Toyo Open Country M/T Mud‑Terrain Tires
Built for harsh terrain, the Toyo Open Country M/T delivers confident traction, dependable durability, and a bold look that fits work and weekend use. Deep, open tread blocks bite into mud and loose surfaces, and wide voids clear debris to keep the contact patch engaged. A reinforced casing and strong sidewalls add stability under load and help guard against punctures on rocks and ruts. On pavement, it tracks predictably when properly inflated and rotated. If your build needs a tire that handles jobsite demands and heads straight to the trail, the Open Country M/T is a proven performer.
Key Features and Specifications
The Open Country M/T uses an aggressive, directional-inspired tread with large, scalloped shoulder lugs for lateral bite and extra traction when aired down. Wide, self-cleaning channels shed mud and stones to maintain grip, and staggered blocks help on uneven terrain. A cut and chip resistant compound supports long service in abrasive conditions. Reinforced sidewalls and robust beads improve stability with heavy loads and add impact protection off-road. Select sizes carry higher load ratings for towing or gear-heavy builds. Tread depth and weight vary by size, so review the specs for your exact fitment. The focus is traction, protection, and consistent wear when maintained correctly.
Off‑Road Traction and Durability
In deep mud, the widely spaced lugs bite and clear quickly, helping you keep momentum in ruts and clay. On rocky trails, the sturdy sidewall and blocky shoulders add grip at lower pressures and help shield against sharp edges. The durable compound resists cuts and chipping in gravel and lava rock, and stone ejectors help reduce drilling. In sand, its broad footprint at lower psi improves flotation and forward bite. Whether you are crawling, hauling, or exploring, the M/T is built to deliver reliable traction and casing strength so you can focus on your line.
On‑Road Manners and Noise
Mud-terrain tires trade some on-road refinement for off-road grip. The Open Country M/T tracks well for its class, but expect more tread hum than an all-terrain, especially as it wears. Set pressures to your vehicle's door jamb label, rotate every 5,000 to 6,000 miles, and keep alignment in spec to even out wear and slow noise growth. In the wet, drive conservatively, allow extra braking distance, and avoid abrupt inputs. If you split time between highway and trail, this tire strikes a workable balance, with the understanding that quietness and fuel economy will not match less aggressive patterns.
Sizes and Fitment Guide
Choose your Open Country M/T size based on the door jamb placard and your build goals. Stock-fit sizes suit daily duty and towing, while upsized options add ground clearance and traction for trails. Popular picks include 35x12.50R20, 285/75R16, 285/70R17, and 315/75R16. Lift height, wheel width and offset, and potential trimming determine if an upsized tire will clear at full lock and compression. Match load rating to your vehicle's requirements, verify speed and load indices, and confirm wheel specs. If unsure, our fitment team can cross-check your setup to deliver the stance and performance you want without rubbing.
Popular Open Country M/T Sizes
- 35x12.50R20: A go-to for lifted half-ton and three-quarter-ton trucks seeking added clearance and a bold stance. Check wheel offset and crash bar clearance.
- 285/75R16: A classic tall-and-narrow choice for older trucks and overland builds, good ground clearance with moderate width.
- 285/70R17: A popular upsized fit on many modern trucks, often works with mild lifts or level kits.
- 315/75R16: A substantial jump in diameter and width, typically needs a lift, gearing considerations, and careful wheel selection.
Price and Buying Options
Open Country M/T pricing varies by size, load rating, and availability. Larger diameters and higher load indices cost more due to added materials and capacity. Save time with wheel and tire packages that arrive mount-ready, or ship to a trusted installer for quick service. Watch for seasonal promotions and rebates to stretch your budget. Beyond the sticker price, plan for installation, TPMS service, an alignment check, and regular rotations. Proper setup helps the tire wear evenly and can extend usable life, lowering your cost per mile.
Open Country M/T vs Alternatives
If you spend real time in mud, ruts, or rocky trails, the Open Country M/T's large voids and strong sidewalls outshine hybrid and all-terrain patterns. For daily driving with occasional dirt, a rugged-terrain or all-terrain option will ride quieter and stop shorter in the wet, trading some deep-mud bite. Within Toyo's lineup, the Open Country R/T blends off-road traction with better road manners for highway-heavy use. Across brands, the trade-offs are similar, more aggressive tread improves loose-surface grip but adds noise and rolling resistance. Choose based on where you drive most.
Ownership Tips and Maintenance
Start with proper fitment and OE-recommended pressures for daily driving. Rotate every 5,000 to 6,000 miles, and use a 5-tire pattern if you carry a matching spare. Realign after suspension work or hard impacts. Off-road days call for careful air-down and reinflation before highway speeds. Inspect sidewalls and tread for cuts or embedded stones, and rebalance as needed, large lugs can magnify imbalances as they wear. For winter, remember that mud-terrain designs have limited siping, drive conservatively on packed snow and ice or run a dedicated winter set in severe climates.

Do you have a question about Open Country M/T 40X13.50R17LT C 121Q?
The Toyo Open Country M/T is manufactured at Toyo's U.S. facility located in Bartow County, Georgia. This modern factory ensures high-quality production standards for all Toyo tires.
Large tread blocks and wide voids create more air pumping noise than less aggressive patterns. When new and properly balanced, the Open Country M/T is manageable for daily commutes, but hum often increases as edges wear. You can slow noise growth by rotating on schedule, maintaining correct pressures, and keeping alignment in spec. Choosing wheels with proper offset and a hub-centric fit also helps. If cabin quiet is a top priority, consider a rugged-terrain or all-terrain alternative.
Tread life depends on driving style, load, alignment, and rotation habits. Off-road use, heavy towing, underinflation, and aggressive throttle shorten life. Careful pressure management and rotations every 5,000 to 6,000 miles can extend it. Mud-terrain tires typically do not carry a mileage warranty, so real-world results vary. Monitor tread depth across the face, correct cupping early, and keep suspension components in good condition to maximize longevity.
In unpacked or deep snow, the open tread can bite and self-clean. On packed snow and ice, like most mud-terrains with limited siping, traction and braking are more challenging than with dedicated winter or heavily siped all-terrain tires. In cold climates, drive conservatively, allow extra stopping distance, and consider a winter set if icy roads are common. Cold weather lowers tire pressure, so check and adjust psi regularly.
Yes, if you need real off-road traction and accept the trade-offs. The Open Country M/T delivers strong grip in mud and on rocks with a durable casing for rough use. On pavement, expect more tread hum and higher rolling resistance than an all-terrain or highway tire, especially as the tread wears. Proper inflation, routine rotations, and a quality alignment help keep ride and handling predictable. If most of your miles are highway with light trails, a less aggressive pattern will be quieter.
The Open Country M/T is generally covered by a standard limited warranty for workmanship and materials. Mud-terrain tires typically do not include a treadwear mileage warranty. Coverage terms and adjustment policies can vary by region and seller, so review the current Toyo warranty booklet and your retailer's policies. Register your tires, keep proof of purchase, maintain recommended pressures, and follow rotation and alignment intervals to support eligibility and promote even wear.
The Open Country M/T comes in a wide range of diameters and load ratings for trucks and 4x4s. Popular sizes include 35x12.50R20, 285/75R16, 285/70R17, and 315/75R16, with availability varying by region and season. Always verify fitment against your vehicle's door jamb placard, wheel width and offset, and lift height. Upsizing may require trimming, gearing changes, or recalibration. Share your current tire size and wheel specs, and we can confirm compatible options.
