The Ironman All Country AT-X has an all-terrain tread and a light-truck designation, making it one of two off-road capable tires in this size. Its 116T load index matches the Goodyear and Firestone, covering typical half-ton loads. It is the only all-terrain option without an XL (extra load) designation, so it carries less weight than the Crosswind.

Pros

• All-terrain tread pattern
• Light-truck construction
• 116T load index
• Suitable for mud and gravel

Cons

• Not an XL (extra load) tire
• All-terrain tread adds rolling resistance on pavement
• No ply count stated

Good fit if

• Light truck owners who occasionally leave the highway
• Drivers wanting a tougher tread for ranch or work roads

Skip if

• You never drive off pavement
• You need the highest possible load capacity

Verdict: A capable all-terrain tire for light trucks that see mixed use.

The Crosswind Rugged Traxx is the only all-terrain tire here with an XL (extra load) designation, meaning it can carry more weight at higher inflation pressures than a standard load tire. Its 116T load index is the same as the Ironman, but the XL construction gives it a higher load capacity at maximum pressure. This makes it the best choice for light trucks that regularly tow or carry heavy cargo.

Pros

• XL (extra load) construction
• All-terrain tread
• 116T load index
• Light-truck designation

Cons

• No highway-oriented tread
• May feel stiffer on road due to extra load capacity
• Ply count not stated

Good fit if

• Light truck owners who tow or haul near capacity
• Drivers who want an aggressive look and off-road grip

Skip if

• You drive mostly on smooth highways
• You need a tire for a car or crossover not rated for LT sizes

Verdict: The sturdiest all-terrain pick for heavy-duty light-truck use.

The Firestone Destination LE3 is a highway-terrain tire for cars and SUVs, with a 116T load index. Unlike the Goodyear's street radial designation, this tire's name indicates a dedicated highway terrain pattern. It shares the same load index as the Goodyear and Ironman but is not for light trucks or extra load.

Pros

• Highway-terrain tread design
• 116T load index
• Designed for cars and SUVs
• From a major brand

Cons

• No all-terrain capability
• Tread pattern not detailed by seller
• Not for light trucks or heavy loads

Good fit if

• SUV owners who prioritize paved-road stability
• Drivers who want a dedicated highway tire from an established maker

The GT Radial Savero HT2 is the only all-season tire in this list, designed for cars and SUVs. It comes as a set of four, which simplifies a full replacement. Its 114T load index is the lowest among the picks, so it is suited for passenger vehicles that do not approach heavy load limits.

• Complete set of four tires
• Designed for cars and SUVs
• Highway-oriented tread pattern

Cons

• Lower load index (114T) than competitors at 116T
• No light-truck or XL option
• Not for heavy towing or hauling

Good fit if

• Drivers who want a matched set without shopping individually
• Crossover owners in temperate climates with light loads

Skip if

The GT Radial Savero HT2 also comes as a set of two, offering a smaller purchase for those who need only a pair of tires, perhaps for the front axle. It shares the same all-season tread and 114T load index as the set of four, so the only difference is the quantity.

Pros

• All-season tread for year-round use
• Sold as a pair for partial replacement
• Designed for cars and SUVs
• Same tire as the set of four

Cons

• Lower load index (114T) than competitors at 116T
• Not a complete set, may require matching with existing tires
• No light-truck or XL option

Good fit if

• Owners replacing only two tires on the same axle
• Drivers who want the same GT Radial model but need fewer tires

Skip if

• You need all four tires at once
• You require a higher load capacity

Verdict: A practical option for replacing two tires with a proven all-season model.

Specifications side by side

How the picks were chosen

The pool for this size contained six listings at the time of writing. Each listing was reviewed for tread type, vehicle type, load index and speed symbol, and rim size from the seller's description. Two of the listings were for the same GT Radial model in different quantities (set of two and set of four) and were treated as separate products. Prices are live and update when the listing changes; no ranking is based on price. No tire has been tested on a vehicle, and all conclusions rest solely on published specifications and the maker's own descriptions.

Picking the right one for you

Understand load index and speed symbol

The load index is a numerical code that indicates the maximum weight a tire can support at the inflation pressure specified by the manufacturer. For example, a 116T tire has a load index of 116, which corresponds to 2,755 pounds. The letter T is the speed symbol, meaning the tire is certified for speeds up to 118 mph. The federal load limit requirements are specified in 49 CFR 571.110; the sum of the maximum load capacities of the tires on an axle must not be less than the gross axle weight of that axle. For heavy loads, choose a tire with a higher load index or an XL (extra load) designation, which allows higher inflation pressure.

Match the tire type to your driving surface

Tires come in three broad tread families: all-terrain, all-season, and highway-terrain. All-terrain tires have larger, more aggressive blocks for off-road grip, but they create more noise and rolling resistance on pavement. All-season tires balance dry, wet, and light snow performance, making them a good default for daily drivers. Highway-terrain tires prioritize smoothness and stability on paved roads, with shallower treads that improve fuel economy. The 275/65R18 pool includes all three, so choose based on where you spend most of your miles.

Check the vehicle type designation: LT vs P-metric

Tires are labeled as either light truck (LT) or passenger car (P-metric) sizes. The 275/65R18 tires here come in both: the Ironman and Crosswind are designated for light trucks, while the Goodyear, Firestone, and GT Radial are for cars and SUVs. LT tires have thicker sidewalls and higher load capacities, but they often produce a firmer ride. If you drive a half-ton pickup or a heavy SUV, an LT tire may be safer. If you use a crossover or a sedan, a P-metric highway tire usually gives a smoother ride and better fuel economy. Federal regulations in 49 CFR 571.139 apply to radial tires for vehicles up to 10,000 pounds GVWR, including both types.

Decide between a single tire and a set

Some listings sell tires individually, which is useful if you are replacing one damaged tire. Others, like the GT Radial Savero HT2, come as a set of four or a set of two. Buying a full set ensures matching tread depth and brand, which is important for even wear and consistent handling, especially on all-wheel-drive vehicles. If you need only one tire, the individual listings for the Ironman, Goodyear, Crosswind, and Firestone are the way to go. Always check your owner's manual for the recommended replacement interval if you replace just one tire.

Questions

What does the 116T on a 275/65R18 tire mean?

The 116 is the load index, the maximum weight the tire can support when inflated to its specified pressure. For index 116, that is 2,755 pounds. The T is the speed symbol, meaning the tire is certified for continuous speeds up to 118 mph. These numbers are stamped on the sidewall and follow guidelines from the federal standard in 49 CFR 571.109 and 571.139.

Can I use a 275/65R18 tire on a 18-inch rim even if my truck is not listed?

The size 275/65R18 indicates a tire designed to fit an 18-inch rim. However, the vehicle's recommended tire size and load capacity should be checked against the tire and loading information label on the driver's side door jamb or in the owner's manual. Federal safety standards (49 CFR 571.110) require that the sum of the tire load capacities on an axle meet or exceed the axle's gross axle weight.

Are all-terrain tires like the Ironman or Crosswind safe for highway driving?

Yes, all-terrain tires are designed for mixed use and can be driven on highways, but they often produce more road noise and reduce fuel economy compared to highway or all-season tires. The tread pattern is more aggressive, which improves off-road grip but may feel less stable at high speeds. Always ensure the tire is inflated to the vehicle manufacturer's recommended pressure, as under-inflation can increase wear and reduce handling.

Why do the load indexes differ between the GT Radial and the others?

The GT Radial Savero HT2 carries a 114T load index, meaning 2,601 pounds per tire, while the Goodyear, Ironman, Crosswind, and Firestone are 116T at 2,755 pounds. The difference is a weight capacity of 154 pounds per tire. If your vehicle is near its gross weight limit, you should choose a tire with a higher load index or an XL (extra load) designation. The federal standard for tire selection (49 CFR 571.110) requires that the tire's load capacity at the recommended inflation pressure be adequate for the actual load on the vehicle.
