Toyo Open Country A/T III EV Tires (LT275/65R20) - Fantastic (Review & Efficiency Stats)

[Zorg]

Our lifetime average is about 2 mpKWh. Road trips at 80ish mph and lots of trips between bay and Truckee at 75.

Oops, forgot to look there. Checked Discount Tire and a few others. I think this is what I'll go with this spring since I'll only do light off-roading with my R1T. Mileage has got to be better than the LT option(s) with 13 lbs less weight.

I haven't been able to pull up the Toyo ATIII EV at Discount Tire. The only option there is the LT ATIII.

You can probably have your local Discount Tire shop order them for you. They should match the Tire Rack price too. This is what I plan to do if DT doesn't stock them after I eek out a few more miles on my OEM Pirelli tires.

Lots of talk and speculation over results for the SL... but one glaring thing being overlooked: they have only been available since late last year, less than three months. What we're missing is warm weather conditions. Numbers known so far are simply inconclusive. 10-15% better than LT does seem a bit optimistic, but no one will know for sure until summer. For now, it makes more sense to compare like-for-like, to the Pirelli ATs' number in winter.

Toyo's part number for the SLs are on their product page, refer to that if you need to have your local DT special order them.

Drove today in deep snow (parking lot not plowed after a good dump) and tires handled it no problem.

Very icy here in Colorado. My Pirellis at 18K mi did not do well, especially with lateral slip. Coupled with the fact that they have become intolerably loud in the last few thousand miles, I am getting these Toyo LTs installed next week and will update after an adequate sampling of miles. FYI Discount Tire has these in stock at some stores and there is an $80 rebate if purchased before Feb 18 from Toyo. Item 178205 is the LT version of the OC A/T III EV.

Edit: Replaced today. More solid and secure than SL Pirellis and better on ice so far. 16F here so efficiency is less. DT raved about these but I think they meant the non-EV version as both the SL and LT have just recently been available. Will update after a few hundred miles but for now I'm happy with a safer tire for off roading.

Edit 2: I reached out to Toyo today and asked them what the psi should be with the change from an SL to an E tire in the 20" size. Discount Tire said 50psi. Toyo said based upon the OEM Pirelli 116H tire at 48psi that the Toyo LT version should be 46psi cold. Ironically even though DT inflated them to 50psi it's -5F here today and the TMS is measuring 46psi. Efficiency is poor but it's freaking cold so I'll wait to make any adjustments or formulate an opinion until it thaws.

I am considering these tires for my R1S. Any further detailed accounts for daily driving and snow?

I too live in Colorado.

Do they still feel reasonably sporty or are they just big wallowy tires?

Daily driving in TX has been excellent. I find them quite sporty for their class. They have better wet weather traction than I initially assumed but I’d still be cautious taking hard corners on wet surfaces at speed. No experience in snow yet.

Update on my Toyo OC A/T III EV LT tires after 450 miles:

Installed on a -5 degree day here in Colorado so started concerningly at 1.5miles/kWh. Now at 2.05 and climbing (OEM Pirelli 2.2 over 17K miles). I think after the weather warms the Toyo will be a wash or slightly better than the Pirelli, which is fantastic because it's an LT tire (Pirelli is SL). I off road a lot so having a more durable tire is important.

Performance wise, as others have already pointed out, the Toyo is a beefier tire: much better off road, much better on ice/snow (although not as good as dedicated winters) and more "solid". The Toyo doesn't feel quite as sporty as the Pirelli but that is highly subjective and not important to me.

I will update after 1000 miles, but this was a significant upgrade and performs better than the OEM Pirelli in every metric that is important to me. If you want better snow/ice performance and safer off road than the OEM Pirelli this LT tire will satisfy with little to no decrease in efficiency.

These are awesome numbers. I can’t wait for someone to try the Toyo SLs!

I’m on the fence about LT vs SL. Trailering is pushing me towards LT, but I don’t do it that often…

(Also still on the fence between the Toyos and the Goodyears.)

I scoured the internet for consistent reviews (especially efficiency data) regarding the SLs and everything I could see did not show a definitive improvement over OEM or the LT. Some have predicted the SL should have a 20% improvement over LT but tire efficiency can be tricky to predict. Even if the SL is 10% more efficient than the LT I am still happy with my choice as it provides much more solid footing off road. Also the SL tire width is 0.5" more narrow than either the LT (9.1") and OEM Pirelli (also 9.1").

Regarding the Goodyears, because they are a smaller (33" vs 34") tire they should have even better efficiency with excellent performance. I did not want to give up the 1/2" clearance.

Also remember that my efficiency numbers are at elevation, so adjust down to convert to lower elevations.

I’m leaning slightly towards the Goodyears. Finally saw them in person at the Colorado Springs service center, and they looked so much better than I expected from photos. We‘re driving back and forth between Maryland and New Mexico multiple times a year, so efficiency is important, but so is handling the dirt and worse roads we deal with in New Mexico, potentially with snow and ice.

I don't care as much about off-road use honestly. I just want good efficiency and a comfortable ride - and I would love to keep the beefy look. Should I look at a different tire?

IMO, this is a simple one. Toyos are full-on ATs. The Goodyears are AS with a bit of AT trait mixed in. So it's down to how much and what level of off-roading you do, plus the appearance of a true AT.

The now factory standard Goodyear Territory AT RIV. 275/60R20. Or, the Michelin Defender LTX MS2.

This seems very promising. I was getting a little under 2 for the brief time I had my Pirellis on in October. I'm already noticing my numbers going up as the weather warms up this spring with my Nokian snows.

Wasn't there another post that showed the range on the SLs being not very good?
