Toyo Open Country A/T III EV Tires Launched: Charge Up Your Adventure

[Discount Tire]

Toyo Tires has launched an all-new version of their Open Country A/T III, engineered specifically for EV trucks and SUVs. Building on their popular all-terrain tire, the Open Country A/T III EV aims to deliver a significant upgrade in all-terrain capability, all-weather performance, and efficiency to enhance your EV truck's driving experience.

The forum team spoke with the lead engineer on this project, and from what we've seen, significant research and development has gone into this tire, particularly regarding efficiency related to rolling resistance and aerodynamics, construction and compounding. To give F150 Lightning Forum an inside look, here are some key insights from our discussion:

• F-150 Lightning and similar EVs offer instant torque, blazingly quick acceleration, and weight significantly more, compared to their internal combustion engine (ICE) counterparts. Toyo has engineered the Open Country A/T III EV from the ground up with these characteristics in mind, while maintaining the Three-Peak Mountain Snowflake Symbol for severe snow service.

• The Open Country A/T III EV utilizes a patented AeroWing technology, resembling a spoiler at the bottom of the sidewall lug. Instead of creating downforce, this feature pushes air away from the tire. Further improving aerodynamics, Toyo has reduced the size of the chamfered shoulder block and used smooth, almost flush, high-contrast lettering on the sidewall, similar to the Toyo Open Country Q/T.

• The exact details of the rubber compound are proprietary, but it reportedly features an advanced, more evenly distributed full-silica compound. This translates to improved rolling resistance (more than 20% improvement), efficiency, and wet performance compared to the non-EV version.

• Speaking of rolling resistance, through testing, Toyo found that their Open Country A/T III EV is nearly on par with the OE Lightning highway-terrain tires, with only a 5% decrease in efficiency, which translates to roughly 5 miles of range difference. It's important to note that Toyo used their own F-150 Lightnings for testing.

The Open Country A/T III EV will be available in fifteen (15) LT-metric and P/Euro-metric sizes with XL, SL, and E load ranges. The first size, LT275/60R-20 (LR-E), is available now, with additional sizes following in Q3 and Q4 2024. Rim diameters include 18", 20", 22", and 24".

Additional highlights include:

• Balanced void ratio
• Increased tread block rigidity
• 50,000 mile treadwear warranty for LT sizes
• 500-miles or 45-day trial

As EV trucks and SUVs become increasingly popular for off-road exploration, aftermarket support is growing. The emergence of the Open Country A/T III EV reflects this trend, catering to adventurous EV owners.


What are your thoughts on the Toyo Open Country A/T III EV?

I'm on the fence; per their site, it's a 123-load rating and a pretty heavy tire, on par with the K02's. It's about 5+ pounds heavier than the factory Hankook. I would be more happy with a 115 load rating option and less weight.


Whats the availability? All the dealers I talked to cannot seem to get any information on availability.

how does a 5% decrease in efficiency result in 5 miles of reduced range? Last time I checked I got more than 100 miles on a full charge.

Generally, heavier-duty construction, like the LT LR-E in this case, leads to an increased weight compared to an SL or XL tire of the same size. When you compare the overall weight of the LT tire to an F250, the two are close, making the higher load range seem well suited for the Lightning. The heavier-duty construction should also provide improved stability and help with rolling resistance due to the higher pressure it requires.

According to our understanding, LT275/60R-20 tire inventory is currently being shipped to distributors. On our end, we are waiting for internal part numbers to be created. As soon as this happens, the Open Country A/T III EV will go live on our website.

For reference, the 275/60R-20 116 XL version is under development and is slated for release towards the latter half of this year.

The range loss from the testing was approximately 5 miles from 80% charge. In real world use, 5-10 miles range reduction is likely what owners can expect.

Interested to see some snow tests with this tire before I am sold.

Once Discount Tire obtains these tires, testing will be reflected in our tire guide. Also real world forum member reviews are always welcome!

How about road noise, I'm very happy with the quiet ride of my good year oem. That said if these good year are like my Ram after 20k miles they will be squirrelly in the rain.

The Toyo Open Country A/T3 EV is an all terrain tire and unlike the factory Highway Terrain, would stand to be a touch louder. Toyo has improved the wet performance with this new version and while we don't have any test data comparing the wet performance between the two, I'm confident it will perform well.

The Toyo Open Country A/T3 EV is an all terrain tire and unlike the factory H/T would stand to be a little bit noisier, however its traction in rain would be better. Of course tires are a product of compromise.

Are these available yet?

We have not received physical inventory as of yet but are expected too shortly. Once we have established article numbers in our stores system, it will reflect on our website. Thank you for your patience.

Snowflake rated?

Snowflake rated?

Yes according to Toyo, 3 peak rated

Getting these installed tomorrow, I can’t wait!

 

[Zprime29]

I've got about a year or so before I'll need new tires, but I'm keeping an eye on these. Can't wait to read what you think of them.
