Key takeaways
- The dual-service trade-off: A well-chosen all-terrain tire can improve off-road performance without sacrificing on-road comfort, according to Car and Driver. However, aggressive tread designs with larger blocks and wider voids generate increased road noise, reduce dry pavement responsiveness, and add weight and rolling resistance that may slightly lower fuel economy compared to highway all-season tires.
- Construction choices (SL vs. LT): Passenger-rated tires generally offer a smoother ride, while Light Truck (LT) tires feature stronger casings and higher load capacities but may ride more firmly, as reported by Car and Driver.
- Winter and snow certification: An all-season label alone does not guarantee severe winter capability. Tires marked with the three-peak mountain snowflake (3PMSF) symbol indicate compliance with industry severe-snow-service requirements (Car and Driver), while multi-tire winter testing by MotorTrend showed that tread patterns that retain packed snow in the tread face provide better traction than patterns that eject it.
- Operating limits and warranty requirements: Operating tires outside recommended inflation limits carries significant warranty consequences. NEXEN TIRE limited warranty policy explicitly excludes continued use while flat, severely underinflated, or overinflated. Matching or exceeding the vehicle manufacturer's recommended size, load index, and speed rating is required for warranty eligibility.
- Market option highlights: Key choices across the segment—including the NEXEN TIRE ROADIAN ATX, NEXEN TIRE ROADIAN AT Pro RA8, BFGoodrich All-Terrain T/A KO3, Falken Wildpeak A/T4W, and Toyo Open Country A/T III—offer distinct combinations of 3PMSF winter certification, off-road tread designs, and on-road usability for trucks and SUVs.
Balancing daily commuting with unpaved capability
Whether driving a pickup, SUV, or crossover, a well-chosen all-terrain tire can improve off-road performance without sacrificing on-road comfort, according to reporting from Car and Driver. The publication notes that all-terrain tires serve as a practical choice for motorists who regularly navigate a combination of paved highways, gravel corridors, and dirt roads in varied weather conditions.
| Driving Environment | Key Operational Demands | Tire Design Considerations |
|---|---|---|
| Paved Highway & Daily Commute | Cabin acoustic comfort, fuel efficiency, dry and wet pavement responsiveness | Standard void spacing, moderate rolling resistance, compliant casing construction |
| Gravel & Dirt Trails | Grip on loose surfaces, puncture resistance, mechanical durability | Larger tread blocks, wider voids for mechanical bite, robust casing structure |
The fundamental design compromise centers on tread pattern aggressiveness. Aggressive all-terrain tires use larger blocks and wider voids to improve grip on loose surfaces, but Car and Driver notes that these features can create more highway noise and reduce dry-pavement responsiveness. In addition, their added weight and rolling resistance may slightly reduce fuel economy during daily driving.
For vehicles that rarely encounter unpaved gravel, dirt, mud, or snow, Car and Driver notes that dedicated highway all-season tires may deliver better ride comfort, quieter operation, longer tread life, and improved fuel economy. For drivers who frequently encounter unpaved trails alongside daily commutes, selecting an appropriate all-terrain tire provides the needed off-road grip while keeping everyday highway driving manageable.
Gravel roads, unpaved surfaces, and hazard risks
Traversing unpaved surfaces and rough trails subjects tires to hazards that differ from standard paved driving. According to Car and Driver, the right all-terrain tire provides the traction, durability, and control needed to handle rocky trails, muddy forest roads, and daily commutes.
When evaluating tire durability for gravel and unpaved travel, buyers must account for the difference between standard tread wear and excluded road hazard damage. Under the limited warranty terms published by NEXEN TIRE, damage resulting from road hazards—including cuts, splits, punctures, crushing, and impact breaks—is explicitly excluded from warranty coverage. Furthermore, premature or irregular wear caused by vehicle mechanical deficiencies or failure to rotate tires at recommended intervals is also excluded.
To maintain structural condition and preserve warranty coverage across mixed-surface driving, vehicle owners must adhere to routine maintenance practices:
- Regular pressure verification: Ensuring tires remain inflated to the vehicle manufacturer's recommended cold pressure prevents abnormal wear and overheating.
- Systematic rotation: Rotating tires and checking wheel alignment every 10,000 km (6,000 miles) fulfills owner obligations and helps equalize tread wear across all positions.
- Alignment checks: Promptly rectifying suspension misalignment avoids rapid, irregular tread scrub.
Trail driving and inflation limits
Adjusting tire operating conditions on unpaved terrain requires strict attention to pressure limits and manufacturer guidelines.
Operating tires outside prescribed inflation levels carries significant warranty and safety implications:
- Underinflation exclusions: NEXEN TIRE limited warranty terms state that continued use while flat, severely underinflated, or overinflated is explicitly excluded from warranty protection.
- Road hazard damage: Damage resulting from cuts, splits, punctures, crushing, and impact breaks is not covered under the NEXEN TIRE limited warranty.
- Proper pressure maintenance: Tires operated on trail surfaces must be maintained within approved inflation parameters and reinflated to vehicle manufacturer specifications before resuming highway travel.
Winter capability: 3PMSF certification vs. all-season designations
According to Car and Driver, the right all-terrain tire provides the traction, durability, and control needed to handle snow-covered passes and daily commutes with confidence. However, tire buyers should not assume that every all-terrain model delivers identical winter grip.
For drivers who regularly encounter snow, Car and Driver advises looking specifically for the three-peak mountain snowflake (3PMSF) symbol, noting that it indicates the tire has met industry severe-snow-service performance requirements, whereas an all-season label alone does not guarantee equivalent winter traction. All-terrain options such as the NEXEN TIRE ROADIAN ATX and ROADIAN AT Pro RA8 carry 3PMSF certification, meeting severe snow service standards while maintaining daily driving and off-road capability.
Multi-season field testing conducted by MotorTrend evaluated 11 tire models in winter conditions over a three-year period involving normal daily driving and adventure scenarios on highways, around town, and on trails in snow ranging from a couple inches to a few feet. Testing evaluated acceleration, braking, and handling, with the publication noting that there were no overall rankings or winners, yielding several key observations:
- Snow retention in tread: From comparing tread types, MotorTrend reported that tires that keep snow packed into the tread face provide better traction than those that eject it.
- Toyo Open Country A/T III evaluation: MotorTrend reported that the Toyo Open Country A/T III earned its 3PMSF rating, comporting itself predictably in every winter situation from highways and trails piled with deep snow to slow-speed maneuvering on moderately packed slush, demonstrating commendable snow performance and off-road capability.
- Dedicated snow tires: MotorTrend noted that dedicated snow tires cannot be beaten for snow traction.
Carcass construction: Passenger-rated vs. Light Truck (LT)
When deciding which all-terrain tire is right, drivers must evaluate how and where they drive most, including selecting appropriate casing constructions and load ratings.
| Specification Dimension | Passenger-Rated Tires | LT-Rated Tires |
|---|---|---|
| On-Road Ride Quality | Generally offer a smoother ride | May ride more firmly |
| Casing and Capacity | Standard casing construction | Stronger casings and higher load capacities |
According to Car and Driver, passenger-rated tires generally offer a smoother ride, while LT-rated tires feature stronger casings and higher load capacities but may ride more firmly. Car and Driver emphasizes that drivers should always match the replacement tire's load index and speed rating to vehicle requirements.
When selecting replacement tires, matching the vehicle manufacturer's baseline specifications is an essential requirement. NEXEN TIRE warranty criteria require that the replacement tire's size, load-carrying class, and speed class be equal to or greater than those recommended by the original vehicle manufacturer. Installing an incorrect tire size, load index, or speed symbol invalidates limited warranty coverage.

Frequently asked questions
How do all-terrain tires affect fuel economy compared to highway tires?
According to Car and Driver, highway all-season tires may deliver improved fuel economy if your vehicle rarely encounters gravel, dirt, mud, or snow. Aggressive all-terrain tires feature larger blocks and wider voids to improve grip on loose surfaces, and their added weight and rolling resistance may slightly reduce fuel economy.
What is the practical difference between an all-season tire and a 3PMSF-certified tire?
According to Car and Driver, the three-peak mountain snowflake (3PMSF) symbol indicates that a tire has met the industry's severe-snow-service performance requirements. An all-season label alone does not guarantee equivalent winter traction in severe snow conditions.
Should I choose passenger-rated or LT-rated tires?
According to Car and Driver, passenger-rated tires generally offer a smoother ride, while LT-rated tires feature stronger casings and higher load capacities but may ride more firmly. When choosing replacement tires, always ensure the tire size, load-carrying class, and speed class meet or exceed the recommendations of the vehicle manufacturer, as installing an incorrect load index or speed symbol is excluded from warranty coverage under NEXEN TIRE policy.
What are the risks of operating tires at improper pressures?
Operating tires in a flat or severely underinflated state stresses internal tire structure and voids standard warranty protections. Under NEXEN TIRE's limited warranty policy, continued use while flat or severely underinflated or overinflated is explicitly excluded from coverage. Tires must be maintained at recommended inflation pressures for safe highway operation.
How often should tires be rotated on an overlanding vehicle?
Under NEXEN TIRE limited warranty terms, owners are required to rotate tires at the proper air pressure and check wheel alignment every 10,000 km (6,000 miles). Failing to rotate tires at recommended intervals or experiencing irregular wear caused by mechanical vehicle deficiencies results in exclusion from limited warranty coverage.
