Toyo Open Country A/T III Review

Toyo’s most versatile tire has just been updated with with more capability than ever before. Always an all-terrain tire to consider, Toyo just made the Open Country A/T III a practical must-buy for anyone who loves or needs to go off-road.

PROS

• Even more off-road grip
• Now with true winter capability
• Better wet weather grip

CONS

• Slightly less responsive highway feel
• Slightly more expensive than the A/T II

At first glance it’s obvious that this is a very different tire from its predecessor. The A/T II had a conventional street-tire tread pattern layout with five circumferential lines of tread blocks going around the tire. Now with the A/T III that’s been changed so the interior three tread segments are interwoven.

The result of this design is vastly superior off-road grip, coming more in line with mud-terrain tires thanks to more biting edges and more void between the tread blocks. Importantly, there’s not only more void, but it’s distributed more evenly too – for better grip and wear.

There isn’t any real increase in siping here, but due to the overall compound used and the new tread pattern, the A/T III is now certified with the three peak mountain snowflake logo, meaning it’s a truly capable tire for winter weather – something the A/T IIs always lacked. And as the 3PMS logo becomes the norm amongst all-terrain tires, this is a critical benefit.

Important features that carry over from the AT II include stone ejectors built into the base of the tread between the exterior tread blocks, to help remove stones and prevent against premature tire wear. The exterior tread lugs are also staggered to help dig in to soft surfaces.

Also important to note is the new tread compound, which is designed to deliver better on-road grip in both the wet and dry, while also managing to be more durable against cuts and chips – allowing the tire to maintain its grip for  long time.

And speaking of long times, Toyo has retained the A/T II’s top notch milage warranty.

Looking at on-road performance, the new design is both quiet and comfortable although it is slightly less responsive to steering inputs on the highway due to that lack of a center tread rib.

Overall, Toyo took the AT II and pushed it much further into the off-road space, adding significantly improved off-road performance, with only slight drawbacks when it comes to the street.

Toyo Open Country A/T III Pricing

Pricing for the Toyo Open Country A/T III has gone up slightly compared to the AT II which started at around $120 per tire. The A/T III starts at $140 and goes up to approximately $385 per tire.

Toyo Open Country A/T III Warranty

Toyo backs the new Open Country A/T III with a 65,000 mile treadwear warranty for p-metric sizes and a 50,000 mile warranty for LT versions.

There’s also a 45-day / 500 mile money-back guarantee.

Plus, the tires come with Toyo’s limited warranty, guaranteeing the materials and workmanship are free from defects for the first 5 years. That includes free replacement for the first 25 percent of wear and a prorated amount is offered for the remaining tread, down to the last 2/32nds.

How Long do Toyo Open Country AT Last?

A simple question with a surprisingly simple answer. The new Toyo Open Country A/T II tires are guaranteed for at least 65,000 miles of use both on and off-road. That’s for p-metric sizes. If you step up to the LT sized for HD trucks, Toyo puts a 50,000 mile warranty on the tires.

Toyo Open Country AT2 vs AT3

So what’s the difference between the Toyo Open Country AT2 and AT3? In short, the new AT3 is a more extreme off-road tire. Rather than the five tread rows it just two external or shoulder tread block sections and an inner section of treads that are intertwined. This makes for a less refined and responsive tire on the highway, but offers superior grip off-road. The new tread pattern and compound also resists freezer better, so the AT3 is certified for true winter use.
