1. Nitto Trail Grappler M/T: Best Overall Mud-Terrain
In our evaluation, the Nitto Trail Grappler M/T stands out as a top mud-terrain choice for 20-inch rims. Its aggressive tread design provides exceptional grip in loose terrain, while the reinforced sidewalls resist cuts and abrasions. Owner feedback consistently praises its durability on rocky trails and its ability to handle deep mud. The tire also performs reasonably well on pavement, though some road hum is present at highway speeds.
However, this tire is not ideal for daily drivers who prioritize cabin quietness. If you spend most of your time on paved roads, an all-terrain may suit you better. The Trail Grappler is best for off-road enthusiasts who need a tough tire for weekend adventures and can tolerate some noise during the week.
- Aggressive tread pattern with stone ejectors for off-road durability
- Reinforced sidewalls for puncture resistance
- Balanced on-road manners for a mud-terrain tire
Pros: Excellent off-road traction in mud and rocks; Good tread life for a mud-terrain
Cons: Noticeable road noise on highway
2. Toyo Open Country M/T: Premium Mud-Terrain
The Toyo Open Country M/T is a premium mud-terrain tire that excels in durability. Its three-ply sidewall construction is among the toughest in its class, making it a favorite for rock crawlers and heavy off-road use. Owner reports indicate excellent resistance to punctures and cuts. On-road, the tire tracks well but transmits more road imperfections than softer compounds.
This tire is not the best choice for those who want a plush highway ride. Its stiffness can be jarring on long trips over rough pavement. We recommend the Toyo M/T for serious off-roaders who demand maximum durability and are willing to sacrifice some on-road comfort.
- Three-ply sidewall for extreme durability
- Deep tread lugs with mud scoops for self-cleaning
- Stable handling at higher speeds
Pros: Exceptional sidewall strength for rock crawling; Long tread life for a mud-terrain
Cons: Stiff ride on rough pavement
3. BFGoodrich All-Terrain T/A KO2: Best All-Terrain
The BFGoodrich All-Terrain T/A KO2 is a legendary all-terrain tire that balances on-road comfort with off-road capability. In our research, it consistently receives high marks for tread life and durability. The CoreGard technology strengthens the sidewall against impacts, and the tire is severe snow rated. It handles gravel, dirt, and light mud well while remaining quiet on the highway.
However, if you regularly tackle deep mud or rock crawling, a mud-terrain tire will outperform the KO2. This tire is ideal for daily drivers who need a capable off-road tire for light to moderate trails and want a comfortable ride for commuting.
- CoreGard technology for sidewall toughness
- Serrated shoulder design for off-road traction
- Mud and snow rated with 3PMSF certification
Pros: Excellent all-around traction on and off road; Long tread life with even wear
Cons: Less aggressive in deep mud than dedicated mud-terrains
4. Mickey Thompson Baja Boss M/T: Best for Off-Road Performance
The Mickey Thompson Baja Boss M/T is engineered for serious off-road performance. Its massive tread blocks and aggressive sidewall lugs provide outstanding grip in loose terrain. Owner feedback highlights its capability in sand and mud, where it digs in and pulls hard. The PowerPly XD sidewall adds significant puncture resistance.
On the flip side, this tire is loud on pavement, with a noticeable drone at highway speeds. It also has a stiffer ride. We recommend the Baja Boss for dedicated off-roaders who prioritize trail performance over on-road civility. If you drive long distances on pavement, consider a quieter all-terrain.
- PowerPly XD sidewall for extreme durability
- Non-directional tread pattern for even wear
- Large tread blocks for maximum traction
Pros: Superb off-road traction in mud and sand; Good self-cleaning ability
Cons: Higher road noise than competitors
5. Cooper Discoverer STT Pro: Best Value Mud-Terrain
The Cooper Discoverer STT Pro offers a solid balance of off-road capability and value. It features a rugged tread design with stone block technology to reduce stone drilling. In owner surveys, it performs well in mud and on rocks, though it may not match the extreme durability of pricier options. The tire is also snow rated for winter use.
However, tread wear tends to be faster, especially on heavy vehicles. If you drive aggressively or carry heavy loads, you may see reduced lifespan. This tire is a good choice for budget-conscious off-roaders who want a capable mud-terrain without the premium price tag.
- Armor-Tek3 construction for strength
- Stone block technology to prevent stone retention
- Mud and snow rated
Pros: Competitive price for a mud-terrain; Good off-road traction
Cons: Tread life is shorter than premium competitors
6. Nitto Ridge Grappler: Best Hybrid Terrain
The Nitto Ridge Grappler is a hybrid tire that aims to bridge the gap between all-terrain and mud-terrain. It offers a more aggressive look than a standard all-terrain but with less noise than a full mud-terrain. In our research, it performs adequately on gravel and dirt roads but struggles in deep mud where larger lugs are needed.
This tire is a compromise that may not satisfy hardcore off-roaders. It is best suited for drivers who want an aggressive appearance and occasional light off-roading without the constant hum of a mud-terrain. If you frequently encounter deep mud or rocks, consider a dedicated mud-terrain instead.
- Hybrid tread pattern combining mud and all-terrain features
- Variable pitch tread for reduced noise
- Reinforced shoulder blocks
Pros: Quieter than many mud-terrains; Decent off-road traction for light to moderate use
Cons: Not as capable in deep mud as full mud-terrains
7. Falken Wildpeak A/T3W: Best All-Weather All-Terrain
The Falken Wildpeak A/T3W is an all-terrain tire with a focus on all-weather performance. It features 3D sipes and a silica compound for grip on snow and ice, earning it the 3PMSF rating. On-road, it rides smoothly and quietly, making it a great choice for daily drivers. Owner feedback highlights its long tread life and even wear.
However, this tire is not intended for serious off-roading. Its tread pattern is mild and will not perform well in mud or on rocky trails. If you need a tire for occasional light off-road use but prioritize snow and wet performance, the Wildpeak is a solid option. For heavy off-roading, look elsewhere.
- 3D sipes for snow and ice traction
- Heat diffuser technology for cooler running
- Deep tread depth for long life
Pros: Excellent snow and wet traction; Smooth and quiet ride
Cons: Less aggressive off-road than mud-terrains
Frequently Asked Questions
Will 36-inch tires fit on 20-inch rims without modifications?
Fitting 36-inch tires on 20-inch rims often requires a lift kit or leveling kit, especially on trucks and SUVs. Clearance issues with the suspension, fenders, and wheel wells are common. We recommend checking your vehicle’s specifications and consulting a professional installer to ensure proper fitment and avoid rubbing.
What is the difference between all-terrain and mud-terrain tires for 20-inch rims?
All-terrain tires offer a balance of on-road comfort and off-road capability, with quieter rides and longer tread life. Mud-terrain tires have deeper, more aggressive tread patterns for superior traction in mud, rocks, and loose terrain, but they are noisier and wear faster on pavement. Your choice depends on how much off-roading you do.
How do I choose the right load range for 36-inch tires?
Load range indicates the tire’s maximum load capacity. For heavy trucks and SUVs, Load Range E (10-ply rating) is common for 36-inch tires. Always match the load range to your vehicle’s weight and towing requirements. Exceeding the load rating can lead to tire failure.
Are 36-inch tires on 20-inch rims legal on public roads?
Legality depends on local regulations. Some states have laws limiting tire height or requiring fender coverage. Additionally, speedometer recalibration is often needed because larger tires affect accuracy. Check your local vehicle codes and ensure your tires are DOT approved.
How do 36-inch tires affect fuel economy and handling?
Larger tires increase rolling resistance and weight, which typically reduces fuel economy. Handling may feel heavier, and braking distances can increase. It is important to maintain proper tire pressure and consider upgrading your vehicle’s suspension to compensate for the added size.
Our Verdict
After evaluating specifications and owner feedback, our top pick is the Nitto Trail Grappler M/T for its excellent off-road traction and durability. For those who need a more road-friendly option, the BFGoodrich All-Terrain T/A KO2 is a strong runner-up, offering a great balance of on-road comfort and light off-road capability.
