20" Inch Atomic Wheels AWZZ wheels with Toyo Open Country A/T III EV LT275/60R20 installed!

Yesterday, after racking my brain for what seemed like weeks on what I wanted, I received the AWZZ and Toyo Open Country A/T III EV LT275/60R20 wheel and tire setup from Atomic Wheels.

Last fall, I sold my stock 20” bright/Pirelli tires and installed a 20” aftermarket and winter wheel setup for the upcoming Colorado winter. With the weather moving toward warmer days ahead, I wanted to capitalize on the opportunity to switch to a lighter wheel while prioritizing efficiency gains and opting for a reliable AT tire that I’ve had experience with and trusted in the past. In fact, I currently have the same (non-EV) tire on my 2019 Tundra, and it performs exceptionally well in snowy conditions and as a year-round tire. The combination of a lighter setup and the 2026.06 release with a wheel/tire swap seems like a win-win. Ohh, and unlocking more miles per full charge when I need it!

Let me just say that Santiago and the Atomic team were incredibly knowledgeable, patient, and responsive throughout the research and exploration process. Thank you, Atomic team! I went back and forth on several of their designs before finally deciding on the AWZZ in Satin Black. And now that they’re installed, I have no regrets. I love the look of this combo…sleek yet aggressive.

I haven’t received the OTA to 2025.06 yet, so I can’t recalibrate the R1S to the correct configuration just yet. However, I’m already enjoying the significant increase in efficiency (2.6 mi/kWh) on this warm Colorado day.

I’ll update this post in the coming weeks with more accurate numbers after the software update and a series of upcoming mountain trips.

I also have a custom wheel order in to Atomic wheels and we are going thru the final design iterations.

I have an 2025 LA silver stealth ppf wrapped R1S with a chrome delete (I took advantage of a stock vehicle) and had the calipers wrapped in heat resistant yellow caliper wrap (looks factory but glows at night, I haven’t taken any taken any night photos yet). I say all that to say this is a gorgeous preview of what my Rivian will look like soon (i’m aware the color is different but it’s close enough to give the visualization).

omg it’s so orgasmically beautiful congratulations to US!
