for occasional light off-road use.
- 3D Canyon sipe technology for enhanced wet traction
- Heat diffuser technology for cooler running temperatures
- Optimized tread pattern for reduced road noise
Pros: Very quiet and comfortable on-road; Good wet traction for a mud tire
Cons: Mud performance is only adequate; Sidewall less aggressive for rock crawling
Frequently Asked Questions
What is the difference between a mud-terrain and all-terrain tire?
Mud-terrain (M/T) tires have deeper, more aggressive tread patterns with larger voids to dig into soft surfaces and eject mud. They typically feature stronger sidewalls for off-road protection. All-terrain (A/T) tires offer a compromise with moderate off-road capability and better on-road comfort, noise, and tread life.
Can I use 37×12.50R17 mud tires on stock suspension?
Most stock vehicles require a lift kit (typically 2-6 inches) to fit 37-inch tires without rubbing. Always check your vehicle’s clearance and consult a professional. Even with a lift, you may need wheel spacers or aftermarket wheels with proper offset.
How long do 37×12.50R17 mud tires typically last?
Tread life varies widely based on driving habits, terrain, and tire construction. On average, mud-terrain tires last between 25,000 and 40,000 miles. Rotating tires every 5,000-6,000 miles and maintaining proper inflation can extend lifespan.
Are 37×12.50R17 mud tires safe for highway driving?
Yes, when properly maintained. Look for tires with a load range E (10-ply rating) for stability. Be aware that mud tires can be noisier and may have reduced wet traction compared to all-terrains. Always check speed ratings and ensure your wheels are balanced.
Do I need special wheels for 37×12.50R17 tires?
You need 17-inch diameter wheels with a width typically between 8.5 and 11 inches. Confirm the wheel offset and backspacing to avoid rubbing on suspension components or fenders. Many off-roaders choose aftermarket wheels with proper specifications.
