1. BFGoodrich All-Terrain T/A KO2: Best Overall
The BFGoodrich All-Terrain T/A KO2 is a benchmark in the 37 inch all terrain category. Based on manufacturer specs and extensive owner feedback, its 3-ply sidewall provides exceptional resistance to cuts and abrasions, making it a favorite for rocky trails. The tread pattern is designed to eject mud and stones, maintaining traction in loose conditions. On pavement, the KO2 delivers stable handling and reasonable road noise for a tire of this size.
However, the KO2’s robust construction adds weight, which can slightly reduce fuel efficiency and acceleration. For daily drivers who prioritize off-road toughness over on-road lightness, this is a top pick. If you mostly drive on pavement and want a lighter tire, consider a more highway-oriented all-terrain.
- CoreGard technology for enhanced sidewall toughness
- Mud-phobic bars shed debris for better traction
- Serrated shoulder design for off-road grip
Pros: Excellent durability and puncture resistance; Balanced on-road comfort and off-road capability
Cons: Heavier than some competitors, can affect fuel economy
2. Nitto Ridge Grappler: Best Hybrid
The Nitto Ridge Grappler is a hybrid all-terrain that bridges the gap between AT and MT. Our research shows its staggered shoulder lugs provide excellent traction in mud and loose dirt, while the center tread maintains stability on highways. Owner feedback highlights its relatively low noise for an aggressive tire, thanks to the variable pitch pattern. The stone ejectors help prevent debris from getting lodged in the tread.
While the Ridge Grappler performs well off-road, its tread life is not as long as some dedicated ATs under constant highway driving. If you spend most of your time on pavement with occasional off-road trips, this tire is a strong choice. For extreme rock crawling or heavy towing, a more rugged option may be better.
- Hybrid tread design combines AT and MT features
- Stone ejectors prevent stone drilling
- Variable pitch tread reduces road noise
Pros: Aggressive off-road look with quieter ride than a mud tire; Good balance of on-road comfort and off-road traction
Cons: Tread life may be shorter than traditional ATs in heavy use
3. Toyo Open Country A/T III: Best for Longevity
The Toyo Open Country A/T III is designed for long mileage and on-road comfort. According to manufacturer specs, its tread compound and deep grooves promote even wear, and the 50,000 mile warranty reflects confidence in durability. Owner reviews consistently praise its quiet ride and stable handling on pavement. The stone resistance pockets help prevent punctures on gravel roads.
However, this tire’s all-terrain capability is more moderate than the KO2 or Ridge Grappler. In thick mud or loose sand, it may struggle to self-clean. If your driving is mostly highway with light off-road use, the A/T III is an excellent value. For serious off-roaders, a more aggressive tire is recommended.
- Silent Wall technology reduces road noise
- Stone resistance pocket for fewer punctures
- Deep tread depth for long wear
Pros: Excellent tread life backed by warranty; Quiet and comfortable on highways
Cons: Not as aggressive in deep mud as some competitors
4. Cooper Discoverer AT3 XLT: Best Value
The Cooper Discoverer AT3 XLT offers a strong balance of capability and affordability. Our evaluation of owner feedback shows it performs well in snow and rain, with the 3-peak mountain snowflake rating for severe winter conditions. The dual compound tread helps extend tread life, and the Whisper Grooves keep noise levels down. It’s a solid choice for budget-conscious buyers who still want reliable all-terrain performance.
However, the sidewall construction is not as tough as the KO2 or Toyo. For frequent rock crawling or sharp trail debris, it may be more prone to cuts. If your off-roading is moderate and you want to save money, the AT3 XLT is a great pick. For extreme conditions, consider a tire with a stronger sidewall.
- Dual compound tread for long wear and traction
- Whisper Grooves reduce road noise
- Mud and snow rated with 3-peak mountain snowflake
Pros: Competitive price for the features offered; Good snow and wet traction
Cons: Sidewall less robust than premium competitors
5. Falken Wildpeak A/T3W: Best for Wet Conditions
The Falken Wildpeak A/T3W is engineered for wet weather performance. Based on manufacturer data, its 3D sipes and silica-infused compound provide strong grip on rain-soaked roads. Owner feedback also notes good snow traction. The heat diffuser technology helps prevent heat buildup during long highway drives, which can extend tire life.
However, in dry off-road conditions, the tread pattern is less aggressive than some ATs. Tread life reports are mixed, with some owners experiencing faster wear on heavy vehicles. If you frequently drive in rain or light snow, this tire is a smart choice. For dry, rocky trails, look elsewhere.
- 3D Canyon Sipe technology for wet traction
- Heat diffuser technology reduces heat buildup
- Deep tread with stone ejectors
Pros: Exceptional hydroplaning resistance; Durable construction for light off-roading
Cons: Tread life may be less than some competitors
6. General Grabber A/TX: Best for Heavy Loads
The General Grabber A/TX is built for heavy-duty applications. With a Load Range F and 10-ply rating, it can handle significant weight, making it ideal for trucks that tow or carry heavy loads. The sidewall traction ridges add grip when aired down on trails. Owner feedback indicates decent off-road performance for a tire in this load class.
However, the stiff construction results in a firmer ride on pavement, and road noise is more noticeable than lighter ATs. For daily driving without heavy loads, this tire may feel harsh. If you frequently tow or haul, the Grabber A/TX is a dependable choice. For a smoother ride, consider a Load Range E tire.
- Load Range F for heavy towing and hauling
- Traction ridges on sidewall for extra grip
- Sound dampening technology for quieter ride
Pros: Very high load capacity; Good off-road traction for a heavy-duty tire
Cons: Stiff ride on pavement due to high ply rating
7. Mickey Thompson Baja Boss A/T: Best for Off-Road
The Mickey Thompson Baja Boss A/T is designed for serious off-road use. Its aggressive tread pattern and PowerPly sidewall provide outstanding grip in mud, rocks, and sand. Owner feedback highlights its ability to self-clean and maintain traction in challenging conditions. The tire is also capable on pavement, but with a trade-off.
On-road, the Baja Boss A/T is noticeably noisier than other ATs, and tread life is shorter due to the soft compound. It is not ideal for daily highway commutes. If your driving is predominantly off-road and you prioritize traction over comfort, this tire delivers. For mixed use, a more balanced AT is better.
- PowerPly sidewall for extreme off-road resistance
- Large tread blocks for aggressive traction
- Variable pitch tread for noise reduction
Pros: Excellent off-road traction in mud and rocks; Tough sidewall for trail protection
Cons: Noisy on highway and lower tread life
Frequently Asked Questions
What is the difference between an all-terrain tire and a mud-terrain tire?
All-terrain tires are designed for a balance of on-road comfort and off-road capability. They have less aggressive tread patterns, lower noise, and longer tread life than mud-terrain tires, which prioritize off-road traction in deep mud and rocks at the expense of highway comfort and noise.
Can I use 37 inch all-terrain tires on my stock truck?
In most cases, 37 inch tires require a lift kit and wheel offset adjustments to fit without rubbing. We recommend checking your vehicle’s clearance and consulting a professional before installation. Some trucks like the Ford Raptor may accept 37s with minimal modifications.
How long do 37 inch all-terrain tires typically last?
Tread life varies by brand, driving habits, and vehicle weight. On average, 37 inch AT tires can last between 40,000 and 60,000 miles. Tires with harder compounds and deeper tread, like the Toyo Open Country A/T III, tend to last longer.
Are 37 inch all-terrain tires good for snow?
Many all-terrain tires have the 3-Peak Mountain Snowflake rating, indicating they perform in severe snow conditions. Tires like the Cooper Discoverer AT3 XLT and Falken Wildpeak A/T3W are good choices for snow. However, dedicated winter tires offer better ice traction.
What load range should I choose for my 37 inch AT tires?
Load Range E is common for 37 inch tires and suits most light trucks and SUVs. For heavy towing or hauling, Load Range F offers higher capacity but a stiffer ride. Always match the load range to your vehicle’s weight requirements.
