Ford Lightning Platinum uses 275/50/22 tires and they are 115 XL
The GVWR rating for it is 8550 lbs, basically same as R1S/R1T at 8,532lbs
The Tow rating for the Ford Ligthning in Platinum Trim is 8500lbs, but other trims can go higher.
Based on the above, I would feel comfortable using a 115...
Rivian is now selling the NACS adapter for $225 on the website. I asked when my free one would arrive (Jun 2024 delivery for my Rivian) They said a large batch has arrived and they expect to deliver them by Jan.
From the rep at the Sonoma event. It will be in Aqua Dulce in north Los Angeles county. Will start after thanksgiving. The staff at Sonoma’s event is from all over the country and Rivian employees. Usually events like this are hosted by contractors.
From the hub at Venice. 20x8.5 et 48
Bolt pattern 5x5.5”
I don’t know the center bore
ram wheels do come in 20 and 22 with this bolt pattern but et closer to 28, so might work but wheel will stick out and widen the track
