Toyo Open Country R/T Pro LT275/65R20
The Toyo Open Country R/T Pro LT275/65R20 is a smart upgrade for super-duty truck owners who want off-road tread performance in a towing-stable package. Widely used as a stock size on Ford F-250, RAM 2500, and Silverado 2500HD, the 275/65R20 dimension keeps your speedometer accurate and your towing capacity intact while the R/T tread pattern dramatically elevates off-road grip versus factory all-season tires. At approximately 34.1 inches in diameter, you get excellent ground clearance with no lift required on most super-duty platforms. Dual load ratings (126/123Q) support single and dual-wheel configurations. Whether you're towing a trailer to a campsite or exploring forest service roads, the Open Country R/T Pro in this size delivers the rugged-terrain edge that super-duty owners demand.
Overview
The Open Country R/T Pro LT275/65R20 is a rugged-terrain hybrid designed for drivers who need more than a standard all-terrain without committing to the full compromises of a mud-terrain. The LT275/65R20: 275mm (~10.8") wide, 65% aspect ratio, 20" rim. Approximately 34.1" overall diameter. A tall and relatively narrow metric size often used as a factory fitment on super-duty trucks. Excellent for towing stability and highway performance. On pavement, the LT275/65R20 delivers predictable highway handling, confident wet braking, and manageable noise levels for a tire of this tread aggression. Off-road, the open shoulders, staggered lugs, and stone ejectors combine to provide solid traction in dirt, gravel, light mud, and loose terrain typical of trail and overland driving. It is a strong match for super-duty towing with highway stability, work truck duty cycle, mild off-road and overlanding, drivers keeping stock-style dimensions while upgrading to off-road tread, and carries a 126/123Q load rating for dependable performance under demanding conditions.
Key Features & Specifications

- Tall 65-series aspect ratio for enhanced sidewall protection on trails
- Dual-rated (126/123Q) for single and dual super-duty fitments
- Load Range E for heavy-duty towing and payload performance
- R/T tread grips loose surfaces, gravel, and wet roads confidently
- Stone ejectors protect bead area during off-road use
- Highway-balanced tread design reduces road noise significantly
Load Range E construction, load rating 126/123Q, size LT275/65R20. These elements work together to deliver confident traction on and off the road with long-lasting durability.
On‑Road and Off‑Road Performance
On pavement, the LT275/65R20 delivers predictable highway handling, confident wet braking, and manageable noise levels for a tire of this tread aggression. The tread void ratio is tuned to balance mud evacuation with a stable contact patch, so braking and steering remain predictable on wet or dry pavement. In winter conditions, the sipes and block edges help in unpacked snow, though this is not a dedicated winter tire — consider winter tires where conditions are severe. Off-road, the open shoulders, staggered lugs, and stone ejectors combine to provide solid traction in dirt, gravel, light mud, and loose terrain typical of trail and overland driving. Stone ejecting grooves help keep the tread clear, reducing rock drilling and protecting the casing over rough fire roads and construction sites.
Off‑Road Capability
The shoulder lugs and alternating block edges on the LT275/65R20 create side bite in ruts and technical sections. The cut and chip resistant compound limits damage on rocky terrain, and airing down within safe limits increases the footprint for sand and rock crawling — always reinflate before returning to highway speeds. Avoid excessive wheelspin on sharp surfaces, and rotate regularly to keep wear even across drive axles. This size is particularly well-suited for super-duty towing with highway stability, work truck duty cycle, mild off-road and overlanding, drivers keeping stock-style dimensions while upgrading to off-road tread.
Fitment & Compatibility
Trucks: Ford F-250 Super Duty (factory on some trims), RAM 2500 (factory on some trims), Chevrolet Silverado 2500HD, GMC Sierra 2500HD
SUVs: Ford Expedition (2018+), Toyota Sequoia (2022+), Nissan Armada
Off-Road & Specialty Vehicles: RAM 2500 Power Wagon, Ford F-250 Tremor, Chevrolet Silverado 2500 ZR2
Always verify fitment using your vehicle's door-jamb label. Confirm clearance at full steering lock and suspension compression. Larger or wider sizes may require a leveling kit, lift, corrected wheel offset, or minor trimming depending on your specific vehicle configuration.
Sizes & Load Rating
This listing is for size LT275/65R20 with a load rating of 126/123Q (Load Range E).

Do you have a question about Open Country R/T Pro LT275/65R20 E/10 126/123Q?
The Open Country R/T Pro is a rugged-terrain tire that blends all-terrain and mud-terrain traits. It is built for drivers who split time between daily commuting and frequent off-pavement use, like gravel roads, forest trails, job sites, and light to moderate mud. The tread emphasizes off-road bite and durability while maintaining predictable highway manners. If you want more trail traction and protection than a typical A/T without the on-road compromises of a full M/T, this hybrid is a great fit.
On the street, start with the pressures on your vehicle's door-jamb label, then fine tune based on load and wear patterns. Off-road, many drivers air down to increase the footprint for traction and ride comfort, but do so within safe limits for your wheel and tire setup. Use a quality gauge, monitor TPMS, and reinflate before highway speeds. Carry a compressor and recovery gear, and avoid hard impacts at low pressure to protect tires and wheels.
In rain, the grooves and lateral channels help move water away from the contact patch for confident braking and steering, especially with proper inflation and healthy tread depth. In snow, the edges and open shoulders aid bite in unpacked snow, but this is not a dedicated winter tire. For frequent ice or severe winter climates, switch to purpose-built winter tires for best safety and braking. Always drive to conditions and follow local laws for winter fitments.
Real-world tread life varies with driving style, terrain, load, and maintenance. Regular rotations about every 5,000 to 6,000 miles, correct inflation, and proper alignment have the biggest impact on longevity. Warranty terms can vary by region and size, so check the manufacturer's documentation or ask your retailer to confirm coverage for your fitment. If you spend time on gravel or rocky surfaces, inspect tread and sidewalls often to catch uneven wear early and protect the casing.
The Toyo Open Country R/T Pro comes in a wide range of sizes for 16- to 24-inch wheels, with various load ratings including LT and flotation sizes, so it can fit everything from daily drivers to lifted off-road rigs.
Fitment depends on your vehicle's OE size, wheel width and offset, and available clearance. Sizes like 35x12.50R20 and 37x12.50R17 are popular, but larger diameters or wider sections may require a level or lift, proper wheel offset, and possible trimming to avoid rubbing at full lock or compression. Always verify the recommended size and pressure on the door-jamb label, and consult a professional for plus-sizing. After installation, cycle the steering and suspension to confirm clearance before you hit the trail.
Compare total installed cost, not just the tire price. Include mounting, balancing, TPMS service, and an alignment. Ask about current promotions or rebates, and consider bundle pricing with wheels or installation. Choose the correct size, load index, and speed rating for your vehicle and use case, then schedule regular rotations and alignments to extend tread life and keep the ride smooth.
The Toyo Open Country R/T Pro is a more aggressive and updated version of the original Toyo Open Country R/T. While both are hybrid rugged terrain tires designed to bridge the gap between all-terrain and mud-terrain performance, the R/T Pro features a tougher construction, deeper tread, and enhanced off-road capability. It’s built for drivers who need serious off-road durability while still maintaining decent on-road manners.
