Toyo Open Country A/T III Review, Features & All Terrain Performance (Canada Guide)
wet highways, gravel, cottage lanes, job sites, and the surprise snow day you didn’t plan for.
It’s designed to balance on road stability with off road traction, and it carries the 3PMSF severe snow symbol.
Category: All Terrain
Vehicles: Trucks / SUVs / Jeeps / CUVs
3PMSF: Yes
Studdable: No (most fitments)
Sizes: P/Euro, LT, Flotation
Durability: Stone ejectors
A/T III is made to be “one tire that does a lot.” It’s 3PMSF rated for snow traction, but it’s still not a dedicated winter tire for glare ice.
If you do daily icy commutes, a winter set can still be the safer play.
Quick Fit & Constraints (Choose the Right Open Country A/T III Setup Fast)
Use this checklist to confirm Toyo Open Country A/T III matches your truck/SUV, your load needs, and your terrain mix.
Most “A/T regret” comes from picking the wrong load type (P-metric vs LT) or expecting winter tire ice performance.
| Specs / Size | Start with your door jamb placard size (example: 265/70R17 or LT265/70R17). If your OE tire is LT, don’t “downgrade” to P-metric unless you understand the load/payload implications. |
|---|---|
| Compatibility / Load Range | Choose the correct Load Range (C/D/E) based on real use: towing, payload, job site duty, or mostly commuting. Higher load ranges are tougher, but they’re usually heavier and can ride firmer (and can affect fuel economy). |
| Season / Winter Reality | A/T III carries 3PMSF for severe snow traction, which helps for Canadian winter days. But glare ice is still winter tire territory. If your mornings are icy and steep, consider a dedicated winter set. |
| Use Case / Terrain | Best for a mixed life: highway + gravel + trails + work sites. • Mostly highway? You’ll care most about wet braking, stability, and noise. • Regular trails/rocks? You’ll care most about sidewall toughness and traction. A/T III is a “balanced” A/T—tough enough to explore, civilized enough to commute. |
| Budget / Value | Value = cost of ownership: tread life + puncture resistance + how much you benefit from durability versus weight/noise trade offs. If you’re 95% pavement, a milder A/T or highway tire may cost less long term. |
| Logistics / Ownership | Install as a full set of four for balanced traction. Free shipping + 1–3 business days |
Not sure? Send us your vehicle + tire size + whether you tow/carry loads and we’ll confirm the correct spec (P vs LT, load range, and fitment).
Performance Scorecard (Quick Buyer Snapshot)
| Category | Score (0–10) | What to Expect |
|---|---|---|
| Wet traction / wet stability | 8.4 | Designed with a strong wet focus for an all terrain; many drivers describe confident rain behaviour. |
| Snow traction (3PMSF) | 8.2 | Severe snow rated; generally solid snow confidence for an A/T category tire. |
| Ice behaviour | 6.0 | Typical A/T reality: better than non 3PMSF all terrains in snow, but not a winter tire replacement on glare ice. |
| Off road traction (dirt/gravel) | 8.3 | Strong mixed terrain capability for trails, gravel roads, and work sites. |
| Durability / chip resistance | 8.4 | Stone ejecting blocks help reduce stone drilling; built for toughness. |
| Comfort / ride quality | 8.1 | Often described as smooth for an A/T tire—especially compared to more aggressive A/T or M/T options. |
| Noise | 7.7 | Generally quiet “for the category,” though noise depends on size, load range, and road surface. |
| Value | 8.0 | Strong pick if you want one tire that can handle real mixed use without feeling like a mud tire on road. |
Scores reflect all terrain design intent plus aggregated owner sentiment themes (ride comfort, noise “for A/T,” and wet/snow confidence).
What the Toyo Open Country A/T III Is
- Type: Off road all terrain tire for trucks, SUVs, and crossovers.

Key Features & Technology (Buyer Friendly)
3PMSF severe snow rating
What it does: indicates the tire meets severe snow performance requirements.
Why you care: better snow confidence than non rated A/T tires—useful for Canadian shoulder seasons and winter days.
Stone ejecting blocks (durability)
What it does: helps eject stones from the grooves.
Why you care: reduces stone drilling and helps protect the casing on gravel and rocky roads.
Balanced A/T tread design (on road manners)
What it does: aims for stable handling and predictable steering on pavement.
Why you care: you get all terrain capability without living with full mud tire noise/feel.
Wet performance focus (rain confidence)
What it does: tread and compound choices are tuned to improve wet traction for the category.
Why you care: wet highways are where a lot of A/T tires feel sketchy—this design targets that.
Real World Performance Breakdown
Wet Roads (rain)
- Confidence: commonly described as stable and predictable in rain for an all terrain.
- Hydroplaning resistance: many owners report good highway rain behaviour when properly inflated.
Snow
- Traction: 3PMSF rating supports better snow performance than many non rated A/T tires.
- Reality check: snow traction ≠ ice braking—drive accordingly on polished ice.
Off Road (dirt/gravel/trails)
- Grip: strong mixed terrain capability for gravel, cottage roads, and light to moderate trails.
- Durability: stone ejectors help reduce stone drilling on rocky surfaces.
Dry Roads + Highway
- Handling: designed to be responsive and predictable for an A/T tire.
- Ride feel: typically smoother than very aggressive A/T or mud terrain tires.
Noise & Comfort
- Noise: often called “quiet for an all terrain,” but LT/E load sizes can sound more aggressive.
- Comfort: widely reported as comfortable, especially compared to chunkier A/T patterns.
Specs & Warranty (Canada First)
| Season / Category | All Terrain with 3PMSF severe snow rating |
|---|---|
| Vehicle types | Trucks / SUVs / Jeeps / Crossovers |
| Studdable | No (most fitments) |
| Size types | P/Euro Metric, LT Metric, Flotation |
| Mileage / treadwear warranty (Canada) | Up to 100,000 km on many P-metric sizes and 80,000 km on LT/Flotation sizes (program terms vary by exact size and market materials). |
Tip: all terrain tires live or die by rotations and alignment. Rotate every 8,000–10,000 km and keep pressures correct—especially on LT tires.
