Toyo Open Country AT3 EV 17,000 Mile Review on the Rivian R1T

After 17,000 miles on the Toyo Open Country AT3 EVs, I can confidently say they are one of the best tire choices for Rivian R1T owners. I have previously run the stock Pirelli Scorpions and the Falken Wildpeak AT4Ws, and the Toyos strike the best balance of efficiency, durability, and all-terrain performance.

The stock Pirelli Scorpions wear quickly and are notorious for punctures. The Falkens are tougher and provide great traction but are heavier, and in my experience they caused balancing issues. The Toyo AT3 EVs are built specifically for electric vehicles, and that difference shows in daily use.

The AT3 EV starts with 15/32" of tread depth, and after 17,000 miles of road trips, forest trails, and off-road use, mine are still sitting at 13/32". That is impressive treadwear for an EV truck that puts extra stress on tires due to weight and torque.

What sets the EV version apart from the standard AT3 is the design. The AeroWing sidewall lugs improve aerodynamics, while the compound and reinforced construction lower rolling resistance and handle EV torque without sidewall squish. They are lighter than the Falkens, which helps efficiency, but still tough enough to handle solo adventures where puncture resistance matters. I run the 126 load rating for that extra confidence.

On-road, road noise is there but manageable, especially compared to wind noise from my Super Pacific setup. Off-road, they grip well in mud, gravel, snow, and sand, and they have not let me down when traction matters.

For Rivian owners looking for a tire that performs better than stock, rivals the Falkens, and is tuned for EV efficiency, the Toyo Open Country AT3 EV is my top recommendation. They start deep, wear slow, and balance strength with range in a way few all-terrains do.

If you want a tire that can handle daily driving and serious adventures, the Toyo Open Country AT3 EV will not let you down.
