1. BFGoodrich Mud-Terrain T/A KM3: Best Overall
In our evaluation, the BFGoodrich Mud-Terrain T/A KM3 stands out as the top performer for serious off-roaders. Based on owner feedback and the spec sheets, the KM3 delivers outstanding traction in mud, rock, and sand thanks to its aggressive tread and self-cleaning lugs. The 3-ply sidewall construction provides excellent durability against trail hazards, and the 40,000-mile treadwear warranty adds peace of mind for those who drive their rig on the street.
However, the KM3 is not the best choice for daily drivers who prioritize a quiet ride. On-road noise is noticeably higher than all-terrain tires, and highway fuel economy may suffer slightly. If most of your driving is on pavement with occasional off-road trips, consider a more balanced tire. This tire is ideal for Jeep Wrangler, Ford Bronco, and truck owners who frequently tackle challenging trails.
- Mud-Terrain design with aggressive tread pattern for extreme off-road traction
- CoreGard Max technology for enhanced sidewall protection against punctures
- Mud-Phobic bars self-clean to maintain grip in sticky conditions
Pros: Exceptional off-road traction in mud and rocks; Durable sidewall resists cuts and abrasions
Cons: Noticeably louder on pavement compared to all-terrain tires
2. Nitto Trail Grappler M/T: Best for Mixed Use
We researched the Nitto Trail Grappler M/T as a strong contender for those who need a tire that performs well both off-road and on the highway. Based on owner feedback, the Trail Grappler offers a quieter ride than many competitors while still providing excellent mud and rock traction. The dual sidewall design allows users to choose a more aggressive or subtle look, and the stone ejectors help protect the tread from damage.
That said, in our evaluation, the Trail Grappler may not be the best for extreme rock crawling due to reports of tread chunking in sharp terrain. It is a great choice for overlanders and daily drivers who want a capable mud-terrain tire without sacrificing too much on-road refinement. If you primarily drive on pavement, an all-terrain might serve you better.
- Dual sidewall design offers customizable look and extra protection
- Stone ejectors prevent rock drilling between tread blocks
- Reinforced tread area for improved stability at higher speeds
Pros: Good balance of off-road traction and on-road comfort; Long tread life for a mud-terrain tire
Cons: Can be prone to chunking in very sharp rocks
3. Toyo Open Country M/T: Best for Durability
After comparing manufacturer data and owner experiences, the Toyo Open Country M/T earns high marks for durability. The 3-ply sidewall and deep tread make it one of the toughest 37×12.50R17 tires available, ideal for heavy trucks and frequent off-road use. Owners report long tread life even under heavy loads and in harsh conditions.
However, the trade-off is a stiff ride on pavement, which can be jarring on rough roads. Additionally, the lack of a treadwear warranty may be a concern for some buyers. This tire is best suited for those who prioritize off-road toughness over on-road comfort. If you do not need maximum durability and want a smoother daily drive, consider an all-terrain tire.
- Deep tread depth for long off-road life
- Reinforced shoulder blocks for improved stability
- Variable pitch tread pattern reduces road noise
Pros: Extremely durable and resistant to punctures; Excellent traction in deep mud and loose soil
Cons: Stiff ride on pavement, especially at low tire pressures
4. Cooper Discoverer STT Pro: Best Value
In our evaluation, the Cooper Discoverer STT Pro offers a compelling balance of off-road capability and value. Based on owner feedback, it performs well in mud and rocks while providing a quieter ride than some premium mud-terrain tires. The Armor Tek3 construction adds durability without a significant weight penalty, and the 40,000-mile warranty is a nice bonus.
However, some owners note that the tire feels less stable on pavement, especially during lane changes or in crosswinds. This tire is a solid choice for budget-conscious off-roaders who still want a capable mud-terrain. If you frequently drive at highway speeds, you may prefer a tire with more on-road refinement.
- Armor Tek3 construction for enhanced puncture resistance
- Stone block technology helps prevent stone retention
- Symmetric tread design allows for rotation flexibility
Pros: Competitive price for a 3-ply mud-terrain tire; Good off-road traction and self-cleaning ability
Cons: On-road handling can feel vague at highway speeds
5. Mickey Thompson Baja Boss M/T: Best for Rock Crawling
Based on owner feedback from hardcore off-roaders, the Mickey Thompson Baja Boss M/T is a top choice for rock crawling. The PowerPly XD sidewall is one of the toughest on the market, and the tread design provides incredible grip on slickrock and ledges. In our comparison, it excels in low-speed technical driving where precision traction matters most.
However, this tire is not designed for daily driving. It is loud on the highway and offers a harsh ride, which can be tiring on long trips. Additionally, the lack of a treadwear warranty reflects its niche focus. This tire is best for dedicated off-road vehicles that see limited pavement time. If you need a versatile tire for daily use, look elsewhere.
- PowerPly XD sidewall technology for extreme cut resistance
- Deep tread with aggressive shoulder lugs for rock gripping
- Stone ejectors reduce rock drilling
Pros: Exceptional traction on rocks and technical terrain; Very tough sidewall resists cuts and abrasions
Cons: Rough and noisy on pavement
6. Falken Wildpeak M/T: Best for Wet Conditions
After researching owner feedback, the Falken Wildpeak M/T stands out for its on-road manners and wet performance. The deep sipes and heat diffuser technology help maintain grip in rain and light snow, making it a more versatile choice for those who encounter varied conditions. It is also one of the quieter mud-terrain tires we evaluated.
However, in our evaluation, the Wildpeak M/T does not match the extreme mud traction of more aggressive tires like the BFGoodrich KM3 or Mickey Thompson Baja Boss. If you frequently drive in deep, sticky mud, you may want a tire with more aggressive tread. This tire is a good fit for overlanders and daily drivers who want mud-terrain capability without sacrificing too much comfort.
- Heat diffuser technology reduces heat buildup for longer life
- Deep sipes improve wet traction and snow performance
- Optimized tread pattern for reduced road noise
Pros: Good wet and snow traction for a mud-terrain tire; Quieter than many competitors on pavement
Cons: Less aggressive in deep mud compared to dedicated mud tires
7. Interco Super Swamper IROK: Best for Extreme Off-Road
For those who need the ultimate mud tire, the Interco Super Swamper IROK is a legendary choice. Based on owner feedback from extreme off-roaders, this tire excels in deep mud, swamps, and soft soil where other tires struggle. The large tread voids and ramped blocks provide exceptional self-cleaning, allowing the tire to maintain grip in the worst conditions.
However, the IROK is not suitable for daily driving. It is extremely loud on pavement, offers minimal stability at highway speeds, and wears quickly on hard surfaces. The Load Range C and 2-ply sidewall also mean it is less durable against sharp rocks. This tire is strictly for off-road-only vehicles or trailers. If you need a tire that can handle both trail and street, skip this one.
- Extremely aggressive tread with large voids for mud clearing
- Ramped tread blocks for better self-cleaning
- Available in bias ply for maximum off-road performance
Pros: Unmatched traction in deep mud and loose terrain; Lightweight design improves off-road agility
Cons: Poor on-road behavior: loud, harsh, and unstable at highway speeds
Frequently Asked Questions
What does 37×12.50R17 mean?
The 37×12.50R17 size means the tire is approximately 37 inches tall, 12.50 inches wide, and fits a 17-inch wheel. The ‘R’ indicates radial construction. This size is common for lifted trucks and SUVs.
Will 37×12.50R17 tires fit my vehicle?
Fitment depends on your vehicle’s suspension, lift, and wheel offset. Most trucks and SUVs require a lift kit of at least 2-4 inches to clear 37-inch tires without rubbing. Always check clearance at full steering lock and suspension articulation.
What load range do I need for 37×12.50R17 tires?
Most 37×12.50R17 tires come in Load Range D or E. Load Range E (10-ply rated) is common for heavy-duty trucks and towing, while Load Range D is lighter. Choose based on your vehicle’s weight and usage. Always match or exceed the OEM load rating.
How long do 37×12.50R17 mud-terrain tires last?
Tread life varies widely based on driving habits, terrain, and maintenance. Aggressive mud-terrain tires typically last 30,000 to 50,000 miles on pavement. Some brands offer treadwear warranties of 40,000 miles or more. Regular rotations and proper inflation extend life.
Are 37×12.50R17 tires good for daily driving?
Mud-terrain tires can be used daily, but they are louder and less comfortable than all-terrain tires. They also reduce fuel economy. If you drive mostly on pavement, consider an all-terrain tire like the BFGoodrich All-Terrain T/A KO2 for a better balance.
Our Verdict
After researching and comparing the top 37×12.50R17 tires, the BFGoodrich Mud-Terrain T/A KM3 is our top pick for its exceptional off-road traction and durability. For a more balanced tire that works well on and off road, the Nitto Trail Grappler M/T is an excellent runner up.
