Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tires shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.

Mickey Thompson Baja Boss AT

Drivers rate the Mickey Thompson Baja Boss AT very highly, praising it as a standout all-terrain that delivers near mud-terrain-like capability in mud and rocks while remaining well-mannered on-road. Reviews consistently highlight strong traction across wet roads, rain, snow, ice, and mixed off-road terrain, with handling and ride comfort described as better than expected for such an aggressive tread. Treadwear is also frequently noted as excellent, with some users reporting long life and even wear after high mileage.
- Excellent off-road traction (mud, rocks, dirt, sand)
- Strong wet-weather grip and hydroplaning resistance
- Very good snow/ice performance for an all-terrain (3PMSF capability)
- Surprisingly good on-road handling, comfort, and manners for an aggressive AT

All 8 Baja Boss AT reviewsHave had KO2, Toyo AT3, Yokohama MT tires for comparison.
We drive mostly highway, tow a 6k trailer, weekends are off pavement.
Initial impressions-
Expect fuel economy loss. These are heavy tires for an AT. We had these on a 2” lifted 22’ 4Runner- just awful fuel economy. Now have these on a 26’ Diesel half ton. The new truck also took a hit in fuel economy.
Great on road, incredible off-road, great on gravel, stable towing tire. Best tire I’ve been on yet and will definitely buy them again.
Toyo Open Country AT III
- 81%from 10 reviews

- 349,000 milesdriven by reviewers
Most drivers report the Toyo Open Country AT III as a strong all-around all-terrain tire, praised for confident handling and traction on dirt, snow and wet roads, with several high-scoring reviews highlighting long service life and even wear. Noise is generally described as low to moderate for an A/T, though a minority report noticeable noise and reduced responsiveness. The most consistent downside across lower/mid-scoring reviews is faster-than-expected tread wear compared with key competitors.
- Strong all-around capability on-road and off-road
- Good winter/snow traction for an all-terrain tire
- Good wet performance/hydroplane resistance
- Stable handling and confidence (towing and cornering)
- Tread wear/longevity concerns compared to competitors
- Some reports of increased road noise
- Slightly reduced responsiveness/comfort (stiffer feel)

All 10 Open Country AT III reviewsReally impressed with theses tires. Bought the LT version of the tires because I tow a 6k lbs trailer around all summer. The ride is stiff but the handling is amazing, no more Rolly Polly when changing lanes or sweeping turns! Live in Ontario so get a lot of snow, they handle really well and even aired them down to go down my favorite hunting trail in 7-8 inches of powder. Have had them when rock crawling in places I shouldn't have been with a stock GMC AT4 and they have never met me down. Best thing is after 75k miles with 40k towing a trailer I still have about half of the tread depth left.

Reading the results
Written from the test results and owner reviews above. It is analysis, not a measurement: where it and the tables disagree, the tables are right.
Pitting two popular all-terrain, all-season 4x4 choices head-to-head, the Mickey-Thompson Baja Boss AT and Toyo Open Country AT III target the same buyer but take different routes to performance. Across two 2025 tests in 265/70 R17, the Baja Boss AT consistently finished higher (2nd of 6 in a winter-focused test and 3rd of 9 at Tire Rack), while the Toyo landed just behind (3rd/6 and 7th/9).
In winter metrics the Mickey-Thompson leans on strong objective grip-shorter snow and ice braking and quicker snow handling-whereas the Toyo trades some braking for traction and predictability, feeling easier and more rounded to drive. On-road, Toyo posts better instrumented wet and dry stopping and lap times, but the Baja Boss counters with superior subjective wet feel, comfort, and markedly lower noise.
Conclusion
If you want the broader, more forgiving performer, the Mickey-Thompson Baja Boss AT is the safer bet. It combined excellent winter braking/handling with well-balanced road manners, winning both shared tests overall while avoiding major weaknesses. Its quieter ride and better subjective wet confidence make it easy to live with daily, especially in mixed climates that see real winter.
Choose the Toyo Open Country AT III if you prioritize objective on-road metrics-shorter dry and notably shorter wet braking, plus tidy wet/dry handling-with a predictable, trustworthy character at the limit. Just be ready for a stiffer ride and higher noise, and slightly longer winter stopping. Bottom line: Baja Boss AT for all-weather grip and refinement; Open Country AT III for drivers who value tested on-road stopping and a steady, confidence-inspiring feel.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tires ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tire Reviews Score rates each tire out of 10 from every independent test result and vetted owner review we hold, so two tires can be compared even before a test has run them together.
Who does the testing
Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
