1. BFGoodrich All-Terrain T/A KO2: Best Overall All-Terrain
In our evaluation, the BFGoodrich All-Terrain T/A KO2 stands out as the most capable all-terrain tire for the AT4. Its 3-ply sidewall resists cuts and punctures, making it ideal for off-road trails. Owner feedback consistently praises its longevity and traction on loose surfaces. Based on the spec sheets, it meets severe snow service requirements, providing confidence in winter conditions.
However, the rugged construction adds weight that can reduce fuel economy slightly. If you primarily drive on pavement and rarely venture off-road, a lighter all-terrain or highway tire may serve you better. This tire is best for owners who prioritize off-road capability and durability above all else.
- Excellent off-road traction with tough sidewall for rocky terrain
- Serpentine design reduces stone retention in tread
- Long tread life with 50,000 mile warranty (varies by size)
Pros: Exceptional durability for off-road abuse; Strong snow and ice performance
Cons: Heavier than some competitors, slight fuel economy hit
2. Michelin Defender LTX M/S2: Best Highway All-Season
The Michelin Defender LTX M/S2 is the top pick for AT4 owners who spend most of their time on paved roads. We compared its wet braking data from industry tests and found it consistently outperforms competitors. Owner feedback highlights its quiet ride and long tread life, making it a cost-effective choice for daily driving and towing.
Its weakness is off-road capability; it is not designed for mud or rocky trails. If you frequently take your AT4 off the beaten path, consider a more aggressive tire. This tire is ideal for highway commuters and those who prioritize comfort and longevity over extreme traction.
- Superior wet and dry braking performance
- Comfortable, quiet ride on highways
- Excellent tread life for long-term value
Pros: Longest treadwear warranty in its class; Great fuel efficiency due to low rolling resistance
Cons: Limited off-road traction compared to all-terrains
3. Nitto Ridge Grappler: Best Hybrid Terrain
The Nitto Ridge Grappler bridges the gap between mud-terrain and all-terrain tires. Our research shows it offers strong off-road grip while maintaining acceptable road manners. Owner feedback indicates it performs well in snow and light mud, and the hybrid design keeps noise lower than full mud-terrains.
However, its tread life is not as long as the Michelin Defender, and it can be pricier per mile. If you rarely go off-road, you might be better served by a highway tire. This tire suits AT4 owners who want a capable off-road tire they can live with daily.
- Balances off-road traction with on-road comfort
- Unique tread design reduces road noise
- Good self-cleaning in mud and snow
Pros: Versatile performance for mixed driving; Aggressive look without excessive noise
Cons: Tread life shorter than dedicated highway tires
4. Goodyear Wrangler Duratrac: Best for Snow and Ice
The Goodyear Wrangler Duratrac is a favorite among AT4 owners in snowy regions. Based on owner feedback and industry snow traction tests, it delivers impressive grip on ice and packed snow. Its Tractive Groove technology helps evacuate slush, and the rugged sidewall adds protection on rocky trails.
On the downside, the aggressive tread pattern generates more road noise on pavement, which some drivers find intrusive. If you live in a mild climate, a quieter all-terrain may be a better choice. This tire is best for those who face harsh winters and need reliable snow performance.
- Excellent snow and ice traction with Tractive Groove
- Durable sidewall for off-road protection
- Good tread life for a winter-rated tire
Pros: Top-tier winter performance; Versatile for off-road use
Cons: Road noise higher than some competitors
5. Toyo Open Country A/T III: Best Balanced All-Terrain
The Toyo Open Country A/T III offers a well-rounded package for the GMC AT4. Our evaluation of its spec sheet shows it combines a 3-ply sidewall for off-road durability with a tread pattern designed for low noise. Owner feedback often highlights its smooth highway ride and reliable traction in various conditions.
However, it may not satisfy hardcore off-roaders who need maximum mud grip. If you frequently tackle deep mud, a mud-terrain tire would be more appropriate. This tire is ideal for AT4 owners who want a capable all-terrain that doesn’t compromise daily comfort.
- Excellent off-road traction with 3-ply sidewall
- Quiet and comfortable on highway
- Good tread life warranty
Pros: Balanced on- and off-road performance; Strong sidewall protection
Cons: Less aggressive than dedicated mud-terrains
6. Falken Wildpeak A/T3W: Best Value All-Terrain
The Falken Wildpeak A/T3W is a strong contender for budget-conscious AT4 owners. We compared its features against higher-priced tires and found it offers good snow and wet traction thanks to its 3D Canyon Sipes. Owner feedback appreciates its value, noting it performs well in light off-road conditions.
However, its tread life is shorter than the Michelin Defender or BFGoodrich KO2, and it may not withstand heavy off-road abuse. If you demand maximum durability or longevity, you might prefer a premium tire. This tire is best for those who want a capable all-terrain at a lower cost.
- Good snow and wet traction for the price
- Durable construction with heat diffuser technology
- Attractive price point compared to premium brands
Pros: Affordable without sacrificing key features; Decent off-road capability for light trails
Cons: Tread life not as long as premium competitors
7. Cooper Discoverer AT3 4S: Best for Towing and Hauling
The Cooper Discoverer AT3 4S is tailored for AT4 owners who frequently tow or haul heavy loads. Our research indicates its reinforced casing provides stability under weight, and its severe snow rating ensures traction in winter. Owner feedback from those who tow confirms it handles well with a trailer attached.
However, the stiff sidewall can make the ride feel harsher on rough roads, and on-road noise is higher than some all-terrains. If you rarely tow, a more comfort-oriented tire may be a better fit. This tire is specifically for those who need a tire that can handle heavy loads without compromising snow capability.
- Stable handling under heavy loads
- Good snow traction with severe snow rating
- Reinforced construction for towing
Pros: Excellent stability when towing; Reasonable tread life for a heavy-duty tire
Cons: Ride comfort less refined than competitors
Frequently Asked Questions
What tire size fits the GMC AT4?
The GMC AT4 typically comes in sizes like 275/60R20 or 275/65R18, but always check your specific model year’s door jamb sticker. We recommend consulting your owner’s manual or a tire professional to confirm the correct size and load rating.
Can I use all-terrain tires on the AT4 year-round?
Yes, many all-terrain tires like the BFGoodrich KO2 or Toyo A/T III are severe snow rated and can be used year-round. However, if you face extreme winter conditions, a dedicated winter tire may offer better ice traction. For most climates, a good all-terrain suffices.
How often should I rotate tires on my AT4?
We recommend rotating your tires every 5,000 to 7,000 miles to ensure even wear. This is especially important for the AT4 due to its weight and potential off-road use. Check your tire manufacturer’s guidelines for specific intervals.
Do I need load range E tires for the AT4?
Load range E tires have a higher weight capacity, which is beneficial if you frequently tow or carry heavy loads. If you mostly drive unloaded, load range C or D may be sufficient and offer a smoother ride. Refer to your vehicle’s GVWR and tire placard.
What is the best tire for off-road performance on the AT4?
For serious off-roading, the BFGoodrich All-Terrain T/A KO2 or Nitto Ridge Grappler are top choices. The KO2 offers superior sidewall protection, while the Ridge Grappler provides a good balance of off-road grip and on-road comfort. Choose based on your specific terrain.
Our Verdict
After researching and comparing specifications, industry standards, and owner feedback, our top pick for most GMC AT4 owners is the BFGoodrich All-Terrain T/A KO2 for its exceptional off-road durability and all-season capability. If you prioritize highway comfort and tread life, the Michelin Defender LTX M/S2 is an excellent runner up.
