Toyo’s light truck product line-up consists of 3 different names. Open Country, M-Line, and Proxes. While Open Country consists of 7 different products; others only have one each. Today, I will compare Toyo M55 with Open Country CT, MT, and AT. Though, the real competition will be between Open Country CT and Toyo M-55. Let’s see which one is better for your usage!
At a Glance
As a former Bridgestone engineer, from my standpoint, Toyo Open Country CT and Toyo M-55 are solid commercial tires. The only difference is they work under different circumstances. In this case, if you work under mild conditions (little dirt, mud, or snow), Toyo Open Country C/T is a better option for you. It also offers the most smooth ride among these. If you have a heavy-loaded application, need long tread life, and have huge traction you should definitely go with Toyo M-55.

Toyo M55 vs Open Country MT vs CT vs AT
Toyo’s Open Country line-up is met with different customer expectations.
- Toyo Open Country M/T: MT is a maximum traction tire. Hence, its limited tread life will not cover commercial intent.
- Toyo Open Country C/T: CT is a commercial-grade tire. Yet, it has limited traction ability compared to MT.
- Toyo Open Country AT: AT is on-road tires that have off-road manners. Comfort is one of its priorities.
Now, I would like to talk about M55 a bit. M55 is a combination of MT and CT. While it can provide maximum traction, it also has a satisfying tread life. It is gold for individuals, small, even massive businesses. I will not put AT to the rest of the comparison. These have completely different intents. If you want to see where AT places between Open Country’s, you can check this article!
Let’s start with the tread depth.
Toyo Open Country MT has the deepest tread depth between these three. Tread depths for the size of LT255/85R16,
- Toyo Open Country MT: 18.9mm
- Toyo M-Line M55: 18.1mm
- Toyo Open Country CT: Not available but tread depths are the same with M55
Tread depth can help to traction. Though, it is also strongly related to compound and tread design.
MT has the most aggressive tread design among them. It has wider shoulders and bigger lugs that are going to help it a lot on severe off-road surfaces. Yet, inadequate sipes are kinda prof of poor wet traction.
CT and M-55 have similar patterns. The sharpest difference is the sidewall. M-55 has flat and stiff sidewalls. It is designed to work under heavy loads. So, stiff sidewalls are a must. These are not the tire for air-down driving. Pay attention to this.
If you need low inflation pressure driving, you should go with MT or CT. In that case, your intent will be the decider. CT for commercials, MT for off-road cats.
Lastly, M-55 and CT are studdable tires of this comparison. They will perform better than others on the ice.
As we all expected, commercial-grade tires tend to last more than mud or all-terrains.
While CT and M-55 are getting 5-stars due to tread life, MT is getting 4 at maximum. If you will use them on the road too much, the star rating most probably will decrease to 3.
Getting maximum wear life from a tire is related to you as well as your tire,
If you’d like to learn how to get maximum tread life:
Normally, I evaluate durability with to resistance of the sidewall impacts. In that case, we are comparing commercial tires. So, sidewall impact is not your main concern.
M-55 has flat sidewalls. That might seem a bit weak at first sight. Wrong! These tires have the strongest sidewalls I have ever seen. Exceptional, definitely exceptional. May be as strong as 14-ply.
On the other hand, MT and CT have trustworthy sidewalls. These two also have sidewall protectors that M-55 does not even need.
Comfort and Noise
If you are looking for comfort and less road noise, you are at the wrong place. Let me guide you to the proper one!
If I have to choose one of them, I would definitely go with Toyo Open Country CT.
Surprisingly, M-55 is the loudest one. Even, MT has less road noise no matter how wide its void area is.
About comfort, I have talked about how stiff is M-55. It’s placed at the bottom again.
Toyo Open County CT is the true ruler in this section.
A side note here: Even though some tires tend to make noise because of their tread patterns, it’s still possible to keep your tire noise down.
I’m leaving a perfect explanation below from DiscountTire for those who need it;
How to Keep Tire Noise Down? –>
The off-road performance of these tires depends on different variables. In that case, I would like to evaluate them with two different approaches. Commercial and air-down.
While commercial off-road contains gravel and dirt performance; mud, rock, and sand will be regular off-road performance indicators.
- A side note here: If you’d like to see the best all-terrain tires by vehicle or usage, this article is GOOOOLD –> https://tireterrain.com/best-all-terrain-tires/
If you have are a commercial intended user, you are mostly facing gravel and dirt. These are the surfaces you need traction most.
All of our tires are very successful on these surfaces.
Nevertheless, well-placed sipes increase dirt traction a lot for CT and M-55. MT is not bad but not good as others.
Gravel is a bit cheeky. In that case, you should put groove width under the consideration. MT with the extensive grooves sometimes struggling on gravel depending on stone diameter. If the stones are too small, creating a biting age becomes a huge challenge. Well, you lose traction.
CT and M-55 do not have this problem. Stone holding is where these two separated. CT is holding a bit much more stone. These stones might cause damage in further time.
For the commercial off-road my ranking is,
Air-down situations are mud, rock, and sand. I will put M-55 out of this section. M-55’s sidewall is not usable for air-down conditions. It will crack if you will decrease your inflation pressure.
On rock, I like CT very much. It is not as good as MT. Yet, lugs are capable to move in different ways. That increases gripping ability significantly. On the other hand, MT’s rock performance is not questionable.
On the sand, softer designs always work better on the sand. So, CT is my pick.
On mud, no surprise. MT is a winner as a mud-terrain tire. Evacuation capability is exceptional.
Wet performance is where these tires place very closely. Either of them has its own advantages.
- Toyo Open Country MT: Soft compound
- Toyo Open Country CT: Normal compound, average siping
- Toyo M-55: Perfect siping
MT has a perfect compound for wet grounds. Yet, siping is not providing enough biting.
CT has the optimal design. Average siping and middling compound
M-55: Perfect siping, stiff compound
The battle is close. Yet,
Note: Hydroplaning is vital for a safe ride under the pouring rain. However, it might occur even with the best tire. Maybe you can’t prevent it but if you know what it is and how to deal with it, you can easily stay on the safe side.
Here is an extremely efficient guide about ‘How to Deal with Hydroplaning?‘ –> https://www.discounttire.com/learn/hydroplaning
It’s time to put MT aside. Winter is not MT’s priority. It has an average winter performance. But not rated with 3-peak mountain snowflake marking. It can not compete with M-55 and CT.
M-55 and CT both have 3-peak mountain snowflake marking. That means we are safe in harsh winters. Moreover, both are studdable. Frozen grounds will not be a problem anymore.
The only advantage CT has is compound toughness. A softer compound always works better on snow or ice.

- LT sizes have stronger sidewalls. That feature makes them more durable. Yet, these tires offer a rougher ride. (LT vs P-Metric tires)
- XL sizes tend to carry more load and offer better handling. Hence, if you’ll go with p-metric sizes, they might be a better pick for hauling and towing( XL vs SL tires)
- Please pay attention to the load range and speed index. These metrics are essential if you expect decent tread life
- There isn’t a bad tire in the market right now, you should just know what to expect from tires
