Toyo Open Country R/T Pro LT285/75R17
The LT285/75R17 is one of the most trusted and widely used super-duty truck tire sizes in America, and the Toyo Open Country R/T Pro in this fitment delivers the rugged-terrain performance that F-250, RAM 2500, and Silverado 2500HD owners have been waiting for. Factory-fitted on many super-duty trucks, this 33.8-inch tire slots right in with no lift required and no modifications needed, while the R/T hybrid tread pattern delivers dramatically improved off-road grip over stock all-season tires. The tall 75-series sidewall is particularly valuable for off-road use — whether you're airing down for rock crawling or absorbing trail impacts at speed. Dual load ratings (128/125Q) support both single and dual-rear-wheel configurations. This is the tire for buyers who want true off-road performance on their work truck without changing a single other component.
Overview
The Open Country R/T Pro LT285/75R17 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 LT285/75R17: 285mm (~11.2") wide, 75% aspect ratio, 17" rim. Approximately 33.8" overall diameter. A classic super-duty truck size — one of the most common factory fitments on Ford F-250, RAM 2500, and Silverado 2500HD. The tall sidewall is ideal for off-road traction and aired-down performance. On pavement, the LT285/75R17 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 factory replacement on super-duty trucks, work truck duty cycle, overlanding with towing capability, towing-first buyers wanting off-road tread upgrade from stock all-season, and carries a 128/125Q load rating for dependable performance under demanding conditions.

On‑Road and Off‑Road Performance
On pavement, the LT285/75R17 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 LT285/75R17 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 factory replacement on super-duty trucks, work truck duty cycle, overlanding with towing capability, towing-first buyers wanting off-road tread upgrade from stock all-season.

Open Country R/T Pro LT285/75R17 vs Alternatives
In the LT285/75R17 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 LT285/75R18, LT295/70R17, LT275/70R18 — neighboring super-duty sizes on 17" and 18" rims.
