31x10.50R15 Tires for Jeep Wrangler, Ford Bronco, Toyota 4Runner and Light Trucks

If your Jeep, truck, or classic 4x4 runs a 15-inch rim, the 31x10.50R15 is one of the most proven tire sizes on American roads and trails. It was factory-specified on some of the most capable vehicles ever built, including the Ford Bronco, Jeep Wrangler YJ and TJ, Toyota 4Runner, and a long list of light trucks that earned their reputation off the beaten path.

At New American Tires Hub, we stock this size across every performance category, from aggressive mud terrains to quiet all seasons. Every tire ships free to your door or installer anywhere in the continental USA. No surprises at checkout. Browse by type, brand, or price and find the right set today.

What the 31x10.50R15 Size Actually Means

Every number in this tire size tells you something useful. Here is a plain-language breakdown before you buy.

31 is the overall diameter in inches. Your tire measures approximately 30.98 inches tall when properly mounted and inflated. That height gives you meaningful ground clearance on trucks and 4x4 platforms without requiring major modifications.

10.50 is the section width in inches. This tire spans roughly 10.5 inches from sidewall to sidewall on a correctly sized rim, giving you a wide contact patch and confident footing on loose or uneven terrain.

R stands for radial construction. All modern light truck tires in this size use radial build, which improves ride comfort, heat management, and tread longevity over older bias-ply designs.

15 is the rim diameter. This tire fits any standard 15-inch wheel. Rim width between 7 and 9 inches is the manufacturer-recommended range for this size.

Load Rating and Ply Rating for 31x10.50R15 LT Tires

Most 31x10.50R15 LT tires carry a C load range with a 6-ply rating. That earns a 109 load index, supporting approximately 2,271 pounds per tire. If you tow a trailer, carry cargo, or run a heavier build, this load capacity keeps you within safe operating limits.

Mud Terrain 31x10.50R15 Tires Built for Real Off-Road Work

Mud terrain tires in this size are engineered for the conditions where your Jeep Wrangler or classic Bronco was meant to shine. Wide, aggressive tread blocks with generous voids between them evacuate mud, clay, and soft soil quickly so the tire keeps biting instead of floating.

New American Tires Hub carries mud terrain options from Yokohama, Mickey Thompson, Accelera, and Haida in this size. Each brand offers a different balance of tread aggression, sidewall strength, and on-road noise so you can match the tire to how you actually wheel.

Mud terrain tires in this size typically carry a Q speed rating, which covers up to 99 mph. They are engineered for trail use rather than sustained highway travel. If your miles are split between dirt and pavement, read the all terrain section below before deciding.

What to Prioritize in 31x10.50R15 MT Tires

Sidewall strength matters as much as tread pattern when you are picking a line through rocks and roots. Reinforced sidewalls resist punctures from sharp debris. Look for a 6-ply or load range C construction as your minimum. Stone ejectors built into the tread grooves add another layer of protection by preventing debris from embedding and causing damage on technical sections.

All Terrain 31x10.50R15 Tires for Daily Driving and Weekend Trails

For most truck and Jeep owners, the all terrain tire is the smarter daily choice. It handles gravel roads, hardpack dirt, and light mud without the road noise, heat buildup, or wear rate of a full mud terrain. If your 4Runner or Tacoma covers mostly pavement with weekend trail runs mixed in, all terrain is the category to shop first.

Tires in our 31x10.50R15 all terrain collection include options with tread warranties up to 60,000 miles. Brands like Cooper, GT Radial, Kumho, and Armstrong deliver consistent performance across a range of price points. You do not need to spend top dollar to get a capable all terrain in this size.

All Terrain vs Mud Terrain: A Practical Guide

All terrain tires brake shorter on wet pavement, run quieter at highway speed, and last longer under everyday driving. Mud terrain tires outperform them in deep mud, loose rock, and technical off-road conditions. A simple benchmark: if less than 20 percent of your driving happens off-road, an all terrain tire will serve you better in every measurable category.

All Season 31x10.50R15 Tires for Year-Round Reliability

All season tires in this size are the right choice when highway comfort, tread life, and wet weather performance matter most. They trade the aggressive lug pattern of off-road tires for better wet grip, lower road noise, and higher mileage ratings.

Several all season options in our catalog include road hazard warranties at no added cost, protecting your purchase against damage from debris. GT Radial, Armstrong, and Cosmo all offer strong all season picks under $130 per tire in this size, making them a smart value for truck and SUV owners who keep most of their miles on pavement.

Winter Traction: 31x10.50R15 Snow Tires for Cold Climate Drivers

Dedicated winter tires in this size use a softer tread compound that stays pliable below 45 degrees Fahrenheit. That flexibility is what gives a true winter tire its advantage on ice and packed snow over any all season option. If you run a lifted Jeep or older 4Runner in northern states, winter-specific tires in this size provide a genuine safety upgrade from November through March. Check the U.S. Department of Transportation tire safety guidelines for recommended practices on seasonal tire changes. Visit our winter section to see what is currently in stock in this size.

31x10.50R15 Equivalent Tire Sizes You Should Know

The closest metric equivalent to 31x10.50R15 is 265/75R15. That size measures approximately 30.65 inches tall and 10.43 inches wide, a diameter difference of just 1.1 percent from the original. Most tire manufacturers and fitment guides treat these two sizes as direct equivalents.

Other metric alternatives worth checking include 255/75R15 for a slightly narrower profile and 275/70R15 for improved cornering stability. Before switching to any alternate size, confirm that the load index and speed rating match your vehicle's requirements.

One practical note on speedometer accuracy: a 31x10.50R15 completes 651 revolutions per mile, while a 265/75R15 completes 658. That small difference is worth noting on vehicles without a programmable speedometer.

Rim Width Requirements for This Tire Size

This tire mounts on wheels between 7 and 9 inches wide. For off-road and all terrain applications, a rim 2 to 3 inches narrower than the section width creates a slightly rounded sidewall profile that helps the tire conform to rocks and uneven obstacles. Do not run this tire on any rim narrower than 7 inches or wider than 9 inches.

Vehicles That Use 31x10.50R15 Tires

How to Choose the Right 31x10.50R15 Tire for Your Truck or Jeep

Start with an honest look at how you actually use your vehicle. The tire that fits your driving does more for you than the one with the most aggressive look.

-- Mostly pavement, occasional dirt: All terrain or all season is the right call. You get better wet grip, lower noise, and longer tread life without sacrificing the capability you actually need.

-- Regular trail and off-road use: Mud terrain is worth the trade-offs. Prioritize sidewall strength and stone ejectors alongside tread pattern when comparing options.

-- Cold climate winters: Look for the three-peak mountain snowflake symbol on the sidewall. That marking means the tire passed standardized testing for severe snow traction, a higher bar than a general all season rating.

-- Towing or heavy loads: Check your vehicle's GVWR and compare it against the total rated load capacity of the tires you are considering. A load range C tire with a 109 load index supports approximately 2,271 pounds per corner, which covers most light truck applications.

-- Tread warranty vs. price: A 60,000-mile warranty at a mid-range price outperforms a bargain tire with no coverage when you calculate cost per mile over the life of the set.

Frequently Asked Questions About 31x10.50R15 Tires

Will 31x10.50R15 tires fit my Jeep Wrangler without a lift kit?

Yes. The Jeep Wrangler YJ and TJ both accommodate 31x10.50R15 tires on stock suspension with no rubbing issues in most configurations. This is one of the reasons the size became so popular with Wrangler owners looking for a meaningful upgrade over factory tires without committing to a full lift. If your Wrangler already has a 2-inch lift or higher, you have even more clearance to work with.

What is the difference between 31x10.50R15 and 265/75R15?

These two sizes are widely treated as practical equivalents. The 265/75R15 measures approximately 30.65 inches in diameter compared to roughly 30.98 inches for the 31x10.50R15. The width difference is similarly small at under a tenth of an inch. You can swap between these sizes without modifying your vehicle in most cases, though you should always confirm load index and speed rating match your requirements before purchasing.

How many miles should I expect from a 31x10.50R15 all terrain tire?

Tread life depends on driving habits, vehicle weight, inflation consistency, and rotation frequency. That said, quality all terrain tires in this size from brands like Armstrong and Cooper carry warranties between 55,000 and 60,000 miles. With proper maintenance including rotations every 5,000 to 6,000 miles and correct inflation, reaching or exceeding those warranty figures is realistic for most drivers.

Are 31x10.50R15 mud terrain tires safe on the highway?

Yes, with some context worth knowing. Mud terrain tires in this size typically carry a Q speed rating, covering speeds up to 99 mph. They are safe for highway use within that rating. What you will notice compared to all terrain tires is more road noise, slightly longer braking distances on wet pavement, and faster tread wear if the majority of your miles are on pavement. They are not unsafe on highways, they are just optimized for somewhere else.

Do I need to recalibrate my speedometer after installing 31x10.50R15 tires?

If you are replacing a tire that is the same size, no adjustment is needed. If you are switching from a smaller factory tire, your speedometer will read slightly slower than your actual speed because the larger tire covers more ground per revolution. The 31x10.50R15 completes 651 revolutions per mile. Compare that figure against your current tire's revolutions per mile to understand the difference. Vehicles with a programmable ECU can be recalibrated by a dealer or shop.

What rim width works best with 31x10.50R15 tires?

The recommended rim width range is 7 to 9 inches. Most owners running this size for off-road use prefer an 8-inch rim, which gives the tire a well-rounded sidewall profile that helps absorb impacts and roll over obstacles. A 9-inch rim stretches the sidewall slightly for a flatter profile that improves cornering stability on pavement. Do not go below 7 inches or above 9 inches with this size.

Can I mix 31x10.50R15 tires with a different size on the same vehicle?

Mixing tire sizes is not recommended. Running different diameters on the same axle creates uneven load distribution and can stress your drivetrain, particularly on 4x4 and AWD vehicles where all four wheels are expected to rotate at matched speeds. If you need to replace fewer than four tires, match the brand, model, and size of your existing tires as closely as possible.

How often should I rotate 31x10.50R15 tires?

Every 5,000 to 6,000 miles is the standard recommendation for light truck tires in this size. Regular rotation evens out wear patterns, particularly on vehicles where the front tires carry more steering and braking load than the rears. Consistent rotation is one of the most effective ways to reach the full mileage warranty on any tire you purchase.

Does New American Tires Hub ship to my location?

We ship free to any address in the continental USA. That includes home delivery and installer drop-ship. If you want the tires sent directly to a shop near you, simply enter the installer's address at checkout. Visit our shipping page for full details on delivery timelines and available options.

What is the best 31x10.50R15 tire for a Ford Bronco or classic truck?

For a classic Bronco used as a weekend driver and occasional trail rig, the Cooper Discoverer Rugged Trek and GT Radial Adventuro AT3 are both excellent all terrain choices that balance capability and road manners. If the Bronco sees serious off-road use regularly, the Mickey Thompson Baja Legend EXP or Yokohama Geolandar MT G003 are the mud terrain picks most trusted by experienced off-road drivers in this size.
