Tire A

Toyo Observe G3-Ice

We haven't collected enough community discussion about this tire yet.

Tire B

Toyo Open Country A/T III

Positive

Community feedback for the Toyo Open Country A/T III is largely positive, with drivers frequently praising its traction in snow, rain, and off-road conditions, as well as its smooth ride comfort and solid tread life. While road noise and heavy unsprung weight are noted by some users, the primary complaints involve sidewall durability issues specifically on C-load ratings compared to E-load versions, alongside a recent product recall.

“I have them on my Tacoma. For what I do with that truck I like them. But I don't think I'd like them as much on the Ford. I needed tires for both trucks within a month of each other and went with Toyo AT III's on the F150. I think I put the right tire on the right truck The Goodyears are a bit more aggressive, a bit louder, and don't ride quite as well. The old Tacoma is mosty used locally and is my hunting truck so those tires match the needs better. Toyo Tire Open Country A/T III | Discount Tire”

“Appreciate you asking the question and why not just swap out for the Toyo Open Country A/T III with the 3MPSF rating right before you make the drive? I've run dedicated winter tires for years now and would not consider them useable at a 7/32 tread level. Hope you have a great time in CO and enjoy the road trip!”

“1 year, +/- 20k miles since swapping to Toyo Tire Open Country A/T III 215 /75 R15 w DX4's Pocket 15 X7 wouldn't change a thing. 80% commuting, 20% fun. Soak up the potholes and dig in the snow. Softest, smoothest”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
