All-Terrain Tires vs All-Season Tires: Key Differences and Which to Buy
All-season tires are built for paved roads in changing weather. All-terrain tires are built for changing ground.
An all-season tire gives you a quiet ride, long tread life and steady grip on dry roads, wet roads and light snow.
An all-terrain tire adds a deeper, more open tread and tougher sidewalls. That lets it grip gravel, dirt, sand and light mud too, but you give up some quietness, ride comfort and fuel economy.
The short answer: if nearly all your miles are on pavement, go all-season. If you leave the pavement regularly, work on job sites or live down a dirt road, go all-terrain.
One thing most comparisons skip: "all-season" describes weather, and "all-terrain" describes ground. They aren't opposites, and plenty of tires are both. That changes how you should shop, so we'll get to it below.
All-Terrain vs All-Season Tires at a Glance

| Sidewalls | Standard | Usually reinforced against cuts and punctures |
| Road noise | Low | Moderate, more noticeable as they wear |
| Ride comfort | Smoother | Firmer |
| Fuel economy | Better | Slightly lower |
| Wet pavement | Very good | Good |
| Snow | Varies by model; check for 3PMSF | Varies by model; check for 3PMSF |
| Off-road | Weak beyond graded dirt roads | Strong on most unpaved surfaces |
| Price | Lower | Higher at a similar size and load range |
| Best for | Commuting, highway miles, towing on pavement | Mixed use, job sites, rural roads, light trails |
What Are All-Season Tires?
An all-season tire is a road tire designed to work through spring, summer, fall and mild winter conditions. It's the default tire on most cars, SUVs and a lot of pickups.
The tread is built for pavement. Closely spaced blocks or ribs keep more rubber on the road, while grooves and thin slits called sipes push water out of the way.
The rubber compound is a middle-ground recipe. It stays usable across a wide temperature range instead of excelling at one extreme.
Most all-season tires carry an M+S (mud and snow) marking. Don't read too much into it. The M+S designation is based on tread geometry, not on a snow performance test.
Where all-seasons fall short is anything past light snow or a well-kept dirt road. Michelin itself says its Defender LTX M/S2 all-season truck tire is not a dedicated winter tire and points heavy-snow drivers to a winter tire instead.
On pickups, all-season tires usually come as highway (H/T) tires: on-road tread patterns rated for year-round use.
Best for: daily commuting, highway miles, road trips and towing on pavement.
What Are All-Terrain Tires?
An all-terrain (A/T) tire is a dual-purpose tire that drives well on pavement and grips on unpaved ground. In aggressiveness, it sits between a highway tire and a mud-terrain tire.
The tread uses bigger blocks separated by wider voids. On loose ground, block edges dig in, then flex and throw mud and small stones back out, so the tread keeps biting.
Many A/T tires also add stone ejectors in the grooves and tougher sidewall rubber that resists cuts, bruises and punctures. A lot of them come in LT (light truck) construction with higher load ranges.
The trade-off: a heavier, more open design is louder on pavement, rides firmer and takes a little more energy to roll.
Best for: gravel and dirt roads, job sites, ranch and farm work, boat ramps, light trails, and drivers who want one tire for everything.

"All-Season" and "All-Terrain" Aren't Opposites
This is where a lot of buyers get tripped up. The two labels answer different questions:
- All-season answers: what weather is this tire built for?
- All-terrain answers: what ground is this tire built for?
So an all-terrain tire can be rated for year-round use too. Many carry the M+S marking, and a growing number carry the stronger three-peak mountain snowflake (3PMSF) symbol.
A real example: BFGoodrich lists its All-Terrain T/A KO3 as an all-weather, severe-snow-rated tire. That's an all-terrain tire carrying a snow rating many basic all-season tires don't have.
So the useful question usually isn't "all-terrain or all-season?" It's two separate ones:
- How much off-pavement grip and toughness do I actually need?
- What snow rating do my winters call for?
Answer those two, and the right tire gets much easier to pick.
Key Differences Between All-Terrain and All-Season Tires
Traction on gravel, dirt and mud
All-terrain tires win this one clearly. A road tire's narrow grooves fill with dirt and stay filled, so the tread behaves like a slick on loose ground.
An A/T tire's wide voids clear themselves as the tire rolls, which keeps fresh edges biting. All-seasons are fine on a graded gravel road at sensible speed. Ruts, washboard, wet clay or sharp rock are a different story.
Grip on wet pavement
All-season tires usually have the edge on wet roads. More sipes and more continuous rubber give them more biting edges and better water clearing across the footprint.
That matters most at highway speed, where the risk of hydroplaning climbs. Modern A/T tires have narrowed the gap, and once any tire wears down, tread depth matters more than category.
Snow and ice
Neither category name tells you how a tire handles snow. The symbol on the sidewall does.
The 3PMSF symbol means the tire passed a standardized traction test on packed snow. To earn it, a tire must score at least 110 against a reference tire rated 100. M+S alone involves no such test.
In deep, loose snow, an A/T tire's open voids tend to help because they pack with snow and grip it. On packed snow and ice, dense siping and softer compounds matter more.
Neither type replaces a true winter tire on ice. Our guide to the 3PMSF symbol explains what the test does and doesn't measure, and we cover how all-terrain tires really perform in snow separately.
Road noise and ride comfort
All-season tires are quieter. A/T tread blocks strike the pavement one at a time, and the wide voids trap and release air as they roll. Both create that familiar hum.
Stiffer sidewalls and heavier construction also send more small bumps into the cab. Today's A/T tires are far quieter than older designs, but the noise usually grows as the tread wears.
Fuel economy
All-season tires generally roll easier. They're lighter, and their tighter tread flexes less as it rolls, which wastes less energy.
The difference is real but modest. The National Academies found that cutting rolling resistance by 10% improves fuel economy by about 1 to 2%. Expect a small MPG drop with A/T tires, not a dramatic one. Bigger, heavier A/T sizes widen it.
Tread life and warranty
The usual rule says all-season tires last much longer. On passenger-car sizes, that's often true. On light-truck sizes, the gap can be smaller than you'd expect.
Michelin backs the Defender LTX M/S2 with a 50,000- to 75,000-mile warranty, depending on size. BFGoodrich backs the KO3 all-terrain with 50,000 miles. Compare the warranty for the exact size you'd run, not the headline number.
On LT truck tires, you also can't lean on a UTQG treadwear grade. Federal UTQG grading covers passenger car tires, and both Michelin and BFGoodrich note it doesn't apply to their light-truck sizes.
How you drive matters too. Hot, loaded highway miles wear any tire faster, while an all-season tread can chip and chunk quickly on sharp gravel. Our guide to tire treadwear ratings explains what the numbers can and can't tell you.
Price
All-terrain tires usually cost more at a similar size and load range. You're paying for more rubber, deeper tread and reinforced construction. On a truck that runs six tires, that per-tire difference gets multiplied.
All-Terrain or All-Season: Which Should You Choose?
Base the choice on how you actually drove over the last 12 months, not the one trip you're planning.
| How you drive | Best fit |
|---|---|
| Almost all pavement, mild winters | All-season tires from our truck tire range |
| Almost all pavement, real snowy winters | All-weather tires with the 3PMSF symbol |
| Regular gravel, dirt roads or job sites | All-terrain tires |
| Off-pavement work plus snowy winters | A 3PMSF-rated all-terrain tire |
| Months of ice and heavy snow | Dedicated winter tires for the season |
| Deep mud or rock as a routine | Mud-terrain tires |
| Mostly road, but you want a rugged look | A milder A/T or a rugged-terrain tire |
A good gut check: if you can't remember the last time you needed more grip than a gravel driveway, you're paying for capability you won't use.

What Changes for Heavy-Duty and Dually Trucks
On a 3500-series pickup or a dual rear wheel truck, the numbers on the sidewall matter more than the category name.
- Load range comes first. Whatever tread you choose has to carry your axle ratings at the pressure on your door placard. Our guide to reading tire numbers shows where to find it.
- Use the dual load number. LT tires list two load indexes, such as 121/118. The second, lower number applies when tires run in pairs on a dually.
- You're buying six tires. Every per-tire difference in price, wear and rolling resistance gets multiplied by six.
- Watch the gap between the duals. Aggressive A/T tread can trap stones and mud between the inner and outer rear tires, so check there often.
- 19.5-inch wheels play by different rules. Trucks on 19.5s, like the F-450 and F-550 class, mostly run commercial highway and traction treads rather than typical A/T or all-season tires.
We go deeper on dual load ratings, debris between the duals and size options in our all-terrain vs highway tires guide for dually owners.
Safety note: never fit a tire whose load rating, including its dual rating on the rear, is below what your truck requires. If you're changing tire size, have a qualified tire professional confirm fitment first.
Frequently Asked Questions
Can I use all-terrain tires all year round?
Yes. All-terrain tires are designed for year-round use, and many carry the 3PMSF symbol for severe snow. The exception is long, icy winters, where a dedicated winter tire still grips better.
Are all-terrain tires good for daily driving?
Yes, for most drivers. Modern A/T tires are far more road-friendly than older designs. Expect a bit more noise, a firmer ride and slightly lower MPG than you'd get with an all-season.
Can I mix all-terrain and all-season tires on the same vehicle?
It's best not to. Different tread designs grip differently, which can upset handling in wet or loose conditions. Both Michelin and BFGoodrich tell drivers to check the owner's manual before mixing tire types. On a dually, each rear pair should always match in size, type and wear.
Is an all-weather tire the same as an all-season tire?
No. An all-weather tire is an all-season-style road tire that also carries the 3PMSF symbol. A basic all-season tire usually carries only the M+S marking, so it hasn't passed the severe-snow test.
Do I need four-wheel drive to benefit from all-terrain tires?
No. The tires are what touch the ground, so A/T tread improves grip on loose surfaces on a 2WD truck too. Four-wheel drive simply lets more wheels use that grip. Our AWD vs 4WD guide explains the difference.
Are all-terrain tires worth it if I only go off-road a few times a year?
Usually not. A good all-season tire handles graded gravel and the occasional campsite road. If those trips involve sharp rock or rough ground, though, the A/T tire's tougher sidewalls can be worth it just to avoid a puncture far from help.
