The BFGoodrich All-Terrain T/A KO3 is listed in a light-truck size, LT275/70R18, with an E load range and a 125/122S load and speed index. That makes it a heavier-duty option than the car and SUV all-terrains in this guide while keeping a common 18-inch fitment. It is the pick to compare first for a pickup or SUV that needs an LT all-terrain.
Pros
- LT275/70R18 size with an LT designation

- 125/122 load index is stated
- 18-inch rim diameter fits many modern trucks and SUVs
Cons
- Covers only the 18-inch size in this listing

- Drivers who want a 70-series sidewall in a common truck size
Skip if
- Crossover owners who only need a P-metric or XL tire

Verdict: The BFGoodrich All-Terrain T/A KO3 LT275/70R18 is the best overall pick because it pairs a light-truck size with an E load range in a common 18-inch fitment.

The Toyo Open Country A/T III is listed as a 265/70R17 115T car and SUV tire, making it a closer fit for daily drivers than the E-load light-truck picks above. The 70-series sidewall and 17-inch diameter cover a common truck and SUV size without the heavier LT construction. It also carries a T speed symbol, which is higher than the S speed symbol used by some all-terrains in this guide.
Pros
- 265/70R17 is a widely used truck and SUV size
- 115T load and speed index is stated in the listing
- Car and SUV classification, not a heavier LT truck tire

The Goodyear Wrangler Territory AT is listed as a 275/60R20 XL 116 H car and SUV tire. Of the 20-inch car and SUV picks, it has a higher speed symbol than the Pirelli and Nitto options in this section.

The Falken Wildpeak A/T Trail is listed as a 255/50R20 109V XL car and SUV tire. Its V speed symbol is the fastest of the 20-inch all-terrains in this guide, and the narrower 255 width fits crossover wheels better than 275 or 285 tires.

Pros
- 255/50R20 size fits many modern crossovers
- V speed symbol is the fastest among 20-inch picks in this guide

The Pirelli Scorpion All Terrain Plus is listed as a 275/60R20 115T car and SUV tire with no LT or E-load designation. Among the 20-inch car and SUV picks, it sits between the Goodyear H speed symbol and the Nitto S speed symbol, making it a middle-ground all-terrain for SUV drivers.

The Continental TerrainContact A/T is listed as a 285/45R22XL 114H tire, and it is the only pick here with a 22-inch rim diameter.

The Nitto Recon Grappler A/T is listed as a 275/60R20XL 116S car and SUV tire, giving 20-inch truck and SUV owners an XL option if they do not need the LT and E load range of the Armstrong pick. The S speed symbol is lower than the Goodyear H and Falken V, so it is not aimed at sustained high-speed driving. It is the middle option between the passenger-car Goodyear and the E-load Armstrong in this guide.
Pros
- 275/60R20 is a common light-truck and SUV size
- XL designation is stated for extra capacity

The Firestone Transforce AT2 is listed as an LT235/80R17 120R E C commercial light truck tire.

The Bridgestone Duravis M700HD is listed as an LT265/70R17 121R E commercial light truck tire, pairing a 17-inch LT size with an E load range and a commercial designation.

The Milestar Patagonia A/T R is listed as an LT235/80R17 E (10 ply) tire, which gives it an E load range in a 17-inch size without the commercial designation of the Firestone and Bridgestone picks. The 80-series sidewall is the tallest ratio among the 17-inch tires here. It is another 17-inch E-load option for pickups that do not need a commercial fleet label.
Pros
- LT235/80R17 E 10-ply load range
- 17-inch rim diameter
- No commercial designation, so it is aimed at private light trucks
- Tall 80-series sidewall is stated in the size

The Armstrong Tru-Trac AT is listed as an LT285/55R20 122/119S E (10 ply) tire, making it the only LT-size and E-load pick in the 20-inch group. It brings the dual load index that light-truck owners often look for, and its 55-series sidewall sits between the tall 70-series off-road tires and the low-profile 45-series Continental.

Pros
- LT285/55R20 with E 10-ply load range
- 122/119 dual load index is stated
- Only LT-size tire in the 20-inch group

The Westlake SL369 is listed as an LT275/70R18 125/122S E/10 tire, and it gives 18-inch truck owners a second E-load option alongside the BFGoodrich pick.

Pros
- LT275/70R18 with E/10 load range
- 125/122 dual load index is stated
- 70-series sidewall in a common 18-inch truck size

The Ironman All Country AT-X is listed as a 275/65R18 116T light truck tire, with a T speed symbol and no E load range. It fills the gap between the heavier E-load 18-inch tires and the passenger-car 20-inch picks: a light-truck listing in a common 18-inch size for owners who do not need 10-ply capacity. It is also the only 18-inch pick here that keeps a 65-series sidewall rather than a 70-series.
Pros
- 275/65R18 size with a light-truck listing
- 116T load and speed index is stated

The Aplus Shredder A/T is listed as an LT245/75R16 120/116Q tire, and it is the only 16-inch light-truck pick in this guide. That gives owners of older or smaller pickups a current all-terrain option without stepping up to a 17-inch or larger wheel. Its Q speed symbol is the lowest in this list, so it is suited to local and off-road use rather than sustained high-speed highway running.
Pros
- LT245/75R16 size for 16-inch trucks
- 120/116 dual load index is stated in the listing
- 75-series sidewall is part of the stated size

Specifications side by side
How the picks were chosen
The pool started with 138 listings that met the All Terrain tread filter. After folding near-duplicate listings, 60 remained. We kept tires from named manufacturers, avoided repeating the same model in multiple sizes, and shortlisted across vehicle fit: light trucks, cars and SUVs, and ATVs/UTVs. The 15 picks include 8 light-truck listings, 6 car and SUV listings, and 1 ATV/UTV set. We did not use customer comments, and we did not test any tire. Prices shown on the page are live, so they can change. Every specification cited here comes from the pool data or from the maker's own listing.
Picking the right one for you
Start with the vehicle's tire size and load index
Federal safety standards require that each axle be equipped with tires whose combined maximum load capacity is at least the axle's gross weight. Under FMVSS No. 110 and No. 120, tire selection starts with the load capacity needed for that axle, not with tread pattern. All-terrain tires in the pool are sold in passenger-car sizes, XL sizes, LT sizes, and commercial light-truck sizes; check the vehicle placard before comparing tread designs.
Know the difference between an LT tire and a passenger-car tire
FMVSS No. 139 defines a light truck (LT) tire as one intended primarily for use on lightweight trucks or multipurpose passenger vehicles. Passenger-car tires are defined for cars, multipurpose vehicles, and trucks with a gross vehicle weight of 10,000 pounds or less. In this guide, LT-prefixed sizes like LT275/70R18 and LT235/80R17 are the heavy-duty options, while car and SUV listings like 275/60R20 and 255/50R20 use passenger-car sizing without the LT prefix.
Read the load index and load range
Load capacity is the maximum load a tire can carry at a given inflation pressure, and FMVSS No. 109 uses that definition as the basis for sidewall labeling. A listing such as LT275/70R18 125/122S gives two load indexes: 125 for single-wheel use and 122 for dual-wheel use. An E or 10-ply load range is a construction and capacity marker seen on many light-truck all-terrains. If the seller does not state a load index, ask for it before assuming the tire can carry your axle load.
Check speed symbol and rim diameter
Speed symbols are part of the size description and run from Q through V in the picks here. They mark the service speed for which the tire is designed, so a Q-speed tire is not the same as an H-speed tire for sustained highway use. Rim diameter also matters: the picks in this guide range from 14-inch ATV/UTV rims to 22-inch SUV rims, and the tire must match a rim size listed by the manufacturer.
Keep tires inflated to the placard pressure
The U.S. Department of Energy and EPA report that keeping tires inflated to the proper pressure can improve gas mileage by 0.6 percent on average, up to 3 percent in some cases, and that under-inflated tires can lower mileage by about 0.2 percent for every 1 psi drop in average pressure. Use the cold inflation pressure from the vehicle placard, not the maximum pressure molded on the tire sidewall. All-terrain tires follow the same rule.
Understand UTQG grades and tire registration
Passenger-car tires are graded for treadwear, traction, and temperature resistance under the Uniform Tire Quality Grading standards in 49 CFR 575.104. Those grades are molded into the tire or placed on a label, and they are intended to help you compare tires within a category. New tires also carry a DOT identification code under 49 CFR Part 574; registering the tire with the manufacturer is part of normal tire safety maintenance.

Are all-terrain tires the same as winter tires?
No. An All Terrain tread label describes the tire's intended surface mix, not winter certification. Under FMVSS No. 139, a snow tire is one that meets a snow traction threshold and is marked with an Alpine Symbol on the sidewall. If you drive on packed snow or ice, do not assume that an all-terrain tire has that certification; check the sidewall symbol and the listing details before relying on it in winter.
What do LT and P-metric sizes mean?
LT stands for light truck, and FMVSS No. 139 defines a light truck tire as one intended primarily for lightweight trucks or multipurpose passenger vehicles. A passenger-car tire is defined for cars, multipurpose vehicles, and trucks with a gross vehicle weight of 10,000 pounds or less. The vehicle placard and owner's manual are the best guide when deciding between a passenger-car tire and an LT tire.
Do I need an E-load or 10-ply tire to tow?
Not by itself. Federal tire selection rules require that the sum of the maximum load capacities of the tires on an axle is not less than the axle's gross weight. An E-load or 10-ply tire is one common way to reach high capacity, but a correctly matched XL or LT tire may be enough for a lighter vehicle. Start with the axle weights and placard, then compare the stated load indexes.
How do I check tire pressure on an all-terrain tire?
Use the cold inflation pressure from the vehicle placard, usually inside the driver's door jamb, and check it when the tires are cold. The number molded on the sidewall is the maximum pressure, not the recommended pressure. The Department of Energy and EPA report that under-inflated tires reduce fuel economy by about 0.2 percent for every 1 psi drop in average pressure, so proper inflation is part of all-terrain tire ownership.
Why do all-terrain tires have different speed symbols?
Speed symbols are part of the standardized tire description and indicate the tire's intended service speed. In this guide you will see Q, R, S, T, H, and V symbols across the picks. The right symbol for your vehicle depends on what the vehicle maker specifies and how you use the tire; a lower symbol may not be suitable for sustained high-speed highway driving.
