Our verdict on the Toyo Open Country A/T III
Foul-weather traction is what the Toyo Open Country A/T III's profile leads with — snow traction at 9/10 and tread life at 9/10 — against an 8.1/10 blended score for an all-terrain. Nothing in the profile collapses: the lowest mark, mud clearing at 5/10, is 4 points off the top and does not even feed the blend, and the dataset flags it when the budget is tight. It carries the 3PMSF severe-snow symbol, sits in the premium-tier bracket at #4 of 50 overall and 3rd of 18 all-terrains, is catalogued in 11 Tacoma sizes on 16- through 18-inch wheels, and rests on 3 cited sources. Its lead use cases are a balanced all-terrain setup and snow driving, one place behind the Falken Wildpeak A/T4W in our ranking.

| Axis | What it covers | Score | In blend |
|---|---|---|---|
| Road comfort | pavement ride quality and noise | 8/10 | Yes |
| Wet grip | traction on wet pavement | 8/10 | Yes |
| Snow | packed snow and winter road traction | 9/10 | Yes |
| Trail | dirt, gravel, and rock trail traction | 8/10 | Yes |
| Mud | deep mud traction and self-cleaning | 5/10 | No |
| Durability | puncture and sidewall resistance | 8/10 | Yes |
| Tread life | expected mileage before replacement | 9/10 | Yes |
| Efficiency | weight and rolling resistance | 6/10 | No |
| Looks | how aggressive the tread and sidewall read | 7/10 | No |
| Value | what the tire delivers per dollar | 7/10 | 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 A/T III but sit outside it, which is why a mud or looks score can run well above or below the headline.

Tacoma sizes the Toyo Open Country A/T III comes in
The catalog behind this dataset records the Toyo Open Country A/T III in 11 sizes that fit common Tacoma wheel diameters, spanning 16-inch, 17-inch, and 18-inch wheels. Of those, 10 have a Tacoma fitment page on this site, linked below.
Those 11 entries are the dataset's own availability list for the Toyo Open Country A/T III, 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.

Toyo Open Country A/T III on a Tacoma: common questions
In our editorial synthesis the Toyo Open Country A/T III blends to 8.1/10 across the seven all-round axes, which places it 3rd of 18 all-terrains and #4 of 50 in the whole research set. Its case rests on snow traction (9/10) and tread life (9/10), so it suits a balanced all-terrain setup, snow driving, and a daily driver that sees trails.
The research catalog records the Toyo Open Country A/T III as offered in 11 sizes that fit common Tacoma wheel diameters: 265/75R16, 285/75R16, 265/70R17, 275/70R17, 285/70R17, 255/80R17, 285/75R17, 265/70R18, 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 A/T III carries the 3PMSF severe-snow-service symbol, and our synthesis puts its snow axis at 9/10. That combination is what qualifies it as a year-round tire in states with severe-snow tire rules, though a dedicated winter tire still out-grips any all-season or all-terrain on ice.
The weakest marks in the Toyo Open Country A/T III's profile are mud clearing at 5/10 and rolling efficiency at 6/10. The dataset flags it as the wrong choice when the budget is tight and you need maximum mud traction. Those judgements come from the 3 cited sources listed on this page, not from anything measured here.
