All-terrain tires sit right in the middle of the off-road tire world. They are built to handle a wide variety of surfaces while still delivering acceptable on-road manners. According to BFGoodrich’s 4×4 driving guide, their less aggressive tread design offers better highway comfort, quieter ride quality and improved on-road handling compared to mud-terrain options, yet they remain capable on moderate trails. NHTSA describes all-terrain tires as mainly used on four-wheel drive vehicles and says they provide a good compromise between on-road driving and off-road capability.
What makes an all-terrain tire different
BFGoodrich’s tire selection guide explains that all-terrain tires are designed to work across many surfaces. The tread pattern is less aggressive than a mud-terrain tire, which translates into a quieter ride, and better on-road handling. At the same time, the tread is still open enough to find grip on gravel, dirt, hard-packed trails and light mud.
This balance makes all-terrain tires a popular pick for several real-world uses. BFGoodrich lists long-distance overlanding and expedition driving, mixing trail time with highway commuting, 4×4 trucks used for towing or daily work, and winter driving conditions where traction matters as situations where all-terrain tires shine. The key is that the tire is not optimized for a single extreme; it is designed to be competent in many.
All-terrain versus mud-terrain: choosing based on use, not looks
One of the most important decisions an off-road driver makes is whether to run an all-terrain or a mud-terrain tire. BFGoodrich’s guide is direct: performance should come before appearance. Mud-terrain tires use large tread blocks and wide voids that eject mud, sand and soft soil while biting into uneven surfaces like rocks and ruts. That aggressive design, however, comes with trade-offs. BFGoodrich says mud-terrain tires are not quiet or fuel-efficient, a trade-off worth making mainly if you spend more time on the trail than the road.
All-terrain tires, by contrast, are built for drivers who spend more miles on pavement than in deep mud. BFGoodrich advises being honest about where you actually drive. If most of your time is on highways with occasional trail use, an all-terrain tire is the better fit, even if a mud-terrain looks tougher. For those who spend real time in deep mud, rock crawling and committed off-camber terrain, mud-terrain tires earn their compromises. For a deeper look at that category, see our Mud-Terrain Tires guide.
Sizing, load ratings and the P-metric warning
Moving to a larger tire changes more than just the look of the vehicle. BFGoodrich’s tire selection guide stresses that larger-than-stock tires often require aftermarket modifications such as a lift kit, and those changes can affect brake lines, steering geometry and suspension components. All of those alterations can influence handling and may increase rollover risk, particularly on side hills and during emergency maneuvers on pavement.
Most off-road tires fall into one of two sizing systems: LT-metric or high-flotation. LT-metric tires are engineered for light trucks and are stronger and more durable than passenger tires, built to handle towing, hauling and off-road use. High-flotation tires offer similar performance but use a different sizing format and are popular for drivers who want a larger footprint without diving into load charts. BFGoodrich warns never to replace original LT tires with P-metric (passenger) tires, because you will lose critical load capacity and durability. If a vehicle came from the factory with P-metric tires, the guide suggests replacing them before heading off-road, as they are not built for those demands.
When you change tire size, the vehicle manufacturer’s recommended pressures, found on the door placard and in the owner’s manual, no longer apply. BFGoodrich says larger tires typically require less pressure to carry the same load and recommends consulting a tire professional to calculate the correct pressure for the upgraded setup. NHTSA also directs drivers to check the Tire and Loading Information Label on the driver’s side door edge or post for the correct size and pressure for the original equipment, and to consult the owner’s manual.

Tire pressure: on-road safety and off-road traction
Proper inflation pressure is the single most important tire condition to monitor. The U.S. Tire Manufacturers Association (USTMA) states that correct pressure gives tires the ability to support the vehicle and allows the driver to control it for maximum performance, while also maximizing fuel economy. Underinflated tires generate excessive heat and stress, causing irregular wear and internal damage. Overinflated tires are more prone to cuts, punctures or impact damage from potholes.
For on-road driving, BFGoodrich’s guide says to follow the vehicle manufacturer’s recommended PSI for both front and rear tires if you are running original equipment tires. That number is on the tire placard, typically inside the driver’s door, and in the owner’s manual. NHTSA echoes this: the correct pressure is what the vehicle manufacturer has listed, not the maximum pressure molded on the tire sidewall. Both NHTSA and USTMA recommend checking pressure at least once a month when the tires are cold, meaning the vehicle has not been driven for at least three hours. USTMA adds that inflation pressure changes roughly one to two pounds for every 10 degrees of temperature change, so seasonal checks are important.
If you have upgraded from P-metric to LT-metric or high-flotation tires, BFGoodrich cautions that the old placard numbers no longer apply. You need the tire manufacturer’s pressure recommendation for that specific size and use case. Getting this right ensures safe handling and full tread life when you return to paved roads. A reliable pressure gauge and portable air compressor are essential gear; see our Tire Pressure Equipment page for what to carry.
Airing down: the free traction upgrade
Lowering tire pressure before hitting the trail, known as airing down, is one of the most effective off-road techniques. BFGoodrich explains that it increases the tire’s footprint, improving traction on soft or uneven terrain and creating a smoother ride over bumps and rocks. There is no universal air-down pressure; the right number depends on tire type, terrain and vehicle weight. The guide recommends that new off-roaders talk to an experienced driver before airing down for the first time.
Temperature plays a role, too. BFGoodrich notes that cold mornings mean lower pressure, while hot days or direct sun raise pressure. Always check PSI before you hit the trail, not after the tires have warmed up. Going too low can unseat the tire bead from the rim and cause serious damage; beadlock wheels can help prevent that if you air down frequently or to very low levels. Critically, tires that have been aired down for off-road use must be reinflated before driving on paved roads. Underinflated tires on the highway reduce handling, accelerate uneven treadwear and run hotter, increasing the risk of a blowout. BFGoodrich’s guide is clear: never head off-road without a way to air back up.
Tread depth, rotation and alignment: the maintenance trio
USTMA and NHTSA both stress that tread depth is directly tied to safety. Tires must be replaced when the tread wears down to 2/32 of an inch. USTMA describes built-in tread wear indicators, or wear bars, that sit between the tread grooves; when the tops of those bars are flush with the tread surface, the tire needs to be replaced. NHTSA offers the penny test: place a penny upside down in a tread groove; if you can see the top of Lincoln’s head, the tread is too shallow.
NHTSA says that, if recommended by the vehicle manufacturer, you should rotate tires every 5,000 to 8,000 miles or sooner if uneven wear appears, and adds that some vehicles with different front and rear tire sizes cannot be rotated; always check the owner’s manual. After rotation, inflation pressure should be set to the vehicle manufacturer’s specifications.
NHTSA adds that having your tires balanced and a wheel alignment performed by a qualified technician is important for the safety of your vehicle and to maximize tire life. For a full pre-trip routine that includes tire checks, visit our Pre-Trip Inspections guide.
All-terrain tires in winter conditions
BFGoodrich lists winter driving conditions where traction matters among the uses for all-terrain tires, and its terrain guide says all-terrains tend to perform well on snowy roads thanks to their tighter tread and increased siping. For winter confidence it points to the Three-Peak Mountain Snowflake (3PMSF) symbol, which BFGoodrich says means the tire meets or exceeds the minimum requirements to be classified as winter-rated. NHTSA notes that winter tires are more effective than all-season tires in deep snow. If you regularly face harsh winter roads, check for the 3PMSF symbol or consider dedicated winter tires. The broader Tires and Suspension section has more.
Frequently asked questions
Can I use all-terrain tires as my only set year-round?
Yes, for many drivers they are a year-round solution. BFGoodrich’s guide lists winter driving conditions as one of the uses where all-terrain tires perform well, and NHTSA describes them as a compromise between on-road driving and off-road capability. However, if you regularly encounter deep snow or ice, a dedicated winter tire will provide more grip. Always match the tire to the conditions you actually face.
Do I need to change tire pressure when I switch from highway to trail?
Yes. BFGoodrich explains that airing down increases the tire’s footprint for better off-road traction and a smoother ride. Once you return to pavement, you must reinflate to the vehicle manufacturer’s recommended pressure. Driving on the road with underinflated tires reduces handling, accelerates wear and raises the risk of a blowout.
How do I know if my all-terrain tires are worn out?
USTMA and NHTSA both say tires should be replaced when the tread reaches 2/32 of an inch. You can check this with the built-in wear bars or the penny test. If the tread is flush with the wear bars, or if Lincoln’s head is fully visible when a penny is inserted upside down, it is time for new tires.
