Installed Toyo Open Country AT3 EV 116 T XL All-Terrain Tires

[Madtroniks]

Here is the initial pictures from the install.

Just driving 4 miles I got 1.92 mi per kWh. I would expect this to go up once I’ve driven 20+ miles instead of short trips.

I’ll drive more tonight and report back with proper efficiency numbers and once i get all tires to 50 lbs hot.

Here is a pic of the 51 PSI max pressure for the Toyo Tire Open Country A/T III EV 275 /65 R20 116H SL BSW version of the AT III EV.

I am running them at 48 lbs cold and 50 lbs hot on my Rivian R1S which weighs around 7,000 lbs.

I am seeing similar or slightly better range with these tires compared to stock Rivian Pirelli Scorpion All Terrain+.

1.80 - 1.9 mi/kWh on Highway at 73 mph and 2.25 - 2.45 mi/kWh around city at 40 mph.

Initial thought to me is the original Pirelli AT+ gripped better when making a fast turn.

Toyo does a good job holding on to twisty roads and initial grip from launch like Pirelli did.

The Toyo tires are quieter and rated at 65,000 mile with warranty and Pirelli is 50,000 mile tread wear warranty.

I’m happy with the tires overall compared to OEM Rivian Pirelli.

I love the 65,000 mile warranty, weight, efficiency and load / speed rating.

Here is some in town driving stats for Toyo 34” all terrain III EV tires.

Here is some highway driving stats for Toyo 34” all terrain III EV tires around 68 mph - 70 mph.

Load index 116 is for 2756 pounds, so putting the Toyos at 48 psi cold seems on the high side for a 7062 pound vehicle. I think the stock psi for the 20” on the Rivian is 44, I’d be inclined to test the Toyos there and see how they perform.

I increased the pressure on my 115 rated stock AT tires from the recommended 36 psi to 42 psi of the 116 tires. After reading a bunch of threads about the AT tires wearing prematurely on the edges it seems like the 36 psi number is low. At the higher PSI I have noticed a loss of traction if I full send in anything other than ideal conditions. It’s predictable, but the truck certainly gripped better at the lower PSI. I don’t have enough consistent miles to see if there is a difference in efficiency.

I run the Tesla Y a little lower than the recommended 42 psi, 39 psi gives a little better ride without a noticeable efficiency penalty.

Thanks for the detailed reply. I know when I ran pressure slightly lower it helped grip better at the expense of efficiency.

I will run some tests and let you know what works best for grip.

For efficiency Rivian recommends 48 PSI even though the stock tires mention 44 PSI as max.

Here is my door jamb plus weight details.

My stock tire is 116H.

I ran into the same issue on my 2021 Bronco, the stock tires were rated for 35 psi but the door sticker calls for 39 psi. I run those at 36 psi.

I have a ‘23 Lariat originally fitted with the 115T 36psi, but I just switched to Michelin LTX MS2 116H rating.

Should I be filling to 42 for the higher 116 load ratings? Now I’m really confused lol

How’s your range on those tires?

Interested in these. The price is borderline nauseating. The Toyo’s look neat, but the Rivian spec Goodyear Wrangler Territory AT is $573 less per set. Maybe I need to search marketplace for some Rivian take offs.

Just got mine on yesterday and I LOVE them! They are amazing! No road noise increase that I can even hear. And I was trying real hard to hear any difference. I leave the radio off or on super low almost always. It’s calming lol. They ride way better too! The Wranglers were too soft under the weight even at 45psi. Truck always felt sloshy. These feel like they are solid and responsive but STIll somehow don’t ride rough at all. They look incredible! Go to the dealer! Ford did the buy three get one free (up to $250) deal and only $363 ea. when everyone else in town wanted $400 ea. with nothing free. And you’ll get Ford reward points from dealer. Price is worth it to me as well because they are 65k mile tires. The stock felt like they were wearing quick. Even with easy driving and high pressure . Cant say enough good things about these Toyo EV’s! Go get them…you’ll thank me later!

I just got back from a trip to northern VT where I used the Lightning on the rural hard pack dirt roads with factory A/T tires at 40 psi. I was surprised how well it did overall. My wife was less than pleased with the speeds I was doing, especially in the rain, but the tires were predicable enough. I have 26 months left on my lease, as much as I’d like to upgrade the tires I’m not sure it’s worth the investment. I’ll inquire with the local dealer and see if they can offer the buy 3 get 1 deal, thanks for the tip on that. The Toyo’s do look awesome.
