Toyo Open Country C/T 10,000 Mile Review

Toyo C/T 10,000 mile report

When the Toyo Open Country C/T was initially introduced it was only available in Canada. A few years ago, when that changed, it moved to the top of my must try list. Commercial traction or hybrid designs are my favorite type of tread, and the C/T might be the best, slowest-wearing design I’ve used on any truck in several years; maybe ever.

The Toyo C/T has the severe snow, mountain snowflake rating.

Mount, balance, and tracking

Because the Open Country C/T is an on/off-road commercial-grade tire, there are fewer sizes offered than other Toyos like the Toyo A/ T II. However, there are still six 16-inch, seven 17-inch, five 18-inch, and seven 20-inch sizes available.

For this evaluation I mounted 35×12.50R17 on forged aluminum OEM Ram Power Wagon wheels. They required very little weight to balance, typical for Toyos, and ran smoothly down the highway at all speeds.

104-pounds on OEM 17″ forged aluminum Power Wagon wheel, needing only 1.25 ounces for a static balance.

Initially mounted my 2014 crew cab, which has an SPC offset right ball joint to counteract treads that pull to the right, the C/T would drift just slightly to the left after a few seconds with no hands on the steering wheel, depending on the road crown. (To be perfectly clear, this is because of the offset ball joint and caster settings, not a characteristic of the tires, the C/T does not appear to pull right or left, they are neutral.) On the 2017 Ram 2500 regular cab with Hallmark flatbed camper, the C/T track perfectly straight for several seconds on flat roadways. They were a great match for the outfit, and where I decided to keep them for this evaluation.

Almost all the miles logged have been with this 2017 Ram 2500 Hallmark flatbed camper outfit.

General traction and performance

The C/Ts saw a little of most terrains, including snow, packed dirt, gravel, rock and plenty of pavement. Deep off-highway mud, snow, and deep sand were not experienced; a 10,000-pound camper outfit is less happy on these surfaces, so I only drive on them when necessary. However, with the good void-ratio and siping this tread offers, I’m confident the C/T would perform as well or better than similar commercial-traction designs.

Many modern tires perform well in moderate on-highway or off-highway snow, and this was true with the C/T. However, the mountain snowflake severe winter rating provides extra assurance in wet conditions, and I would pick the C/T over many hybrid or all-terrain designs for winter service. Obviously they are unlikely to perform as well as a dedicated winter tire, but those designs are less versatile on heavily-loaded trucks and rarely offered in larger sizes.

The Open Country C/T is quiet for the void it offers, and no louder than the Toyo R/T or A/T II Xtreme with which I am familiar in similar sizes. I’ve recommended the C/T to many of my readers, including a professional photographer and adventurer who lives in Jackson, Wyoming. He has been impressed with their snow capabilities. Another guy lives full-time in his heavy truck camper and uses them.

Wear close-ups 

You can see a small amount the feathering on the outer lug sipes. For nearly 6,000 miles without a rotation, this minor visible wear was impressive and not concerning. Appropriate rotations will true-up the tread.

Slow and even wear, 6,000 miles since the last rotation, most of it on highways.

Phenomenal Longevity

As my video assessment and testimonial enthusiastically shares, I am most impressed with the slow rate-of-wear on these Toyo Open Country C/T, better than any other tread in years, maybe ever.

17/32″ of tread depth remaining after 10,000 miles!

The 4,400 miles per 1/32 of depth is exceptional, particularly for such a heavily-loaded, diesel, truck camper outfit. Was the slow treadwear due to a higher than typical percentage of highway miles? Possibly, although my outfit is not a daily driver and routinely sees many more long-distance travel miles than city driving. Double the mileage of most tires I’ve run on diesel trucks, and still 50-percent more than other standouts is nothing short of phenomenal!

Absolutely love these Toyo C/T tires and would like to try them in a 295/65R20 size.

The C/Ts were removed from service only to begin another review, but I’d like to run them again soon, preferably in an 18-inch or 20-inch size with a higher load-index that’s better suited to my heavy camper. The 35×12.50R17 was chosen because I wanted a 35-inch size, and I already had the wheels. At the time I was adamantly against 20-inch tires because the shorter sidewalls offer less flex off-pavement. Though shorter, less flexible sidewalls can be a huge a positive for overall camper stability and handling. My opinion has softened, as long as the tire is tall enough that there’s adequate sidewall.

Toyo Open Country R/T Diesel Wear Review

One of the first camping trips with the new R/Ts where they saw light dirt, rocks, a little mud, and much low psi crawling.

Toyo Open Country R/T Tires

Toyo Tires’ rugged terrain R/T got the nod to be the first traction tread on my 2017 Ram regular cab. The versatility of a 60/40 design is ideal for my many miles both on- and off-highway. The R/T has had my attention since its introduction, but there was extra allure once it was offered in my favorite, niche, 18-inch size, the 285/75R18. Hearsay reports indicated that it was extremely quiet on-road, but I needed to experience this for myself.

Toyo’s Rugged Terrain R/T

Features And Benefits include:

-High Turn-Up, 3-Ply Polyester Sidewall Construction: Contributes to excellent durability, impact resistance, and handling.

-Optimized Pattern Arrangement: Reduces noise for improved driving comfort.

-Aggressive Sidewall Designs With Durable Sidewall Compound: Enhances traction and side impact protection and offers two slightly different sidewall tread designs for owner preference.

-Open, Scalloped Shoulder Blocks: Improves off-road traction; enhances grip in muddy, sandy, or snowy off-road conditions; and ejects mud and snow through the open channels.

-Stone And Mud Ejectors: Forces stones and mud from the grooves.

The R/T offers a choice of sidewall shoulder tread design.

Mount, Balance, and Baseline

Five tires were ordered to ensure I had a spare that was not only the proper size but also offered adequate traction, which can be important when the spare is needed in difficult terrain. The new rubber balanced without drama on OEM aluminum wheels, typical for Toyo’s multi-segment designs.

One would think that the R/T’s outer lugs would lead to more noise compared to the familiar A/T II Xtreme. My initial run on the R/Ts had me thinking they were maybe slightly louder. However, when I put the A/T II Xtremes back on, and drove over the same section of freeway, I could not tell a difference. My back-to-back evaluations corroborated other reports that say the R/T is extremely quiet and sometimes indistinguishable from the A/T II Xtreme. Quite an engineering accomplishment! At most there may be a slightly different pitch to the noise they make and how they sound at lower speeds. To be perfectly clear, the R/T is not a silent tread design—get a highway tire if you want that—but they are impressively quiet for their appearance, void, and target audience.

Toyo A/T II Xtreme on the left, and Toyo R/T on the right. Both are LT285/75R18E and can support 4,080-lbs each at 80 psi.

Because I am a stickler for drivability, I was happy to discover that the Toyo R/T construction and design mated perfectly to my 2017 Pack Mule, which still sports the factory caster and camber settings; only the toe has been adjusted. There were no unusual handling or tracking quirks that required me to seek alignment or suspension adjustments. On level and smooth roadways no steering input correction was necessary. The truck continued straight and remained neutral, even when I played the old game: look mom, no-hands.

Some treads and chassis, even identical sizes from the same manufacturer, mesh differently. It is worth noting that the same size Toyo A/T II Xtreme drift to the right a bit on the ’17 Mule, yet they track perfectly straight on the 2014 Carryall crew cab that sports an SPC offset ball joint.

The guys at the tire shop must hate seeing me drive up.

Static, single-plane spin balancing in my preference.

Nearly 100 lbs of Toyo traction tire and OEM forged aluminum wheel needed a mere 3-ounces.

General Use And Wear Data

Over several months these Rugged Terrain treads saw at least a little of most surfaces. That means much pavement, but also plenty of dirt, gravel, snow, slush, and a little ice. The R/T is not a dedicated winter tire. It does okay, though maybe not quite as good as the familiar Toyo A/T II, which offers much more siping. The R/Ts have spent as little time as possible crossing mud…I don’t care for it, and heavy trucks and campers often flounder in mud.

Modern turbo-diesel pickups (not just Rams) often wear tread quickly compared to their gas-powered cousins. This has much to do with the massive amount of twist that the engines apply to the ground, and in this case the ‘Mule’s constant GVWR load. Manual transmissions are compounding factors, and both my Fourth Generation Ram/Cummins 2500s have the G56 6-speed (which I love). My driving style is generally smooth and efficient; however, there are times when I intentionally smash the accelerator, run the Cummins up-to the redline, and/or drive at higher speeds for hours. Therefore my tire wear data may represent a slightly fast wear scenario.

34.84-inches tall inflated according to Toyo, and about what I measured.

All LT-metric R/T sizes come with 16.4/32” of tread depth. This is 0.6” less than the same size Toyo A/T II, and the starting depth affects how many miles one might get out of tires before needing replacements. I prefer more rubber for both traction and longevity, but the 16.4/32” seems to be just enough. All floatation sizes start with 18.9/32-inches. Over 8,650 miles, rotating four, using a rearward cross pattern, these 285/75R18 Toyo R/T have delivered 1,965 miles per 1/32” of tread. This is similar to other tires that have yielded up to 2,100 miles per thirty-second. Wear often slows down as tread becomes shallower (if tires are rotated), and the measurements become more accurate as well.

Recently I mounted a different set of meats for a new evaluation, but the R/Ts remain in my shop mounted, balanced, and ready for continued use. Tire prices vary throughout North America, but in my part of the West the LT285/75R18E Toyo R/T are $340 each at my local Discount Tire.

Toyo Tires C/T Tracking Review

Toyo C/T 35×12.50R17 update.

The tries track straight and true on my built 2017 Ram 2500 Hallmark Camper project; even after a recent front suspension modification that yielded 2.75-inches of lift.

Excellent drivability is not just desirable, I demand it from my vehicles. If my rigs don’t drive well there may have been a change or failure during the build that needs correcting.
