Toyo Open Country R/T Pro LT255/80R17
For super-duty truck owners who need maximum load capacity in a narrow, tall tire package, the Toyo Open Country R/T Pro LT255/80R17 delivers. The impressive 80-series aspect ratio gives this tire one of the deepest sidewalls in its class — providing outstanding trail compliance, excellent aired-down off-road performance, and significant protection against sidewall damage in rocky terrain. At approximately 33.1 inches in diameter, this tire is compatible with many Ford F-250, RAM 2500, and Silverado 2500HD configurations. Dual load ratings (123/120Q) support single and dual-rear-wheel setups common on work trucks and expedition rigs. The rugged-terrain tread pattern handles rough job site roads, forest service routes, and off-road trails equally well. This is the tire for drivers who prioritize capability and durability above all else.
Overview
The Open Country R/T Pro LT255/80R17 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 LT255/80R17: 255mm (~10.0") wide, 80% aspect ratio, 17" rim. Approximately 33.1" overall diameter. A narrow, tall tire with one of the deepest sidewalls available in this size class. Preferred for work trucks, towing rigs, and off-road vehicles needing high load capacity with excellent trail compliance. On pavement, the LT255/80R17 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 work truck duty cycles on unpaved roads, super-duty towing with off-road capability, narrow-platform trucks needing clearance, fleet applications requiring high load rating, and carries a 123/120Q load rating for dependable performance under demanding conditions.

On‑Road and Off‑Road Performance
On pavement, the LT255/80R17 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 LT255/80R17 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 work truck duty cycles on unpaved roads, super-duty towing with off-road capability, narrow-platform trucks needing clearance, fleet applications requiring high load rating.
Fitment & Compatibility
Trucks: Ford F-250 Super Duty (stock/upgrade), RAM 2500, Chevrolet Silverado 2500HD, Ford F-350 (some configs)
SUVs: Toyota Land Cruiser (older), Land Rover Defender (older), Nissan Patrol
Off-Road & Specialty Vehicles: Overland expedition rigs requiring narrow clearance, super-duty work trucks on forest roads, towing rigs that also trail ride
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 LT255/80R17 with a load rating of 123/120Q (Load Range E). This rating makes it suitable for heavy towing and payload demands on super-duty platforms, though always verify that load index meets or exceeds your vehicle's minimum requirements, especially if you tow or carry heavy payloads regularly.
Pricing & Value
Pricing for the LT255/80R17 size reflects its Load Range E construction and rugged-terrain capability. Installed cost includes mounting, balancing, TPMS service, and alignment. Look at total ownership value — including durability on rough roads, balanced on-road manners, and dependable trail traction — when comparing against alternatives. Regular rotations, proper inflation, and periodic alignments extend tread life and maximize your investment.
Open Country R/T Pro LT255/80R17 vs Alternatives
In the LT255/80R17 size category, the Open Country R/T Pro competes with aggressive all-terrains like the BFGoodrich All-Terrain T/A KO2 and Falken Wildpeak AT3W, typically offering a more open lug pattern for added loose-surface bite. Compared with other rugged-terrain hybrids such as the Nitto Ridge Grappler or Goodyear Wrangler Duratrac, the R/T Pro emphasizes durability and off-road traction while keeping composed on-road manners. Related sizes worth comparing include LT285/75R17, LT295/70R17, LT265/70R17 — neighboring 17-inch options varying in width. The best choice depends on your priorities — maximum trail capability or quieter daily comfort.
