Toyo's Open Country R/T Pro Brings 47 Rugged-Terrain Sizes, Up to 22 Inches

The rugged-terrain tire was invented for exactly the kind of truck that dominates a lifted meet: something that spends most of its life on pavement but needs to look, and work, like it could go anywhere. Toyo's Open Country R/T helped define that category. Now Toyo Tires has introduced the Open Country R/T Pro, which it positions as more aggressive than a conventional all-terrain, PASMAG reported on October 9, with the product page hosted on Toyo's Canadian site.

The headline numbers are size coverage and construction. There are 47 sizes for 17-, 18-, 20- and 22-inch wheels, and every one gets a three-ply polyester sidewall, two high-strength steel belts and jointless spiral cap plies.

What is different in the tread

The tread uses large shoulder lugs, wide lateral grooves and integrated stone ejectors, which is the formula that lets an R/T bite in loose dirt and throw rocks out before they drill into the casing. Full-depth siping is there for wet-road grip, and because it runs the full depth of the tread, it should keep working as the tire wears rather than disappearing halfway through its life.

Toyo also says the tread compound uses nanotechnology intended to improve tread life and reduce uneven wear. That claim matters on a lifted truck, where alignment is rarely perfect and big, heavy tires tend to cup and feather.

Why it matters for the lifted crowd

The 20- and 22-inch sizes are the tell. A huge share of lifted half-tons and HD trucks run 20s and 22s for looks, and those owners have historically had fewer aggressive options than the 17-inch off-road crowd. A three-ply sidewall across the range also means the R/T Pro should hold up to airing down and to the side hits that come with wide wheels and tight trails.
