What Does 37x12.50R20 Mean?

Understanding your tire size protects you from ordering the wrong set. Here is what each number tells you:

*Number*	*What It Means*
37	Overall tire height: 37 inches
12.50	Tread width: 12.50 inches
R	Radial construction
20	Wheel diameter: 20 inches

This is a Light Truck (LT) size. Most 37x12.50R20 tires carry a Load Range E (10-ply) or Load Range F (12-ply) rating. Load Range E handles the majority of lifted truck builds. Load Range F suits heavier payloads, regular towing, and demanding off-road use. Speed ratings run primarily Q (99 mph) and R (106 mph), both appropriate for trail use and highway driving.

Which Trucks and SUVs Run 37x12.50R20 Tires?

This size is purpose-built for lifted light trucks and 4x4 platforms. Most builds require a suspension lift to run this size without rubbing. Common fitments include:

*Vehicle*	*Minimum Lift Required*
Ford F-150 (2015 and newer)	3.5 to 4 inch lift
Ram 1500 (2019 and newer)	4 inch lift
Chevy Silverado 1500	4 inch lift
GMC Sierra 1500	4 inch lift
Jeep Wrangler JL	2.5 inch lift
Jeep Gladiator JT	2 inch lift
Toyota Tundra (2022 and newer)	3.5 inch lift
Ford F-250 and F-350	Little to no lift required

Always confirm clearance with your installer before ordering. Rubbing against suspension components creates safety hazards and accelerates tread wear on the edges.

Best 37x12.50R20 All Terrain Tires

All terrain tires in this size give you genuine trail capability without sacrificing highway manners. They perform well year-round across gravel, packed dirt, loose rock, light mud, and wet pavement. If you spend more time on the road than off, all terrain is your best value.

Nitto Ridge Grappler LT 37x12.50R20 126Q E The Ridge Grappler ranks as one of the top choices for lifted truck owners nationwide. Its hybrid tread pattern blends all terrain structure with mud terrain aggression. Stone ejectors protect tread blocks from rock drilling, and reinforced sidewalls add trail confidence on sharp obstacles.

Mickey Thompson Baja Boss A/T LT 37x12.50R20 126Q E Backed by a 50,000-mile tread warranty, the Baja Boss A/T also carries full Three-Peak Mountain Snowflake (3PMSF) certification. That means it meets federal standards for winter traction performance. If you drive in snow states, this is one of the safest choices in this size. You can verify the 3PMSF standard through the U.S. Department of Transportation.

Atturo Trail Blade ATS LT 37x12.50R20 126Q E The Trail Blade ATS is the value leader in the all terrain category for this size. An open shoulder design improves off-road bite, and strong sidewall construction protects against trail damage. If you want capable all terrain performance at a lower price point, this is where to start.

Best 37x12.50R20 Mud Terrain Tires

Mud terrain tires use wide, open tread blocks that self-clean in thick mud, clay, and loose terrain. They prioritize traction in extreme conditions over tread longevity. Most mud terrain tires in this size carry no mileage warranty. If the pavement is the exception rather than the rule, a mud terrain is the right choice.

1 - Mickey Thompson Baja Boss M/T LT 37x12.50R20 126Q E The Baja Boss M/T is a dedicated mud and rock tire. Its PowerPly XD sidewall uses three layers of reinforcement against punctures and cuts. A staggered block tread pattern delivers consistent bite in mud, rocks, and rutted terrain.

2 - Goodyear Wrangler Boulder MT LT 37x12.50R20 126Q E Goodyear engineered the Wrangler Boulder MT specifically for rock crawling. A soft tread compound conforms to irregular rock surfaces for maximum grip. Protective tread blocks resist chipping and tearing in rough conditions.

3 - Yokohama Geolandar M/T G003 LT 37x12.50R20 126Q E The Geolandar M/T G003 balances aggressive mud performance with wet road stability. Yokohama uses a triple polymer compound to maintain consistent grip across temperature ranges, making this a strong year-round option for truck owners in variable climates.

4 - Kumho Road Venture MT71 LT 37x12.50R20 126Q E The MT71 runs aggressive stone ejectors across the full tread width to clear rocks and debris without retention damage. A strong choice for deep ruts and rocky trail systems.

5 - Maxxis Razr MT LT 37x12.50R20 128Q F The Razr MT stands out in this size with a Load Range F (12-ply) rating for maximum load capacity and sidewall strength. If you run a heavier build or carry serious loads on the trail, the Razr MT delivers the structural integrity to match.

37x12.50R20 Rugged Terrain Tires

Rugged terrain tires fill the space between all terrain and mud terrain. They handle trail conditions better than a standard A/T but remain quieter and more comfortable than a dedicated mud tire. This makes them a smart pick for daily drivers who hit the trails on weekends.

Cooper Discoverer Rugged Trek LT 37x12.50R20 126Q E The Rugged Trek leads this size category with the longest tread warranty available: 55,000 miles. It also carries Three-Peak Mountain Snowflake certification for winter traction. Whisper Groove technology actively reduces highway noise, so this tire drives quietly on the daily commute. If you want maximum value and year-round confidence from a single tire, the Rugged Trek is hard to beat.

Evoluxx Rotator R/T LT 37x12.50R20 128Q F The Rotator R/T delivers Load Range F strength at a budget-friendly price. Its 50,000-mile tread warranty makes it one of the most economical long-wearing options in this category. A solid performer on unpaved roads and light to moderate trails.

How to Choose the Right 37x12.50R20 Tire

1 - Match the tread to your terrain. An all terrain tire works best when your driving is split between pavement and trails. A mud terrain performs at its best when paved road is the exception. A rugged terrain covers the middle ground for drivers who do both regularly.

2 - Choose the right load range. Load Range E (10-ply) handles most lifted truck applications without issue. Load Range F (12-ply) suits heavier builds, frequent towing, or demanding off-road conditions. Both options are available across the New American Tires Hub collection in this size.

3 - Check the tread warranty. Mud terrain tires typically carry no mileage warranty due to their aggressive compound. All terrain and rugged terrain tires in this size range from 40,000 to 55,000 miles. The Cooper Discoverer Rugged Trek leads at 55,000 miles.

4 - Confirm winter certification if you need it. Not all 37x12.50R20 tires pass Three-Peak Mountain Snowflake certification. If you live in a snow state, confirm this rating before ordering. The Mickey Thompson Baja Boss A/T and Cooper Discoverer Rugged Trek both carry it in this size.

5 - Decide on sidewall style. Most options in this size come with black sidewalls. Some models offer Raised White Letters (RWL) or Raised Black Letters (RBL) for a more aggressive visual look.

Tire Maintenance for 37x12.50R20 Fitments

Oversized tires on lifted trucks need more attention than standard fitments. Following these guidelines protects your investment and keeps your warranty valid.

Rotate your tires every 5,000 to 6,000 miles. Lifted trucks create uneven wear patterns, especially on the front axle. Regular rotation extends tread life significantly.

Check tire pressure monthly. Larger tires lose pressure faster in cold weather. Most 37x12.50R20 tires run between 35 and 55 PSI depending on load range and vehicle weight.

Inspect sidewalls after every off-road run. Look for cuts, bulges, or embedded debris. Load Range F sidewalls resist damage better, but no sidewall is fully puncture-proof.

Keep alignment and balance current. Improper alignment accelerates shoulder wear and causes handling issues at highway speeds. This matters more on lifted platforms than on stock height vehicles.
