Our verdict on the Toyo Open Country M/T
Mud clearing is where the Toyo Open Country M/T maxes out at 10/10, and with sidewall and carcass toughness at 10/10 the mud-terrain lands on a 5.7/10 seven-axis blend. That shape is a specialist's: rolling efficiency bottoms out at 2/10 and snow traction sits at 3/10 — an 8-point gap the headline number never sees, since neither axis feeds it, and the dataset flags it when quiet daily driving is the priority. It stops at the M+S marking rather than the 3PMSF symbol; as a premium-tier option it sits at #28 of 50 overall and 2nd of 9 mud-terrains, is catalogued in 10 Tacoma sizes on 16- through 18-inch wheels, and rests on 4 cited sources. Its lead use cases are mud and trail work and rock trails, one place behind the BFGoodrich Mud-Terrain T/A KM3 in our ranking.
The ten-axis score profile
Every model in the research set is rated 0-10 on the same ten axes. For the Toyo Open Country M/T the profile runs from 10/10 on mud down to 2/10 on efficiency; the 5.7/10 headline figure is the average of the seven axes marked below as feeding the blend.

| Axis | What it covers | Score | In blend |
|---|---|---|---|
| Road comfort | pavement ride quality and noise | 3/10 | Yes |
| Wet grip | traction on wet pavement | 5/10 | Yes |
| Snow | packed snow and winter road traction | 3/10 | Yes |

| Mud | deep mud traction and self-cleaning | 10/10 | No |
| Durability | puncture and sidewall resistance | 10/10 | Yes |
| Tread life | expected mileage before replacement | 5/10 | Yes |
| Efficiency | weight and rolling resistance | 2/10 | No |
| Looks | how aggressive the tread and sidewall read | 10/10 | No |
| Value | what the tire delivers per dollar | 5/10 | Yes |
7 of the ten axes feed the blended number (road comfort, wet grip, snow, trail, durability, tread life, and value); mud, efficiency, and looks are shown for the Toyo Open Country M/T but sit outside it, which is why a mud or looks score can run well above or below the headline.

- Rock trails — durability 10/10.
- Sidewall durability — durability 10/10.
- An aggressive look — looks 10/10.
Avoid if
The same dataset flags where the Toyo Open Country M/T is the wrong pick, again with the axis behind each call.
- Quiet daily driving is the priority — road comfort 3/10.
- Snow traction is the priority — snow 3/10.
- Fuel economy is the priority — efficiency 2/10.
Tacoma sizes the Toyo Open Country M/T comes in
The catalog behind this dataset records the Toyo Open Country M/T in 10 sizes that fit common Tacoma wheel diameters, spanning 16-inch, 17-inch, and 18-inch wheels. Of those, 8 have a Tacoma fitment page on this site, linked below.
Those 10 entries are the dataset's own availability list for the Toyo Open Country M/T, not a live retailer feed — a model with a thin catalog gets a short list here rather than a padded one. What actually clears on your truck still depends on wheel width, offset, and how much trimming you will accept, so check the size against your generation before you buy.
Sources behind the Toyo Open Country M/T's scores
The Toyo Open Country M/T's row rests on 4 of the 83 cited documents behind this research set — tacoma recommendation, tacoma owner setups, and manufacturer product. Each is listed with the date it was read.
Toyo Open Country M/T on a Tacoma: common questions
In our editorial synthesis the Toyo Open Country M/T blends to 5.7/10 across the seven all-round axes, which places it 2nd of 9 mud-terrains and #28 of 50 in the whole research set. Its case rests on mud clearing (10/10) and sidewall and carcass toughness (10/10), so it suits mud and trail work, rock trails, and sidewall durability.
The research catalog records the Toyo Open Country M/T as offered in 10 sizes that fit common Tacoma wheel diameters: 265/75R16, 285/75R16, 285/70R17, 33x12.5R17, 285/75R17, 315/70R17, 35x12.5R17, 275/70R18, 285/70R18, and 295/70R18. That is the dataset's own availability list rather than a live retailer feed, so confirm the exact size and load range with the seller before ordering.
The Toyo Open Country M/T carries the M+S marking but not the 3PMSF severe-snow symbol, and our synthesis scores its snow axis at 3/10. If your state or your commute requires a severe-snow-rated tire, this is not the row to pick.
The weakest marks in the Toyo Open Country M/T's profile are rolling efficiency at 2/10 and snow traction at 3/10. The dataset flags it as the wrong choice when quiet daily driving is the priority and snow traction is the priority. Those judgements come from the 4 cited sources listed on this page, not from anything measured here.
