TIRE INFO
The Arroyo Tamarock R/T 35×12.50R20 is a rugged-terrain workhorse built for enthusiasts demanding off-road power without highway compromise. Its 125Q load-and-speed rating and 12-ply F-rated structure equip it with a massive 3,640 lb load capacity, making it suitable for towing, heavy cargo, and robust overlanding setups.
Its aggressive tread—nearly 19/32″ deep—utilizes zig-zag grooves, staggered shoulders, and stone ejectors to offer strong grip in mud, sand, and rocky trails. Plus, the tall sidewall lugs extend traction onto the tire flank when aired down. Yet unlike a full mud-terrain tire, its central block layout and pitch engineering provide smoother, quieter highway performance
Available in dual-sidewall styles—including bold red-lettering—this tire also stands out visually for lifted trucks and adventure builds. Built with a silica-enriched compound, it delivers decent wet traction.
Performance feedback leans positive: many users appreciate the surprisingly quiet ride for such a rugged tire, while others praise its longevity—some reporting over 25,000–50,000 miles of usage . Minor concerns include slight noise levels and less-than-top-tier deep snow grip, common among rugged terrain hybrids .
To support long-term value, Arroyo offers a 40,000–55,000 mile treadwear warranty, depending on retailer—plus confidence in durability for on- and off-road use
The Tamarock R/T 35×12.50R20 excels for those seeking a rugged, load-ready tire that wears quietly and performs strongly both off the beaten path and on asphalt. With a strong warranty and dual sidewall options, it presents impressive form, function, and value—perfect for ATV trucks, overlanders, and daily-driven off-road rigs.
