Pickup Truck Tires: Load Range and Off-Road Options

Start With Load Range, Not Tread Pattern

The first decision for a pickup truck tire is load range, not tread pattern. Federal rules define load rating as the maximum load a tire is rated to carry for a given inflation pressure, and maximum load rating as the rating at the tire's maximum permissible inflation pressure. If the tire cannot carry the weight on the axle, the tread pattern will not save it.

Your truck's certification label and tire placard list the original tire size, the gross vehicle weight rating (GVWR), and the gross axle weight rating (GAWR) for each axle. The tire selection standard for heavier vehicles requires that the sum of the maximum load ratings of the tires fitted to an axle must not be less than the GAWR of that axle system. A similar rule under Standard No. 110 covers vehicles with a GVWR of 10,000 pounds or less. Start with those numbers, then compare tires in Best Light Truck Tires in 2026 and Best All Terrain Tires in 2026.

• Check the door placard for the vehicle manufacturer's recommended tire size and cold inflation pressure.
• Find the GAWR of each axle on the certification label.
• Choose tires whose combined load rating meets or exceeds that GAWR, then move to tread pattern.

Match Load Range to Work and Towing

When a pickup works, tire capacity works with it. Load range describes the tire's load-carrying structure, and the letters you see on LT tires, such as C, D, E, and F, are shorthand for comparing that capacity. The number that matters for safety is the load rating at the inflation pressure you plan to run, so compare ratings, not just the sidewall branding.

For trucks that tow or haul near their limits, an LT tire is usually the right path. Federal rules define a light truck (LT) tire as one designated by its manufacturer as primarily intended for use on lightweight trucks or multipurpose passenger vehicles. They also require the load rating of a passenger car tire installed on a truck to be divided by 1.10 before calculating axle capacity. That reduction is why a P-metric size that works on an SUV can come up short on a pickup.

• Tow or haul near the truck's ratings: choose an LT tire and verify its load rating at your planned pressure.
• Daily driving with light loads: a passenger car tire can ride well, but apply the 1.10 reduction when checking axle capacity.
• Heavy loads in the bed: consider a higher load range and confirm the rim width. See Tire Load Index and Tire Load Index for Towing.

Understand P-Metric vs LT on a Pickup

Tire type matters as much as tread. A passenger car tire, often labeled with a P-metric size, is intended for passenger cars, multipurpose passenger vehicles, and trucks with a GVWR of 10,000 pounds or less. An LT tire is designated by its manufacturer as primarily intended for use on lightweight trucks or multipurpose passenger vehicles. Pickups can legally use either type, but the standards treat them differently when the truck needs load capacity.

There is also an extra load tire category. Standard No. 139 defines an extra load tire as one designed to operate at higher loads and higher inflation pressures than the corresponding standard tire. Extra load tires can add capacity in a passenger-car size without moving to a full LT tire. Standard No. 139 covers new pneumatic radial tires for light vehicles and excludes light truck tires with a tread depth of 18/32 inch or greater, which fall under Standard No. 119 instead. Compare the trade-offs in P-Metric vs LT Tires.

Pick a Tread Pattern by Terrain

After the load range is settled, choose the tread. Highway terrain tires use a continuous rib design and are quiet on pavement, which suits pickups that stay on roads and carry moderate loads. All-terrain tires add larger tread blocks and more open space for gravel, dirt, and light mud while remaining acceptable on the highway. Mud-terrain tires go further with an aggressive, open tread for mud and rocks, at the cost of noise and faster wear on pavement. See Highway Terrain vs All Terrain Tires and Mud Terrain vs All Terrain.

For most owners, an all-terrain is the best compromise. A dedicated work truck that rarely leaves pavement can use highway terrain. A truck that regularly crosses mud, deep gravel, or rocky trails needs mud-terrain. Remember that an aggressive tread does not replace load range: a mud-terrain tire in a light load range can still be overloaded when the bed is full.

Off-Road Choices for a Pickup

Off-road pickups need both traction and structure. Standard No. 119 applies to new pneumatic light truck tires with a tread depth of 18/32 inch or greater on vehicles with a GVWR of 10,000 pounds or less, and it sets endurance, strength, and high speed performance requirements. In practice, deep-tread LT tires built for off-road use are held to a dedicated set of tests, which is one more reason to choose an LT tire when you plan to leave the pavement.

Before buying larger off-road tires, verify ground clearance, suspension clearance, and the effect on the speedometer. A tire that rubs at full lock is a safety problem, not an upgrade. For off-road pressure strategy, see Off-Road Tire Pressure.

Inflation and Tire Pressure Monitoring

Tire pressure is part of load range. A tire's load rating is quoted for a given inflation pressure, so running below the vehicle manufacturer's recommended cold inflation pressure reduces the weight the tire can safely carry. The TPMS standard requires vehicles with a GVWR of 10,000 pounds or less to warn the driver when one or more tires falls to 25 percent below that recommended cold pressure or to a threshold in the standard, whichever is higher.

Use the placard pressure, not the maximum pressure molded on the sidewall. The U.S. Department of Energy notes that under-inflated tires can lower gas mileage by about 0.2 percent for every 1 psi drop in average tire pressure. For off-road work, many drivers lower pressure for traction on soft ground, but return to the placard pressure before highway driving. See How Much Air Do Your Tires Need? A PSI Guide and TPMS Explained.

Match Rims and Service to the Tire

A pickup tire is only as good as its rim match. Federal standards require tire manufacturers to make available a listing of the rims that may be used with each tire, and they recognize publications from organizations such as The Tire and Rim Association, ETRTO, and other standard bodies as sources for that information. Verify rim width range and bolt pattern before mounting a non-stock tire. See Tire Rim Width Range.

Service also protects the investment. Proper mounting, balancing, rotation, and inspection help a correctly chosen load range stay within its design limits. Uneven wear is a sign to fix the cause before the next set of tires.

What to pick for your use

Questions

What does load range mean on a pickup truck tire?

In Federal standards, load rating is the maximum load a tire is rated to carry for a given inflation pressure, and maximum load rating is that rating at the tire's maximum permissible inflation pressure. Load range is the shorthand name for that load-carrying structure on light truck tires. Match the tire's load rating to the axle's gross axle weight rating, then choose a tread for the terrain. See Tire Load Range for Light Trucks.

Is an LT tire always better on a pickup?

Not always. LT tires are designated primarily for light trucks and multipurpose passenger vehicles and usually have more robust construction for work and towing. A passenger car tire can work for a lightly loaded pickup, but Federal rules divide its load rating by 1.10 when it is installed on a truck. Compare real axle capacity, not just the tire type.

What tire pressure should I run on a pickup?

Use the vehicle manufacturer's recommended cold inflation pressure from the placard or owner's manual, not the maximum pressure molded on the sidewall. The TPMS standard requires vehicles up to 10,000 pounds GVWR to warn at 25 percent below the recommended cold pressure, but checking pressure manually is still important, especially after a load change.

Can I use a P-metric tire for towing?

Only if the reduced load rating still covers the axle load. A passenger car tire installed on a truck has its load rating divided by 1.10 before calculating axle capacity. For towing near the truck's limits, an LT tire is the safer choice.

How do I choose between all-terrain and mud-terrain tires?

All-terrain tires balance on-road comfort with light off-road traction. Mud-terrain tires use an aggressive open tread for mud, rocks, and ruts but add noise and highway wear. Choose all-terrain for gravel, dirt, and forest roads, and mud-terrain for serious off-road use. Keep the load range matched to the truck's axle ratings either way.
