1. BFGoodrich All-Terrain T/A KO2: Best All-Terrain
The BFGoodrich All-Terrain T/A KO2 is our top pick for an all-terrain tire that works well both on and off the pavement. In our evaluation, it excels in durability with a tough sidewall and a 50,000 mile treadwear warranty. Owner feedback consistently highlights its long life and reliable traction in light off-road conditions and snow. However, it is more expensive than many competitors, so budget-conscious buyers may want to look elsewhere.
If you primarily drive on pavement with occasional trail use, the KO2 is a strong choice. But if you need serious mud performance, a dedicated mud-terrain tire like the Goodyear Wrangler MT/R might be better suited. Some owners report that the KO2 can be prone to chunking in rocky terrain, so hardcore off-roaders should consider a more aggressive tire.
- Excellent balance of on-road comfort and off-road capability
- Serrated shoulder design for improved traction in mud and snow
- 3D sipes and interlocking tread pattern for enhanced stability
Pros: Long tread life with mileage warranty; Quiet on highway
Cons: Premium price point, not budget-friendly
2. Goodyear Wrangler MT/R with Kevlar: Best Mud-Terrain
The Goodyear Wrangler MT/R with Kevlar is our top pick for a mud-terrain tire. Based on owner feedback and spec sheets, the Kevlar reinforcement provides outstanding puncture resistance in rocky terrain. The aggressive tread digs deep in mud and snow, making it a favorite among off-road enthusiasts. However, on-road manners suffer: it is noticeably louder and less comfortable than all-terrain tires, and tread life is shorter.
If your driving is mostly off-road or you live in a rural area with soft terrain, this tire is a great choice. But if you commute daily on pavement, the noise and wear may be deal-breakers. Some users also report balancing issues, so ensure proper mounting and balancing at installation.
- Kevlar reinforced sidewalls for cut and puncture resistance
- Deep, aggressive tread pattern for extreme mud traction
- Self-cleaning shoulder blocks to shed mud
Pros: Exceptional off-road grip in mud and rocks; Durable sidewall construction
Cons: Noisy on highway, less comfortable ride; Tread life shorter than all-terrain tires
3. Cooper Discoverer STT Pro: Best for Rock Crawling
The Cooper Discoverer STT Pro is designed for serious off-road use, especially rock crawling. Our research shows its Armor Tek3 construction with a 3-ply sidewall offers exceptional resistance to cuts and punctures. Owner feedback praises its grip on slick rocks and in deep mud. However, on-road comfort is compromised; the tire is stiff and can be noisy. Some owners report balancing challenges, so a reputable installer is recommended.
If you prioritize off-road performance over on-road comfort and plan to tackle challenging trails, the STT Pro is a solid pick. But for daily driving, consider a more road-friendly option like the BFGoodrich KO2. Also, tread life may be shorter for highway use.
- Armor Tek3 construction for extreme cut and chip resistance
- Stone ejectors to prevent rock drilling
- Mud scoops for enhanced traction in deep muck
Pros: Excellent rock crawling traction; Very durable sidewall
Cons: Stiff ride on pavement; Can be difficult to balance
4. Toyo Open Country A/T III: Best for Highway and Light Off-Road
The Toyo Open Country A/T III is a strong all-terrain tire that prioritizes on-road comfort and longevity. In our evaluation, it offers a 55,000 mile treadwear warranty and excellent wet traction thanks to the silica compound. Owner feedback confirms a quiet, smooth ride on the highway, making it a great choice for daily drivers. Off-road, it handles gravel and dirt roads well but struggles in deep mud or rock crawling.
If you spend most of your time on pavement and only venture onto light trails, this tire is a good value. However, if you need serious off-road capability, look at the Goodyear MT/R or Cooper STT Pro. Some owners note that the sidewall is less durable than competitors, so avoid sharp rocks.
- Silica-enhanced tread for improved wet traction and fuel economy
- Stone and mud ejectors to protect tread
- Comfortable and quiet on highway
Pros: Long tread life warranty; Quiet and smooth ride
Cons: Less aggressive off-road traction than MT tires; Not ideal for heavy mud
5. Firestone Destination M/T2: Best Value Mud-Terrain
The Firestone Destination M/T2 offers a budget-friendly entry into mud-terrain tires. Based on our research, it provides good traction in mud and loose soil, but its 2-ply sidewall is less durable than competitors. Owner feedback indicates that while it performs well off-road, it wears faster and becomes noisier over time. The 40,000 mile warranty is lower than some all-terrain options.
If you need a mud-terrain tire for occasional off-road use and want to save money, this is a reasonable choice. But for frequent off-roading or heavy loads, consider a more robust tire like the Goodyear MT/R. Some owners report balancing issues, so check for vibrations after installation.
- Aggressive tread with large shoulder blocks for mud traction
- Stone ejectors to prevent stone retention
- Reinforced bead area for durability
Pros: Affordable price point for a mud-terrain; Decent off-road traction
Cons: Shorter tread life than premium MT tires; Noise and vibration on highway
6. Nitto Ridge Grappler: Hybrid Terrain Best
The Nitto Ridge Grappler is a hybrid tire that aims to blend on-road comfort with off-road capability. In our evaluation, it offers a quieter ride than most mud-terrain tires but still provides good traction in mud and snow. However, some owners report that tread life is not as long as advertised, and the 2-ply sidewall is prone to cuts in rocky terrain. It works best for light to moderate off-road use.
If you want an aggressive look without sacrificing too much on-road comfort, the Ridge Grappler is a decent middle ground. But for heavy off-roading or loads, a tire with a 3-ply sidewall is safer. Some users also note that balancing can be tricky, so professional installation is advised.
- Hybrid tread pattern combining all-terrain and mud-terrain features
- Variable pitch tread blocks to reduce noise
- Stone ejectors and mud scoops
Pros: Versatile performance on and off road; Good looks with aggressive tread
Cons: Sidewall less durable than 3-ply competitors; Tread life shorter than expected for some users
7. Mickey Thompson Baja Legend MTZ: Off-Road Specialist
The Mickey Thompson Baja Legend MTZ is a dedicated mud-terrain tire that excels in deep mud and soft terrain. Our research indicates that its open tread pattern provides excellent self-cleaning, but at the cost of on-road refinement. Owner feedback frequently mentions excessive noise and a rough ride on pavement. Tread life is also a concern, with many users reporting premature wear. The price is relatively high for a 2-ply sidewall tire.
This tire is best for off-road enthusiasts who trailer their vehicle to trails and prioritize mud performance over everything else. If you drive daily on pavement, skip this pick. Some owners also note that balancing can be challenging, so be prepared for potential vibrations.
- Deep, open tread pattern for extreme mud traction
- Reinforced shoulder for durability
- Self-cleaning design
Pros: Excellent mud performance; Good for rock crawling with proper air down
Cons: Very noisy and harsh on pavement; Short tread life and expensive for what you get
Frequently Asked Questions
What does 31×10.5R15 mean?
31 is the overall diameter in inches, 10.5 is the section width in inches, and R15 means it fits a 15 inch rim. This size is commonly used on Jeep Wranglers, Toyota 4Runners, and other SUVs and trucks.
Can I use 31 inch tires on a stock Jeep Wrangler?
On a stock Jeep Wrangler TJ or YJ, 31 inch tires often fit without a lift, but may rub at full flex. On newer models like JK or JL, a small lift or trimming may be required. Always check your vehicle’s clearance before purchasing.
What is the difference between all-terrain and mud-terrain tires?
All-terrain tires (like the BFGoodrich KO2) are designed for a balance of on-road comfort and off-road capability, with longer tread life and quieter ride. Mud-terrain tires (like the Goodyear MT/R) have deeper, more aggressive tread for maximum traction in mud and rocks, but are noisier and wear faster on pavement.
How long do 31 inch tires typically last?
Tread life varies by type and driving habits. All-terrain tires often have 40,000 to 55,000 mile warranties, while mud-terrain tires typically last 30,000 to 40,000 miles. Proper inflation, rotation, and alignment can extend life.
Do I need to regear for 31 inch tires?
For most vehicles, 31 inch tires are a mild upgrade and do not require regearing. However, if you have a very small engine or tall axle gears, you may notice reduced acceleration and fuel economy. Regearing can restore performance but is not mandatory.
Our Verdict
After our research and comparison, the BFGoodrich All-Terrain T/A KO2 is our top pick for its excellent all-around performance, durability, and long tread life. For those who need maximum off-road traction, the Goodyear Wrangler MT/R with Kevlar is a close runner-up, offering superior mud and rock capability.
